▼ The advent of sexual reproduction in early evolutionary history had profound effects on the evolution of animals. In most sexually reproducing species, males and females have distinct morphological and behavioral differences that are shaped by the evolutionary imperatives of each sex. Underlying the behavioral differences between males and females are distinct and measurable dimorphisms in the nervous system. These dimorphisms can arise in the form of connectivity, neurotransmitter usage, gene expression or combinations of all three. The androdioecious nematode Caenorhabditis elegans, with its stereotyped development and simple nervous system, offers a remarkably powerful system for studying the conserved mechanisms of sex determination that shape neural development. In this thesis, I present my work on the characterization of several genes that regulate the development of sexual dimorphisms in the nervous system. The first part of the thesis concerns the characterization of the gene ham-3, which codes for a subunit of the C. elegans ortholog of the SWI/SNF chromatin remodeling complex. ham-3 is required for the proper terminal differentiation of the HSN, a serotonergic neuron of the sex-specific nervous system, which it manages by regulating the expression of transcription factors required for crucial steps of migration, axon guidance and serotonergic fate adoption. The second part of the thesis concerns the investigation of sexually dimorphic pruning mechanisms. I show that unc-6/Netrin is subject to direct transcriptional repression in hermaphrodites by tra-1, the master transcriptional regulator of sexual fate determination in C. elegans. This regulation is required for the proper timing of the sexually dimorphic pruning of synapses in the tail region in hermaprhodites. In males, where unc-6 is not repressed by tra-1, unc-6 expression perdures into adulthood and the synapse is maintained. Together, these data provide insight into the ways in which conserved genetic and developmental mechanisms manage the generation differentiation, connectivity, and maintenance of sexually dimorphic nervous systems.

▼ As a result of male-centric, northern-hemisphere-biased sexual selection theory, elaborate female traits in songbirds have been largely overlooked as unusual or non-functional by-products of male evolution. However, recent research has revealed that female song is present in most surveyed songbirds and was in fact the ancestral condition to the clade. Additionally, a high proportion of songbird species have colourful females, and both song and showy colours have demonstrated female-specific functions in a growing number of species. We have much to learn about the evolution and functions of elaborate female traits in general, and female song in particular. This thesis extends the horizons of female birdsong research in three ways: (1) by revealing the broad-scale evolutionary relationship of female song and plumage elaboration across the songbirds, (2) by developing new accessible tools for the measurement and analysis of song complexity, and (3) by showing—through a detailed field study on a large natural metapopulation—how vocal culture operates differentially in males and females. First, to understand the drivers of elaborate female traits, I tested the evolutionary relationship between female song presence and plumage colouration across the songbirds. I found strong support for a positive evolutionary correlation between traits, with female song more prevalent amongst species with elaborated female plumage. These results suggest that contrary to the idea of trade-off between showy traits, female plumage colouration and female song likely evolved together under similar selection pressures and that their respective functions are reinforcing. Second, I introduce new bioacoustics software, Koe, designed to meet the need for detailed classification and analysis of song complexity. The program enables visualisation, segmentation, rapid classification and analysis of song structure. I demonstrate Koe with a case study of New Zealand bellbird Anthornis melanura song, showcasing the capabilities for large-scale bioacoustics research and its application to female song. Third, I conducted one of the first detailed field-based analyses of female song culture, studying an archipelago metapopulation of New Zealand bellbirds. Comparing between male and female sectors of each population, I found equal syllable diversity, largely separate repertoires, and contrasting patterns of sharing between sites—revealing female dialects and pronounced sex differences in cultural evolution. By combining broad-scale evolutionary approaches, novel song analysis tools, and a detailed field study, this thesis demonstrates that female song can be as much an elaborate signal as male song. I describe how future work can build on these findings to expand understanding of elaborate female traits. Advisors/Committee Members: Brunton, Dianne (advisor).

