Dietary and isotopic specialization: The isotopic niche of three cinclodes ovenbirds
(2009)
By comparing the isotopic composition of tissues deposited at different times, we can identify individuals that shift diets over time and individuals with constant diets. We define an individual as an isotopic specialist ...
Food web structure in a double-basin ultra-oligotrophic lake in Northwest Patagonia, Argentina, using carbon and nitrogen stable isotopes
(Elsevier, 2013-01)
Fish, benthic macroinvertebrates, macrophytes, biofilm, plankton, and terrestrial material were analyzed for stable nitrogen (15N) and carbon isotopes (13C) to study the food web structure of a double-basined, ultra-oligotrophic ...
The stable isotope of nitrogen in an experimental culture of Ulva spp. and its assimilation in the nutrition of white shrimp Litopenaeus vannamei, Baja California Sur, Mexico
(Journal of Applied Phycology, 2012)
Stable nitrogen isotope ratios have been used to study the incorporation of nitrogen into the food webs of marine systems. Some species of algae can be cocultured with shrimp, resulting in a sustainable alternative to ...
Stable carbon (delta(13)C) and nitrogen (delta(15)N) isotopes as natural indicators of live and dry food in Piaractus mesopotamicus (Holmberg, 1887) larval tissue
(Wiley-Blackwell, 2008-03-07)
This study proposed the use of the stable isotope technique to track the type of food utilized by pacu Piaractus mesopotamicus larvae during their development, and to identify the moment when the larvae start using nutrients ...
