▼ Species use a variety of mechanisms to adapt to environmental change. These range from spatially tracking optimal environments, to phenotypically plastic responses and evolutionary adaptation. Due to increases in anthropogenic influence on environments, characteristics of change such as their duration and magnitude are undergoing fundamental shifts away from the natural disturbance regimes that shaped species’ evolution. This dissertation uses empirical data and simulation models to examine the ecological and evolutionary consequences of environmental change across real, heterogeneous landscapes for multiple species, with an emphasis on anthropogenic changes. I used landscape genetics to evaluate the effects of urbanization on two native amphibian species, spotted salamanders (Ambystoma maculatum) and wood frogs (Lithobates sylvaticus). Population isolation was positively associated with local urbanization and lessened genetic diversity for both species. Resistance surface modelling revealed connectivity was diminished by developed land cover, light roads, interstates, and topography for both species, plus secondary roads and rivers for wood frogs, highlighting the influence of anthropogenic landscape features relative to natural features. Further study of a subset of wood frog populations revealed adaptive evolution associated with urban environments. I identified a set of 37 loci with the capacity to correctly reassign individuals into rural or urban populations with 87.5 and 93.8% accuracy, respectively. I developed an agent-based model to examine how gene flow, rates of change, and strength of landscape spatial and temporal autocorrelation influence abundance outcomes for species experiencing an environmental shift. Analysis of 36 environmental scenarios suggests that environmental variation, which is an emergent property of landscape autocorrelation, is negatively associated with the magnitude and duration of abundance declines following environmental change. Higher levels of gene flow lessened this effect, particularly in abrupt change scenarios, although gradual changes also resulted in demographic costs. Lastly, I used an investigation of an emerging disease in American lobsters (Homarus americanus) to study within-generation responses to environmental pressures. Using whole transcriptome shotgun sequencing I identified eight differentially expressed unigenes associated with the disease and seven related to environmental differences. Collectively, my dissertation provides numerous examples of how anthropogenically induced environmental change can direct ecological and evolutionary processes. Advisors/Committee Members: Michael T. Kinnison, Cynthia S. Loftin, Malcolm L. Hunter.

▼ Understanding the origins of phenotypic innovation is a key goal in biology. Phenotypic innovation via modification of gene function can occur either through mutations in protein-coding sequences, which may result in changes of gene products, or mutations in regulatory sequences, which can affect gene expression. Although phenotypic evolution is thought to often occur through modifications in gene expression, evolution of coding sequence has been studied almost exclusively for decades. The recent availability of high-throughput RNA sequencing (RNA-seq) data provides an opportunity to examine expression evolution. Therefore, combining analyses of protein-coding sequence evolution and gene expression evolution may be crucial to answering fundamental questions in evolutionary biology. Using both types of data, a major topic of this dissertation is gene duplication, as it is a key player in genetic and phenotypic novelty. First, I use population-genetic inference to interrogate the role of natural selection in the functional evolution of young duplicate genes in Drosophila. I find that different types of selection act on genes with different levels of functional divergence, suggesting that natural selection may determine whether and how duplicate genes are retained. Second, I use multi-tissue gene expression profiles to assess functional divergence after gene duplication in grasses. I find that expression divergence is prevalent and is positively correlated with both sequence evolutionary rate and tissue specificity. Finally, I develop a new summary statistic and apply it to investigate population-specific sequence and expression divergence in three European populations. I identify candidate genes that potentially drive population-specific adaptation. Taken together, this work shows that using a combination of genetic and expression data, we are able to address critical questions in evolutionary biology.

