▼ The Fence Lizard (Sceloporus undulatus complex) is a wide ranging North American species complex occurring from the eastern seaboard westward through the great plains and central Rocky Mountains and into the American Southwest. A recent phylogeny suggests four species lineages occur within S. undulatus. Traits within an interbreeding species that are influenced by sexual selection are under different selection pressures and may evolve independently from the selective forces of habitat. Sceloporus lizards have several characters that are influenced by sexual selection. I investigated sexual size dimorphism and allometric relationships of body size (snout vent length), torso length, rear leg length and three measurements of head size in 12 populations from the four species in the S. undulatus complex (N=352) specifically looking for variation among the 4 species. Additionally I investigated the size of signal patches between males and females in three species (N=339 specimens of S. consobrinus, S. cowlesi, S. tristichus) of the S. undulatus complex. Sexual confusion, was recently described in a population of the Sceloporus undulatus complex occurring in White Sands, New Mexico and the behavior is correlated with variation in badge size between male and female lizards. To make inferences about sexual confusion at the species level I investigated the presence and absence of signal patches in female lizards, and compare the sizes of signal patches between males and females. My analyses suggest that torso length and head size are significant sources of sexual size dimorphism but the findings differ from earlier published investigations of sexually dimorphic characters in the species complex. I also find support for the S. undulatus complex being generally a female larger species complex. However two of the 12 populations I investigated displayed male biased sexual size dimorphism. Analysis of signal patches across three species of the S. undulatus complex suggests that sexual dimorphism in signal patch size for S. cowlesi and S. tristichus may not prevent sexual confusion. While the near total absence of signal patches in female S. consobrinus is evidence that sexual confusion is not possible with regards to signal patches. Advisors/Committee Members: Hibbitts, Toby J.

Growth to asymptote under different population densities in the female-biased sexually size dimorphic tarrkawarra (Notomys alexis) – 3. Litter sex-ratio effects on female but not male growth in a small mammal with female-biased sexual size dimorphism – 4. Can female mate-choice explain female-biased sexual size dimorphism in tarrkawarra (Notomys alexis)? – 5. Male mate choice in tarrkawarra (Notomys alexis), a mammal with significantly female-biased sexual size dimorphism – Conclusion.

Female-biased sexual size dimorphism (FSSD) is an unusual phenomenon in mammals, which are typically male-biased sexually size dimorphic (SSD). Mammalian FSSD is also poorly accounted for by theory and, in particular, by sexual selection theory (Chapter 1). In this thesis I demonstrate that tarrkawarra (Notomys alexis or spinifex hopping mouse), is an excellent model system with which to investigate mammalian FSSD for the following reasons: Firstly, captive tarrkawarra and some field populations demonstrate a high level of FSSD relative to other FSSD mammals. Secondly, sexual size parity in other tarrkawarra populations, implies intra-specific variation in the degree of FSSD expressed. Studies of intra-specific variation have some advantages over inter-specific studies. Thirdly, tarrkawarra are small, easy to maintain in captivity and common in their natural habitat (the Australian arid zone).

Based on the field data published, I determined that intra-specific variation in the degree of FSSD tracks the environmental fluctuations that increase tarrkawarra populations 40 to 100-fold between long ‘bust’ and short ‘boom’ periods (Chapter 2). Spatial distribution of resources and potential mates is usually a strong determinant of optimal mating system and flexibility in tarrkawarra social organisation therefore seems likely. Flexibility would also explain why attempts to categorise the mating system have never satisfactorily accounted for all observations of the animals’ reproductive physiology and behaviour.

To test the flexibility of FSSD in tarrkawarra, I assessed developmental and environmental effects on the degree of FSSD in a captive tarrkawarra population. I found evidence for divergent male and female growth from birth, mitigated by both population density (Chapter 2) and by neonatal litter composition (Chapter 3). Specifically, litter sex-ratio effects on female growth and reproductive success suggest sex differentiated maternal investment. Litters sired by larger males were also found to have a higher sex ratio, suggesting that, despite low inter-male competition, sexual selection may still be important in this species via mating preferences.

Studies of first female (Chapter 4), then male mate choice (Chapter 5) support there being a role for sexual selection in the mating system of tarrkawarra. Both sexes demonstrated large-partner preferences, although male preferences…

Thesis Ph. D. Michigan State University. Zoology - Ecology, Evolutionary Biology and Behavior - Dual major 2013.

