Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos
Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos
Masters Theses
Primate hair is both a substrate upon which essential social interactions occur and an important host-pathogen interface. As commensal microbes provide important immune functions for their hosts, understanding the microbial diversity in primate hair could provide insight into primate immunity and disease transmission. While studies of human hair and skin microbiomes show differences in microbial communities across body regions, little is known about the nonhuman primate hair microbiome. In this study, we collected hair samples (n=159) from 8 body regions across 12 nonhuman primate species housed at 3 US institutions to examine 1) the diversity and composition of the primate …
The Evolution Of Sex Differences In Mandrills (Mandrillus Sphinx): Micro- And Macroevolution, Jerred Klint Schafer
The Evolution Of Sex Differences In Mandrills (Mandrillus Sphinx): Micro- And Macroevolution, Jerred Klint Schafer
Legacy Theses & Dissertations (2009 - 2024)
Primates show diverse patterns of adaptive color and body size dimorphism produced by inter- and intrasexual selection. However, the specific microevolutionary processes that produce variation in secondary sexual characteristics remain largely unexplored in primates. Furthermore, sexual conflict theory predicts that female and male secondary sexual traits can coevolve in an antagonistic manner and promote speciation. This dissertation explores the microevolution of secondary sexual characteristics in mandrills (Mandrillus sphinx) and the macroevolution of these characters in anthropoid primates. I address the microevolution of mandrill facial coloration and body mass by estimating the heritability, phenotypic selection, and genetic evolution of these traits …
Colobinae Evolution: Using Gis To Map The Distribution Of Leaf Monkeys Across Southeast Asia Over Time, Marie Vergamini, Christina Mcgrath, Lisa M. Day
Colobinae Evolution: Using Gis To Map The Distribution Of Leaf Monkeys Across Southeast Asia Over Time, Marie Vergamini, Christina Mcgrath, Lisa M. Day
Graduate Research Posters
The Colobinae, or leaf monkeys, are distributed geographically across Africa and Asia. Colobinae are specialized arborealists and leaf eaters with sacculated stomachs, sheering teeth, reduced thumbs, and very mobile shoulders. Colobinae diverged ~10.9 million year ago (Ma) from the Cercopithecidae in Africa, and Asian colobines appear in the fossil record in the late Miocene ~8.5 Ma. However, an incomplete fossil record means little is known about the evolutionary pressures that led to Asian colobine migration and diversification. Here, we use recent fossil discoveries and geospatial information to develop hypotheses about how geographic barriers played direct roles in Asian colobine evolution. …
Sacral Morphology Of Prehensile-Tailed Primates In Relation To Biomechanical Loading, Hannah Grace Showalter
Sacral Morphology Of Prehensile-Tailed Primates In Relation To Biomechanical Loading, Hannah Grace Showalter
Graduate Theses and Dissertations
The few available comparative studies of prehensile tail anatomy in primates have established that several features of the caudal vertebrae are associated with adaptation to the increased loading of the tail during prehension. Given that the caudal vertebrae are anchored to the sacrum, it stands to reason that sacral morphology should also covary with tail prehensility. Convergent evolution of prehension in ateline and cebine primates and clear variation in the use of tails among taxa raises questions not only of how sacral morphology differs between prehensile and non-prehensile taxa, but whether different prehensile-tailed taxa evolved the same solutions to the …
Trees For The Primates: A Community-Based Assessment Of Crowned Lemur (Eulemur Coronatus) Habitat Preferences And Conservation In Northern Madagascar, Fernando Mario Mercado Malabet
Trees For The Primates: A Community-Based Assessment Of Crowned Lemur (Eulemur Coronatus) Habitat Preferences And Conservation In Northern Madagascar, Fernando Mario Mercado Malabet
Electronic Thesis and Dissertation Repository
As a result of the continuous loss of forest habitats in Madagascar, forest fragments that exhibit a high degree of degradation and are strongly embedded on the livelihood needs of rural Malagasy people are increasingly being considered as the focus of conservation management operations. This new type of protected areas, based on the IUCN’s Category V management model for conservation action, promises a social-ecologically balanced method of environmental intervention that seeks to protect ecological communities while promoting sustainable socioeconomic systems. However, due to the poor ecological quality and immense level of anthropogenic influence in the type of forests that serves …
Do Non-Human Primates Have Gender?, Aaron Pelchat
Do Non-Human Primates Have Gender?, Aaron Pelchat
Senior Honors Projects
As activism for trans rights and gender equality becomes ever more prevalent in the current American political discourse, so too has there been a rise in questions about gender. Are sexuality and gender linked? Aren’t there only two genders? What is the difference between gender and sex? Is there a difference? How does one DO gender? Isn’t gender just something you are born with? Helping the public understand these questions is important to transgender and gender non-conforming individuals in a time when more people are “coming out of the closet” and identifying as genders other than cisgender. As an anthropologist, …
3-D Morphometric Analysis Of The Primate Elbow Joint, Seth Brockman Boren
3-D Morphometric Analysis Of The Primate Elbow Joint, Seth Brockman Boren
Graduate Theses and Dissertations
Large body size requires limb joints capable of supporting said weight, and a species exhibiting sexual size dimorphism may necessitate joint size differences between the sexes of the species. If habitual behavior differs with body size, one may expect to see significant variation in joint morphology between species and the sexes within species. The following analysis tests two hypotheses: (1) that significant differences in joint size between males and females correlate with the magnitude of sexual dimorphism and (2) that there is significant interspecific variance in joint shape between males and females of the same species. The first hypothesis is …
Digital Baboon: Curating 30 Years Of Primatology Research Data, Cynthia Hudson-Vitale, Jennifer Moore
Digital Baboon: Curating 30 Years Of Primatology Research Data, Cynthia Hudson-Vitale, Jennifer Moore
University Libraries Presentations
Many digital data curators will agree that making digital storage, online platform, digitization best practices, and metadata schema choices is a complicated process, even for a simple database. Curating a project that encompasses tooth casts, palm prints, field sheets, videos, images, and a database assembled over a thirty-year period extends those challenges, but also creates an opportunity to preserve and share an irreplaceable contribution to research. Librarians at Washington University in St. Louis are currently working with Dr. Jane Phillips-Conroy, Professor of Physical Anthropology; Anatomy and Neurobiology, to digitally curate this heterogeneous mix of physical and digital data. Dr. Phillips-Conroy’s …
Coping With Forest Fragmentation: A Comparison Of Colobus Angolensis Palliatus Dietary Diversity And Behavioral Plasticity In The East Sagara Forest, Tanzania., Noah T. Dunham
Honors Projects
Habitat destruction and forest fragmentation are perhaps the largest threats to primate species around the world. While national parks, games reserves, and primate sanctuaries are instrumental in primate conservation, research suggests that some non-governmentally protected forest fragments may also serve as viable habitats for primates. Of course not all primates respond to fragmentation in the same way, but a species’ ability to survive in a fragment relates to 1) home range size 2) degree of frugivory 3) dietary flexibility and behavioral plasticity and 4) ability to utilize matrix habitats. Here I describe these variables in relation to black and white …
