▼ Subfamily Microgastrinae (Hymenoptera: Braconidae) is one of the largest subfamilies of parasitoid wasps, both in terms of number of described species as well as estimated total number of species. Containing ~57 genera and exclusively attacking Lepidoptera, most of the diversity is concentrated within a few very large genera, with many smaller genera, including Xanthomicrogaster Cameron, 1911, existing with unknown morphological boundaries, life histories, and habitat use information. Containing only four described species, Xanthomicrogaster is one of the smallest genera, with extremely little information known. In addition to this lack of knowledge, Xanthomicrogaster is an extremely rarely collected genus, both in Malaise traps and rearing projects.
Through the large scale efforts of the Área de Conservación Guanacaste (ACG) project in Costa Rica, over 50 specimens of Xanthomicrogaster have been collected, both through Malaise traps and caterpillar rearing. In addition to these specimens, borrowed material of undescribed Xanthomicrogaster species from the Canadian National Collection (CNC) and Texas A&M University insect collection (TAMU) is examined in order to understand the variation and geographic range of the genus. Previous descriptions of the genus and the recognized species are examined and placed into context using the material from across the geographic range. Seven species are newly described here from the ACG project, identified using morphology, DNA sequences (COI, wingless, and 28S rDNA), and host caterpillar with host plant records. The morphological boundaries of the genus are proposed, and a dichotomous key to world species is presented to facilitate identification and future description of species. Two
molecular phylogenies are produced, using appropriate outgroups: one for all newly described species using three genes, and one for all Xanthomicrogaster specimens obtained from the ACG project using the COI barcode region.
Host caterpillar use with host plant records is examined in the context of the phylogeny, revealing that Xanthomicrogaster specialize on concealed hosts, especially within superfamily Gelechioidea (Lepidoptera). In addition, sexual dimorphism is examined for the first time, as associations could be made using COI barcode information, revealing that males are often darker than females and are never collected in Malaise traps.
Color patterns in Xanthomicrogaster are examined, especially as they vary by sex, geography, and phylogeny. The geographic range of Xanthomicrogaster is strictly Neotropical, apparently restricted by the Sierra Madre del Sur range in Mexico and the Andes between Argentina and Chile. In addition, the genus Xanthomicrogaster occurs in Trinidad, but it is unknown if its range extends to the island of Tobago or beyond. In terms of elevation, specimens of Xanthomicrogaster have been collected from 13 m to 1600+ m. This revision increases the knowledge about Xanthomicrogaster, synthesizing research from the past 100 years and setting the stage for future…

The Evolution of Wahlenbergia (Campanulaceae) in Australasia.

▼ Wahlenbergia is a large genus of flowering plants within the family Campanulaceae. In this thesis the first
molecular phylogeny of Wahlenbergia was reconstructed from approximately 20% of the genus, based on the nuclear ribosomal ITS (nrITS) DNA
marker and the chloroplast trnL-F DNA marker, with samples from South Africa, Europe, Australia and New Zealand. Additionally a large phylogeny with increased within-species sampling focusing on addressing taxonomic questions among the 45
Australasian species of Wahlenbergia was also reconstructed based on nrITS and trnL-F, plus an additional chloroplast DNA marker, trnK. Relationships and species limits of the New Zealand species of Wahlenbergia were further analysed using
amplified fragment length polymorphisms (AFLPs).
Wahlenbergia was found to be polyphyletic, though most of the species form a clade. Tree topologies and
molecular dating analysis showed that the genus originated in South Africa about 16.2 million years ago (mya), then dispersed to Australasia before radiating there about 3.7 mya, thus refuting the hypothesis of Gondwanan vicariance for the Australasian species. Two dispersals from Australia to New Zealand are hypothesised, one leading to a radiation of species with the rhizomatous growth from about 1.0 mya and the other leading to a radiation of species with the radicate growth form 0.49 mya, although the radicate species might not form a clade. Low levels of genetic variation among individuals from Australia and New Zealand was revealed with all markers, and the phylogenies were poorly resolved as a result. The low genetic diversity is probably due to rapid and recent evolution during a
period of geological and climatic change, coupled with incomplete lineage sorting and hybridisation. Phylogenies reconstructed using AFLPs were also poorly resolved, although AFLPs were found to be useful for species delimitation, as has been shown in studies of other plant groups. Despite the poor resolution, several morphological species and subspecies were recovered as monophyletic with DNA sequence data, notably the morphologically
distinctive New Zealand W. cartilaginea, W. matthewsii and W. congesta subsp. congesta. Further research into species boundaries within the W. albomarginata/W. pygmaea complex is needed. Members of the New Zealand lowland radicate W.
gracilis complex may all belong to the same morphologically variable species, although further research is needed to justify such a taxonomic change. The other New Zealand radicate species, W. vernicosa, is probably a separately evolving lineage, and is not conspecific with the Australian W. littoricola.

▼ The advent of large-scale genomic sequencing is providing researchers with an unparalleled wealth of information which can be used to elucidate the evolutionary relationships of living organisms. The newly available genome sequence data have enabled the use of comparative genomic techniques for the identification of novel molecular signatures, shared uniquely by evolutionarily related groups of organisms: conserved signature indels (CSIs) and conserved signature proteins (CSPs). These signatures allow for the unambiguous delineation of the prokaryotic taxa, independent of gene and genome based phylogenetic trees, and provide insights into novel aspects of their evolutionary relationships. The phylum Spirochaetes and the class Betaproteobacteria are large, diverse groups of bacteria, containing many important pathogenic and environmental organisms, which are classified primarily on the basis of 16S rRNA gene analysis. Here, I describe phylogenetic analyses of the phylum Spirochaetes based on genome derived molecular signatures. These analyses have yielded substantial evidence for differentiation between the three main sequenced groups of organisms within the phylum Spirochaetes and between the genus Borrelia from other closely related Spirochaetes. These findings have prompted a proposal to create three new orders and a new family within the phylum. These analyses have also supported the differentiation of two clinically distinct groups within the genus Borrelia and a proposal to divide the genus Borrelia into two genera. The use of molecular signatures and phylogenetic analysis of major groups within the class Betaproteobacteria are also described. The analyses of the order Neisseriales within this class resulted in a division of the order into two families, while the analyses of the genus Burkholderia supported the differentiation of the clinically relevant members of the genus Burkholderia from the plant-beneficial and environmental Burkholderia and a proposal to divide the genus into two genera. I also describe the use of phylogenomic techniques and molecular signatures to differentiate the seven main groups within the order Enterobacteriales and the integrated software pipeline used to produce the supermatrix based phylogenomic tree and genome distance calculations in the analysis of the order Enterobacteriales. The molecular signatures described in this thesis represent powerful new tools for evolutionary and systematic studies. Additionally, due to their taxon specificity, these molecular signatures are novel diagnostic markers for their specified group. Further analyses of these molecular signatures should lead to the discovery of novel functions and biological characteristics, mediated by CSIs and CSPs, which will provide important insights into the physiology, evolution, and adaptations of these groups.