My dissertation focuses on how maternal and ecological factors influence growth rate variation, the life history consequences of growth variation, and on the evolution and development of 'reversed' sexual size dimorphism (SSD) in spotted hyenas. My dissertation consists of four chapters following the introductory chapter. The first of these research chapters, Chapter 2, describes the ontogeny of morphological sexual dimorphism in spotted hyenas, and documents sex differences in rates of growth of overall both body size as well as growth rates of individual morphological traits. Chapter 3 documents the importance of litter size, intra-litter rank, maternal parity, prey availability, and maternal social rank on variation in growth rates and adult size, and the resulting life history and fitness consequences of variation in growth rates. Chapter 4 focuses on whether selection on overall body size or on specific components of body size is present among female hyenas using lifetime measures of fitness to identify putative evolutionary mechanisms maintaining the observed dimorphism. Finally, in Chapter 5 I address hypotheses for the role of selection in males and females as drivers of degree of sexual dimorphism. The hypotheses I test include that selection on size in males does not contribute to female-biased SSD, that smaller males have better reproductive success, and finally that both males and females have increased reproductive success with increasing size, but the fitness benefit of increasing size is greater for females. I also address the quantitative genetics of morphological traits by estimating heritability; non-zero heritability is necessary for an evolutionary response to the observed selection. In its entirety, my dissertation results are consistent with the hypothesis that the difference in selection estimates between males and females contributes to the maintenance of sexual size dimorphism in the spotted hyena. On the whole, the results of the analyses in my dissertation represents an important addition to our knowledge of morphology and life history in the spotted hyena, especially with respect to SSD. My dissertation also provides the first measures of selection using lifetime fitness in a large mammalian carnivore. Finally, my dissertation presents estimates of quantitative genetic parameters, which are rarely available for mammalian carnivores, or for large mammals in general.

▼ I describe the natural history and reproductive behaviours of the Emei Moustache Toad (Leptobrachium boringii), testing the hypotheses that the species exhibits resource defense polygyny, and that combat, and paternal care lead to the evolution of male-biased sexual size dimorphism. In this study I document combat behaviour and paternal care for the first time in this species. Between February and March of 2011 and 2012, 26 female and 55 male L. boringii from Mount Emei UNESCO World Heritage Site, Sichuan, China, were observed throughout the breeding season. Prior to the breeding season, males grow 10-16 keratinized maxillary spines, which fall off once the season has ended. Throughout this time, males construct and defend aquatic nests where they produce advertisement calls to attract females. In a natural setting, I documented 14 cases involving a total of 22 males where males used their moustaches for aggressive interaction, and nest take over was observed on seven occasions. Despite my predictions, neither male body size nor body condition significantly affects the outcome of an aggressive interaction, though this may be representative of a low sample size. Males were also observed to possess injuries resulting from combat. Combat trials conducted in artificial nests demonstrated heightened aggression from resident males towards intruders. Genetic analysis using microsatellite markers revealed several cases of multiple paternity, both within nest and within clutch, indicating that some alternative male reproductive strategy, such as satellite behaviour is occurring. Larger males were observed to mate more frequently, and in multiple nests, suggesting that females are selecting for larger males, or that larger males are more capable of defending high quality territories. Males showed evidence of paternal care behaviours by remaining with the nests once females had left, moving throughout the nest cleaning, touching the eggs, and blowing bubbles into the centre of the doughnut-shaped egg masses. From this study I conclude that the male biased sexual size dimorphism in L. boringii is likely the result of both combat and paternal care behaviours creating a selection pressure on male body size.

▼ The identification of biotic and abiotic factors that promote the diversification of clades across Africa and the Arabian Peninsula remains a difficult challenge. A variety of ecological and evolutionary processes can be driving such patterns, and clade-specific traits may also play a role in the evolution of these groups. Comparative evolutionary studies of particular clades, relying on a phylogenetic framework, can be used to investigate many of these topics. Beyond these mechanisms there are abiotic factors, such as geological events, that can drive vicariance and dispersal events for large sets of taxa. The investigation of historical biogeography in a comparative phylogenetic framework can be used to detect such patterns. My dissertation explores these topics using reptiles and amphibians as study systems, and I rely on the generation of molecular sequence data, phylogenetics, and the use of comparative phylogenetic methods to address a variety of questions. I provide the abstract for each chapter below.Chapter 1: The reproductive modes of anurans (frogs and toads) are the most diverse among all the terrestrial vertebrates, and a major challenge is identifying selective factors that promote the evolution or retention of reproductive modes across clades. Terrestrialized anuran breeding strategies, in which breeding is partially or completely independent of water, have evolved repeatedly from the plesiomorphic fully aquatic reproductive mode, a process which is thought to occur through a series of intermediate reproductive stages. A number of selective forces have been proposed for the evolution of terrestrialized reproductive traits, but factors such as water systems and co-evolution with particular ecomorphologies have not been investigated in a comparative phylogenetic framework. We examined these topics and the evolution of reproductive mode in Afrobatrachian frogs, an ecologically and reproductively diverse clade representing more than half of the total frog diversity found in Africa (~400 species). We find that direct development evolved twice independently from terrestrialized reproductive modes involving protected eggs or larvae, supporting the intermediate stages hypothesis. We detected correlated evolution in specific derived ecomorphologies and reproductive traits, including arboreality and arboreal oviposition, and fossoriality and subterranean oviposition. There is support for a link between lotic water systems and terrestrial oviposition, and between arboreal ecomorphology and the use of lentic water systems for reproduction. Our findings indicate clade-specific processes driving the evolution of reproductive modes in the Afrobatrachia, and suggest that other processes such as habitat filtering and co-evolution with ecomorphology may generate global patterns of anuran reproductive modes.Chapter 2: Custom sequence capture experiments are becoming an efficient approach for gathering large sets of orthologous markers with targeted levels of informativeness in non-model organisms. …

