The Impacts Of Environment And Host Evolutionary Relationships On Lemur Microbiota, Rachel B. Burten

Doctoral Dissertations

Recent studies have shown that the mammal microbiome is modified by environmental conditions, and that reduced microbiome functionality is associated with host health issues. Microbiome data in wild and captive primate populations can therefore be used to assess their health as they encounter a variety of environments. Comparative studies of the microbiome can also inform disease ecology, conservation, and captive management strategies tailored to different primate species. Therefore, this study examines how the hair, oral, and gut microbiota of nine wild and captive lemur species are determined by host phylogenetic relationships and host environment. I found that host species identity …

Diversity And Evolution Of Human Eccrine Sweat Gland Density, Andrew W. Best

Doctoral Dissertations

Human eccrine density is highly derived. However, little is known about contemporary variation in this trait, what shapes it, and how it influences heat dissipation. This project explores 3 questions: 1) Is variation in functional eccrine density (FED) explained by childhood climate? 2) Is this variation patterned by geographic ancestry? 3) Is variation in FED associated with differences in heat dissipation capacity? We measured FED and sweat production in 6 body areas via pharmacological stimulation and impressions of sweating skin in 72 participants. Childhood climate variables were taken from the WorldClim database and geographic ancestry was estimated with 23andMe tests. …

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 …

De-Coding The Impact Of Evolved Changes In Gene Expression And Cellular Phenotype On Primate Evolution, Trisha Zintel

Doctoral Dissertations

The goal of the dissertation work outlined here was to investigate the influence of proximal processes contributing to evolutionary differences in phenotypes among primate species. There are numerous previous comparative analyses of gene expression between primate brain regions. However, primate brain tissue samples are relatively rare, and my results have contributed to the pre-existing data on more well-studied primates (i.e. humans, chimpanzees, macaques, marmosets) as well as produced information on more rarely-studied primates (i.e. patas monkey, siamang, spider monkey). Additionally, the primary visual cortex has not previously been as extensively studied at the level of gene expression as other brain …

Panel 3 Paper 3.2: Nature, Agriculture And Rural Resilience: Interdependencies Between Natural Protected Areas And Rural Landscapes In Satoyama/Satoumi In Japan, Maya N. Ishizawa

ISCCL Scientific Symposia and Annual General Meetings // Symposiums scientifiques et assemblées générales annuelles de l'ISCCL // Simposios científicos yy las Asambleas Generales Anuales

The Capacity Building Workshops on Nature-Culture Linkages in Heritage Conservation (CBWNCL), held at the University of Tsukuba in Japan, gather Asia-Pacific heritage professionals with the aim of creating a platform of mutual-learning and exchange between the culture and nature sectors. In the first workshop on Agricultural Landscapes, from 14 case studies, 5 showed natural protected areas in tense relations with their rural landscape surroundings. However, these agricultural landscapes are essential for protecting natural values, as they form part of their larger ecosystems. In the second workshop on Sacred Landscapes, from 16 case studies, 5 case studies were also …

Were Neandertal Humeri Adapted For Spear Thrusting Or Throwing? A Finite Element Study, Michael Anthony Berthaume

Masters Theses

An ongoing debate concerning Neandertal ecology is whether or not they utilized long range weaponry. The anteroposteriorly expanded cross-section of Neandertal humeri have led some to argue they thrusted their weapons, while the rounder cross-section of Late Upper Paleolithic modern human humeri suggests they threw their weapons. We test the hypothesis that Neandertal humeri were built to resist strains engendered by thrusting rather than throwing using finite element models of one Neandertal, one Early Upper Paleolithic (EUP) human and three recent human humeri, representing a range of cross-sectional shapes and sizes. Electromyography and kinematic data and articulated skeletons were used …

Loss Of Cell Surface Agal During Catarrhine Evolution: Possible Implications For The Evolution Of Resistance To Viral Infections And For Oligocene Lineage Divergence, Idalia Aracely Rodriguez

Doctoral Dissertations

The divergence of the two superfamilies belonging to the Infraorder Catarrhini –Cercopithecoidea (Old World monkeys) and Hominoidea (apes, including humans) – is generally assumed to have occurred during the Oligocene, between 38 and 20 million years ago. Genetic studies indicate that this time period was one of active genetic evolution under strong purifying selection for catarrhine primates. This includes selective pressures on the glycoprotein galactosyltransferase 1 (GGTA1) gene and subsequent inactivation “clocked” at approximately 28 ma, possibly prior to the Cercopithecoidea/Hominoidea split. The GGTA1 gene codes for an a1,3 galactosyltransferase (GT) enzyme that synthesizes a terminal disaccharide, …

Youth Participation In Changing Food Systems: Toward Food Justice Youth Development, Krista Harper, Catherine Sands, Diego Angarita, Molly Totman