▼ Diversas espécies de mosquitos do gênero Culex Linnaeus são vetores de nematóides que causam filariose linfática (Wuchereria bancrofti) e de vários arbovírus, incluindo o Vírus do Nilo Ocidental (VNO) que causa encefelites em animais e humanos. Embora seja o maior gênero da família Culicidae, com 763 espécies conhecidas, pouco se sabe sobre a taxonomia e as relações filogenéticas do grupo. Considerando-se a grande diversidade de espécies do gênero Culex, as dificuldades para a identificação morfológica, devidas principalmente ao fato das fêmeas serem morfologicamente muito similares, o presente trabalho teve como objetivos: (1) Solucionar problemas relacionados à nomenclatura; (2) Estimar as relações filogenéticas entre espécies de diferentes subgêneros; (3) Examinar o monofiletismo de subgêneros da Região Neotropical; (4) Estimar as relações evolutivas entre subgêneros neotropicais; (5) Estimar a posição filogenética do gênero Lutzia em relação à Culex; (6) Discutir sobre a utilização do gene citocromo c oxidase da subunidade I (COI) para o gênero Culex. Foram analisadas sequências correspondentes a um fragmento de 478 pares de bases do gene COI de 36 indivíduos pertencentes a 16 espécies do gênero Culex. Foram avaliadas espécies de quatro subgêneros, Culex, Phenacomyia, Melanoconion e Microculex e uma espécie do gênero Lutzia. As sequências do gene COI foram comparadas através das análises de Máxima Parcimônia, Máxima Verossimilhança e Bayesiana. Os resultados das análises das sequências de COI, utilizando ao modelo de Kimura 2-parâmetros, de Culex dolosus, Culex mollis e Culex imitator, demonstram a presença de divergências intraespecíficas altas (3,1%, 2,3% e 3,5%, respectivamente). Os valores do modelo Kimura 2-parâmetros indicam que esses taxa podem representar complexos de espécies. As topologias de MV, MP e Bayesiana mostraram que tanto o gênero Culex como o subgênero Culex são parafiléticos, pois o primeiro não inclui o gênero Lutzia e o segundo exclui o Phenacomyia. Os resultados indicam que Lutzia é subgênero de Culex e Phenacomyia um grupo monofilético do subgênero Culex. O marcador molecular COI foi de fácil utilização e análise, provando ser ferramenta útil para estudos filogenéticos e para a taxonomia molecular de Culex
Species of the genus Culex Linnaeus mosquitoes have been pointed out as the main vectors of lymphatic filariases. Furthermore, they are important vectors of encephalitis across the world, including the West Nile Virus. Although being the major genus in Culicidae family, with 763 valid species, Culex, in a taxonomic and phylogenetic sense, is one of the least known. Considering the great diversity of species of mosquitoes in this genus, and the fact that females of several species are vary similar morphologically, the present study aimed to: (1) Solve problems related to nomenclature (2) estimate the phylogenetic relationships of species used in the work; (3) examine the monophyly of subgenera of the Neotropical Region; (4) estimate the evolutionary relationships between neotropical…

Systematics and diversity of Ichneumonidae, with an emphasis

▼ Ichneumonidae are the most species-rich family of
parasitic Hymenoptera and are important for regulating populations
of other arthropods. However, with an estimated 75% of species
undescribed, we lack fundamental information about their taxonomy,
ecology, and distributions. Using two different groups of
Ichneumonidae, I address each of these issues in this thesis. In
Chapters 2 – 4, I focus on the taxonomically-neglected genus
Ophion. I provide the first phylogenetic hypothesis of Ophion based
on molecular data (COI, ITS2 and 28S) and divide the genus into ten
provisional species-groups (Chapter 2). I also describe the
secondary structure of ITS2 for the first time in Ichneumonidae,
and discuss its potential to inform phylogenetic inference in
Ophion (Chapters 2, 3). I investigate the diversity of Ophion at
the species level by comparing quantitative species delimitation
methods with each other and with morphologically-defined species
(Chapter 3). The total number of delimited species is dependent on
the method and parameters used; however all methods agree that
there is a wealth of undescribed diversity in Nearctic Ophion.
Finally, I revise the Nearctic species within the newly defined
Ophion scutellaris species-group (Chapter 4). An integrative
analysis of DNA, geometric wing morphometrics, classical
morphometrics and morphology indicates that this species-group
contains a minimum of seven species in Canada, although the full
diversity of the group has likely not been sampled. Ophion clave
sp. n., O. aureus sp. n., O. brevipunctatus sp. n., O. dombroskii
sp. n., O. keala sp. n., and O. importunus sp. n. are described.
Once species have names, it is possible to address other
fundamental questions about their distribution and ecology. I
conducted a survey of Ichneumonidae in a boreal deciduous forest,
with an emphasis on Pimplinae, Poemeniinae, and Rhyssinae.
Responses to forest harvesting were weak, but there is evidence
that the community composition at the species level is correlated
with shrub composition. Even within this relatively well-known
group, there is much unexplored diversity. Any nomenclatural
changes or new taxa proposed in this thesis should not be
considered valid until published in primary journals as defined by
the ICZN (International Commission on Zoological Nomenclature
1999).

▼ The aquatic beetle family Noteridae (Coleoptera: Adephaga) comprises a group with poorly studied diversity that has received limited systematic study. Despite the corroboration of multiple phylogenic reconstructions, many relationships within Noteridae remain poorly supported or unresolved. Here I address the questions surrounding the systematics of Noteridae in three ways. First, a review of previously constructed noterid phylogenies is presented and methods, variation in recovered relationships and the current classification of Noteridae are explored. Second, a phylogeny of Noteridae is inferred based on the analysis of DNA sequence data of five gene fragments: COI, H3, 16S, 18S, and 28S. Our taxon sampling of Noteridae is the most robust of any phylogenetic investigation of Noteridae to date and includes representatives for 16 of the 17 current noterid genera. Bayesian and Maximum likelihood analyses produce highly supported trees that strongly contradict previous studies. Our results recover the monophyly of the following higher level groups: (1). Meruidae + Noteridae, though the exact nature of this relationship is unresolved; (2) Phreatodytinae + Notomicrinae; and (3) Noterinae. All known genera are found to be monophyletic except Hydrocanthus Say, found paraphyletic with respect to Mesonoterus Sharp and Prionohydrus Gomez & Miller, and Suphisellus Crotch, found to be paraphyletic with respect to Pronoterus. Thus the following changes in classification and
taxonomy are proposed: the subgenus Sternocanthus Guignot is resurrected from synonymy stat. rev. and elevated to the genus rank stat. n. to contain Old World members of the genus Hydrocanthus sensu lato; and Pronoterus Sharp syn. n. is placed in synonymy with Suphisellus Crotch. All tribes within the Noterinae are recovered as paraphyletic or invalid due to synonymy and the a revised classification is thus proposed: (1) Noterini Thomson sensu n. is redefined contain the genera Noterus Clairville and Neohydrocoptus Satô, thus including Neohydrocoptini Zalat et al. syn. n. as a junior synonym ;(2) Tonerini Miller sensu n. is redefined to hold the genera Synchortus Sharp, Tonerus Miller, and Liocanthydrus Guignot; (4) Renotini trib. n. is erected to contain the genus Renotus Guignot; (5) Suphisini Sharp rev. stat. is resurrected from synonymy to hold the genera Suphis Aubé, Canthysellus Baca & Toledo gen. n., Suphisellus Crotch incl. Pronoterus Sharp, and a tentative new noterid genus; and (6) Hydrocanthini Sharp stat. rev. is resurrected from synonymy to hold the genera Canthydrus Sharp, Sternocanthus Guignot, Hydrocanthus Say, Mesonoterus Sharp and Prionohydrus Gomez & Miller. A discussion of relationships, classification and morphology is presented. Finally, the poor documentation of noterid diversity is addressed with the description of the genus Canthysellus Baca & Toledo gen. n., here erected to contain three species Canthysellus buqueti (Laporte, 1835), C. sipaliwini sp. n. and C. peruanus sp. n.