▼ The Eastern Olympus Mons Basal Scarp (EOMBS) is conditionally stable when the edifice contains pore fluid, and critically stable, or in failure, when the edifice contains a dipping-overpressured-confined aquifer and mechanical sublayer at depth. Failure of the fault bounded portion of the flank results in estimated volumes of material ranging from 5600–6900km3, or 32–39% of the estimated volume of the “East” Olympus Mons aureole lobe. We suggest that the EOMBS faults may be an expression of early stage flank collapse and aureole lobe formation. Ages of deformed volcano adjacent plains indicate that this portion of the edifice may have been tectonically active at <50Ma, and may be coeval with estimated ages of adjacent outflow channels, 25–40Ma. This observation suggests that conditions that favor flank failure, such as water at depth below the edifice, existed in the relatively recent past and potentially could drive deformation to the present day. Coupled 3D mantle convection and planetary tectonics models are used to explore the links between tectonic-regimes, the level of internal heating (Q) within the mantle, planetary surface-temperature, and planetary lithospheric-strength. At high and low values of Q, for moderate to high yield, hot and cold single-plate planets prevail. For intermediate Q, multiple stable tectonic-states exist. In this parameter space, the specific evolutionary path of the system has a dominant role in determining its tectonic state. For low to moderate lithospheric yield strength, mobile-lid behavior (a plate tectonic-like mode of convection) is attainable for high degrees of internal heating (i.e., early in a planet’s thermal evolution). This state is sensitive to climate driven changes in surface-temperatures. Relatively small increases in surface-temperature can be sufficient to usher in a transition from a mobile- to a stagnant-lid regime. Once stagnant, a return to mobile-lid is not attainable by a reduction of surface-temperatures alone. For lower levels of Q, the tectonic regime becomes less sensitive to surface-temperature changes. These results indicate that terrestrial planets can alternate between multiple tectonic-states over giga-year timescales. Within parameter space regions that allow for bi-stable behavior, any model-based prediction as to the current mode of tectonics is inherently non-unique in the absence of constraints on the geologic and climatic histories of a planet.

▼ Evolutionary events have potentially dramatic implications for organisms. I took advantage of an evolutionary event, the loss of a sexual signal in the field cricket Teleogryllus oceanicus, to elucidate the potential consequences of such a change. In some Hawaiian populations, males possess a wing mutation, flatwing, that precludes song production, rendering them obligately silent. Signal loss has the effect of altering the acoustic landscape experienced by all crickets, representing a change in the social environment. Previous studies indicate that the lack of acoustic input alters several phenotypic traits, perhaps by changing perceived population density. I investigated the role of the acoustic environment in mediating male reproductive investment and aggressive behavior. Males reared in song-dense environments, representing populations with many rivals, invested more in the ejaculate but were less aggressive than males from silent environments. In addition, because flatwing males lack the ability to produce song, they face difficulties in attracting mates, since females locate males by responding to calling song. In some other species with multimodal communication, individuals may compensate for the temporary loss of a signal modality by switching to or increasing the use of an alternative, pre-existing modality. Communication in my study species involves acoustic and chemical cues, so I predicted that males lacking the ability to produce song would compensate by producing more attractive chemical cues. A female-response assay showed that females responded to chemical cues from both normal-winged and flatwing males, but did not exhibit a preference for either, indicating that flatwing males do not compensate for a lack of song with chemical cues.Further, on the Hawaiian islands, calling males are subject to lethal parasitism from an acoustically-orienting North American parasitoid fly, Ormia ochracea, and males in parasitized populations do not live as long as males from unparasitized populations. Given that flatwing males are unable to produce song and are thus protected from parasitism from O. ochracea, I predicted that flatwing males would have a greater average age than their normal-winged counterparts in the same population. Contrary to my predictions, flatwing males were not older than normal-winged males.

▼ An organism’s entire life history - the timing of development, reproduction, senescence and death - can depend on the nature of selection for reproductive age. The outcome of selection will depend both on the particular features of the selective environment and on the genetic architecture of life history in the population. The genetic architecture is highly complex and itself variable in response to selection. Various features of the architecture, including available genetic variation, pleiotropy, epistasis, intersexual genetic correlation, mitochondrial genomes and mito-nuclear interactions all play a role in determining the trajectory of life history evolution, and to interact with one another in doing so. Using eleven laboratory-adapted populations of Drosophila melanogaster that have been subject to controlled long-term selection for differing ages of reproduction, I undertook several experiments that help characterize how these aspects of genetic architecture have contributed to the life history of each population. These experiments combined assays of life history trait values in the standing genetic variation with manipulations of mutation accumulation rate and hybridization, to better understand the nature of selection shaping each life history. I found surprisingly strong positive pleiotropy between early reproduction and longevity, sufficient to maintain a stable ‘surplus’ life span lasting several weeks post-selection. Selection for extremely early reproduction, on the other hand, induced pleiotropic costs to reproductive traits in each sex in a trade-off with development time. Characterization of the intersexual genetic architecture for life span revealed it was largely sex-limited in nature, consistent with a history of intralocus sexual conflict affecting the trait. There was also evidence, however, that mutations affecting life span might interact to reinforce their effects, and that the resulting costs were manifested in both sexes. Selection on mitochondrial genomes in isolation did not contribute to evolution of age-specific reproduction, but mito-nuclear coadaptation was clearly important to its evolution for males in particular. Together, these results expand our understanding of how age-specific selection shapes life history in a popular model organism. They can be used to guide future research in this system and allow us to pose important questions to be tested in other species as well.

