Interpreting Predator – Prey Interactions in Cayuga Lake Fishes Using Fatty Acid Signature Analysis
Fatty acids are transferred from prey to predator and can be used to assess trophic interactions in aquatic food webs. Therefore, to better understand Cayuga Lake food web dynamics, fatty acid signatures (FAS) of lake trout (Salvelinus namaycush) were compared to two major prey species in the lake; …

A multi-indicator approach to dietary assessments within Lake Michigan's nearshore area
… to infer community structure for decades, while fatty acid signatures have only recently been used in terrestrial and marine systems to explore dietary trends. Using a data set collected from Lake Michigan throughout the 2010 intensive sampling year, I: 1) examined foraging patterns of juvenile …

Polar Bear (Ursus Maritimus) Foraging Ecology in the Western Canadian Arctic
… and temporally. This thesis used quantitative fatty acid signature analysis (QFASA) to estimate the diets, and adipose tissue lipid content to estimate the body condition, of polar bears in three western Canadian Arctic subpopulations: Northern Beaufort Sea, Southern Beaufort Sea, and Viscount …

Tracing the effects of diets in freshwater fish using fatty acid profiles
… is to contribute to our knowledge of how fatty acids can be used as diet indicators in freshwater systems. More precisely this work was an effort to explore a tool that can be used to describe what salmonids have consumed during the foraging period of the year and relate that to the …