▼ Pinus radiata is one of the most important species of forestry plantation worldwide and many pests and diseases have followed the expansion of this species around the globe. Tasmanian P. radiata plantations suffer from a needle cast disease referred to as spring needle cast (SNC) which has similar symptoms to Cyclaneusma needle cast, a serious disease in New Zealand. Stands with moderate or severe SNC can be expected to suffer potential losses in clear-fall volume. The aetiology of SNC is poorly understood and has long been a point of debate between Tasmania and New Zealand foresters with the New Zealanders attributing SNC to Cyclaneusma minus. Tasmanian research in the 90s proposed that SNC is caused by one or a suite of fungi that are triggered by an unknown environmental stress. Three species of fungi have been putatively associated with SNC, i.e. Lophodermium pinastri, Strasseria geniculata and C. minus.
Understanding endophyte diversity is crucial for determining their role in forest health. Endophytes are increasingly recognized for having a role in plant-pathogen interactions leading to disease. In particular, they may play an important role in determining the presence of a disease such as SNC, which does not appear to have a single pathogenic causal agent and which may be associated with environmental stress. The main objective of this study was therefore to identify needle fungal communities which are associated with both healthy and SNC-affected trees in P. radiata plantations in Tasmania. Needle fungi have been extensively studied in conifers but rarely in P. radiata.

▼ Cyphelloid fungi are, compared to their gilled relatives, poorly studied and understood. Within the tribe Resupinateae (which includes the genera Resupinatus, Stigmatolemma, Aphyllotus and Stromatocyphella), little is known about the evolution of the cyphelloid fruit body form. How many times has this reduced morphology evolved within the group? Do all cyphelloid members that are currently treated in this group belong there? Are there other described species of cyphelloid fungi currently treated in other genera that belong within the Resupinateae? This study presents phylogenies of the cyphelloid and small lamellate members of the Resupinateae based on rDNA sequences to illustrate the evolution of reduced basidiomata. This study also provides an analysis of traditional morphological characters used to distinguish species (fruit body colour and size, and spore size, shape, ornamentation and colour) and compares morphological and DNA-based classifications to illustrate a common problem in cyphelloid taxonomy: because these forms are so rarely studied, the incidence of synonymy within the group is high. The few herbarium specimens associated with many species names may lead to false impressions of host specificity or restricted geographic ranges for species that are more generalist or cosmopolitan. Some previously suggested synonymies and reports are based on misidentifications and mask genuine patterns of hosts and geographic range. Based on the phylogenetic analysis of the group, all members of the Resupinateae fall into a single genus, Resupinatus, (Stigmatolemma and Stromatocyphella are synonyms), whereas the genus Aphyllotus is excluded. This study highlights the significance of herbaria as repositories of unknown and undocumented biodiversity, and shows that the evolution of different fruit body morphologies in the Fungi is not a linear pattern of simple to complex.

▼ Molecular phylogenetics has clarified the limits of the angiosperm family Loganiaceae, and of the Australasian-Pacific tribe Loganieae. However, generic circumscriptions within Loganieae require clarification. A molecular phylogeny confirmed the monophyly of Mitrasacme, with Phyllangium and Schizacme placed sister to each other and to Mitrasacme. The monophyly of Schizacme, including New Zealand taxa, was confirmed, and a review of Schizacme is presented. Mitreola minima was placed sister to Mitrasacme and its segregates, rather than with other members of Mitreola. A new monotypic genus, Adelphacme, is erected, and the morphological characters distinguishing it from Mitreola, Mitrasacme, Phyllangium and Schizacme are presented. Labordia was nested within Geniostoma. New combinations within Geniostoma are provided for sampled taxa. Logania sect. Logania and L. sect. Stomandra (syn. of Orianthera) were each monophyletic but Logania was non-monophyletic.
Mitrasacme is the largest genus in Loganieae (c. 54 spp.). Its geographic range extends from Asia, Malesia and New Caledonia to southeastern Australia, but is centred in the Australian Monsoon Tropics. Species limits and the subgeneric classification of Mitrasacme were tested in a species-level molecular phylogeny. The monophyly of Mitrasacme, and relationships between Adelphacme, Mitrasacme, Phyllangium and Schizacme were confirmed. It is proposed that these four closely related genera be referred to as the Mitrasacme alliance. The current subgeneric classification in Mitrasacme is not supported, but a new subgeneric classification is hindered by morphological homoplasy and nested evolution. Three independent lineages in Mitrasacme extend into temperate eastern Australia, and multiple recent dispersals into Malesia and Asia are postulated. Morphological evolution in Mitrasacme might reflect adaptation to stochastic rainfall, oligotrophic soils and diverse insect pollinators in the Australian Monsoon Tropics.

▼ Os lagostins de água doce sulamericanos (Família Parastacidae) são representados por três gêneros: Parastacus Huxley, 1879, Samastacus Riek, 1971 and Virilastacus Hobbs, 1991. Esse grupo é distribuído no Sul do Brasil (Rio Grande do Sul and Santa Catarina), Uruguai, Argentina e Chile. Os objetivos dessa tese foram revisar a taxonomia do gênero Parastacus e investigar a sua monofilia e relações filogenéticas entre suas espécies e entre os outros gêneros sulamericanos. Para esse propósito, várias coleções e museus ao redor do mundo foram analisados (Brasil, Argentina, Uruguai, Chile, Estados Unidos, Alemanha, Holanda, Inglaterra e França) em adição a coletas realizadas entre Março de 2013 a Setembro de 2016. Os espécimes foram analisados em estereomicroscópio e os desenhos foram preparados com auxílio de camara lucida. Para as análises genéticas, uma abordagem multigênica foi utilizada com dois marcadores mitocondriais (Cox1 e 16S) e um nuclear (28S). A análise filogenética foi realizada por Inferência Bayesiana e a distância genética p também foi calculada. Adicionalmente, o risco de extinção foi assessado para algumas espécies de acordo com o sub-critério B1 da IUCN que leva em consideração a estimativa da Área de Extenção de Ocorrência. Oito espécies foram redescritas: Parastacus brasiliensis (von Martens, 1869), P. defossus Faxon, 1898, P. laevigatus Buckup & Rossi, 1980, P. pilimanus (Von Martens, 1869), P. pugnax (Poepigg, 1835), P. promatensis Fontoura & Conter, 2008 e P. varicosus Faxon, 1898. Um novo gênero foi proposto para alocar a espécie P. nicoleti (Philippi, 1882) que também foi redescrita. Treze novas espécies foram descritas. Assim como, chaves de identificação, descrições, diagnoses, sinonímias e mapas de distribuição foram providos. As árvores filogenéticas resultantes corroboraram com a monofilia de Parastacus e do clado sulamericano, além de dar suporte para o estabelecimento de um novo gênero e novas espécies. Com essa tese, o aumento da riqueza específica para Parastacus é de mais de 150% e as novas informações sobre habitat e distribuição trarão suporte para futuros estudos de conservação e manejo.

