Stable isotope analysis has become a standard ecological tool for elucidating feeding
relationships of organisms and determining food web structure and connectivity. There …

A feeding trial was performed in the laboratory with the catfish species Pterygoplichthys
disjunctivus to determine stable carbon (13 C) and nitrogen (15 N) turnover rates and …

Multi-species assemblages can help identify key resources in their habitat by evaluating
how they are partitioning their resources. Here we used the isotopic niche of loggerhead …

Trophic position and niche width are fundamental components of a species' ecology,
reflecting resource use, and influencing key demographic parameters such as somatic …

Stable isotope analysis can be used to infer geospatial linkages of highly migratory species.
Identifying foraging grounds of marine organisms from their isotopic signatures is becoming …

Differential foraging area use can affect population demographics of highly migratory fauna
because of differential environmental changes and anthropogenic threats among those …

Abstract Knowledge regarding the trophic ecology, including the feeding habits of olive
ridley sea turtles (Lepidochelys olivacea), is scarce. Although few investigations have been …

White sharks Carcharodon carcharias and shortfin mako sharks Isurus oxyrinchus are
globally distributed apex predators and keystone species. However, regional information …

Diet–tissue discrimination factors (Δ13C and Δ15N) are influenced by variables including
the tissues being analysed and the taxon of the consumer and its prey. Whilst differences in …

Most studies on the foraging ecology of loggerhead turtles (Caretta caretta) have focused on
adult females and juveniles. Little is known about the foraging patterns of adult male …