▼ Birdsong and its function is well studied in terms of male-male competition and female-mate choice. This has generated a male bias in the song literature and the dilemma that little is known about female song. However, recent research posits that female song is not only common but is also the ancestral state of songbirds. Therefore, it is timely that I investigate the ontogeny, structure and production of female song within the context of the life history of female songbirds in order to increase our current understanding of the function and evolution of birdsong. In this thesis, I use a wild population of New Zealand bellbirds (Anthornis melanura) as a model species. The New Zealand bellbird is ideal for this research as they produce complex but sexually dimorphic song. With a cross-sectional approach, I found the songs of each sex diverged and became more consistent as the song developed from juveniles to adults, and that their sexually dimorphic songs developed over similar timeframes, suggesting potentially related functions. I also compared how the adult song repertoire of each sex varied over time, and found that males had larger repertoires at both the population and individual levels. The syllable repertoire of each sex changed at a similar rate due to shifts in relative abundance over time, suggesting both sexes may have analogous song functions and are potentially under similar selection pressures. Sexual variation in song could theoretically be explained by differences in the syrinx structure but there is a lack of comparative research in this field. I found that bellbirds had greater sexual dimorphism in the size of their bronchial half rings compared to species both with and without female song. This suggests syrinx size alone cannot explain sexual dimorphism in repertoire size, but may have a stronger influence on sex- and species-specific song frequencies. Long term studies provide insights to life history and my study population on Tiritiri Matangi Island has breeding data available as far back as 1977. The island’s history of ecological restoration has resulted in exponential growth of the bellbird population, and I found correlated reproductive trade-offs with a reduction in clutch size over time, likely owing to increasing competition for resources. My research demonstrates how female songbirds develop and change their song over time and that they have flexible life-history traits that enable them to cope with changing breeding conditions. My research is significant in that it is one of the first to study female song in a wild population and provides important insights into male and female song development, structure and role.

▼ Research into the evolutionary function of elaborated colouration in birds is continually ongoing. Novel approaches to addressing various aspects of this broad research area may help us consider this topic in a new light. This thesis aimed to consider two different aspects of avian colouration research using novel methods and testing relatively new hypotheses. Firstly, I consider the cost of carotenoid pigmented ornamental colouration - an area of research that is currently under intense debate. Classically carotenoid-based pigmentation has considered carotenoids to function as indicators of sexual quality, with costs being due to carotenoids being diet dependent in birds. Recent research however has argued that carotenoid pigmented colour traits function in agonistic social contexts, and that the cost of using carotenoid pigmentation as an honest indicator of quality is a social one. In this study I test this hypothesis using blackbirds (Turdus merula) and their natural variation in carotenoid-based bill colouration. I replicate a study using model presentations to simulate territory intrusions. Additionally, I examine the feasibility of using three-dimensionally printed models in avian behavioural studies. This study was unsuccessful due to a lack of response rates from territorial males, however it was successful in questioning several differing aspects between my study and the study I replicated. Secondly, I explore the spatial organisation of colouration on the bodies of birds as a way of potentially inferring different functions of elaborate colour traits. In the third chapter I develop a novel method that allows objective analysis of the spatial organisation of colour on the bodies of birds, by removing morphological variation between species. Using this method I present a case study on the spatial organisation of colour elaboration in 2,471 species of passerines. This case study uses a difference in sexual dichromatism as a proxy for colour elaboration and determined where signaling hotspots occur on the bodies of birds. These results demonstrate that conspicuous colouration is most common in the supercilium, chin, and upper breast of passerine birds. In chapter four, I used this method to determine correlations between different life-history traits and different regions of the body. This study aimed to infer the function of different regions of the head in signaling. My results show that the irises in species with tropical life-histories and cooperative breeding strategies are more likely to be elaborately coloured; bills of larger bodied species are more likely to be elaborately coloured than are smaller species; and the spatial organisation of colour effects females more than it does males.

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.