▼ Two species of Chrysaora are described from the northern Benguela ecosystem: C. fulgida and C. africana. These species can be diagnosed by a combination of morphological features including lappet and tentacle number, shape of lappets, colouration patterns (alive), shape of the proximal portion of radial septa, gastrovascular pouch shape, point of attachment of gonads and the presence or absence of small raised nematocyst warts on the exumbrellar surface. Objective, quantitative statistical analyses coupled with
molecular sequence data support the qualitative morphological dissimilarity observed, as these analyses unambiguously diagnose C. fulgida and C. africana as two distinct species. There is a strong superficial resemblance between the C. fulgida material described here and the preserved specimens of C. hysoscella examined at the Natural History Museum, London. Thorough investigation does however allow the separation of these two species. Morphological features found to be dissimilar were the proximal portion of the manubrium, gastrovascular pouch shape and the presence or absence of sperm sacs. Objective, quantitative statistical analyses support these findings. Nuclear sequence variation suggests considerable divergence between the two species but additional
molecular work is needed.

▼ Zieria (Anthophyta: Rutaceae) is a predominately Australian genus of shrubs and small trees, consisting of 59 Australian species and one species endemic to New Caledonia. Although there has been considerable taxonomic revision of this genus in recent decades, largely based on morphology, a comprehensive molecular phylogenetic study that would include as many currently-recognised taxa as possible was clearly needed. Using five chloroplast markers (rpl32–trnL, trnL–F, trnQ–5'rps16, trnS–G and 3'trnV– ndhC) and two nuclear DNA markers (ITS and ETS) this study undertook phylogenetic analyses in order to understand relationships, evolutionary processes and taxonomic issues in Zieria, and to interpret biogeographic patterns. Both Bayesian inference and maximum parsimony methods were employed. Almost all species of Zieria were represented in separate analyses of the cpDNA and nrDNA datasets, with the monotypic sister genus Neobyrnesia used as the outgroup. The results show that relationships within Zieria are complex; widespread incongruence was revealed between cpDNA, nrDNA and currently recognised taxa. A combination of factors is suggested to explain this, including regional cpDNA introgression (chloroplast capture) and incomplete lineage sorting, and the need for taxonomic revision of some taxa. The nrDNA provided greater support for monophyly of species than cpDNA, and potentially a better indication of phylogeny. However, deeply divergent paralogues of nrDNA were detected in some taxa, making the assessment of phylogenetic relationships more challenging, and highlighting some possible pitfalls in using nrDNA for phylogenetic reconstructions.
The phylogenetic relationship of Australian taxa and Z. chevalieri, the single endemic New Caledonian species, is of particular interest in terms of the long-standing debate over the history of New Caledonia and its flora. The placement of Z. chevalieri differed between cpDNA and nrDNA trees. The cpDNA phylogeny placed Z. chevalieri as sister to all other species in the genus, suggesting that the earliest divergence was between lineages of New Caledonia and Australia, and that differentiation of species occurred through vicariance. In contrast, Z. chevalieri was placed higher in the nrDNA tree, which could suggest later dispersal, over water or via past exposed land in the Tasman Sea rather than older vicariance between Australia and New Caledonia. However, the results did not favour one hypothesis over another, and the debate will continue.
A phylogeographic study of one widespread species, Zieria arborescens, was also undertaken, focusing on populations in the wet forests of Victoria and Tasmania. The cpDNA was not highly informative but provided some evidence of Tasmanian–eastern Victorian connections, interpreted as past geographic connectivity during periods of low sea-level now severed by Bass Strait.
Finally, a number of taxonomic issues arising from the results of this project are discussed, and recommendations are made for reappraising and possibly…

▼ The class Gammaproteobacteria and its different main orders are currently classified solely on the basis of their branching in phylogenetic trees. In most cases, no molecular, biochemical or physiological characteristics are known for their demarcation. The availability of genomic sequence data has enabled the discovery of two types of molecular characteristics in the forms of Conserved Signature Indels (CSIs) and Conserved Signature Proteins (CSPs) that provide novel means for identification and demarcation of prokaryotes. In the following work, numerous CSIs and CSPs have been identified for different orders within the class Gammaproteobacteria, with particular focus on Pasteurellales, Xanthomonadales and “Enterobacteriales”. The order Pasteurellales contains a single family, Pasteurellaceae, harbouring many important human and animal pathogens. We have discovered a large number of novel CSIs that are specific for either all Pasteurellales or several distinct clades within this order of bacteria. Based upon these CSIs, we have been able to demarcate the “sensu stricto” members of the genera Actinobacillus, Haemophilus, and Pasteurella that are presently polyphyletic. Similarly, we have identified numerous CSIs for the phytopathogens-containing order Xanthomonadales and have used them in conjunction with phylogenetic analyses for the taxonomic reorganization of the members of this order. The Xanthomonadales species that branched monophyletically and shared CSIs were grouped into one of two families within the order Xanthomonadales while the other species were transferred to a new order. This work also reports many CSIs and CSPs for the phytopathogenic genera Dickeya, Pectobacterium and Brenneria from the order “Enterobacteriales” and this work also discusses the usefulness of CSIs and CSPs for understanding prokaryotic systematics and taxonomy. Additionally, based upon the species distribution of CSIs, we have also examined the impact of LGT on prokaryotic phylogeny/systematics. The extensive work on CSIs that we have reviewed supports the notion that the genetic changes responsible for them have been inherited predominantly in a vertical manner following Darwinian mode of evolution. The molecular markers discovered in this work, because of their taxa specificities, provide valuable means for genetic and biochemical studies that should lead to discovery of novel biochemical and physiological characteristics of the studied groups of bacteria and they also provide new tools for their diagnostics and as potential drug targets for these bacteria.