Cells that self-assemble into a toroidal cluster about the base of a conical pillar have been experimentally observed to spontaneously climb the conical pillar. In other cases, toroidal clusters do not climb the pillar but, instead, they may undergo localized thinning at one or more cross-sections around the circumference of the cluster.Assuming that cell cluster reorganization is due solely to surface diffusion, a mathematical model based on thermodynamics of an isothermal dissipative system is presented. The model shows that the cluster can reduce its surface area by climbing the conical pillar but at the expense of increasing its gravitational potential energy. As a result, the kinetics of the climb is affected by parameters that influence this energy competition such as the slope of the conical pillar or the surface mobility of the diffusing cells. The development of localized deformations in clusters that do not climb the conical pillar is examined by means of a linear stability analysis wherein a nominally uniform toroidal cluster has its shape perturbed by a periodic perturbation in its minor radius. Analysis reveals that the cluster is stable if the surface energy density is spatially uniform. However, if the surface energy density is allowed to vary from point to point around the circumference of the toroid, unstable configurations may develop. The stability of the cluster is observed to depend on its initial minor radius, the radius of the conical pillar and the wave number of the applied sinusoidal perturbation. A stability analysis of nominally cylindrical bodies which evolve in shape due to surface diffusion was then carried out to understand the role of nonlinearity in the stability criteria in such bodies. This analysis may serve as a basis for a future study of the stability of toroidal clusters or toroidal shapes beyond the range of linear behavior.

▼ This dissertation develops and tests theories on identity-based resource partitioning in the context of the German electricity market after deregulation in 1998. I apply insights from the recent theoretical development on organizational identity and pay special attention to the roles of audience heterogeneity which is observed through the lens of geography. Based on both theoretical arguments and field evidence, I detail the process of identity-based partitioning and explore three boundary conditions for sustaining an periphery identity oppositional to that of market leaders: intense cooperation among peripheral organizations, sufficient audience heterogeneity and short delays in enacting as well as in perceiving the periphery identity. I hypothesize that although increasing oppositional identities upon competitive release lead to resource partitioning, this effect varies substantially across audience segments embedded in geographical communities. Organizational founding rates increase with greater match between the peripheral identity and the values endorsed by the local community. I also propose while center organizations may absorb the majority of the released resources, competitive release leads to higher growth rates of peripheral organizations compared with those of the subsidiaries of the center ones. Combining the apparently opposing effects of the match between producer identity and audience tastes on founding rates and growth rates, I suggest that resource partitioning may occur both at the form level through new foundings and at the firm level through organizational growth, depending on the strength of the match. The theories and hypotheses are developed and tested using simulation experiments (chapter 2) and longitudinal quantitative data (chapter 3 and 4). This dissertation contributes to the theories on resource partitioning and organizational identity as well as to research on industrial evolution and sociology of market in general.