A biologia reprodutiva dos Amphisbaenia é uma das menos estudadas entre os répteis, havendo na literatura informações sobre o ciclo reprodutivo, dimorfismo sexual e fecundidade de poucas espécies do grupo, além de informações pontuais acerca de oviposturas. A histologia das vias genitais, da mesma forma, foi pouco estudada, tornando difícil uma melhor caracterização dos ciclos de machos e fêmeas. No Brasil são encontradas cerca de um terço das espécie do grupo, distribuídas por regiões com diferentes características macroclimáticas. Este trabalho teve por objetivo caracterizar o ciclo reprodutivo de machos e fêmeas de onze espécies brasileiras da família Amphisbaenidae, com base em dados de dissecção e histologia, e analisá-los comparativamente tendo como referência a filogenia molecular já proposta para as Amphisbaenidae do Brasil. Objetivou-se ainda realizar uma análise preliminar da relação entre os ciclos reprodutivos observados e variações sazonais de temperatura e precipitação. Para tanto, foram analisados espécimes depositados em coleções zoológicas, que tiveram suas gônadas e órgãos urogenitais examinados e medidos. Foram ainda realizadas análises histológicas de ovidutos, testículos, ductos deferentes e rins de espécimes coletados em diferentes meses do ano, para análise de sua morfologia e caracterização dos ciclos espermatogênico, de estocagem de esperma e de atividade do segmento sexual renal. Foram ainda analisados espécimes e lâminas histológicas de duas espécies da família Blanidae e uma da família Trogonophidae, permitindo uma melhor discussão das características observadas tendo como referência a filogenia do grupo. Foram analisados também dados de dimorfismo sexual de tamanho do corpo e de fecundidade. Os machos de quatro espécies de Amphisbaenidae amostradas apresentaram ciclos reprodutivos assazonais, com períodos de repouso não sincrônicos entre os indivíduos. Os machos de outras sete espécies de Amphisbaenia, duas de Blanidae e uma de Trogonophidae apresentaram ciclos sazonais. Todas as sete espécies para as quais o ciclo das fêmeas pôde ser caracterizado são sazonais nesse aspecto. Os ciclos de machos foram comparados quanto à época e duração das fases de espermatogênese, estocagem de esperma e atividade secretora do segmento sexual renal, tendo sido obtidas evidências de relação entre essas características e a filogenia do grupo. As fases reprodutivas das espécies de Amphisbaenia brasileiras são mais extensas em comparação com aquelas observadas em Blanidae e Trogonophidae. Também se obtiveram evidências preliminares da relação entre sazonalidade dos ciclos reprodutivos e variações anuais de temperatura e precipitação. Em sete espécies de Amphisbaenidae, foi observado dimorfismo sexual quanto ao comprimento rostro-cloacal ou ao comprimento da cauda. A fecundidade das fêmeas varia entre um e quatro ovos, na maioria das espécies analisadas, mas pode chegar a sete em Amphisbaena mertensi e nove em Amphisbaena trachura.

Antennal sexual dimorphism is common in insects and antennae of males are often more complex than those of females, due to sexual selection. In Aphidoletes aphidimyza, males have long plumose antennae while females have short antennae. However, the driving factors of this antennal sexual dimorphism are unknown. The hypothesis is that sexual dimorphism in A. aphidimyza mainly results from sexual selection, as longer and more symmetric antennae should improve access of males to a mate. Moreover, the size of wings should vary as antennae size and larger structures should be observed in larger males (isometry). First, the morphology of males of A. aphidimyza and its influence on the reproductive behaviour were studied. There are positive linear relations between antennae, wing and tibia sizes (the size of the tibia being used as a proxy of the body size) in males of A. aphidimyza. Moreover, males with long antennae relatively to their body size have a higher probability to access a mate than others. Secondly, the effects of developmental temperature on the morphology and on the reproductive behaviour of males of A. aphidimyza were investigated. Males that developed at lower temperature are larger, with larger antennae and wings, than males that developed at higher temperature. The antennae size presents a negative allometry while wing size presents a positive allometry according to the body size. However, these morphology differences do not seem to impact the mating success of males. In short, longer and more symmetric antennae do not improve the access of males to a mate, but a high antenna to tibia ratio does, which gives a partial answer to this questioning about factors that may cause and maintain sexual dimorphism in A. aphidimyza.