▼ The subfamily Phasiinae (Diptera: Tachinidae) is composed of obligate endoparasitoid flies that attack heteropteran insects, many of which are important agricultural pests. To lay a foundation for future studies in phasiine life history and their potential for use as biological control agents, the phylogenetic relationships within Phasiinae were explored using nucleotide sequences of two genes, CAD and LGL. A total of 63 taxa for CAD and 73 taxa for LGL were included in the analyses, representing 58 genera. Maximum likelihood inference methods were employed to reconstruct phylogenetic relationships in separate analyses of each gene and in a combined dataset. Phylogenetic reconstructions generally supported recent morphological classifications based on oviposition strategies and postabdomen characters. All tribes in Phasiinae were recovered as monophyletic or could become so with minor changes to current classification schemes. Tachinidae was recovered as a monophyletic family, and the monophyly of the subfamilies Tachininae, Exoristinae, and Phasiinae was resolved with varying levels of statistical support. Dexiinae was paraphyletic. Significant results include the following proposed taxonomic revisions: 1) Removing
Litophasia from Catharosiini, 2) Transferring
Euclytia,
Eliozeta,
Ectophasia, and
Clytiomya from Phasiini to Gymnosomatini, 3) Including
Strongygaster and
Rondaniooestrus in Phasiinae, 4) Placing
Rondaniooestrus and
Opesia in Strongygastrini, 5) Creating a new tribe for
Xysta: Xystiini, 6) Placing
Hermya at the base of Strongygastrini in its own tribe Hermyini rather than in Cylindromyiini, and 7) Including
Litophasia,
Euthera, and
Epigrimyia in Dexiinae.

▼ This research presents the results of collaborative work with Sharon A. Jansa and Robert S. Voss on the systematics of the American marsupials of the genus Marmosops. Chapter 1 evaluates the species-level diversity of this genus using mitochondrial sequences from >200 specimens, including exemplars of every currently recognized species together with a dense intraspecific sampling. These data are analyzed using the General Mixed Yule Coalescent (GMYC) model and the results suggest that the genus could be twice as speciose as currently recognized. Additionally, the phylogenetic relationships within Marmosops are evaluated using sequences of the Breast Cancer Type 1 susceptibility gene (BRCA1). These analyses reveal a basal dichotomy between two ancient, morphologically diagnosable clades. Based on the latter results, a taxonomic proposal is made with the description of a new subgenus, Sciophanes. Chapter 2 includes a revision of the species of subgenus Sciophanes in the context of the molecular analyses of Chapter 1. This revision recognizes 12 valid species in three monophyletic species groups: the Parvidens Group (including M. pakaraimae, M. parvidens, and M. pinheiroi), the Fuscatus Group (M. carri, M. fuscatus, M. handleyi, and M. invictus), and the Bishopi Group (M. bishopi, M. juninensis, M. ojastii, and two new species). For each species, information about type material, ecogeographic distribution, and diagnostic morphological characters is presented. Chapter 3 evaluates the phylogenetic relationships of the tribe Thylamyini by using a multi-locus dataset. In particular, this chapter aims to resolve evolutionary relationships of the thylamyine genus Chacodelphys. A previous understanding of the species-level diversity within Marmosops is crucial for constructing a phylogeny of Thyamyini because this genus accounts for almost 45% of the diversity within the tribe. Phylogenetic analyses of these data convincingly resolves Chacodelphys as the sister taxon of Cryptonanus and supports most of the previous phylogenetic arrangements obtained within Marmosops.

▼ Species are the currency of biodiversity and an accurate recognition of their status is a scientific necessity, particularly given the onset of the Anthropocene (the most recent biodiversity crisis). Yet, concept-based species approaches are contentious whereas those more deterministic work against the fluidity of speciation itself. This conceptual gap can be bridged through a comprehensive assessment of the nine subspecies comprising the historically enigmatic Western Rattlesnake (Crotalus viridis) complex, one that employs three disparate datasets. First, mitochondrial DNA (mtDNA) sequence data were used to derive a Bayesian phylogenetic hypothesis that revealed two well- supported lineages, each with subspecies as distinct clades. Second, morphological data relating to head shape were analyzed using Geometric Morphometric (GM) methodology to again reveal two distinct lineages, each composed of subspecies that differ significantly in shape, yet with confounding factors that obscure evolutionary relationships. Finally, GIS-based macroecological variables gathered from museum specimens again demonstrated significant subspecific niches, suggesting the potential for ecological speciation within the complex. The three datasets (
molecular, morphological, and ecological) were coalesced using supertree methodology to derive a single hypothesis that supported two distinct lineages but with obscured subspecific relationships. They were also utilized in crosshair classification tests that quantified ‘historical’ and ‘recent’ non-exchangeability among lineages and subspecies (i.e., if these entities were distinct amongst themselves and worthy of taxonomic recognition). In this regard, sufficient genetic, ecological and morphological non-exchangeability exists between lineages and among subspecies to warrant species designations for six of 9 Western Rattlesnake subspecies, with the remaining three retained at subspecific status. These efforts thus represent a comprehensive and contemporary perspective of Western Rattlesnake biodiversity, and shed light on a group that has proven elusive across two centuries of scientific inquiry.

▼ This thesis is divided into two parts centred around the higher relationships of Micropezinae
(Diptera: Micropezidae). The first chapter is a multi-gene
molecular phylogenetic analysis of
Nerioidea (Diptera: Schizophora). The relationships of the four families of Nerioidea (Micropezidae,
Neriidae, Pseudopomyzidae, and Cypselosomatidae), as well as the internal relationships and
subfamilial classification of Micropezidae, have been the source of considerable debate. These
relationships are tested using 13 genetic loci sampled for 77 Nerioidea species and 39 outgroup
taxa from across Schizophora and analyzed using Bayesian Inference and Maximum Likelihood.
Nerioidea was recovered as monophyletic with strong support, as were each of the four families
within, with Micropezidae being returned as the sister group to the remaining Nerioidea. Internal
relationships of Micropezidae included strong support for each of the subfamilies with the
exception of Eurybatinae, which was recovered as polyphyletic, with the Metopochetini forming
a well-supported sister group relationship with Micropezinae. The remaining Eurybatinae were
well-supported as the sister group to Taeniapterinae. The implications for the
taxonomy and
classification of Micropezidae subfamilies are addressed. The tribe Metopochetini is elevated to
subfamily rank (Metopochetinae).
The second chapter of this thesis aims to clarify the higher relationships of Nerioidea within Schizophora. The relationships between superfamilies of Schizophora have proven difficult to establish on the basis of morphology and
molecular data to date, resulting in unstable classifications and evolutionary hypotheses. Using a supermatrix composed of previously published DNA sequences from 23 genetic loci sampled across 2300 schizophoran taxa, the relationships of Schizophora are estimated using Maximum Likelihood with multiple data subsampling and substitution model strategies. Two preferred trees were recovered which are strongly congruent with both morphological and genomic approaches, signifying supermatrix analyses represent a viable alternative for elucidating schizophoran relationships. Taxon availability and sampling, particularly among Carnoidea and Sphaeroceroidea, remain a significant barrier to a fully resolved phylogeny of Schizophora. Higher relationships of Schizophora were found to be highly sensitive to taxon sampling and substitution model parameters, while there is significant evidence of differential phylogenetic signal between nucleotide sites and taxonomic lineages, indicative of heterotachy. Implications for the future of Schizophora systematics are discussed.