▼ Les plantes ont depuis longtemps fasciné les biologistes par leur capacité à former des espèces cryptiques, des hybrides entre des espèces distinctes, de grandes tailles de génomes stables, et une large variété de systèmes reproducteurs parmi les taxons qui ont conduit à l’actuelle biodiversité des plantes. Il y a plus de 450 millions d’années, les plantes vasculaires ont émergé et colonisé la terre. Rapidement, elles se sont dispersées pour explorer de nouveaux habitats et se sont diversifiées dans des environnements favorables pour former plus de 300 000 espèces vivantes. Une meilleure compréhension des forces évolutives passées qui ont mené aux morphologies, aux écologies, et aux diversités génétiques actuelles des plantes est essentielle pour prédire leur évolution, particulièrement dans le contexte des changements globaux. Ainsi, les objectifs principaux de cette thèse consistaient à étudier les relations phylogénétiques parmi les taxons de Botrychium et comment l’allopolyploïdie et l’alternance des systèmes reproducteurs ont mené à la spéciation de ces espèces. Dans un cadre multidisciplinaire, nous avons combiné la phylogénétique avec la génétique des populations et la cytométrie en flux pour produire des données cellulaires et moléculaires pertinentes pour l’exploration des mécanismes biologiques clefs prenant place à des échelles locales ou globales. Etant les fondements de notre projet, nous avons reconstruit la phylogénie chloroplastique du genre Botrychium basée sur un échantillonnage mondiale pour examiner les relations de parentés parmi les taxons diploïdes et les origines maternelles des allopolyploïdes. Dans une seconde étape, nous avons estimé les tailles de génome des Botrychium diploïdes et polyploïdes pour comparer les variations du contenu en ADN après l’allopolyploïdisation et entre les niveaux de ploïdie. Ensuite, nous avons utilisé le séquençage PacBio pour inférer une phylogénie moléculaire dans le but de révéler l’histoire évolutive des deux, les lignées maternelles et paternelles des allopolyploïdes, et d’établir l’échelle temporelle de leur héritage bi-parentale basée sur les estimations des temps de divergence. Travaillant à une échelle régionale et locale, nous avons génotypé des populations de B. lunaria des alpes en utilisant des variants enzymatiques co-dominants et des données de séquençage ddRAD pour caractériser le mode prédominant de reproduction ainsi que leur histoire démographique durant le dernier maximum glaciaire. Nous avons trouvé des résultats inattendus et des découvertes majeures pour la compréhension de la biologie des plantes vasculaires précoces. Pour la diversité spécifique elle-même, nous avons identifié treize nouveaux taxons potentiels et caractérisé la diversité exceptionnelle d’haplotypes survenant dans le complexe d’espèce Lunaria. De plus, nous avons présenté des évidences pour l’origine multiple de plusieurs taxons allopolyploïdes et révélé des cas incontestables de dipersion intercontinentale d’amérique du nord vers… Advisors/Committee Members: Jason (Dir.).

A great challenge that biology faces is in integrating phenomena from different scales. On the micro scale of the spectrum, we can measure subcellular processes, like gene expression and regulation. On the macro scale, we can measure species level variation, ecological interactions, and the like. The challenge biology faces is in following the causal threads that lead individuals, populations, and ultimately, species to the variation in traits that we see in nature. The idea that there are cascades of causality that reduce to a microscopic scale is often referred to as the Genotype to Phenotype map (Houle and Govindaraju 2010). The Genotype to Phenotype map is ultimately a problem of measurement; what do we need to measure at each scale of interest in order to understand and, more importantly, predict variation elsewhere on the spectrum? This thesis is focused on two parts of the genotype-phenotype spectrum. The first chapter focuses on the macro scale, specifically on how traits maintain stasis across species. Here we use Drosophila melanogaster wing shape as a model to test whether stasis is explained by constraint or by stabilizing selection. We test for constraint with an artificial selection experiment on wing shape. We then test for stabilizing selection by measuring flight differences among selected and unselected flies and by testing for mate preference. In the second chapter, I focus on the micro scale by describing a method to measure the spatial properties of gene expression patterns. Quantitative measures of gene expression currently focus on mutations in the genome and/or the magnitude of expression. This ignores the spatial components of gene activity that are critical in the formation of pattern and the maintenance of growth during development. I describe methods to measure the spatial characteristics of genes that form discrete and continuous patterns of expression. I then give three examples of the method by quantitatively disrupting three genes and estimating the effects on a discrete and a continuous expression pattern.

