Group-specific effect of interannual water level fluctuation on consumers trophic niche area

open access: yesScientific Reports
The trophic niche area defines the consumer’s ability to utilize a range of food sources and their role in community. However, the trophic niche area might be influenced by a variety of biotic and abiotic factors.

Patterns of δ13C and δ15N in wolverine Gulo gulo tissues from the Brooks Range, Alaska

open access: yesCurrent Zoology, 2009
Knowledge of carnivore diets is essential to understand how carnivore populations respond demographically to variations in prey abundance. Analysis of stable isotopes is a useful complement to traditional methods of analyzing carnivore diets.

Use of the stable isotopes of carbon, nitrogen and sulfur for studies on coastal ecology [PDF]

open access: yes, 2008
Stable isotopes of carbon, nitrogen and sulfur have been successfully used for.diverse applications in coastal ecology. Most studies dealt with the elucidation of food webs using carbon and nitrogen isotopes, and sometimes sulfur isotopes.

Stable isotopes and changing paradigms on soil nitrogen and carbon biogeochemistry

open access: yesEcosistemas, 2010
Muchos de los modelos conceptuales e ideas desarrollados en el ámbito de la biogeoquímica se basan en diagramas de flujo que representan las reservas de nutrientes como "cajas" interconectadas por "flechas" que indican los procesos abióticos y bióticos ...