Resumo: As dores crônicas representam um grande problema de saúde pública, sendo o sexo feminino mais afetado. Como estratégia farmacológica ao controle da dor, os ligantes de receptores ativados por peroxissoma gama (PPAR?) vêm sendo estudados em diversos modelos experimentais. Entre os ligantes de PPAR?, estão a prostaglandina 15d-PGJ2 e a pioglitazona. Esses ligantes diminuem a hiperalgesia mecânica e térmica, através da diminuição de marcadores do processo inflamatório e da atividade neuronal nociceptiva na periferia e no sistema nervoso central. No entanto, o efeito desses ligantes em diferentes modelos de hiperalgesia, como dor muscular e sua ação de forma sexo-dependente na dor pós-operatória, neuropática associada a diabetes tipo II e neuropática induzida pelo modelo de lesão nervosa, tem sido pouco explorada ou ainda é desconhecida. Portanto, o objetivo geral do presente estudo foi avaliar o efeito analgésico dos agonistas de PPAR? em diferentes modelos de hiperalgesia. Especificamente foi avaliado: 1) se a administração intramuscular de 15d-PGJ2 reduziria a hiperalgesia muscular mecânica induzida pela carragenina e pela contração estática, e em caso positivo, se esse processo seria modulado por opióides; 2) se a administração sistêmica da pioglitazona diminuiria a hiperalgesia mecânica e térmica induzida pela dor neuropática induzida pela secção nervosa ou se a administração da pioglitazona via sistêmica ou intratecal diminuiria a hiperalgesia mecânica induzida pela dor pós operatória, de maneira sexo-dependente em ambos os modelos; 3) se a pioglitazona administrada sistemicamente ou cronicamente via dieta reduziria a hiperalgesia mecânica ou térmica induzida pela neuropatia diabética, de maneira sexo dependente. O teste de Randall Selitto foi utilizado para avaliar a hiperalgesia mecânica muscular, enquanto o teste de von Frey filamentos foi utilizado para avaliar a hiperalgesia mecânica nos demais modelos experimentais. A hiperalgesia térmica foi avaliada pelo teste da acetona no modelo de hiperalgesia neuropática induzida pela secção nervosa e pelos testes coldplate e hotplate no modelo de hiperalgesia neuropática diabética. Os resultados demonstram que 1) a 15d-PGJ2, via receptores PPAR?, bloqueou a hiperalgesia muscular induzida pela carragenina e pela contração estática. Especificamente na hiperalgesia muscular induzida pela carragenina, esse processo foi modulado pelos receptores opióides. 2) pioglitazona sistêmica diminuiu a hiperalgesia mecânica e térmica, induzida pela dor neuropática induzida pela secção nervosa, enquanto pioglitazona intratecal, mas não sistêmica, diminuiu a hiperalgesia mecânica induzida pela dor pós-operatória, sem diferença…

▼ Sexual dimorphism, or phenotypic differentiation of the sexes, is widespread amongst animals. It is understood mainly in the context of sexual selection, i.e. selection on mating success, with such selection typically acting more strongly on males. In some cases however, conspicuous ornaments similar to those observed in males are expressed in femalesâ€”but the causes for their evolution have often been elusive. In my dissertation I examine the behavioral, hormonal, and genetic correlates of female throat colorationâ€”a male typical traitâ€”in the threespine stickleback fish (Gasterosteus aculeatus), to test whether the evolution of the female trait might be attributed to adaptive or nonadaptive mechanisms. My results indicate that while male-typical throat color in females is associated with some components of fitness, e.g. body size and growth, it does not reflect reproductive readiness or body condition. Also, red-throated females are not socially more dominant or aggressive than dull-throated females in either dyadic or socially complex contexts. Further, the masculinized female trait is not associated with variation in fish-specific androgen mechanisms, 11-ketotestosterone and its cognate receptor, suggesting that the female trait is not under the principal male-specific endocrine control. Investigating the genetic basis of throat coloration I find that that the same genomic regions are associated with the presence of red throat coloration in both sexes, suggesting that female throat coloration might be a genetically correlated byproduct of selection on males. In sum, using an interdisciplinary approach to studying the evolutionary causes of female ornaments, I find that the red throat in female sticklebacks is potentially a nonadaptive trait that has arisen due to a genetic correlation between the sexes; thus female conspicuous traits do not necessarily result from adaptive processes related to sexual selection on females.

