Allomaternal Care By Conspecifics Impacts Activity Budgets Of Colobus Guereza Mothers, Dominique L. Raboin

Theses and Dissertations

In primate societies, caring for infants involves nursing, protection, provisioning, and carrying - all energetically taxing states for mothers. The cost of holding and carrying clinging infants often constrains mothers from moving and traveling, potentially reducing their food and energy intake. Alternatively, when an infant is physically separated from their mother they are at risk of predation from birds of prey or other large mammals. This requires a high level of vigilance from mothers, often further deterring them from acquiring the food and energy that they need. Allomaternal care (AMC) is hypothesized to provide mothers with a way to safely …

A New Estimate For Neanderthal Energy Expenditure, Stephen J. Venner

Theses and Dissertations

This study presents a new estimate for Neanderthal total energy expenditure through the use of a constrained energy model. The new estimates for Neanderthal are considered within the context of some recent analyses investigating Neanderthal life history traits, genetics, and the archaeological record.

Do Osteon Morphotypes Identified In The Mid-Diaphysis Of Human Femurs Indicate The Same Torsional Load History As Chimpanzees?, Bailey A G Colohan

Theses and Dissertations

Skedros’s (2009) osteon morphotype scoring (MTS) scheme is employed to identify if humans have the same torsional load-bearing history as chimpanzees at the femoral mid-diaphysis. Humans show to have no significant difference between quadrants of this area’s MTS, congruent with what is expected in a torsional load-bearing area of bone.

An Investigation Of The Phylogenetic Affinities Of Sivaladapidae Within Adapoidea, Kathleen Rust

Theses and Dissertations

This study presents a phylogenetic analysis incorporating 82 dental characters to clarify the evolutionary relationships of Sivaladapidae within the broader context of Adapoidea. Results suggest that sivaladapids share a close evolutionary relationship with European adapoids.

Worldwide Distribution Of The Human Apolipoprotein E Gene - The Association Between Apoe, Subsistence, And Latitude, Tiffany S. Ho

Theses and Dissertations

The human apolipoprotein E gene (APOE) plays an important role in metabolizing lipids, regulating plasma cholesterol, and maintaining biological function. Structural differences in APOE variants impact cholesterol absorption and health risk, so that alleles serve as biomarkers for numerous cardiovascular and neurological diseases (Lai 2015). Variant differences are determined by changes in two single nucleotide polymorphisms (SNPs), rs429358 and rs7412. Distribution of alleles varies across populations. Allele frequencies in populations have been shown to be associated with cultural and environmental factors, including subsistence strategy and latitude (Eisenberg 2010).

This study aims to provide a cross-population, genetic association study …