▼ ENGLISH ABSTRACT: PELOMEDUSA SUBRUFA is a freshwater turtle widely distributed throughout Africa and Madagascar, and is described as a Tropical to Sub-tropical species. 1 examined the female and male reproductive cycles of P. subrufa, over a 20-month period to determine whether they display a typical Tropical to Sub-tropical type reproductive cycle (pre-nuptial) or a typical Temperate Zone type reproductive cycle (post-nuptial). Blood and tissue samples were collected from wild specimens captured in the Western Cape, South Africa and these samples were supplemented by tissue samples obtained from museum specimens. In female P. subrufa seasonal variation in related circulating reproductive hormones in the plasma (estradiol, progesterone, and testosterone) were analyzed using validated ELISA kits. Plasma vitellogenin (yolk precursor produced in liver) was measured using a newly developed universal vitellogenin ELISA for vertebrates (UNIVTG). Ovarian follicles were measured (± 0.1 mm) and female ovaries were staged macroscopically (non-active, pre-vitellogenic, vitellogenic, gravid), and results were confirmed via histological sectioning of ovaries and oviducts. Females exhibited a cyclic reproductive pattern, with distinct phases of follicular enlargement (vitellogenesis), ovulation and a gravid period. Seasonal timing of the reproductive cycle coincided with those of other temperate zone freshwater turtles. Vitellogenic recrudescence began in summer (late December), and continued unabated through winter with ovulation occurring in the following spring (September-October). My data suggested that P. subrufa females mostly lay a single clutch of eggs during the late-spnng summer period (September through January). Clutch size varied between 7 -3 7 eggs, with the number of eggs being significantly correlated with maternal body size (r = 0.82, P < 0 001). Plasma estradiol and plasma vitellogenin concentrations peaked once during the ovarian cycle, typically coinciding with the period of early- to mid-vitellogenesis in late summer. Plasma testosterone varied throughout the year, but significant increases were measured during the ovulation and mating period in spring. Plasma progesterone concentrations were significantly elevated during the gestation period prior to ovi-position in mid-summer (December). In male P. subrufa spermatogenesis in mature specimens was distinctly seasonal and timing of the reproductive cycle coincided with those of other temperate zone freshwater turtles. Spermatogemc recrudescence began in summer, following emergence from a winter hibernation period (brumation) and spring mating. Peak testicular volume and maximum spermiogemc activity occurred in late summer and early autumn. Testicular regression commenced in autumn through winter. Spermatozoa were abundant in the ducti epididymi throughout the year. Plasma testosterone concentrations peaked once during the testicular cycle, typically coinciding with spermio genes is in late summer, early autumn. Ducti epididymi… Advisors/Committee Members: Van Wyk, J. H., Leslie, A. J., Stellenbosch University. Faculty of Science. Dept. of Botany and Zoology..

Takođe je proučavan i uticaj navedenih faktora na varijabilnost osobina izdanaka M. perennis (visine biljke, broja listova i broja internodija). S obzirom na to da je M. perennis dvodoma biljka, analizirano je i prisustvo polnog dimorfizma i potencijalnih polno–specifičnih reakcija na suboptimalne uslove staništa. Uticaj heterogenih uslova svetlosti i aerozagađenja na stepen integracije oblika različitih delova cveta I. pumila procenjivan je na osnovu obrazaca korelacionih odnosa. Biljne vrste M. perennis i I. pumila su se u dosadašnjim istraživanjima pokazale kao pogodni model–sistemi za istraživanja u oblasti evolucione biologije biljaka. Šumski prosinac, Mercurialis perennis L. (Euphorbiaceae), je dvodoma višegodišnja zeljasta biljka, karakteristična pre svega za stara šumska staništa, primarna ili manje narušena, ali se može naći i na otvorenim, kao i na staništima pod jakim antropogenim uticajem. Kao dvodoma vrsta, predstavlja atraktivan objekat za proučavanje različitih aspekata polnog dimorfizma kod biljaka. Patuljasta perunika, Iris pumila L. (Iridaceae), je višegodišnja monokotila iz grupe geofita, karakteristična je pre svega za otvorena, uglavnom suva nizijska do brdska staništa. U ovo istraživanje uključene su populacije M. perennis sa lokaliteta Avala i Bele stene (Kopaonik), kao i populacije I. pumila sa lokaliteta Deliblatska peščara i Beograd. Pored toga, analizirani su i cvetovi I. pumila gajeni u eksperimentalnim uslovima jasno definisanog intenziteta i kvaliteta svetlosti. Analizirano je 90 biljaka M. perennis i 120 biljaka (ukupno 60 genotipova) I. pumila sa prirodnih staništa izloženih heterogenim uslovima svetlosti, 170 biljaka (33 genotipa) I. pumila gajenih u eksperimentalnim uslovima pod različitim svetlosnim tretmanima, kao i 119 biljaka M. perennis i 120 biljaka (41 genotip) I. pumila sa staništa izloženih različitom nivou antropogeno indukovanog stresa...

