The Importance Of Fallback Foods In Primate Ecology And Evolution, Paul J. Constantino, Barth W. Wright

Biological Sciences Faculty Research

The role of fallback foods in shaping primate ranging, socioecology, and morphology has recently become a topic of particular interest to biological anthropologists. Although the use of fallback resources has been noted in the ecological and primatological literature for a number of decades, few attempts have been made to define fallback foods or to explore the utility of this concept for primate evolutionary biologists and ecologists. As a preface to this special issue of the American Journal of Physical Anthropology devoted to the topic of fallback foods in primate ecology and evolution, we discuss the development and use of the …

Assessing Animal Welfare: Different Philosophies, Different Scientific Approaches, David Fraser

Assessment of Animal Welfare Collection

Attempts to improve animal welfare have commonly centered around three broad objectives: (1) to ensure good physical health and functioning of animals, (2) to minimize unpleasant ‘‘affective states’’ (pain, fear, etc.) and to allow animals normal pleasures, and (3) to allow animals to develop and live in ways that are natural for the species. Each of these objectives has given rise to scientific approaches for assessing animal welfare. An emphasis on health and functioning has led to assessment methods based on rates of disease, injury, mortality, and reproductive success. An emphasis on affective states has led to assessment methods based …

Genome 10k: A Proposal To Obtain Whole-Genome Sequence For 10 000 Vertebrate Species, Tony Gamble, Genome 10k Community Of Scientists

Biological Sciences Faculty Research and Publications

The human genome project has been recently complemented by whole-genome assessment sequence of 32 mammals and 24 nonmammalian vertebrate species suitable for comparative genomic analyses. Here we anticipate a precipitous drop in costs and increase in sequencing efficiency, with concomitant development of improved annotation technology and, therefore, propose to create a collection of tissue and DNA specimens for 10 000 vertebrate species specifically designated for whole-genome sequencing in the very near future. For this purpose, we, the Genome 10K Community of Scientists (G₁₀KCOS), will assemble and allocate a biospecimen collection of some 16 203 representative vertebrate species spanning …

IAA Reports—Monograph Series of the Israel Antiquities Authority

This is the first of two volumes documenting the IAA excavations at this site in the ‘Akko Plain. This volume presents the early periods, including occupation during the Pre-Pottery Neolithic to the Chalcolithic periods, with significant pottery and flint finds, then a substantial EB IA settlement, an Intermediate Bronze Age settlement and an ephemeral presence in the Late Bronze Age, as evidenced by the pottery finds. The site lay in ruins throughout the Iron Age until an extensive resettlement in the Persian period and a small Hellenistic-period presence.

Grey To Green: The Wolf As Culture And Profit In Mongolia And The Importance Of Its Survival, Samuel Legrys

Independent Study Project (ISP) Collection

“The king of this place could be Bear; it can capture and eat anything, even roe deer and moose. But I think sometimes Bear is eaten by Wolf, working as a pack. It means that Wolf is the king of the king” – Joogdernamjil, Dadal Hunter The grey wolf is a key figure in Mongolian culture, representing not only the male ancestor behind the bloodline of Chinggis Khaan, but also the messenger of heaven, sent to punish those who disrespect the spirit masters of the land. Countryside herders and UB businessmen alike honor the wolf as a spiritually powerful animal, …

Genetic Population Structure Analysis In New Hampshire Reveals Eastern European Ancestry, Chantel D. Sloan, Angeline D. Andrew, Eric J. Duell, Scott M. Williams, Margaret R. Karagas, Jason H. Moore

Dartmouth Scholarship

Genetic structure due to ancestry has been well documented among many divergent human populations. However, the ability to associate ancestry with genetic substructure without using supervised clustering has not been explored in more presumably homogeneous and admixed US populations. The goal of this study was to determine if genetic structure could be detected in a United States population from a single state where the individuals have mixed European ancestry. Using Bayesian clustering with a set of 960 single nucleotide polymorphisms (SNPs) we found evidence of population stratification in 864 individuals from New Hampshire that can be used to differentiate the …

An Examination Of Chimpanzee Use In Human Cancer Research, Jarrod Bailey

Laboratory Experiments Collection

Advocates of chimpanzee research claim the genetic similarity of humans and chimpanzees make them an indispensable research tool to combat human diseases. Given that cancer is a leading cause of human death worldwide, one might expect that if chimpanzees were needed for, or were productive in, cancer research, then they would have been widely used. This comprehensive literature analysis reveals that chimpanzees have scarcely been used in any form of cancer research, and that chimpanzee tumours are extremely rare and biologically different from human cancers. Often, chimpanzee citations described peripheral use of chimpanzee cells and genetic material in predominantly human …

Sibship Reconstruction Demonstrates The Extremely Low Effective Population Size Of Striped Bass Morone Saxatilis In The Santee-Cooper System, South Carolina, Usa, Jin-Xian Liu, Bert Ely

