The marine habitat use of olive ridley sea turtles (Lepidochelys olivacea) from northeastern
Brazil was analyzed via stable isotope analysis (SIA). Blood (red blood cells and serum) …

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

Determining the diet and trophic status of endangered species can provide insights into their
key habitats and predator-prey relationships, both essential for conservation. Integrating …

Background The leatherback turtle (Dermochelys coriacea) has undergone a dramatic
decline over the last 25 years, and this is believed to be primarily the result of mortality …

In the present study, the herbivory level and the niche breadth of juvenile green turtles
(Chelonia mydas) was investigated through stable isotope metrics in three geographically …

Abstract The southwestern Atlantic Ocean (SWA) represents an important foraging ground
for loggerhead sea turtles (Caretta caretta). Most studies at the region have focused on adult …

Marine turtles are key indicator species of ecosystem function and environmental health,
however, many of their life-history features remain cryptic. Particularly, the understanding of …

Sympatric species may overlap in their use of habitat and dietary resources, which can
increase competition. Comparing the ecological niches and quantifying the degree of niche …

Stable isotope analysis is a useful tool for studying the ecology of marine consumers, as
carbon (δ13C) and nitrogen (δ15N) isotope ratios may reflect individuals' patterns of diet …

An individual's foraging ecology can affect its growth and survival. Stable isotope analysis
has been commonly used to investigate the foraging ecology of marine turtles. However …
