Addressing important questions in animal ecology, physiology, and environmental science
often requires in situ information from wild animals. This difficulty is being overcome by …

It is a golden age for animal movement studies and so an opportune time to assess priorities
for future work. We assembled 40 experts to identify key questions in this field, focussing on …

Animal telemetry is a powerful tool for observing marine animals and the physical
environments that they inhabit, from coastal and continental shelf ecosystems to polar seas …

Detailed observation of the movement of individual animals offers the potential to
understand spatial population processes as the ultimate consequence of individual …

The stable isotope composition of animal tissues can provide intrinsic tags to study the
foraging and migratory ecology of predators in the open ocean. Chapter 13 (this volume) …

Since the discovery of isotopes and the development of precise instrumentation capable of
measuring small differences in isotope abundances, there has been an interest in …

During the last 30 years, at-sea studies of seabirds and marine mammals in the oceans
south of the Subtropical Front have described an association with major frontal areas. More …

Telemetry is a key, widely used tool to understand marine megafauna distribution, habitat
use, behavior, and physiology; however, a critical question remains:“How many animals …

Climate change will alter marine ecosystems; however, the complexity of the food webs,
combined with chronic undersampling, constrains efforts to predict their future and to …

A quantitative assessment of observed and projected environmental changes in the
Southern Ocean (SO) with a potential impact on the marine ecosystem shows:(i) large …
