Amino acid δ15N underestimation of cetacean trophic positions highlights limited understanding of isotopic fractionation in higher marine consumers

Autor: Cory J. D. Matthews, Rocio I. Ruiz‐Cooley, Corinne Pomerleau, Steven H. Ferguson

Publikováno v: Ecology and Evolution, Vol 10, Iss 7, Pp 3450-3462 (2020)

Abstract Compound‐specific stable isotope analysis (CSIA) of amino acids (AAs) has been rapidly incorporated in ecological studies to resolve consumer trophic position (TP). Differential 15N fractionation of “trophic” AAs, which undergo trophic

Cooperative feeding in common dolphins as suggested by ontogenetic patterns in δ 15 N bulk and amino acids

Autor: Tim Gerrodette, Kerri Danil, Rocio I. Ruiz-Cooley, Susan J. Chivers

Publikováno v: Journal of Animal Ecology. 90:1583-1595

Understanding the effect of stage-specific traits on species feeding habits can reveal how natural selection shapes life strategies. Amino acid (AA) nitrogen stable isotopes (δ15 N) provide multiple proxies of habitat baseline values and diet that c

A meta‐analysis of amino acid δ 15 N trophic enrichment factors in fishes relative to nutritional and ecological drivers

Autor: Sharon Z. Herzka, M. Teresa Nuche-Pascual, Rocio I. Ruiz-Cooley

Publikováno v: Ecosphere, Vol 12, Iss 6, Pp n/a-n/a (2021)

The use of amino acid (AA) nitrogen stable isotopes (δ15N) from consumer tissues aims to provide precise estimates of trophic position (TP), but the drivers of AA isotope fractionation remain unclear. In particular, the main factors driving the vari

Stable isotope analysis reveals differences in domoic acid accumulation and feeding strategies of key vectors in a California hotspot for outbreaks

Autor: John C. Field, Sophie Bernstein, C. Anderson, Rocio I. Ruiz-Cooley, Raphael M. Kudela, Robin C. Dunkin

Publikováno v: Harmful algae. 110

Given the effects of harmful algal blooms (HABs) on human and wildlife health, understanding how domoic acid (DA) is accumulated and transferred through food webs is critical for recognizing the most affected marine communities and predicting ecosyst

Carbon and nitrogen isotopes from top predator amino acids reveal rapidly shifting ocean biochemistry in the outer California Current.

Autor: Rocio I Ruiz-Cooley, Paul L Koch, Paul C Fiedler, Matthew D McCarthy

Publikováno v: PLoS ONE, Vol 9, Iss 10, p e110355 (2014)

Climatic variation alters biochemical and ecological processes, but it is difficult both to quantify the magnitude of such changes, and to differentiate long-term shifts from inter-annual variability. Here, we simultaneously quantify decade-scale iso

Range expansion of the jumbo squid in the NE Pacific: δ15N decrypts multiple origins, migration and habitat use.

Autor: Rocio I Ruiz-Cooley, Lisa T Ballance, Matthew D McCarthy

Publikováno v: PLoS ONE, Vol 8, Iss 3, p e59651 (2013)

Coincident with climate shifts and anthropogenic perturbations, the highly voracious jumbo squid Dosidicus gigas reached unprecedented northern latitudes along the NE Pacific margin post 1997-98. The physical or biological drivers of this expansion,