▼ Tiksikseened (Helotiales sensu auct., Leotiomycetes, Ascomycota) kujutavad endast ˂2 mm läbimõõduga erivärviliste kausjas-peekerjate viljakehadega seeni. Nad on eluviisilt saproobid, parasiidid või sümbiondid (endofüüdid, mükoriisaseened) erinevatel taimedel, aga ka mullas ja vees. Olles küll looduses sagedased organismid, on neid keeruline määrata, sest morfoloogilised kriteeriumid on ebaselged ja molekulaarseks määramiseks napib DNA referentsjärjestusi. Doktoritöö põhieesmärk oli panustada fülogeneesipõhise klassifikatsiooni loomisse selles väheuuritud seenerühmas. Fülogeneesi rekonstrueerimiseks sekveneeriti mitmeid geenilõike. Lisaks uuriti võrdlevalt valitud taksonite morfoloogiat, kaasates transmissioon-elektronmikroskoopia meetodeid. Tulemusena selgus, et monofüleetilised rühmad eristuvad üksteisest mitmete tunnuste kombinatsiooni, mitte üksikute tunnuste poolest, nagu eoskoti tipustruktuur. Viimastele ei peaks andma võtmetähendust, kuivõrd konvergents on selles seenerühmas laialt levinud. Heaks näiteks homoplaasia kohta on jahukirmelise vintske viljakeha välisilme alusel eristatud perekond Encoelia, mis fülogeneesi põhjal osutus polüfüleetiliseks. Kaheksa Encoelia liiki lahknesid fülogeneesipuul kuude sugukonda, kusjuures perekonna tüüpliigiga ei olnud suguluses ükski teine Encoelia liik. Fülogeneesipõhise klassifikatsiooni loomisel taaselustati kaks ajaloolist sugukonda, kirjeldati uusi perekondi ja liike ning avaldati taksonoomilised rekombinatsioonid. Multigeen-fülogeneesipuu klaadid eristusid enamasti ökoloogia poolest.

The ultrastructure of apothecial hairs in the family Lachnaceae varies at the genus level, but the type of ascus apical apparatus of this family was the same except for Lachnellula. Phylogenetic analyses revealed historical characters such as the mealy appearance of apothecia and xero-tolerance to be homoplasious and the genus Encoelia to be polyphyletic with eight studied species distributed among six families.

▼ Membros do gênero Rhinebothroides são parasitas exclusivos de potamotrigonídeos, elasmobrânquios de água doce endêmicos da região Neotropical. Atualmente, seis espécies são reconhecidas para este gênero dentre as oito espécies nominais disponíveis. A taxonomia de Rhinebothroides é convoluta, pois a maioria de suas espécies são diagnosticadas por caracteres morfométricos e merísticos definidos por estudos que desconsideram a variabilidade intraespecífica destas linhagens. A ampla distribuição de algumas espécies, bem como seus padrões generalistas de especificidade padrão este discrepante em relação à tetrafilídeos marinhos sugere a existência de complexos de espécies que requerem melhor refinamento taxonômico. Este estudo visa refinar a taxonomia de um destes complexos Rhinebothroides freitasi, no qual estão inseridas outras 3 especies nominais (R. campbelli, R. circularisi, R. venezuelensis) cujas circunscrições são ambíguas. Neste estudo, partiuse da premissa de que a conjunção de dados moleculares e morfológicos pode elucidar a taxonomia deste complexo. Com este objetivo, dados moleculares para os genes 28S, ITS1 e COI foram compilados para 57 haplótipos de Rhinebothroides representando todas as espécies válidas para o gênero e a ampla distribuição biogeográfica no gênero nas bacias hidrográficas brasileiras. A otimização direta das sequências nucleotídicas destes haplótipos concatenadas com outros 26 terminais que incluem linhagens de tetrafilídeos marinhos e de água doce, resultou em cinco clados de Rhinebothroides que possuem morfologia congruente com a série tipo de cinco espécies nominais. Desta forma, este estudo reconhece cinco espécies de Rhinebothroides como válidas: R. glandularis, R. freitasi, R. moralarai, R. scorzai e R. venezuelensis. Dentre as espécies do complexo R. freitasi, os dados morfológicos compilados para ~ 400 indivíduos permitiu delimitar os níveis de variabilidade morfológica de R. freitasi e R. venezuelensis. A representatividade biogeográfica e de hospedeiros contemplada neste estudo revela que, ao contrário das linhagens de tetrafilídeos marinhos, membros de Rhinebothroides possuem baixa especificidade aos seus hospedeiros.
Members of Rhinebothroides are parasites of the Neotropical freshwater stingrays of the family Potamotrygonidae. To date, six species are recognized for the genus within which there are eight nominal species available. The taxonomy of Rhinebothroides is confusing, since most of its species are currently diagnosed by morphometric and meristic characters that have been defined by studies that disregarded the intraspecific variability of its lineages. The widespread distribution of some species, as well as their relaxed host specificity pattern which differs from what has been documented for marine tetraphyllideans suggests the existence of species complexes that require taxonomic refinement. This study aims at refining the taxonomy of one of these complexes Rhinebothroides freitasi, in which are included other three nominal species (R. campbelli, R.…

▼ Considerando-se a semelhança morfológica e ocorrência simpátrica de Anastrepha striata Schiner e Anastrepha bistrigata Bezzi, este trabalho propôs identificar formas para melhor caracterizá-las através de análises morfométricas do acúleo e asas de populações simpátricas e alopátricas dessas espécies, e molecular, por meio da análise de seqüências parciais do gene da citocromo oxidase I (COI). O trabalho também teve por objetivo desenvolver iniciadores espécie-específicos que possam vir a ser utilizados em estudos ecológicos em regiões em que ambas as espécies ocorram simpatricamente. As populações analisadas A. striata (seis populações) e A. bistrigata (duas populações) foram provenientes de diferentes regiões do Brasil, Colômbia e Bolívia. Para os estudos morfométricos, os acúleos e asas foram montados em lâminas para captura e análise de imagens com auxílio de câmera fotográfica acoplada ao microscópio estereoscópico, utilizando-se de software apropriado. Foram traçados e mensurados oito segmentos no acúleo e 16 na asa direita de cada indivíduo, obtendo-se assim as medidas nas quais se basearam as análises. Nos estudos moleculares, os produtos de amplificação obtidos para a COI foram seqüenciados e analisados para o estudo da caracterização molecular das diferentes populações desses insetos e desenvolvimento de iniciadores espécie-específicos. Os resultados indicam a existência clara de distinção morfométrica entre as duas espécies e confirmaram as identificações baseadas na largura e comprimento do acúleo. Os dados morfométricos mostraram também a ausência de padrões geográficos distintos entre as populações de A. striata e A. bistrigata. A. striata apresentou maior variação morfométrica entre suas populações quando comparada à diferenciação encontrada para A.bistrigata. Nas duas espécies, populações encontradas em maiores altitudes apresentaram maiores dimensões. A análise de nucleotídeos da seqüência da COI obtida para as populações de A. striata em questão indicou a ocorrência de alta similaridade entre as mesmas. As análises realizadas também indicaram que a divergência genética encontrada no fragmento da COI analisado para as diferentes populações de A. striata não permitiu o agrupamento de acordo com a distribuição geográfica dessas populações. A análise do fragmento do gene da COI permitiu o desenvolvimento de iniciadores com divergência suficiente entre as espécies em questão para permitir a amplificação de porção específica do gene da COI, que possibilita a diferenciação entre as mesmas. Os iniciadores propostos reúnem características que permitem a sua utilização em reações de PCR multiplex para a diferenciação entre espécimes de ambas as espécies.
Because of the fact that Anastrepha striata Schiner and Anastrepha bistrigata Bezzi are very similar morphologically and may also occur sympatrically, this study aimed to propose different ways to characterize them by using wing and aculeus morphometry, and mitochondrial DNA sequencing. This work also aimed to develop species-specific primers to allow for…

