Phylogenetic Affinities Of Homo Floresiensis Incorporating Postcranial Characters, Kristina M. Feeney
Phylogenetic Affinities Of Homo Floresiensis Incorporating Postcranial Characters, Kristina M. Feeney
Theses and Dissertations
The objective of this analysis is to generate hypotheses regarding the evolution and ancestry of Homo floresiensis. Building on the previous study by Argue et al. (2009) by including a much larger sample of postcranial data for a more integrated picture of primitive and derived features across the skeleton.
Sexual Dimorphism In The Femur And Pelvis Of Cebus Apella With A Randomization Experiment Examining Sample Size In The Fossil Record, Ryan P. Schaars
Sexual Dimorphism In The Femur And Pelvis Of Cebus Apella With A Randomization Experiment Examining Sample Size In The Fossil Record, Ryan P. Schaars
Theses and Dissertations
Measures of sexual dimorphism for six skeletal traits of the femur and pelvis of Cebus apella were calculated for 18 individuals to better understand primate skeletal dimorphism. A randomization experiment was also conducted on the measures of sexual dimorphism to examine sample size in the primate fossil record.
Reduced Immune Investment With Energy Stress: Evidence From A Mouse Model And Human Studies, Alaina L. Schneider
Reduced Immune Investment With Energy Stress: Evidence From A Mouse Model And Human Studies, Alaina L. Schneider
Theses and Dissertations
During periods of energy stress, animals will prioritize and allocate energy from non-essential to essential tasks. Using a mouse model and published human data, we found that during periods of energy stress, energy is allocated away from immune function, and is prioritized for physical activity usage.
Ecological Niche Modeling Of The Genus Papio, Amanda J. Fuchs
Ecological Niche Modeling Of The Genus Papio, Amanda J. Fuchs
Theses and Dissertations
Ecological niche modeling investigates how climatic variables have influenced taxonomic diversity in Papio. Models performed well suggesting climatic variables influence the distribution of baboon species. Niche overlap among all possible pairs of taxa determined that species exhibited significantly different niches. The results of these models support a parapatric speciation scenario.
Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell
Theses and Dissertations
Ruffed lemur (Varecia spp.) color vision research was conducted using a multidisciplinary approach: psychophysics, genetic analysis, technology, and animal training. The behavioral manifestation of Varecia spp. trichromacy was shown using a touchscreen apparatus (SMARTA). Trichromats performed better than dichromats when discriminating red from green (G2 = 78.10, p < 0.001).