▼ Understanding the ultimate and proximate factors underlying patterns of phenotypic variation is a key goal in the study of behavioral and evolutionary ecology. Organisms commonly show variation in body size and reproductive behavior. Such variation is interesting because it can represent adaptations to the environment. In my dissertation I used horseshoe crabs, Limulus polyphemus, to explore the ultimate and proximate factors underlying variation in: 1) body size across populations, 2) size between males and females within a population, and 3) reproductive behavior among male within a population. In Chapter 2, I examined size at maturity, which is one of the most fundamental traits of an organism. My investigation into large-scale patterns of body size distribution discovered that horseshoe crabs are one of just a few species to show a dome-shaped distribution in body size. This pattern appears to be due to how temperature, season length, salinity, oxygen levels, and food abundance affects juvenile mortality and growth rates that control body size. What is the ultimate explanation for why females and males same species rarely have the same adult body size? Sexual size dimorphism (SSD) is thought to be a result of disruptive selection on body size between the sexes, due to reproductive roles. SSD is likely the product of a suite of conflicting pressures on each sex. In Chapter 3, I evaluated fived hypotheses to explain the evolution of SSD, and conclude that fecundity selection favoring late maturity and large female size, along with protandry favoring earlier maturity and small male size, are the likely selection pressures responsible for SSD in this species. Horseshoe crab males exhibit two condition-dependent, alternative mating tactics: males in better condition arrive on spawning beaches attached to females, while males in poorer condition join spawning pairs as “satellites”. In Chapter 4, I investigated a cost to the attached male tactic that has not been considered previously: a restricted ability to feed. My results indicate that a period of nutritional stress caused by reduced food consumption is a cost of the attached tactic; and may explain why the alternative reproductive tactics take the form they do in this system.

The reproduction in insects is affected by a wide array of factors that acts directly on the reproductive output, related with offspring quality and quantity: the interaction, by physical, chemical and visual cues, between insects and host plants; the larval growth rate affecting adult size and mating rate, as a mechanism of reproductive sucess. Thus, studies on insect reproduction are recommended to help estimate and to understand population dynamics, for both endangered species and to control crop pests. The tomato fruit borer Neoleucinodes elegantalis Guenée (Lepidoptera: Crambidae) is one of the most important pest species on Solanaceae in Brazil, and the aims of this works is to study this species regarding to: (i) the role of physical, chemical and visual cues on oviposition; (ii) the causes of sexual dimorphism and (iii) how male mating history affects his ability to obtain new matings. This work also propose an equation that can help to estimate the initial size of fragmented spermatophores found inside the reproductive tracts of females, based on measures of the fragments. The results showed: (i) that physical and chemical cues increase significantly the oviposition of N. elegantalis, as well showed that light intensityalso affect oviposition; (ii) that differences in dayly growth rate is the cause of the observedsexual dimorphism in this species, and (iii) that recently mated males are equally able to achieve new matings as virgin ones, within at least 24-h period.

The Neotropical damselfly Telebasis carmesina (Odonata: Coenagrionidae) is a common species in the Cerrado, a Brazilian savanna and even though, nothing is known about its natural history and ecology. This study aimed to investigate the population ecology, the habitat use and the breeding behavior of this species. It was conducted at a pond in the Natural Particular Reserve at Clube de Caça e Pesca Itororó de Uberlândia, between July/2008 and October /2009. The data was collected through the markrecapture method, using an insect net and a metal precision caliper. In addition, 81 hours of behavioral observations was taken. An amount of 1133 individuals were captured. December and November/2008 comprised the highest number of marked males, while September and October/2008 presented the higher abundance of females. The abundance of individuals was directly related to the air temperature and relative air humidity and it affects the individuals size, that is, the bigger the males abundance, the smaller was the total length of them, which generally are smaller than females. The males size also varied between the seasons of the year, except in summer and auntumn, and the females had different average of sizes between spring and summer months. The males longevity varied between the seasons and during the breeding season October to April was 7,099 (0,719; XSE) days. In this study, both males and females had concentrated mainly in the pond and used the macrophytes Eliocharis sp. and Pontederia parviflora as main perching surface, mating and oviposition. The polygynous mating system through scramble competition was evidenced during observations and supported by the smaller size of males and the absence of territory guarding behavior. The breeding behavior was frequently observed during the midmorning. T. carmesinas mate involved sperm transfer to edeagous, tandem and wheel positions and some evidences suggest that there is males sperm displacement in the species. The oviposition occurs together with the male, in tandem. Sex ratio varied throughout the months, with the closest value in relation to 1:1 ratio in September (1:3,48) and the most distinct value in January (1:27,4). Males exhibited three types of aggressive displays, similarly to other studies in literature: i) chase, when a male run after other male, going back to its original position or its position is displaced by the other male; ii) threat display or wing spread, when a male, realizing the approach of another male, spreads his wings, and iii) attack, which can occurs through the use of the legs, abdominal appendages or mouth parts. The agonistic behavior is directed toward to conspecific males; however aggressive interactions can also occur between heterospecific individuals. Telebasis carmesina presents important features related to sexual selection, such as sexual size dimorphism and sex ratio male biased. Moreover, the habitat use by males and females are spatially and temporarily different.

