Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
2014/4/2
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...
Trophic relationships of exotic anadromous salmonids in the southern Patagonian Shelf as inferred from stable isotopes
Trophic relationships exotic anadromous salmonids the southern Patagonian Shelf inferred stable isotopes
2014/4/21
On the basis of their thermal preferences, salmon introduced in South America can distribute over the whole Southern Patagonian Shelf Ecosystem (SPSE). Stable isotope (d13C andd15N) data show that the...
Protozoans as a food source for Antarctic krill, Euphausia superba: Complementary insights from stomach content, fatty acids, and stable isotopes

We studied the diet of Antarctic krill, Euphausia superba, at five stations across the southwest Atlantic sector in summer 2003 by analyzing stomach content, fatty acids, and stable isotopes on the sa...
Interpreting stable isotopes in food webs: Recognizing the role of time averaging at different trophic levels
stable isotopes food webs averaging at different trophic levels
2014/5/26
Lake Tanganyika, East Africa, has a simple pelagic food chain, and trophic relationships have been established previously from gut-content analysis. Instead of expected isotopic enrichment from phytop...
Interpreting stable isotopes from macroinvertebrate foodwebs in saline wetlands
Interpreting stable isotopes macroinvertebrate foodwebs saline wetlands
2014/5/26
We compared stable-isotope (δ13C and δ15N) and gut-content analyses of macroinvertebrate foodwebs in saline wetlands of the Laramie Basin, Wyoming, USA. Standard assumptions of stable-isotope fraction...
