Species of the fraterculus group are associated to the biggest damages to fruit crops due to the fact that they attack indiscriminately green and ripe fruits, making them pests of great economic importance. These species are hard to tell apart, even showing some potential criptic species. The understanding of the populational structure and biology of this species group is of paramount importance to strategies of management and control of these pests. Here, we investigate variation on the gene yolk em 37 individuals sampled throughout the species distribution in Brazil seeking to better understand the populational structure of this species group in Brazil. Our data indicated existence of recombination, which lead us to analyze three different regions in the gene, 5, mid, and 3. These regions show high levels of nucleotide diversity intra and interspecifically for all three gene regions investigated. The use of Nested Clade Phylogenetic Analysis independently used on these regions indicate two main results that occurred more than one throughout our analyses. The first is a range expansion from north-NE populations towards the south, mostly related to specimens of Anastrepha fraterculus. The second common event, detected eight times, is restricted gene flow with isolation by distance (IBD). Dating of such events indicated that they are temporarily congruent which might indicate that the lack of IBD in other levels of the analysis might be caused either by sampling limitations or an excess of local gene flow that tampers out as we move farther in space. Our results of the gene yolk have provided us with a better understanding of the levels of local variation of this marker of for the species that may help us determine the evolutionary processes that shaped the species group current distribution.

Espécies do grupo fraterculus estão relacionadas com os maiores danos a culturas de frutas carnosas por atacar frutos verdes e maduros indistintamente, o que as torna pragas de grande importância econômica. Contudo, estas espécies são de difícil distinção, com a existência potencial de diversas espécies crípticas. Dessa forma, o entendimento da biologia e, particularmente, da estrutura populacional desses insetos-praga tem grande importância para o desenvolvimento de novas estratégias de manejo. Neste trabalho, investigamos a variação no gene yolk em 37 indivíduos ao longo da distribuição do grupo no Brasil para conhecermos melhor o padrão estrutural das espécies do grupo fraterculus. Os dados indicam a existência de recombinação, de forma que analisamos a região amplificada separadamente por regiões distintas: 5, mid e 3. Análises de polimorfismos nestas regiões apontaram para altos valores de diversidade nucleotídicas intra e interespecíficas para as três regiões gênicas em questão, sendo estes valores maiores para a região 3. A metodologia da Análise dos Clados Aninhados (NCPA) foi utilizada para inferências de possíveis relações entre a configuração das redes haplotípicas com o padrão de distribuição geográfica…

▼ Pine cone beetles (Conophthorus sp.) are serious pests of many forest ecosystems since they burrow into pine cone tissues for egg deposition, causing the death of the seeds. Management of these beetles in natural and commercial stands of pines has been problematic due to lack of understanding about species limits and distribution. This study was conducted to investigate the phylogeography and phylogenetics of the genus. Several species represented by disjunct populations appear to be monophyletic including Conophthorus edulis, C. mexicanus, C. coniperda, and C. conicollens, whereas C. ponderosae is polyphyletic with many distinct clades isolated by geography. This study explored whether host use or geography has played a greater role in the diversification of this genus, focusing on the polyphyletic C. ponderosae and the monophyletic C. edulis. In the first study, 751bp of the mtDNA CO1 gene were sequenced to reconstruct a phylogeny of the genus, and the distribution and host use were compared to investigate whether these factors were significantly associated. The second study addressed population structure and possible historical influences on the C. edulis and C. ponderosae populations using a nested clade analysis of the mtDNA haplotypes. Despite potential limitations due to sampling, several conclusions could be drawn. Three separate haplotype networks were found for the C. ponderosae haplotypes, indicating that there have been at least three lineages that have associated with P. ponderosa. Geography was significantly associated with the phylogeny at greater distances (>900km), but host use was not significant. At the species level, association with geography is variable. Population structure for C. ponderosae at the species level is minimal, and suggests that there has not been much time for lineage sorting of the haplotypes based on the nested clade analysis as compared to C. edulis.

▼ Species distributions and population genetic structure are determined by landscape history and biological characteristics of an organism. Pleistocene glaciations affected species distributions and freshwater drainage patterns. Extensive work on the biogeography of fish has determined the effects of glaciations on genetic population structure and described recolonization routes from glacial refugia. Freshwater mussels are intimately tied to fish because larvae are largely obligate parasites on fish. Dispersal via hosts has likely led to similar patterns in genetic structure and distributions of mussels and fish. I quantified genetic diversity using mitochondrial DNA and allozymes to determine genetic population structure and infer evolutionary history for Cumberlandia monodonta an endangered species (Chapter 2). There was a lack of genetic structure and evidence of high gene flow. The phylogeny indicated isolation in two glacial refugia followed by post-Pleistocene dispersal of two lineages range-wide. The distribution of Lampsilis cardium, a non-endangered species, spans glaciated and non-glaciated areas. Genetic diversity was quantified in northern and southern populations to determine if this large-river species has similar patterns found in other species of fish and mussels (Chapter 3). Genetic data from populations in the upper midwest and Canadian drainages were used to test hypotheses of dispersal from the upper Mississippi River (UMR) into the Red River of the north (RRN). Overall genetic diversity was high, but populations in the north and south had similar levels. There was evidence for two glacial refugia in the Great Lakes basin, but not the upper midwest. Genetic data did not support the hypothesis of post-Pleistocene dispersal from the UMR into the RRN. On a smaller spatial scale, genetic variation and structure of L. cardium from the UMR was also quantified with microsatellite markers (Chapter 4). The UMR is fragmented with locks and dams creating distinct river reaches, therefore, population genetic variation and structure were measured within a spatial hierarchy. Historic and contemporary gene flow were compared to determine if the dams are affecting genetic diversity. Genetic diversity was high, and populations in the UMR may be panmictic. There is evidence that fragmentation may be reducing gene flow for this species. Advisors/Committee Members: Berg, David (Committee Chair).