▼ Sexual reproduction is an evolutionary innovation that arose 1.2 billion years ago, and in that time, has allowed a rapid diversification of species outpacing that of asexually reproducing organisms. Successful sexual reproduction in animals requires the incredible coordination of complex genetic and behavioral factors; from the most fundamental levels of ensuring correct chromosome segregation and ploidy to the most complex of behavioral mating rituals, any failure can result in a complete loss of evolutionary fitness. In this thesis, I have explored the developmental programs that function to ensure somatic sex determination, sexual differentiation, and mating behaviors in C. elegans. C. elegans is an androdiecious nematode species that has been extensively characterized in regard to the sexual dimorphism of its development, nervous system, and behavioral outputs. Sex determination pathways are widely diverged across phyla, and C. elegans has coopted a Gli family transcription factor to serve as a cell autonomous global regulator of somatic sex determination. I investigated the expression of this transcription factor, tra-1, with cellular, subcellular, sex-specific, and temporal resolution in both sexes of C. elegans and found that it is dynamically regulated to control sex determination. In contrast to the upstream sex determination pathway, genes that control downstream sexual differentiation in animals display much higher functional conservation, and many of the regulators of sexual differentiation belong to a family of transcription factors known as the DMRT family. Downstream of the tra-1 global regulator, I found that the highly conserved DMRT family gene dmd-4 acts much more specifically in adult hermaphrodites to generate sexual dimorphism at the level of the phasmid sensory neurons PHA and PHB. Furthermore, the sexual dimorphism of DMD-4 is regulated post-translationally by a ubiquitin-binding domain that I also found to be functionally conserved in the human ortholog, Dmrt3. Although these transcription factors both demonstrate the high degree of genetic control that contributes to sex determination and sexual differentiation, I also described male-specific effects of early life stress on sexual dimorphic synaptic connectivity and behavior generated by the phasmid sensory neurons, indicating that sexual differentiation is also plastic to environmental cues encountered during the life of an organism. This thesis provides insight into how genetic pathways function at multiple levels to give rise to extensive sexual dimorphism in the soma of an animal, both globally and in regard to the development on individual cells, in addition to the ways in which these genetic pathways can be modified by environmental factors and organismal life history.

▼ Numerous studies have found population variations in craniofacial traits and sexual dimorphism of the human face, but little research has been done to investigate the impact of ancestry on sexual dimorphism. This thesis quantified the degree of sexual dimorphism across seven population samples (West African, East Asian, Irish, Italian, Polish, Portuguese, and South Asian) and examined the inter- and intra-population sex variation patterns. A standard x, y, z coordinate system for 7,150 quasi-landmarks was applied to 3D faces of 3739 people aged from18 to 40. Principal Component Analysis (PCA) reduced the dimension to 44 feature variables explaining 98% of total variations. 773 individuals in the seven populations were extracted from the overall principal component (PC) space to be the focus of this study. MANOVA test on the scores of the top five PCs shows overall main effects of sex and ancestry (p-value = 0) and a sex*ancestry interaction term (p-value = 0). Univariate Two-way ANOVA further confirms the existence of main effects in every single PC (p value =0) and that interaction effect is present only in PC2 (p-value = 0.0017, family-wise alpha rate = 0.01). Then the levels of sexual dimorphism were calculated in two different ways: 1) as sex differences between averaged male- and female faces of a population group, illustrated by the visual patterns of sexual dimorphism between average faces; 2) as averaged individual sex differences, supplemented by intra-sex facial variability. These sample estimates were computed using two distance methods, Mahanalobis and Root-mean-square error (RMSE). The ancestry differences in the expression of sexual dimorphism were discovered by generating the 95% bootstrap confidence intervals for the sample statistics from 10,000 bootstrap replicates, One-way ANOVA and multiple comparisons of unequal group means on the bootstrap distributions of sex distances. Lastly, the population groups are ranked based on their Mahanalobis and RMSE sexual dimorphism distance sample mean, bootstrap mean validated by ANOVA and Tukey’s HSD test. We found that in the level of sexual dimorphism between consensus faces, East Asians rank the highest in both Mahanalobis and RMSE distance measures. Irish ranks the lowest in Mahanalobis distance, while West Africans rank the lowest in RMSE distance. When sexual dimorphism is calculated as the average individual face sex differences, East Asians rank the lowest and West Africans the highest in Mahanalobis distance, whereas West Africans rank the lowest and South Asians the highest in RMSE distance.