▼ In recent years, microRNAs (miRNAs) have been recognised as important genetic regulators of gene expression in Animals and Plants. They can potentially target a large fraction of the cellular transcriptome, having been shown to be important for diverse biological processes such as development, cell differentiation, proliferation and metabolism. The publication of the Human genome in 2001 marked the start of a great community effort to sequence a variety of other species. These data have great potential for comparative genomics, that can lead to better biological understanding. Some miRNA families are known to be highly conserved, across long evolutionary distances, many found in co-transcribed clusters across the genome. While these phenomena have been previously reported, a large-scale analysis of evolutionary patterns was still lacking. Furthermore, the rate at which new relevant data is being made available makes it challenging to keep up and many of the evolutionary studies performed before are now significantly out of date. This thesis describes a number of approaches taken to analyse miRNA datasets, harnessing the full potential of currently available data for comparative genomics. These were used, not only to revisit many of the notions in the field with a larger and updated dataset, but also to develop novel strategies that enable a coherent view of miRNA evolution at different evolutionary time-scales. A new tool, described within this thesis, was developed for large-scale, species independent miRNA mapping. An assessment of the evolution of the miRNA reper- toire across species was performed, together with detailed sequence conservation analysis and miRNA family clustering. Phylogenetic profile analysis uncovered in- teresting co-evolution between miRNAs and protein coding genes. The genomic organisation of miRNAs and their conservation across species was also studied, pro- viding detailed conserved synteny maps for miRNAs and proteins across more than 80 species. Finally, at the intra-specific level, I analysed the occurrence of single nucleotide polymorphisms affecting miRNA loci or their predicted target sites. All the tools built and integrated in this research were made available to the community and designed to be easily updated, making it easier to keep up with the data that is constantly being made available. Many aspects of miRNA biology are still being uncovered, and the ability to easily put these findings into an evolutionary context will potentially be useful for the community.

▼ Star formation in the Cam OB1 region is investigated. Star formation, in general, is considered in terms of three elements: a) the structural relationship between the parent molecular clouds and newly formed stars, b) the temporal evolution of the parent molecular clouds, and c) the probability of the occurrence of star formation. Star formation in Cam OB1 over the range in l and b considered in this work, is concentrated in the vicinity of Cam R1 and appears to have led to the formation of three distinct stellar groups: a) Group I. formed ~ 1 - 50 x 106 yr ago, and located spatially and kinematically between two CO complexes, b) Group II. formed ~ 1 - 3 x 106 yr ago. and coincident with one of the previously mentioned complexes, and c) Group III. the youngest group, formed ~ I - 20 x 104 yr ago, and located at the current point of intersection between the two complexes in (a). The mass function (MF) for Groups I and II is similar to the cloud mass function of the parent molecular clouds, i.e. a power-law with exponent α ~ 2. A similar analysis for the Group III stars and associated molecular clouds cannot be performed due to the relatively small numbers in both samples. The star forming efficiency (SFE) in all cases is ~ 1%. It is proposed that cloud-cloud collisions between the CO complexes in the region triggered the formation of Groups I and III, while Group II was produced by a shock induced by the radiation pressure and stellar winds from the stars in Group I. An analysis of the molecular cloud structure in Cam OB1 and the background Perseus arm also shows that the clouds in both regions are turbulent, and typical of clouds seen elsewhere in the Galaxy. However, the clouds in Cam OB1 show a large dispersion in the degree with which they are self-gravitating, with the larger, warmer clouds being gravitationally bound. The principal data set for this work comprises fully sampled [special characters omitted] observations of the western half of Cam OB1, which were obtained at the Center for Astrophysics during the winter of 1992-1993. These data have an effective resolution of 10', a velocity resolution of 0.65 km s-1, and a sensitivity of 0.115 K. High resolution (20") observations of the [special characters omitted] transition of the most active star forming region were obtained with the James Clerk Maxwell Telescope during the winter of 1994-1995. These observations led to the discovery of a second outflow. AFGL 490 – iki, associated with IRAS 03234+5843, in the immediate vicinity of the very well-studied molecular outflow AFGL 490. Additional observations of the [special characters omitted], taken with the 26m telescope at the Dominion Radio Astrophysical Observatory during the fall of 1994, did not reveal any such masering activity in the Cam OB1 region, but did lead to the discovery of a new maser, associated with IRAS 02455+6034. in the background Perseus arm.

Ce travail a pour objectif de proposer des méthodes pour améliorer la compréhension des processus d’évolution de la Loire moyenne sur quelques décennies. L’analyse des évolutions morphologiques est réalisée en découpant le secteur d’étude en tronçons géomorphologiquement homogènes. Une diminution de la pente et une réduction de la largeur de la bande active entre 1955 et 1996 sont observées. Suite à l’arrêt des extractions (1996),les ajustements se poursuivent de façon plus modérés.Des simplifications géométriques et hydrologiques sont ensuite introduites dans un modèle de transport solide unidimensionnel (RubarBE) afin d’être comparées aux résultats obtenus avec lag éométrie détaillée et la chronique de débit complète. La géométrie simplifiée permet une modélisation des évolutions du lit pertinente tout en réduisant le temps de calcul ; la simplification des chroniques de débit illustre la sensibilité des modèles numériques hydro-sédimentaires à l’hydrologie. Enfin, l’application des simplifications sur l’ensemble de la Loire moyenne sur la période 1996-2006 confirme les tendances observées par l’analyse des données.