▼ By performing a comparative analysis and using phylogenetic relationships of the Cervidaefamily this study aimed to address whether or not sexual selection may play a role in the extinctionof species by making species more vulnerable to extinction. The role of sexual selection in makingspecies more vulnerable to extinction is largely unexplored, and several factors such as ecologicaland life history traits may increase the risk of extinction.In all species of the family Cervidae (Gilbert et al. 2006, Geist 1998,Groves and Grubb2011,Meijaardand Groves2004,Price et al. 2005, Goss 1983) sexually selected characters plays amain role in determining species status and thus potentially their probability of extinction. In thisstudy the intensity of sexual selection (measured as sexual size dimorphism, antler size and matingsystem) and the rate of extinction (IUCN classification and anthropogenic effect) were counted asfactors to determine the role of sexual selection intensity in both species-rich and species-poorclades.By using the programme MESQUITE and phylogenetic trees, the results show an associationbetween species with larger body size and dimorphism, living in open habitats and having largerantler size expanded to more than three tines; such species are mostly non-territorial and formharems during the rutting season. The small species are territorial, live in closed habitats, aremonomorphic and have small antler size limited to two tines or less. Moreover species that aremore subjected to habitat degradation and anthropogenic effects tend to become smaller in size.Extinction risk for the species-rich clades with small sized, territorial and small antler sizedspecies is lower than for those consisting of species with larger antler size, larger body size, livingin open habitats and using harems as mating system.To sum up, the intensity of sexual selection in larger species in deer family put them in risk ofextinction; but on the other site, small species are more adapted to the environment by choosingdifferent strategy in mating system, and reducing antler and body size thus diminishing theextinction risk.

▼ Apesar dos morcegos hematófagos serem muito estudados, diversos aspectos de sua biologia e de seu papel na transmissão da raiva ainda não são conhecidos. O objetivo da presente tese foi estudar os abrigos diurnos, os agrupamentos e o comportamento agonístico do morcego hematófago comum, Desmodus rotundus, e sua relação com a raiva dos herbívoros no Vale do Paraíba. Foi possível também obter informações sobre as duas outras espécies de morcegos hematófagos, especialmente de Diphylla ecaudata. Entre 2011 e 2014, dados sobre abrigos diurnos, composição dos agrupamentos, lesões corporais, diagnóstico de raiva e sorologia antirrábica de D. rotundus foram obtidos nos municípios de Jacareí, Paraibuna, Pindamonhangaba, Salesópolis, Santa Branca e São Luiz do Paraitinga no Vale do Paraíba, Sudeste do estado de São Paulo, Sudeste do Brasil. Foram estudados 14 abrigos diurnos de D. rotundus, dos quais 12 eram construções abandonadas na área rural. Desmodus rotundus partilhou abrigos diurnos com apenas cinco espécies de filostomídeos: Diphylla ecaudata, Chrotopterus auritus, Carollia perspicillata, Glossophaga soricina e Anoura caudifer. O tempo de recolonização desses abrigos diurnos por D. rotundus foi em média 12,5 meses, com uma variação entre três e 25 meses. O tamanho dos agrupamentos variou de dois a 79 indivíduos, com uma média de 15,6 morcegos/grupo. Fêmeas foram encontradas em 15 agrupamentos, com uma média de 13 fêmeas e uma variação entre uma e 55 fêmeas/grupo. Por outro lado, machos estiveram mais presentes nos agrupamentos, ocorrendo em quase todos (N=21), com uma média de 7,1 machos/grupo e uma variação de um a 24 machos. Sete agrupamentos foram considerados de machos solteiros. Onze dos 22 agrupamentos eram constituídos de colônia e grupo de machos solteiros. O dimorfismo sexual no comprimento do antebraço de D. rotundus do Vale do Paraíba foi estatisticamente significativo e sugere que as fêmeas são maiores 13 do que os machos. Lesões corporais, atribuídas às mordeduras provocadas por outros morcegos, foram encontradas em 76,7 por cento dos indivíduos de D. rotundus, tanto em machos como em fêmeas. A região mais atingida foram as membranas alares, com 68 por cento , porém lesões nas orelhas, face e membros foram menos frequentes (23,1 por cento nas fêmeas e 26,9 por cento nos machos). Acredita-se que as lesões nessas regiões sejam mais importantes nos mecanismos de transmissão de raiva. Apesar de ter analisado 310 amostras de encéfalos de D. rotundus do Vale do Paraíba, o resultado foi negativo em todas as amostras. A sorologia mostrou que todos os morcegos apresentaram positividade em diferentes graus. Contudo, se considerarmos o ponto de corte 0,5 UI/ml, o número de indivíduos positivos caiu para 30,1 por cento (N=90), sendo 30,9 por cento nas fêmeas e 28,8 por cento em machos. Apesar de nenhum indivíduo de D. rotundus positivo para a raiva ter sido encontrado no Vale do Paraíba durante a presente tese, a sorologia positiva de, pelo menos, 30 por cento mostra que há vírus da raiva circulando em sua… Advisors/Committee Members: Marrelli, Mauro Toledo.