Resumo: Paraselenis (Sphaetiechoma) flava (L., 1758) pertence à tribo Mesomphaliini (Chrysomelidae: Cassidinae s. str.), cuja distribuição é Neotropical. Esse besouro encontra-se associado à Ipomoea aristolochiaefolia (H. B. K.) Don. (Convolvulaceae) e Ipomoea batatas (L.) Lam. (Convolvulaceae) e apresenta o comportamento de cuidado materno, que se estende do ovo até a emergência dos adultos. Embora haja alguns estudos que foquem no comportamento materno dessa espécie, ainda é incipiente o conhecimento sobre o seu hábito reprodutivo e aspectos funcionais da morfologia em relação ao comportamento reprodutivo e agonístico. O propósito deste estudo foi avaliar os comportamentos reprodutivos, dentre os quais se destacam o combate entre machos (comportamento agonístico), aspectos da morfologia e os processos pré copulatórios envolvidos na seleção sexual de P. flava. Populações dessa espécie apresentaram tempo de desenvolvimento na fase de ovo diferente nas duas plantas hospedeiras avaliadas: I. aristolochiaefolia e I. batatas. O estudo morfométrico evidenciou diferenças significativas no comprimento da antena, largura total, comprimento da região humeral entre fêmeas e machos na população estudada, porém não foi possível elucidar sobre a direção evolutiva do processo de seleção sexual. O comportamento agonístico entre machos de P. flava não está relacionado a uma área específica e nem mesmo a um recurso limitado, não configurando assim, como comportamento territorial, conforme conceito utilizado. Os processos pré-copulatórios avaliados não foram suficientes para determinar os processos envolvidos no dimorfismo sexual, sendo que esses podem ser explicados em futuros estudos reprodutivos

Paraselenis flava (L. 1758) is a species of beetle belonging to the Mesomphaliini tribe (Chrysomelidae: Cassidinae s. str.), whose distribution is Neotropical. This beetle is associated with Ipomoea aristolochiaefolia (H.B.K.) Don. (Convolvulaceae) and Ipomoea batatas (L.) Lam. (Convolvulaceae) in the Universidade Estadual de Campinas (Unicamp) campus and surrounding areas. It presents maternal care behavior, which extends from the egg until the emergence of adults. Although there are some studies that focus on the maternal behavior of this species, knowledge about its reproductive behavior and functional aspects of morphology in relation to behavior is still incipient. Thus, the purpose of this study was to evaluate the ecological relationships between reproductive behaviors, among which stand out the fight between males (agonistic behavior), aspects of morphology and the processes involved in sexual selection in this species. P. flava populations showed different egg development time in the two evaluated host plants. The…