▼ The impact of environmental gradients on morphology has been an important topic in ecology and evolutionary biology, as geographic variation in environmental conditions may be a major factor involved in diversification. As such, phenotypic gradients (clines) associated with environmental gradients are worth investigating and understanding in greater detail. The Neotropical tribe Dorynotini Monrós and Viana, 1949 is a monophyletic group of tortoise beetles distributed from central Mexico to northern Argentina. Members are morphologically characterized by possessing an elytral suture that is distinctly adorned with a tubercle or a narrow vertical spiniform post-scutrellar projection. This spine exhibits a latitudinal gradient of continuous increase in height and decrease in width towards south of the tribe’s range. This cline provides initial evidence for geographic radiation, and grounds to investigate the interaction of climatic factors associated with the geographic complexity within the clade’s distribution, which may be the potential drivers to the group’s morphological and ecological diversity. Here, I reconstruct the evolutionary history of Dorynotini and seek the mechanisms driving the morphological heterogeneity contemplated by the group. The steps towards this goal included (Chapter 1, 2, 3 and 4) complete a species-level taxonomic revision of the tribe, to allow derive decisions about species delimitation; patterns of species distribution, morphology and ecology; (Chapter 5) test the monophyly of the tribe and its genera by combining morphological and
molecular data, to elucidate biogeographical patterns, and investigate the homology and evolution of the elytral post-scutellar projection and other key characters using ancestral character state reconstruction; and finally (Chapter 6), I explore the evidence behind the apparent cline by testing associations between climate and morphology across the clade’s distribution using an approach based on ecological niche modeling and morphological and environmental hypervolumes.

▼ Cette thèse porte sur la taxonomie des acariens prédateurs de la famille des Phytoseiidae, dont certaines espèces sont utilisées en lutte biologique pour contrôler des acariens ravageurs et quelques petites espèces d’insectes. La taxonomie de ces organismes de petite taille (<500 μm), i.e. identification spécifique et relations entre les taxa, est essentiellement basée sur des caractères morphologiques. Ces caractères parfois difficiles à visualiser, à interpréter (variations intra et inter-taxa, analogies) et en faible nombre rendent l’identification des espèces et la classification actuelle sujette à certaines interrogations ; aucune analyse phylogénétique ne soutient en effet la taxonomie de cette famille. De plus les marqueurs moléculaires développés jusqu’à aujourd’hui ne permettent pas de définir de façon fiable les relations entre les taxa supraspécifiques. Ce travail présente deux objectifs: (i) caractériser via des outils moléculaires l’identité spécifique de deux taxa utiles en lutte biologique et établir des règles de décision moléculaire sur la base de plusieurs concepts analytiques et (ii) déterminer via le développement de nouveaux marqueurs moléculaires les relations supraspécifiques à l’intérieur de la tribu des Euseiini puis au niveau de l’ensemble de la famille. Concernant le diagnostic spécifique, ce travail a montré à travers l’exemple d’Amblyseius swirskii et Phytoseius finitimus l’utilité d’approches intégratives comprenant plusieurs marqueurs, du fait de la forte variation des marqueurs mitochondriaux au niveau intraspécifique. Les valeurs maximales des distances génétiques entre spécimens d’une même espèce (9%, 23% et 2.8 % pour 12S ARNr, CYTB ADN mt et ITSS) ont été établies. Concernant les relations supraspécifiques, des nouveaux marqueurs moléculaires ont été développés. La combinaison de six marqueurs moléculaires (12S ARNr, CYTB ADN mt, COI ADN mt, ITSS, 28S ARNr, HSP90) permet désormais de résoudre les différents rangs taxonomiques à investiguer. L’application de ces marqueurs à la tribu des Euseiini et à l’ensemble de la famille a permis de conclure quant à la validité de certains taxa. Par exemple, ce travail a montré la monophylie des Euseiini et des représentants des sous- tribus considérés. Le genre Iphiseius ne semble en revanche pas valide et inclus dans le genre Euseius. Des analyses morphologiques, biogéographiques et écologiques (plantes-hôtes) réalisées au niveau de l’ensemble de la tribu sur la base d’une compilation bibliographique, ont permis d’émettre des scénarios quant à l’origine ouest gondwanienne de ce taxon sur des plantes de Rosidées et quant à l’évolution de certains caractères morphologiques.Ce travail de thèse ouvre des perspectives d’étude des relations entre les genres de Phytoseiidae du fait des nouveaux marqueurs développés. Les études doivent se poursuivre pour (i) étendre le panel de marqueurs disponibles et surtout (ii) augmenter l’échantillonnage des espèces à inclure dans les analyses en lien avec leurs caractéristiques bioécologiques afin de déterminer…

▼ Tillandsia L. is the largest genus of the subfamily Tillandsioideae (Bromeliaceae) with ca. 557 species. It is distributed from the southern U. S. A to central Argentina and Chile. Traditionally the genus has been divided into seven subgenera: Tillandsia subg. Allardtia (A. Dietrich) Baker, Tillandsia subg. Anoplophytum (Beer) Baker, Tillandsia subg. Phytarrhiza (Vis.) Baker, Tillandsia subg. Diaphoranthema (Beer) Baker, Tillandsia subg. Tillandsia L., Tillandsia subg. Pseudalcantarea Mez and Tillandsia subg. Pseudo-Catopsis Baker. The taxonomic study of the species Tillandsia in the Paraná state was presented. Were found 17 species in 4 subgenera:Tillandsia subg. Diaphoranthema -Tillandsia loliacea Mart. ex Schult. &Schult.f., Tillandsia recurvata (L.) L, Tillandsia tricholepis Baker and Tillandsia usneoides (L.) L.; Tillandsia subg.

Identification Keys, as well as descriptions, illustrations, comments and distribuition patterns are presented. The results show that the Paraná has a high species richness when compared to neighboring states. Besides the taxonomic study, there were some evolutionary adaptations of species, fitting them in ecophysiological types proposed in the literature. Only T. polystachia presents wide rosette forming tank. The remaining species are characterized by the absence of the tank, the presence or absence of non-root in adulthood and four species were found to be minimized.
Tillandsia L. é o maior gênero da subfamília Tillandsioideae (Bromeliaceae) com 557 espécies, distribuídas desde o sul dos Estados Unidos até a Argentina e o Chile.