Faculty Publications

For organisms with great fecundity and high mortality in early life stages, such as shellfish or fishes, the need to match reproductive activity with environmental conditions conducive to spawning, fertilization, larval development and recruitment may result in extreme variance in reproductive success among individuals. The main objective of this study was to investigate evidence of large variance in the reproductive success of the striped bass Morone saxatilis in the Santee-Cooper system, South Carolina, USA. Seven microsatellite loci were analysed in 603 recruits representing three yearly cohorts from 1992 to 1994, and a group analysis was performed to identify full-sib families. …

Stable Carbon Isotope Evidence Of Ancient Maya Agriculture At Tikal, Guatemala, Richard Lee Burnett

Theses and Dissertations

Stable carbon isotope analyses of the humin fraction of the soil organic matter were conducted on more than 160 soil profiles from Tikal, Guatemala. The profiles were collected from near areas associated with the earthworks of Tikal; an ancient ditch and parapet construction hypothesized to have formed ancient boundaries of the polity. In addition to the isotope analyses, the physical and chemical characteristics of the horizons were determined. Maize, a C4 plant, formed an integral part of the ancient Maya diet and is the only known C4 plant cultivated by the Maya. Prior to and subsequent to the ancient Maya …

Phylogeography Of The North American Red Fox: Vicariance In Pleistocene Forest Refugia, Keith B. Aubry, Mark J. Statham, Benjamin N. Sacks, John D. Perrine, Samantha M. Wisely

Biological Sciences

Fossil, archaeological, and morphometric data suggest that indigenous red foxes in North America were derived from vicariance in two disjunct refugia during the last glaciation: one in Beringia and one in the contiguous USA. To test this hypothesis, we conducted a phylogeographical analysis of the North American red fox within its presettlement range. We sequenced portions of the mitochondrial cytochrome b (354 bp) gene and D-loop (342 bp) from 220 historical red fox specimens. Phylogenetic analysis of the cytochrome b gene produced two clades that diverged c. 400 000 years before present (bp): a Holarctic and a Nearctic clade. …

Cultural Responses To Climate Change In The Holocene, Richard Prentice

Anthós

Variable Holocene climate conditions have caused cultures to thrive, adapt or fail. The invention of agriculture and the domestication of plants and animals allowed sedentary societies to develop and are the result of the climate becoming warmer after the last glaciation. The subsequent cooling of the Younger Dryas forced humans to concentrate into geographic areas that had an abundant water supply and ultimately favorable conditions for the use of agriculture and widespread domestication of plants and animals. Population densities would have reached a threshold and forced a return to foraging, however the end of the Younger Dryas at 10,000 BP …

Diversity, Distribution And Role Of Wild Crucifers In Major Cabbage And Kale Growing Areas Of Kenya, R. Kahuthia-Gathu, B. Löhr, H. M. Poehling, P. K. Mbugua

All Peer-Reviewed Publications

An investigation of the diversity and distribution of wild crucifer species and their importance for cultivated crucifers was conducted during 2005 and 2006 in the highland and mid-altitude semi-arid areas of Kenya. Thirteen species of wild crucifers in nine genera were recorded: Raphanus raphanistrum, Erucastrum arabicum, Sisymbrium officinale, Crambe kilimandscharica, Capsella bursa-pastoris, Rorippa nudiuscula, Ro. micrantha, Ro. microphylla, Lepidium bonariense, Coronopus didymus, Brassica rapa, B. juncea and an unidentified Brassica species. Highland areas had significantly higher species diversity and species richness than mid-altitude semi-arid areas. Species richness, diversity and evenness varied with season and location. Raphanus raphanistrum was the dominant …

Contribution Of Candida Albicans To The Synthesis Of The Volatile Organic Compound Ethanol In Putrefied Bodies, Chelsey Mozingo

Honors Theses

This experiment sought to determine if Candida albicans contributed to the production of the volatile organic compound ethanol in decomposing beef livers. The results this experiment proved to be inconclusive. This experiment showed no correlation between the amount the presence of Candida albicans and the production of the volatile organic compound ethanol based on the standard addition method. This may be indicative that VOC analysis is not an appropriate method for determining time of death based on a quantitative analysis of volatile organic compounds. However, the experimental design most likely needs be altered to accommodate a more accurate method of …

Bougneres, G. R. Chandak, P. Dasgupta, G. D. Smith, P. T. Ellison, T. E. Forrester, Scott F. Gilbert, E. Jablonka, H. Kaplan, A. M. Prentice, S. J. Simpson, R. Uauy, M. J. West-Eberhard

Biology Faculty Works

The Lancet has rightly drawn attention to the goals of reducing the burden of maternal and childhood undernutrition,¹ focusing mainly on short-term outcomes such as infant survival and stunting.² However, the longer term effects on adult health³ of a poor start to life suggest a further perspective. Developmental effects have been viewed traditionally in the context of major disruptions such as caused by teratogens, prematurity and growth retardation, but there is increasing appreciation of the role of developmental plasticity, which provides individuals with the flexibility to adjust their trajectory of development to match their environment.