▼ I examine some of the ecological and evolutionary implications of body size in hermit crabs, with special emphasis on the upper intertidal species Clibanarius digueti. In Chapter 1 I show that body size had a far greater effect than species identity on desiccation tolerance for shell-less individuals of C. digueti, Paguristes anahuacus, Pagurus lepidus, and Phimochirus roseus. In contrast with other intertidal taxa, there was no correlation between the upper tidal limit of a species and the expected desiccation tolerance of an average-sized, shell-less individual of that species. This suggests that the gastropod shell that normally houses the hermit crab is sufficient to eliminate desiccation as a community-structuring force in this guild. Clibanarius digueti exhibits strong sexual dimorphism in body size, with almost no overlap in size between adult males and females. In Chapter 2 I show that sexual differences in the intensity of selection on size favor this dimorphism. Specifically, male mating success depended more strongly on body size than did female fecundity. In fact, the rate of increase in fecundity with body size equalled the lowest previously recorded for decapod crustaceans, suggesting that sexual size dimorphism in this species may depend more on weak fecundity selection on females than on strong sexual selection on males. Documenting contemporary selection on a character, however, is not the same as documenting that selection caused the character to evolve. Chapter 3 presents the first empirical test in a single species (C. digueti) of the hypothesis that sexual size dimorphism represents an evolutionary response to sexual differences in selection on size. The test is based on a general model that predicts crab body size as a function of shell limitations, shell fit and body size. Both males and females occupied optimally sized shells of non-preferred species, but the greater the desirability of a shell species, the greater the tendency for males to occupy tighter-fitting shells than females. Males also apparently suffere higher mortality than similarly-sized females. According to the general model, these results agree with the hypothesis that differential selection is causally involved in the evolution of sexual size dimorphism, and contradict the alternative hypothesis that energetic constraints on females produce the dimorphism.

▼ Gender is a pervasive and regulating social institution that is operationalized in mainstream Western culture as a natural extension of the ontological difference perceived to exist between the binarily sexed bodies of male and female. Feminist theory has widely established, however, that gender is done - i.e., gender is not a naturally occurring phenomenon, but is an ongoing construction engaged and replicated by individual actors and which, while compulsory, is nevertheless optional. Within this canon is a small number of feminist theorists, notably Judith Lorber, Judith Bulter, and Nancy Tuana, who argue that the constructive manifestations of gender performativity (that is, doing of gender) are not limited to the social sphere. They argue the role of gender in the construction of the material body, asserting that doing gender has a constructive role in physical embodiment: what we do influences, and in fact creates, what our bodies are. This study engages feminist theory on the production of the body through a qualitative exploration of the lived experience of gendered bodily change, as described in the first-hand narratives of trans-identified individuals. I predict that the analysis of the narratives in the sample will show that in comparison to cisgender individuals, trans individuals possess a heightened awareness of the performative nature of gender, and that trans individuals consciously engage performativity in order to conform to the normative expectations associated with the desired gender role. I further predict that trans individuals experience sexually dimorphic bodily change to be a direct result of changes to their gender identity. The interview analysis findings provide mixed support for the first hypothesis, demonstrating that while trans individuals in the sample do demonstrate a heightened awareness of the ways in which gender is performed, the respondents’ insights came largely from their experiences in their compulsorily cisgender, pre-transition lives, rather than their current gender embodiments. The concept of performativity and its perceived implication of artificiality clashed with the respondents’ sense of their gendered actions as an expression of an authentic self, and my analysis thus addresses performativity as a necessarily polemic concept located between the subjectivity of the individual narratives and the theoretical position that gender is done. The findings provide a substantial level of support for the second hypothesis that trans individuals understand experienced bodily change to be a direct result of changes in gender identity. This study’s exploration of trans experiences of lived bodily change contributes a narrative perspective to the ongoing discussion in feminist theory which surrounds the role of gender in the production of the material body.

