The Influence Of Phylogeny And Niche Differentiation On The Diets Of Malagasy Primates, Rebekka S. Hughes
The Influence Of Phylogeny And Niche Differentiation On The Diets Of Malagasy Primates, Rebekka S. Hughes
Theses and Dissertations
Previous studies have shown that haplorhine diet is affected by phylogeny; however, until now studies in Malagasy strepsirrhines were lacking. The evolution of differences in Malagasy primates’ diets appears to differ from the pattern shown in haplorhines. My results indicate that niche differentiation may be a stronger predictor of diet.
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.
African Wild Dog, Lycaon Pictus, Coloration Patterns And Social Aggregation, Ayong J. Kim
African Wild Dog, Lycaon Pictus, Coloration Patterns And Social Aggregation, Ayong J. Kim
Theses and Dissertations
Packs of African wild dogs, Lycaon pictus, were analyzed for coloration patterns and social aggregation tendencies. Mapped locations determined if the coat patterns followed a geographic distribution that corresponded to Southern or Eastern phenotypic forms. Social aggregation tendencies were observed to determine grouping behavior presumably related to individuals’ roles.
Assessing Behavioral Syndromes In Captive Red Pandas (Ailurus Fulgens) Using An Ethological Approach, Tyler C. Bray
Assessing Behavioral Syndromes In Captive Red Pandas (Ailurus Fulgens) Using An Ethological Approach, Tyler C. Bray
Theses and Dissertations
Animal personality has a significant impact on an animal’s physiology and welfare. Eight captive red pandas were observed to determine if personality can be assessed in this species using an ethological approach. Analysis revealed two behavioral dimensions: 1) Active/Exploratory and 2) Maintenance. Age differences were found in the Active/Exploratory dimension.
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).