▼ This thesis investigated aspects of foraging and reproductive ecology of little penguins Eudyptula minor in the eastern Great Australian Bight. Little penguins are permanent residents in this region and the link between their ecology and their local food source is poorly understood in the Great Australian Bight. Most little penguin colonies in South Australia are small in population (< 4000 breeding individuals) and they are almost all found on islands. Despite similarities in breeding seasons and diet among colonies, the foraging ecology of penguins from offshore colonies differed from inshore colonies in the same region. Natural variation in diet and foraging behaviour at eight colonies was attributed to differences in food availability. Inter-colony differences in foraging behaviour and effort, which were consistent between years, were related to differences in penguin morphology, growth and body size. Breeding penguins from the offshore colony travelled up to 3 times further from shore (39 vs. 13-21 km) and for greater durations (3 vs. 1 days), and spent more time diving (56 vs. 37 % of foraging time). Results suggest that food availability is depleted, or not profitable in near colony waters, possibly as a consequence of increased or prolonged predation by the large penguin population. This study also indicated that increased foraging effort at the colony level was reflected in the growth parameters of offspring, because offshore colonies had smaller offspring and adults, and delayed development of sexual size differentiation in bill morphology. Increases in foraging distance and duration were also linked to poorer breeding success. Little penguins at different colonies exhibited low variation in their diet because juvenile Australian anchovies Engraulis australis were mainly targeted as a food source. Dive behaviour was similar among colonies, despite differences in the depths around colonies. The regional availability and abundance of anchovies may be responsible for the unusual pattern of winter breeding that is apparent in South Australia. Little penguin diet, breeding and foraging parameters may provide quantitative indicators of the health of local anchovy stocks, especially if an anchovy fishery develops in South Australia. Baseline information on these penguin parameters parameters may also inform management decisions aimed at conserving penguin populations across the region.

▼ The study of contemporary evolution and eco-evolutionary dynamics is classically defined in terms of genetic evolution, but the actual suite of processes driving contemporary trait change is likely much more complex than often credited. This dissertation considers additional mechanisms of trait change that might be important to an emerging model system for study of contemporary evolution and eco-evolutionary dynamics. Specifically, the research focuses on phenotypically plastic and demographic trait variation in Eastern and Western Mosquitofish (Gambusia affinis and G. holbrooki) facing the major ecological gradient of predation risk. Plasticity experiments employed a common-garden rearing design to manipulate fish predator cues experienced by individuals, their parents, or their grandparents and in turn quantify reaction norms in mosquitofish size, shape, and behavior. The two species of mosquitofish showed divergent plastic responses in behavior, with the relatively bolder G. holbrooki becoming even bolder in response to predator cues. In contrast, males and females within species showed parallel behavioral responses. Despite strong sexual dimorphism, both sexes and both species showed parallel patterns of plasticity toward streamlining of body shape when exposed to predators. Interestingly, mosquitofish also showed evidence of transmitting predator cues across generations, where female G. affinis become shyer and more streamlined when their parents or grandparents experienced predators. In contrast, male G. affinis showed little evidence of transgenerational plasticity and appear to rely more heavily on their own experience. Another set of field surveys and experiments with G. holbrooki considered the potential role of sexual dimorphism and demographic variation in sex ratios as another form of trait variation with possible community and ecosystem consequences. Natural population surveys revealed female-biased sex ratios and higher primary production in the absence of predators. Mesocosm experiments suggested males and females differed in dietary preferences and that both sex ratio and density influence community responses. Although these findings support a need to expand the current eco-evolutionary synthesis to mechanisms beyond just genetic evolution, they also support some general patterns in these mechanisms and ways in which they might work with evolution to produce an even more dynamic interaction of ecology and trait change in nature.

