Human activities have serious impacts on marine apex predators. Inadequate knowledge of
the spatial and trophic ecology of these marine animals ultimately compromises the viability …

Stable isotope analysis (SIA) has become a powerful and widely utilised tool in ecological
studies, and more specifically has been used to answer conservation questions regarding …

Understanding seabird marine habitat affinities, at-sea behavior, variability in reproductive
success, migratory patterns, phenology, and other life history traits depends primarily on …

In recent years, the use of intrinsic markers such as stable isotopes to link breeding and
foraging grounds of migratory species has increased. Nevertheless, several assumptions …

When species competing for the same resources coexist, some segregation in the way they
utilize those resources is expected. However, little is known about how closely related …

Maps of the spatial distribution of stable isotope ratios across wide geographic areas
(isoscapes) are increasingly used to study mechanisms of nutrient flux, movements of …

The conservation of threatened seabirds that are highly pelagic, such as the gadfly petrels
Pterodroma spp., depends on understanding the main oceanographic determinants of their …

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 …

Large Marine Ecosystems such as the Canary Current system off West Africa sustains high
abundance of small pelagic prey, which attracts marine predators. Seabirds are top …

Background Natural environments are dynamic systems with conditions varying across
years. Higher trophic level consumers may respond to changes in the distribution and …
