Foraging habitat selection and diet quality are key factors that influence individual fitness and meta-population dynamics through effects on demographic rates. There is growing evidence that sea turtles exhibit regional differences in somatic growth

Meta‐analysis of primary producer amino acid δ15N values and their influence on trophic position estimation

Autor: Matthew D. Ramirez, Alexi C. Besser, Seth D. Newsome, Kelton W. McMahon

Publikováno v: Methods in Ecology and Evolution, Vol 12, Iss 10, Pp 1750-1767 (2021)

Abstract Compound‐specific stable isotope analysis of individual amino acids (CSIA‐AA) has emerged as a transformative approach to estimate consumer trophic positions (TPCSIA) that are internally indexed to primary producer nitrogen isotope basel

Embracing variability in amino acid δ15N fractionation: mechanisms, implications, and applications for trophic ecology

Autor: Kelton W. McMahon, Matthew D. McCarthy

Publikováno v: Ecosphere, Vol 7, Iss 12, Pp n/a-n/a (2016)

Abstract Compound‐specific stable isotope analysis (CSIA) of individual amino acids (AAs) has become a powerful analytical tool in trophic ecology. Heavily fractionating “trophic” AAs (e.g., glutamic acid: Glu) provide a robust indicator of tro