▼ Scorpions possess two integrated multifunctional weapons systems. Anteriorly, they maintain a grasping system comprised of a pair of pedipalps ending in chelae that seize and manipulate prey, ward off predators, and secure mates. Posteriorly, they wield a venom delivery system consisting of a tail-like metasoma with a stinger at the tip of the terminal segment (telson) that can be thrust into prey, predators, or mates to inject venom. Given the complexity of these systems, I hypothesized that weaponry design is subject to selective forces arising from differences in usage between the sexes, during ontogeny, and among closely-related species occupying different habitats. In the first of three studies, I examined sexual dimorphism in the North American scorpion Hadrurus arizonesis to develop a suitable statistical approach for disentangling sexual size dimorphism (SSD) and sexual body component dimorphism (SBCD), and to characterize the allometry of weaponry components. In the second study, after thoroughly reviewing the literature on venom yield in scorpions, I relied on the methodology developed in the first study to characterize venom availability in H. arizonensis. Venom yield was strongly and exponentially related to overall body size and weakly proportional to relative telson size. Venom protein concentration was weakly and negatively associated with body size, and slightly greater in females than in males. In the third study, I examined both weapon systems of two sister Smeringurus species that co-occur with H. arizonensis but occupy distinct habitats: the psammophile S. mesaensis and the lithophile S. vachoni. Males trended toward more robust chela, especially in S. vachoni. Metasoma length averaged longer in males of both species, but the telson was larger and the venom supply greater in females. Venom availability increased exponentially during ontogeny for both species. Smeringurus vachoni possessed significantly larger venom stores than S. mesaensis. Sexual and species differences likely result from different selective regimes related to survival and reproductive demands, priority in securing mates, and possibly population density and cannibalism. These findings highlight the multiple factors that influence weapons design in scorpions, and underscore the functional importance of these complex systems that are relied upon in varying roles and contexts.

▼

In many species of animals, adults of one sex grow faster or for a longer period of time to become larger than the other. Sex differences in growth rate can often be attributed to differences in androgenic versus estrogenic hormonal effects on the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis. In this paradigm, testosterone (T) stimulates hepatic IGF-1 message, resulting in an increase in plasma IGF-1, while estrogenic hormones have the opposite effect. However, this generality is inherently biased because studies have focused almost entirely on male-larger species. Previous work in lizards has demonstrated that T inhibits growth in female-larger species, while stimulating growth in male-larger species. Thus, the effect of T on IGF-1 may not be universal but may depend on a species’ pattern of sexual size dimorphism. Since IGF-1 had not previously been characterized in lizards, my research required the development of novel assay techniques. To this end, a partial sequence of IGF-1 was cloned. Comparison of the deduced amino acid sequences of IGF-1 confirmed high sequence identity (72 – 80%) between lizards and the corresponding region in human. These sequences supported the development of assays to characterize the response of IGF-1 to variation in food intake. In S. undulatus, zero ration decreased hepatic IGF-1 message and plasma IGF-1, while re-feeding restored levels to that of full ration. In yearling S. jarrovii, 1/3 ration had no effect on hepatic IGF-1 message compared to full ration. Altogether, results from nutritional manipulation in Sceloporus lizards are consistent with previous work but suggest that food restriction short of starvation may have little effect on IGF-1. Following the validation of assays, we investigated the effects of T on IGF-1 in a female-larger species, S. undulatus. Contrary to published studies on male-larger species, T decreased hepatic IGF-1 message in adult males and juvenile males and females. However, T did not affect plasma IGF-1. Our results challenge the widespread belief that males grow faster than females by increasing their production of IGF-1.

