Trophic Ecology of Mesopelagic Fish Larvae and Juveniles in the Northern Gulf of Mexico
… in the northern Gulf of Mexico. Bulk-tissue stable isotope analysis of δ<sup>13</sup>C and δ<sup> 15</sup>N were performed on larvae from four different families: Myctophidae (Lanternfishes), Gonostomatidae (Bristlemouths), Sternoptychidae (Hatchetfishes) and Phosichthyidae (Lightfishes). Gut …

Movement and trophic ecology of large pelagic fishes connecting surface waters with the Ocean’s Twilight Zone
… migrations. In this thesis, I begin by using compound-specific stable isotope analysis to trace the flow of carbon through pelagic ecosystems in the northwest Atlantic to three predators: bigeye tuna (Thunnus obesus), swordfish (Xiphias gladius), and yellowfin tuna (Thunnus albacares). I …

Investigating population structure and resource use diversity in Lake Huron Lake (Coregonus clupeaformis) and Round (Prosopium cylindraceum) Whitefish using compound specific stable isotopes analysis
… the use of additional marker types. The stable isotopes of carbon (δ13C) and nitrogen (δ15N) are biochemical markers that reflect differences in prey, habitat, and trophic position within food webs making these isotopes valuable in differentiating ecological populations. Bulk stable …

Organic residue analysis of Red Lustrous Wheelmade Ware vessels traded across the eastern Mediterranean during the Late Bronze Age
… a biomarker for castor oil. Gas-chromatography compound-specific isotope ratio mass spectrometry of selected residues excluded dairy products, ruminant animal fats and fish oils as source materials for the fats/oils, while comparison with a small database of modern oils created during this study …
