Animal‐attached remote sensing, or bio‐logging, refers to the deployment of autonomous
recording tags on free‐living animals, so that multiple variables can be monitored at rates of …

Misleading interpretations of “gastroliths” in fossil taxa have complicated the use of this term
in palaeontology. This pa− per reviews the definitions and ascribed functions of gastroliths …

Sexual segregation in foraging is predicted from the great size disparity of male and female
northern elephant seals, Mirounga angustirostris. Our aim was to test this prediction by …

Locomotor activity by diving marine mammals is accomplished while breath-holding and
often exceeds predicted aerobic capacities. Video sequences of freely diving seals and …

The mesopelagic zone of the northeast Pacific Ocean is an important foraging habitat for
many predators, yet few studies have addressed the factors driving basin-scale predator …

Drag and buoyancy are two primary external forces acting on diving marine mammals. The
strength of these forces modulates the energetic cost of movement and may influence …

Measurements of body size and mass are fundamental to pinniped population management
and research. Manual measurements tend to be accurate but are invasive and logistically …

Leatherback sea turtles, Dermochelys coriacea, undertake broad oceanic movements. While
satellite telemetry has been used to investigate the post-nesting behaviour of female turtles …

Reliable estimates of field metabolic rates (FMRs) in wild animals are essential for
quantifying their ecological roles, as well as for evaluating fitness consequences of …

Using suction–cup attached time–depth recorder/VHF radio tags, we have obtained the first
diving data on northern bottlenose whales (Hyperoodon ampullatus), the first such data on …