Krista M. Harper

We present results from a youth participatory action research (YPAR) project in which young people from Holyoke studied the school food system in order to make positive interventions in their school district. We used the Photovoice research method, placing cameras in the hands of youth so that they themselves could document and discuss their concerns and perspectives (Wang, et al., 1996). The research was designed to gain insight about the students’ knowledge of food, nutrition, and community food systems. The research also illuminated students’ impressions of public policy, active citizenship, and community building that have arisen out of food justice …

Biochar & Aquaponics: Jonathan Bates

http://www.youtube.com/watch?v=9c21drA2KS4

Jonathan will present his experience using biochar as a powerful growing medium in aquaponic systems. Aquaponics being the culturing of fish and plants together ecologically in closed systems (the merging of aquaculture and hydroponics). Biochar grow media benefits aquaponic systems in multiple ways, including its light weight, local sourcing, bio-chemical qualities, ecological nature, and affordable price. Through pictures and discussion he will show how his experiment has faired, and offer ideas for economic opportunities of aquaponic biochar in the Northeast.

Runx2 Tandem Repeats And The Evolution Of Facial Length In Placental Mammals, Jason M. Kamilar, Marie A. Pointer, Vera Warmuth, Stephen G.B. Chester, Frédéric Delsuc, Nicholas I. Mundy, Robert J. Asher, Brenda J. Bradley

Anthropology Department Faculty Publication Series

Background

When simple sequence repeats are integrated into functional genes, they can potentially act as evolutionary ‘tuning knobs’, supplying abundant genetic variation with minimal risk of pleiotropic deleterious effects. The genetic basis of variation in facial shape and length represents a possible example of this phenomenon. Runt-related transcription factor 2 (RUNX2), which is involved in osteoblast differentiation, contains a functionally-important tandem repeat of glutamine and alanine amino acids. The ratio of glutamines to alanines (the QA ratio) in this protein seemingly influences the regulation of bone development. Notably, in domestic breeds of dog, and in carnivorans in general, the ratio …

The Climatic Niche Diversity Of Malagasy Primates: A Phylogenetic Approach, Jason M. Kamilar, Kathleen M. Muldoon

Anthropology Department Faculty Publication Series

Background

Numerous researchers have posited that there should be a strong negative relationship between the evolutionary distance among species and their ecological similarity. Alternative evidence suggests that members of adaptive radiations should display no relationship between divergence time and ecological similarity because rapid evolution results in near-simultaneous speciation early in the clade's history. In this paper, we performed the first investigation of ecological diversity in a phylogenetic context using a mammalian adaptive radiation, the Malagasy primates.

Methodology/Principal Findings

We collected data for 43 extant species including: 1) 1064 species by locality samples, 2) GIS climate data for each sampling locality, …

Bolivia's Coca Headache: The Agroyungas Program, Inflation, Campesinos, Coca And Capitalism In Bolivia, John D. Roberts

Masters Theses 1911 - February 2014

Bolivia in the 1980s was wracked by monetary inflation approaching levels of the German Weimar Republic. Immediately following this time of great financial crisis in Bolivia, the U.N. founded a project through the U.N.D.P. to encourage peasant farmers in Bolivia to switch from growing coca (the plant used manufacture cocaine) to growing other cash crops for market. This crop substitution and development program, called the Agroyungas Project, lasted from 1985 to 1991 and is the focus of this study. While many U.N. pundits and journalists considered the program’s initial small successes promising, it has been considered since its conclusion to …

A Photovoice Participatory Evaluation Of A School Gardening Program Through The Eyes Of Fifth Graders, Catherine Sands, Krista Harper, Lee Ellen Reed, Maggie Shar

Anthropology Department Faculty Publication Series

In the springtime, fifth grade students at the Williamsburg Elementary School in rural Western Massachusetts ask to snack on sorrel and chives from the school garden, between planting potatoes and building a shade structure for their outdoor classroom. They are members of the first cohort of the curriculum-integrated program initiated by Fertile Ground, a grassroots organization in western Massachusetts. The children’s delight in the fresh greens they have grown marks a national phenomenon: the farm-to-school movement. With limited resources, parents, teachers, students, administrators, and community activists are developing inroads to better school food and food education, by constructing school teaching …

Forever Young: Upon Reading Growing Young By Ashley Montagu, Raymond Coppinger, Charles Smith

Charles Kay Smith

We argue that the evolutionary process of neoteny -- the natural selection of regulatory gene mutations that retain a youthful ontogenetic system of physiological and behavioral characteristics, and thus never activates the full species-specific features of the ancestors’ adulthood. The resulting new behavio-morph retains infant/young features throughout ontogeny and never displays the adult behavior or physiology of the adult ancestor. This kind of neotenic adulthood defines the human character. We not only inherit our ancestors’ youthful anatomy and physiology but the ancestors’ youthful motivations and proclivities such as docility and social dependency, curiosity and learning as well. We retain our …