This work deals with the development of methods that sought to assess channel changes of a long anthropogenised river over several decades. These methods are applied on the Middle Loire River (France). Channel changes are evaluated by dividing the study reach into geomorphically distinct river reaches. A narrowing of the active channel width and a decrease of the river bed slope were observed between 1955 and 1996. Since in stream gravel mining stopped (1996), river adjustments have continued at a slower rate. Simplified geometry and simplified hydrographs are then derived and introduced into a one dimensional sediment transport model (RubarBE). The simplified geometry allows pertinent calculation of the river bed evolution whilst reducing calculation time. The use of simplified hydrographs highlights the sensitivity of sediment transport modelling to hydrology. Finally, the application of the simplifications to the whole Loire Moyenne River confirms the general trend observed between 1996 and 2006.

▼ Understanding the origin of life requires understanding the origin of translation, which in turn, requires understanding the origin of the ribosome. Ribosomes are complex structures consisting of hundreds of thousands of atoms. Here, we describe how we organized ribosomal structures and information into a broad database, RiboZones. We also describe a new visualization web app, RiboVision. RiboZones and RiboVision are productivity tools that lower the learning curve for ribosomal research. RiboZones makes the ribosome more accessible. RiboVision especially helps create beautiful publication ready figures in a fraction of the labor and time previously required. It is only through the creation of RiboZones and RiboVision through which the rest of this dissertation became feasible. We constructed a high-quality sequence alignment of ribosomal sequences for both the LSU and the SSU rRNA. Each ribosomal sequence is complete, allowing detailed, low background statistics to be computed. The sequence alignment broadly samples the tree of life according to available data. The alignment was adjusted for maximum agreement with 3D superimpositions of multiple ribosomal structures. We defined a nucleotide-level definition of the common core of the ribosome, as the RNA that is present in 95% of the sequences in our alignment. Multiple versions of the common core were created, including the universal common core, the prokaryotic common core, and domain specific common cores. The definition allows statistics to be computed for various use-cases. For example, with RiboVision visualization technology, it is possible to see which helices are optional, in which of the three domains of life, and what the minimum helical length is for each helix. We discovered that ribosomal RNA grows mostly by helix extension and helix insertion. When a helix is inserted, it minimally perturbs the underlying helix. We call this pattern ‘insertion fingerprints’. Insertion fingerprints are found throughout the common core and the eukaryotic expansion segments. Insertion fingerprints were used to divide the ribosomal RNA into units called ancestral expansion segments (AES’s). AES’s make ideal structural, functional, and evolutionary units. The AES’s are arranged into the first complete experimentally testable model of ribosomal evolution. The model can be refined over time as new information is discovered.

▼ Integumentary pigmentation is a phenotype of fundamental importance to animals, with major impacts on survival and fitness. Thus, understanding the mechanisms underlying pigmentation can help illuminate general principles about how adaptive variation is generated and maintained in populations. Here, I present a dissertation that is aimed at understanding the developmental, regulatory, and genetic mechanisms that underlie variation in avian plumage color, and their evolutionary importance. In my first chapter, I addressed how the modular organization of plumage traits may impact their evolution. The production of color in developing feathers is a modular process, with several mechanisms combining to produce the complete feather phenotype. A modular trait organization is predicted to increase phenotypic evolvability by reducing negative pleiotropic interactions with functionally unrelated traits. Through phylogenetic comparative analysis, I show that separate mechanisms producing feather colors show independent, uncorrelated patterns of evolutionary change, consistent with their modular organization. My results show that developmental modularity can have detectable impacts on trait evolution. For my second chapter, I identified gene expression variation associated with melanin pigmentation in the Zebra Finch. I found differential expression of several functionally important genes that synthesize melanin. In addition, I found changes in expression in the signaling pathways that govern transcription of melanogenesis genes. These signaling pathways differ from those previously reported to drive major pigmentation differences, indicating that the regulation of melanogenesis is flexible in how it generates similar phenotypic outcomes. For my third chapter, I identified the genetic basis for loss of sexual dimorphism in a domestic color morph of Zebra Finch. With whole-genome sequencing, I found a major divergence peak between dimorphic and monomorphic finches containing the gene Norrie Disease Protein (NDP). NDP is a signaling molecule that regulates transcription of several melanogenesis genes, and is underexpressed when dimorphism is lost. Sexual dimorphism can be lost repeatedly and rapidly in many groups. My work shows that relatively simple genetic changes in the regulation of important signaling molecules can influence sexual dimorphism in a patch-specific manner, facilitating this rapid evolution.