Microscopic hair identification provides a diagnostic tool for identifying mammalian hair and has broad applications in the field of wildlife damage management. Hair collected from scent stations can provide presence confirmation and population density estimates on carnivores and ungulates, while hairs extracted from scats …

Investigations Into Earthworm Control On Airports, T. Seamans, G. Bernhardt, D. Steyer

Wildlife Damage Management Conference

Earthworms, though generally considered beneficial for soil conditioning, can become a hazard at airports. When found in large numbers on runways or taxiways after heavy rainfall, they create slippery conditions for aircraft rolling over them. Additionally, earthworms attract birds, especially gulls, thereby increasing the risk of bird strikes to aircraft that are landing or taking off. For example, during a 35-minute period on 3 September 2004 at Calgary International Airport (YYC), a B737 of Westjet and an A319 of Air Canada aborted takeoffs after multiple strikes with gulls attracted to the runways to feed on earthworms. The B737 had strikes …

Retrospective Barrier Placements For A Skunk Rabies Epizootic In Nw Wyoming, C. Ramey, K. Mills, R. Mclean, R. Engeman, J. Fischer

Wildlife Damage Management Conference

Striped skunks (Mephitis mephitis) are the most important reservoir of rabies on the Great Plains. In August, 1988 a skunk rabies epizootic proceeded from the "index case" west of Cowley, WY. By 1991, epizootic had reached nearly all areas in the Shoshone River Basin (SRB), and it ended in 1993. This area and the remainder of the SRB had been previously considered rabies-free. The USDA's Wildlife Services (WS) cooperated with state and local officials in a rabies monitoring and control program starting in 1990. Using information from the literature, signs, tracks, and radio-telemetry of normal and rabid skunks, …

Animal Behaviour, Animal Welfare And The Scientific Study Of Affect, David Fraser

Emotion Collection

Many questions about animal welfare involve the affective states of animals (pain, fear, distress) and people look to science to clarify these issues as a basis for practices, policies and standards. However, the science of the mid twentieth century tended to be silent on matters of animal affect for both philosophical and methodological reasons. Philosophically, under the influence of Positivism many scientists considered that the affective states of animals fall outside the scope of science. Certain methodological features of the research also favoured explanations that did not involve affect. The features included the tendency to rely on abstract, quantitative measures …

Molecular Analysis Of The Genetic Heterogeneity Between Primary And Recurrent Glioblastoma, Anushi Shah

Renée Crown University Honors Thesis Projects - All

Introduction: Glioblastoma multiforme (GBM) is one of the deadliest forms of brain cancer, and affects more than 18,000 new cases each year in the United States alone. The current standard of treatment for GBM includes surgical removal of the tumor, along with radiation and chemotherapy. Despite these treatments, recurrence of GBM is extremely common, and once it recurs, the life expectancy is measured in weeks or months. One of the reasons for the deadly nature of the recurrent GBM is thought to be selection for therapy-resistant tumor cells. In this project, we sought to characterize the molecular changes in recurrent …

The Evolution Of Skull Form And Function Among The East African Cichlids Of Lakes Malawi, Victoria, And Tanganyika, Alyssa Mcintyre

Renée Crown University Honors Thesis Projects - All

An animal’s skeletal and muscular structures form a biological machine capable of interacting with its environment. When anatomical form changes the resulting modification in biomechanical function can allow it to occupy a new ecological niche. The cichlid fishes of the major East African Rift Lakes have been frequently regarded as one of the best know examples of adaptive radiations that have produced a large variety of skull shapes in an unusually short span of evolutionary time that has permitted the use of an extremely wide variety of feeding niches. I studied the anatomical diversity of this incredible lineage by dissecting …

Alternative Futures 2030: Ogden Valley, Louis Alan Hurst

The present project analyzes the taphonomic processes and variables involved in the decomposition and desiccation of animal remains in an arid/hyper-arid environment. The study and the derived data will assist in determining postmortem intervals for remains in modern contexts, inform judgments made regarding mortuary habits and techniques in archaeological contexts, and will improve our knowledge regarding taphonomic processes. Manner of deposition, the depositional surface/medium and arid-climate specific variables (temperature, water, insect activity, weathering, pH levels, and soil characteristics) were examined in this study. Reported observations are limited to the first ten months following death from early December through early October …

Greater Sage-Grouse And Energy Development In Northeastern Utah: Implications For Management, Leah Suzanne Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Concern regarding the effect of energy development on greater sage-grouse (Centrocercus urophasianus) is increasing as the search for fossil fuel intensifies. Sage-grouse may be especially sensitive to energy development because they require large, diverse areas of sagebrush (Artemisia spp.) habitat to complete their life cycle. Additionally, the network of pipelines, roads, and wells required by energy development may fragment sagebrush habitat isolating populations and contributing to genetic drift, inbreeding, local extinction, or rapid divergence.

Seep Ridge, located in northeastern Utah, is one area where sage-grouse habitat and energy development plans overlap. Approved leases call for the construction …
