Intrapopulation variation in habitat use is commonly seen among mobile animals, yet the
mechanisms maintaining it have rarely been researched among untrackable species. To …

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

The circulation in the Western Equatorial Atlantic is characterized by a highly dynamic
mesoscale activity that shapes the Guiana continental shelf. Olive ridley sea turtles …

Collecting tissue samples from sea turtles for stable isotope analysis often occurs at remote
field sites. For blood tissue, samples are treated with an anticoagulant that allows for later …

Marine mammals and turtles are often studied using the carcasses of stranded dead
individuals. Since decomposition processes might modify the stable isotope ratios of tissues …

Intra-specific variation in life history traits and/or population trends provides 'natural
experiments' to identify causes of observable differences among populations of organisms …

A central issue in life history theory is how organisms trade off current and future
reproduction. A variety of organisms exhibit intermittent breeding, meaning sexually mature …

Here, we evaluate maternal offloading of 16 trace elements (Essential: Co, Cr, Cu, Fe, Mn,
Ni, Se and Zn; Nonessential: Al, As, Ba, Cd, Hg, Pb, Tl and U) and determine mother …

Feeding ecology and geographic location are 2 major factors influencing animal stable
isotope signatures, but their relative contributions are poorly understood, which limits the …

Highly migratory marine species pose a challenge for the identification of management units
due to the absence of clear oceanographic barriers. The population structure of North …