▼ This thesis attempts to examine the use of pre-Darwinian evolutionary concepts in Victorian poetry by concentrating on the works of Tennyson, who gave fuller expression to them than any of his contemporaries. Works by other poets are examined for significant comparisons and contrasts with his; various works by Browning, Bailey, Arnold, and Bell Scott receive particular attention. The introduction distinguishes between Darwin's theory and pre-Darwinian evolutionary schemes, finding the latter to be characterized by the notions of teleology, progressivism, and vertical hierarchy. The historical development of evolutionism is traced from its origins in Romantic theories of the organic unity of nature, and the major varieties of considered positions on the subject available to a poet in the early nineteenth century are enumerated. Tennyson's early work is shown to develop from a basically static, non-evolutionary world-picture to a progressive one, making use of images of development drawn from embryology, astronomy, and reincarnation. The stages of composition of In Memoriam reveal the impact of Lyell, who emphasized the struggle for existence and necessary extinction, and later of Chambers, who proposed a concept of the progressive transformation of species. It is proposed that Tennyson found in Chambers' theory a way of transcending the bleak world-picture offered by Lyell, by uniting it with his conception of a spiritual reality behind (not immanent in) the material world. The final arrangement of In Memoriam develops the idea of evolution as the progress of the natural world toward the spiritual, a position analogous to a number of poetic and philosophical trends in the early nineteenth century. This process of evolution can be voluntarily aided by "typing" the higher, emergent forms in one's own life. Expanding on this notion, Tennyson's poetry of the late 1340's and 1350's demands the conscious participation of human society in the shaping of a higher being. With this development, Tennyson's philosophy of evolution is substantially complete. His later works reveal a gradual attenuation of his immediate hopes for the process, pushing the improvement of the species into the increasingly distant future, but remaining consistently meliorist; otherwise, his principle continues to be the one set forth in In Memoriam. The study concludes with a brief examination of Darwin's influence on later poets, showing it to have been generally confused and the result of misinterpretation.

▼ Bipedality is a distinctive locomotor characteristic of some of the most noteworthy animals of all time, including dinosaurs and humans. However, the evolution of a bipedal locomotor mode is poorly understood in reptiles. It has been repeatedly hypothesised that a facultative locomotor mode, where an animal moves both bipedally and quadrupedally under different conditions, forms an intermediate stage in the evolution of obligate bipedality. I demonstrate that the evidence supporting this hypothesis is lacking, recovering facultative bipedality as an intermediate stage only once in multiple independent evolutions of bipedality, under two different topologies. In order to better understand facultative bipedality and the associated anatomies, I performed multiple studies into the ecomorphology and evolution of this behaviour in a modern clade: Lepidosauria. Linear morphometric studies accounting for variation in body size indicate that forelimb segment lengths across locomotor modes do not differ for lepidosaurs of the same size, but that distal hindlimbs segments differ greatly, contrasting with historical tropes. Using 3D landmark-based geometric morphometrics, I demonstrate that arboreal and facultatively bipedal species share many characteristics in the bony elements of the pelvis, including a straight-to-concave iliac blade and large ischial base. These shared anatomies are functionally qualified based on anatomical studies of lepidosaur pelvic girdle myology, and indicate a similarity in mechanical demands of both arboreality and facultative bipedality. Finally, I tested for the correlated evolution of facultative bipedality with substrate preference in a derived clade of squamates: Episquamata. Findings suggest that there is no correlation between substrate and a facultative locomotor mode, instead indicating that facultative bipedality is an exaptation of anatomies associated with vertically diverse environments. This echoes the evolution facultative bipedality in hominin, macropods and rodents, and is distinct from any current hypotheses concerning the evolution of archosaurian bipedality.