▼ Whether active or passive, dispersal accompanied by gene flow shapes the population genetics and evolutionary divergence of species. Indirect methods which use genetic markers have the ability to assess effective dispersal—that which resulted in gene flow. My objective was to see if an aquatic insect and an obligate aquatic invertebrate show similar phylogeographic patterns and genetic uniqueness. Hyalella azteca and Callibaetis americanus were collected from 4-5 springs in each of six basins in the Great Basin of western North America. No dispersal or genetic studies of C. americanus have been conducted to date. However, several studies focusing on mtDNA diversity of H. azteca have revealed a tremendous degree of cryptic diversity in the desert springs of the Great Basin. Nested clade phylogeographical analysis (NCPA), FST values, AMOVA, and Mantel tests were used to examine geographical associations. I also used traditional phylogenetic approaches including maximum parsimony (MP) and likelihood (ML) analyses using cytochrome c oxidase subunit I (COI), 28S, and 16S as genetic markers. The mitochondrial COI sequence divergences in C. americanus were higher than H. azteca COI divergences within springs but lower among springs. FST values were very high in H. azteca reaching near fixation for certain alleles. C. americanus FST values were lower suggesting greater gene flow and, consequently, greater dispersal rates. Even though Mantel tests did not detect significant isolation by distance when evaluating all haplotypes together, nested clade analysis was able to examine smaller networks of related haplotypes and detect significant isolation by distance. Whereas the genetic structure in C. americanus was dominated by restricted gene flow with isolation by distance, H. azteca was characterized more by gradual range expansion followed by fragmentation. Mayflies likely showed more gene flow than amphipods because of their flight capabilities, but movement was still restricted by long distances between isolated springs.

▼ In this collection of papers I have summarized my investigations into the field of evolutionary genetics and more specifically into patterns of biodiversity and evolutionary processes. The lizards (and frogs) studied here share common features in that they are largely present in unique environments, which are also regions that are biologically understudied. Most of these taxa show high degrees of endemism, interesting natural history characteristics, and each group manifests distinctive adaptations of general evolutionary interest. My work in the genus Telmatobius has been a progressive approach that began in my MS program, and it first focused on alpha taxonomy, morphological variation, and species boundaries. This work led to new studies initiated and completed at BYU involving further taxonomic revision (Formas et al., 2003; Chapter 1), and then revisiting and re-evaluating species boundaries established earlier (with allozyme markers) and this time with population level molecular (mitochondrial DNA) markers (Chapter 2). Our results indicate that the striking differences in size, coloration and general appearance in the various Lake Titicaca morphotypes are not genetically based. Further, there is evidence that these morphotypes have evolved very rapidly after demographic bottlenecks eroded present genetic variability. Telmatobius frogs of Lake Titicaca are listed by the International (IUCN) as critically endangered. We support this classification and further suggest studies to explore open questions like the possibility of adaptation along ecological resource gradients. Lizards of the genus Microlophus are interesting but for different reasons, and studies of this group constitutes the bulk of my dissertation work. The genus includes both Galapagos insular species, and continental taxa distributed in a linear gradient along > 4000 km of the western coast of South America. In studying Microlophus I first tackled the unresolved phylogenetic relationships within the genus (Chapter 3) and then pay attention to phylogeographic aspects of the most speciose lizard radiation in the Galapagos Archipelago (Chapter 4). Chapter 3 is a single manuscript provisionally accepted in the journal Systematic Biology. This paper introduces the lizard genus Microlophus (“lava lizards”) as a study system, and includes a large nuclear data set accompanied by an equally large mitochondrial data set (7877 characters in total). This paper explicitly differentiates among sequence alignments of gene regions that vary in tempo and class of mutational events. We show that this recognition is important and we suggest ways to appropriately deal with the alignment of multi-locus non-coding DNA data sets. A secondary finding in this study is that mtDNA and nDNA topologies are discordant with each other but that both are strongly supported, and that the nuclear topology is concordant with species distribution patterns along coastal South America. We hypothesize that in this particular region of the tree, the nuclear genome recovers a topology…