▼ Early hominins present an unusual pattern of sexual dimorphism. On one hand, the canine teeth of these species are weakly size-dimorphic, vertically short, and nonhoning, suggesting a social system characterized by infrequent, low-intensity intermale competition and monogamous pair-bonding. On the other hand, marked size variation in skeletal remains attributed to species of Australopithecus is thought to reflect strong body-mass dimorphism, which is more consistent with intense intermale competition. Reconciling these conflicting signals and understanding their adaptive significance is a major goal of paleoanthropology. This dissertation research contributes to this objective by investigating factors that may constrain or reduce canine height in extant anthropoid primates. Two hypotheses regarding the relationship between canine height and other elements of the masticatory system were tested using phylogenetic comparative methods. According to the first hypothesis, canine reduction is a pleiotropic by-product of changes in the sizes of other components of the dentition. With respect to canine height, the results of this study fail to support this idea. There is limited evidence for a relationship between basal canine crown dimensions and incisor and postcanine size, but significant interspecific correlations between these variables are not strong and are restricted primarily to the female maxillary dentition. These results indicate that if pleiotropy influences canine size, then its effects are weak. The second hypothesis proposes that canine reduction is a consequence of selection for increased jaw-muscle leverage. This hypothesis receives some support: there is a clear inverse relationship between canine height and the leverage of the masseter muscle in male anthropoids. Females do not exhibit this association due to the fact that dimorphism in muscle leverage is weak or absent in most anthropoid species; in other words, female muscle leverage tracks male muscle leverage, which is linked to canine height. Leverage of the temporalis muscle is not correlated with canine height in either sex. Two specimens of the 3.0-3.7-million-year-old hominin Australopithecus afarensis fall at or beyond the upper end of the great ape range of variation in masseter leverage, which is consistent with the idea that hominin canine evolution was influenced by selection for increased jaw-muscle leverage.

▼ A molts peixos gonocoristes, el sexe és plàstic donat que pot ésser alterat per la influència de factors ambientals. En aquesta tesi, utilitzant el llobarro (Dicentrarchus labrax) com a model, un peix teleosti amb un sistema poligènic de determinació del sexe influït per l'ambient, hem estudiat els efectes de diferents factors ambientals —incloent la disponibilitat d'aliment, temperatures elevades i presència d’estrògens— en el creixement, la diferenciació sexual i el desenvolupament gonadal dels juvenils. L'anàlisi global de l'expressió gènica s'ha realitzat mitjançant un xip d’ADN fet a mida. Hem trobat que, de la mateixa manera que ocorre en els mamífers, el sexe determina el creixement i que les primeres diferències en el creixement vinculades amb el sexe s'estableixen prèviament a l'aparició dels primers marcadors moleculars indicatius del sexe. A més, el transcriptoma de testicles juvenils està influït per un creixement pobre durant la diferenciació sexual, mentre que un subministrament adequat de menjar durant l’etapa juvenil és capaç de rescatar el transcriptoma testicular d’animals amb un pobre creixement previ. Hem trovat que la masculinització observada anteriorment com a resultat de les temperatures elevades està causada per efectes persistents a nivell transcriptòmic, afavorint l'expressió de gens relacionats amb el desenvolupament masculí i disminuint la dels gens relacionats amb el desenvolupament femení. Per contra, l'exposició a estrògens afecta negativament tant als gens relacionats amb el desenvolupament masculí com el femení. És destacable com els patrons d'expressió d'una sèrie de gens relacionats amb la regulació epigenètica de l’expressió gènica mostren graus diferents de dependència a factors genètics, període del desenvolupament i factors ambientals segons la seva categoria funcional.

▼ Assessment of trophic interactions between increasing populations of New Zealand fur seals (Arctocephalus forsteri) and fisheries in southern Australia is limited due to a lack of species specific demographic data and an understanding of the factors influencing population growth. To establish species specific demographic parameters a cross-sectional sample of New Zealand fur seal females (330) and males (100) were caught and individually-marked on Kangaroo Island, South Australia between 2000 and 2003. The seals were aged through examination of a postcanine tooth, which was removed from each animal to investigate age-specific life-history parameters. Annual formation of cementum layers was confirmed and accuracy in age estimation was determined by examination of teeth removed from individuals of known-age. Indirect methods of assessing reproductive maturity based on mammary teat characteristics indicated that females first gave birth between 4-8 years of age, with an average age at reproductive maturity of 5 years. Among reproductively mature females, age-specific reproductive rates increased rapidly between 4-7 years of age, reaching maximum rates of 70-81% between 8-13 years, and gradually decreased in older females. No females older than 22 years were recorded to pup. Age of first territory tenure in males ranged from 8-10 years. The oldest female and male were 25 and 19 years old, respectively. Post-weaning growth in females was monophasic, characterised by high growth rates in length and mass during the juvenile growth stage, followed by a gradual decline in growth rates after reproductive maturity. In contrast, growth in males was biphasic and displayed a secondary growth spurt in both length and mass, which coincided with sexual and social maturation, followed by a rapid decline in growth rates. Age-specific survival rates were high (0.823-0.953) among prime-age females (8-13 yrs of age) and declined in older females. Relative change in annual pup production was strongly correlated with reproductive rates of prime-age females and adult female survival between breeding seasons.