Thesis Ph. D. Michigan State University. Psychology 2017

The following dissertation examines the ventromedial nucleus of the hypothalamus (VMH), a brain region that is sexually dimorphic in rodents. The experiments in this dissertation were centered around the question of whether the VMH is sexually dimorphic in mice, and also explored the questions of what the role of circulating testosterone (T) and the androgen receptor (AR) are in this sex difference. The following chapters examine the role of circulating T and the AR in regulating the regional volume, neuron number, neuronal soma size, astrocyte number, and astrocyte complexity in the mouse VMH. The first experiment examines the question of whether sex differences exist in the mouse VMH by looking at unaltered adult male and female mice. The results showed that the VMH is larger in males than females, and that the difference is accounted for by differences in the VL and DM subregions. This experiment also examined sex differences in astrocyte number and complexity in the VMH. The results showed that males have more astrocytes than females in the VMH, and have more complex astrocytes in the VL subregion. Next, we ask if there is a role of circulating T or a functional AR in the VMH sex difference; the next study examines the role of circulating adult T and AR in VMH structure in males, females, and males without a functional AR (iTfm animals). The results showed that VMH volume, specifically of the dorsomedial (DM) and ventrolateral (VL) subregions, was greater in animals with circulating adult T regardless of genotype, including iTfm males, suggesting that T is acting through an AR-independent mechanism. Additionally, neuron number was greater in males and iTfm males as compared to females, suggesting that the sex difference in neuron number is independent of adult circulating T and AR. T treatment did lead to increased neuronal soma size in the VMH, and this response may be dependent on AR, as VMH somata were not significantly different between iTfms with or without adult T treatment. The last experiment examines the question of whether there is a role of AR or circulating T in the astrocyte sex difference using males, females, and iTfm males with and without T treatment to look at astrocyte number and complexity in the VMH. The results show that males and iTfms did not significantly differ in the number of VMH astrocytes, and both had more astrocytes than females. In the VL subregion of the VMH, adult T treatment resulted in more complex astrocytes regardless of genotype or AR status, while no differences were seen in the DM subregion. Together, these experiments show that the VMH is sexually differentiated in mice, with most of the differences being observed in the VL and DM subregions. Additionally, many of these sex differences are due to circulating T acting through an AR-independent mechanism.

The Australian zebra finch is an advantageous model for investigatingmechanisms regulating neural structure and behavior. Males and females exhibit remarkable differences in brain morphology and in the song behavior that they subserve. Thus, we can exploit these sexually dimorphic traits to begin to understand the factors that underlie development of the nervous system. While early studies implicated a critical role of estradiol (E2) in masculinizing both structure and function, Z-linked genes (males: ZZ; females: ZW) might also contribute. In the experiments conducted for this dissertation, I investigated the role of one Z-gene, tubulin specific chaperone protein A (TBCA) and its potential interactions with E2, in masculinizing the zebra finch song system. TBCA is one of several chaperone proteins involved in the formation of β-tubulin, and is critical for microtubule biosynthesis and integrity.I show that TBCA exhibits male-biased expression in the lateral magnocellularnucleus of the anterior nidopallium (LMAN). I also find that TBCA transcript and its protein product are developmentally regulated, such that this expression is higher in juveniles compared to adults. Further, TBCA is expressed in neurons that project to an efferent target, the robust nucleus of the arcopallium (RA). While the morphology of LMAN is not particularly different between the sexes, the projection from LMAN to RA is more robust in males, and this might influence masculine development of RA. Thus, TBCA is both temporally and spatially primed to influence sex-specific development.TBCA expression does not appear to be modulated by E2, as administration ofthis hormone did not influence TBCA mRNA quantity or stereological cell counts of TBCA+ cells in LMAN. However, treatment of males with the aromatase inhibitor, fadrozole, induced a hypermasculine phenotype in neural structures, including in the volume of LMAN, cell size in RA, and of the projection between these two regions.Finally, TBCA knockdown in LMAN in vivo demasculinized these samemorphological parameters in both males and females. Moreover, I did not detect an interaction between TBCA and E2 in facilitating masculine development, nor did I observe an additive effect of the two factors. Collectively, the present body of work represents an initial effort in determining the role of a Z-gene in the development of brain and behavior. The results here serve as an important platform from which wecan begin to explore the mechanisms regulating the observed effects, including those underlying cell survival and maintenance of neural projections.
