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 ...
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 isotopes of carbon and nitrogen in the study of organochlorine contaminants in albatrosses and petrels
(2014-04-22)
Carbon and nitrogen stable isotopes in albatrosses and petrels collected off southern Brazil were compared with concentrations of organochlorine contaminants (OCs). d13C and d15N values, as well as OCs concentrations, ...
Factors controlling the stable isotope composition and C:N ratio of seston and periphyton in shallow lake mesocosms with contrasting nutrient loadings and temperatures
(Wiley Blackwell Publishing, Inc, 2017-09)
Carbon (C) and nitrogen (N) stable isotope composition (15N:14N, δ15N and 13C:12C, δ13C) have been widely used to elucidate changes in aquatic ecosystem dynamics created by eutrophication and climate warming, often, however, ...
Stable isotopes on jumbo squid (Dosidicus gigas) beaks to esitmate its trophic positon: comparison between stomach contents and stable isotopes
(Journal of the Marine Biological Association of the United Kingdom, 2006)
Stomach contents and carbon (C) and nitrogen (N) stable isotope analysis were used to evaluate trophic relationships of jumbo squid, Dosidicus gigas. Buccal masses, beaks and stomach contents of large and medium maturing-sized ...
Food provisioning in magellanic penguins as inferred from stable isotope ratios
(John Wiley & Sons Ltd, 2018-03)
Rationale: Food provisioning is considered one of the main traits affecting offspring fitness. Differences in food provisioning between sexes, particularly in dimorphic species, could affect the amount and type of food ...
