Stable isotope ecology of South African kelp forests
… they occur, they play a key role in coastal ecology and local fisheries. In South Africa, Ecklonia maxima and Laminaria pallida form kelp forests which support diverse ecological communities. The species composition of these communities has been shown to be spatially variable along the South …

Stable isotope ecology of modern herbivores from Mmabolela, Limpopo
This thesis explores the stable isotope ecology of 12 species of co-existing wild herbivores (11 mammals and one reptile) (62 individuals) from Mmabolela, a game farm on the northern border of South Africa in the Limpopo Province. The aim is to investigate and interpret patterns in δ13C, δ15N and …

Behavioural and isotope ecology of marine-foraging chacma baboons (Papio ursinus) on the Cape Peninsula, South Africa
… troop's diet composition modelled from stable isotope ratios of foods, faeces and hair samples. The troop ranged over 45.262km2 and travelled an average of 6.044 km per day over the study period. The troop's activity budget was dominated by walking and feeding behaviour, both of which peaked …

Dietary ecology of Chacma baboons (Papio Ursinus (Kerr, 1972) and Pleistocene Cercopithecoidea in Savanna environments of South Africa
This dissertation deals with the dietary ecology of savanna-dwelling chacma baboons (Papio ursinus), and a number of fossil cercopithecoids, from modern and Pleistocene environments of South Africa, respectively, using principles of stable light isotope ecology. Previous studies of baboon ecology, …

Invasive fish effects on the invertebrate constituents of wetland communities
… of fish and dabbling waterfowl using stable isotope analysis. Brook stickleback (Culaea inconstans) and pumpkinseed (Lipomis gibbosus) pose a potentially growing threat to temperate Pacific drainages of North America due to their ability to outcompete native fauna. Our study compares and …

Carbon flow and food web structure in the mesopelagic zone of the North Atlantic Ocean
… I use carbon compound-specific stable carbon isotope analysis of amino acids (CSIA-AA) and DNA gut metabarcoding methodologies to provide a broad ecological outlook on mesopelagic carbon flow coupled with finer scale taxonomic details. In Chapter 2, I analyze the diets of seven abundant …

Niche Occupancy, Partitioning, and the Role of Trophic Flexibility in Coexistence of Neotropical Bats
… through an ecological lens using stable isotope analysis. I examined individual specialization within populations, population-level responses to seasonal change, and community-level responses to species richness across sites. I found that individuals with preferences for food items or …

A Spatial and Multivariate Approach to Examining Effects of Urbanization on Nitrogen Sources, Organic Matter Inputs, and Trophic Structure in Streams of Cobb and Paulding Counties, Georgia.
… Cardinale and Palmer, 2012). The use of stable isotope analysis for monitoring could be valuable because it accounts for temporal integration from anthropogenic wastewater inputs, characterized by a shift in the abundance of <sup>15</sup>N. This project had three main objectives: (1) to examine …