▼ Bromeliaceae é essencialmente neotropical, atualmente com 58 gêneros e aproximadamente 3.172 espécies, sendo o Brasil, seu maior centro de diversidade, com aproximadamente 43 gêneros (17 endêmicos) e 1.200 espécies ocorrendo em todos os biomas, sendo a maior riqueza específica, localizada na costa leste, na Floresta Atlântica. Aspectos evolutivos como a captação e o armazenamento de água pelas folhas dispostas em roseta, formando um tanque, e a absorção de água e nutrientes através dos tricomas, possibilitaram a vida em ambientes diversos e extremos, contribuindo para a ampla distribuição desta família, além de gerar condições necessárias para a sobrevivência de muitos organismos entre suas folhas. A família está subdividida em oito subfamílias: Brocchinioideae Givinish, Lindmanioideae Givinish, Tillandsioideae (Dumortier) Harms, Hechtioideae Givinish, Navioideae Hams, Pitcairnioideae (Meisner) Harms, Puyoideae Givinish e Bromelioideae. O gênero Vriesea Lindl. pertence a subfamília Tillandsioideae, com 261 espécies, distribuídas predominantemente na América do Sul. Este gênero possui grupos de espécies, de difícil delimitação, entre eles, o complexo Vriesea platynema Gaudich. com 41 espécies. Este, ocorre desde a América Central até a Argentina, com um acentuado polimorfismo, propiciando a identificação errônea dos táxons. Baseado em material in vivo e em coleções de herbários, um estudo taxonômico foi realizado no Estado do Paraná. Foram reconhecidos três táxons: Vriesea platynema Gaudich. var. platynema, táxon amplamente distribuído classificado como não ameaçado (LC) de acordo com os critérios estabelecidos pelo IUCN, Vriesea platynema var. variegata (Guillon) Reitz, endêmica para o Paraná e classificada em perigo (EN), devido a extensão de ocorrência reduzida, e Vriesea tijucana E. Pereira, enquadrada como em perigo (EN), por ser restrita a Floresta Ombrofila Densa em terras baixas e apresentar poucos pontos de ocorrência, sendo estes localizados em áreas de proteção ambiental ou áreas urbanas em desenvolvimento. Para cada táxon, são apresentadas descrições, comentários, chave de identificação, distribuição geográfica, ilustrações e o status de conservação. Paralelamente, um estudo anatômico dos órgãos vegetativos foi realizado, onde procurou-se identificar características anatômicas com valor taxonômico, além de verificar as adaptações ao hábitat de cada táxon. Os três táxons analisados apresentam raízes absortivas e grampiformes, com tanque bem desenvolvido e tricomas especializados, metabolismo principalmente C3 e hábito epifítico.
Bromeliaceae Juss. is essentially neotropical, represented by 58 genera and about 3.172 species, being Brazil its largest center of diversity, with 42 genera, 17 are endemics, and 1.200 species, occurring in all biomes, with the highest species richness locates on the coast east, the Atlantic Forest. Evolutionary aspects as the capture and storage of water by leaves arranged in a rosette, forming a tank, and the absorption of water and nutrients through the trichomes, possible…

▼ Algae are a diverse assemblage of photosynthetic organisms that includes prokaryotes (Cyanobacteria) as well as unicellular and multicellular eukaryotes. They inhabit freshwater, saltwater, and terrestrial ecosystems. Terrestrial algae include microscopic photobionts that thrive (both in abundance and diversity) in humid conditions. Unfortunately, terrestrial algae are an understudied group in the field of biology. This dissertation presents algal systematic research from the neotropical rainforests of Panama (Central America) and Suriname (South America) as well as coastal areas of Oahu, Hawaii (USA). Finally, an overall phylogeny of all green algae is inferred through multigene
molecular phylogenetic inference. Biodiversity assessments were based on environmental cloning and sequencing. Systematic biology techniques included morphological observations via light and electron microscopy from specimens isolated through unialgal culture. Systematic assessments were further confirmed through
molecular phylogenetic trees reconstructed by Bayesian inference, maximum likelihood, and parsimony methods. Environmental sequencing results suggest that the Surinamese rainforest Raleighvallen is comprised of various green algal (Chlorophyta), nostocalean (Cyanobacteria), and diatom (Heterokontophyta) taxa.
Molecular phylogenetic analyses of the green algal order Trentepohliales collected from Panama strongly suggest that the genera Printzina and Trentepohlia do not form separate monophyletic lineages. These results indicate that the morphological characteristics currently used to distinguish these two genera need to be reassessed. The green alga Spongiochyris hawaiiensis is a common epiphyte found on the bark of Casuarina trees in Waimanalo state park on the island of Oahu.
Molecular phylogenetic analyses as well as electron microscopy observations of this alga strongly suggest that it belongs to the order Cladophorales. Finally, a multigene phylogeny of green algae from all habitats (marine, freshwater, and terrestrial) was inferred from GenBank and unpublished sequences. Within the division Chlorophyta, the classes Chlorophyceae, Trebouxiophyceae, and Ulvophyceae formed separate monophyletic or natural assemblages. Furthermore, this phylogeny strongly suggests that there were multiple migration events from aquatic environments (from both fresh and marine waters) to land within the Chlorophytan algae.

The role of intraspecific diversity in coral-algal symbiosis

▼ Coral-algal mutualisms, the foundation of reef
ecosystems, can break down during periods of thermal stress. The
extent to which such partnerships may acclimate or evolve to
survive a changing climate is poorly understood. Though
evolutionary responses are driven by the natural selection of
functional variation among individuals within species, such
variation has been difficult to quantify in coral systems. Here, I
use high-resolution molecular techniques to differentiate
individuals, populations, and species within coral symbioses and
subsequently quantify the ecological and evolutionary relevance of
intraspecific variation. In the first chapter, I review the
technological advances that have made such work possible, and
describe preliminary data from several researchers indicating that
intraspecific variation may be extensive among coral hosts and
symbionts. In the second chapter, I test the value of manipulating
coral-algal partnerships during host larval development for
restoration purposes, finding little influence of symbiont identity
on growth rates during early ontogeny. In the third chapter, I
formally describe several new species of Symbiodinium, the
morphologically cryptic dinoflagellate endosymbionts that associate
with cnidarians, and draw attention to the ecological diversity
that can be found even among closely-related groups. In the fourth
chapter, I characterize molecular variation among individuals of
the coral Acropora palmata that affects the photochemistry of a
clonal symbiont responding to thermal stress, emphasizing that fine
scale partner interactions can yield functional variation among
coral holobionts with potential evolutionary consequences. In the
fifth chapter, I compare gene content and steady-state expression
among several closely related Symbiodinium within the Clade B
lineage, identifying phylogenetic and ecological transcriptional
signatures among species. This work represents a few first steps
into the complex and exciting territory of fine scale variation
among marine mutualisms.
