Influence of Diet On the Distribtion of Nitrogen Isotopes in Animals
Michael J. DeNiro,Samuel Epstein +1 more
TL;DR: In this article, the influence of diet on the distribution of nitrogen isotopes in animals was investigated by analyzing animals grown in the laboratory on diets of constant nitrogen isotopic composition and found that the variability of the relationship between the δ^(15)N values of animals and their diets is greater for different individuals raised on the same diet than for the same species raised on different diets.

Godley +43 more
TL;DR: A systematic review of the peer-reviewed literature (2014 and 2015) attributing papers to the original 20 meta-questions was conducted by as discussed by the authors, who found that significant research is being expended towards global priorities for management and conservation of sea turtles, including reproductive biology, biogeography, population ecology, threats and conservation strategies.

Enhancing the TurtleWatch product for leatherback sea turtles, a dynamic habitat model for ecosystem-based management
Evan A. Howell,Aimee L. Hoover,Aimee L. Hoover,Scott R. Benson,Helen Bailey,Jeffrey J. Polovina,Jeffrey A. Seminoff,Peter H. Dutton +7 more
TL;DR: The updated TurtleWatch product provides a tool for dynamic management of the Hawaii-based shallow-set fishery to aid in the bycatch reduction of both species as mentioned in this paper, which can be used by managers and industry to make dynamic management decisions to potentially reduce incidentally capturing turtles during fishing operations.

Tropicalization of temperate ecosystems in North America: The northward range expansion of tropical organisms in response to warming winter temperatures.

TL;DR: This paper examined the influence of extreme cold events on the northward range limits of a diverse group of tropical organisms, including terrestrial plants, coastal wetland plants and coastal fishes, sea turtles, terrestrial reptiles, amphibians, manatees, and insects.

Finding the way to the top: how the composition of oceanic mid-trophic micronekton groups determines apex predator biomass in the central North Pacific
TL;DR: In this article, a model of the pelagic ecosystem for the area of the central North Pacific occupied by the Hawaii-based longline fishery was updated and expanded to examine how changes in various micronekton groups impact apex predator biomass.

Using stable isotopes to estimate trophic position: models, methods, and assumptions
TL;DR: In this article, the authors developed and discussed methods for generating an isotopic baseline and evaluate the assump- tions required to estimate the trophic position of consumers using stable isotopes in multiple ecosystem studies.

Stable isotopes in ecosystem studies
Bruce J. Peterson,Brian Fry +1 more
TL;DR: The use of stable isotopes to solve biogeochemical problems in ecosystem analysis is increasing rapidly because stable isotope data can contribute both source-sink (tracer) and process information: the elements C, N, S, H, and all have more than one isotope, and isotopic compositions of natural materials can be measured with great precision with a mass spectrometer as mentioned in this paper.

Stepwise enrichment of 15N along food chains: Further evidence and the relation between δ15N and animal age
Masao Minagawa,Eitaro Wada +1 more
TL;DR: The isotopic composition of nitrogen was measured in marine and fresh-water animals from the East China Sea, The Bering Sea, Lake Ashinoko and Usujiri intertidal zone as mentioned in this paper.

Variation in trophic shift for stable isotope ratios of carbon, nitrogen, and sulfur
TL;DR: For example, this article found that the trophic shift for C was lower for consumers acidified prior to analysis than for unacidified samples ( +0.5 + 0.13%o rather than 0.0%o, as commonly assumed).
