Sink or swim: strategies for cost-efficient diving by marine mammals.
Locomotor activity by diving marine mammals is accomplished while breath-holding and often exceeds predicted aerobic capacities. Video sequences of freely diving seals and whales wearing submersibleExpand

From wind to whales: trophic links in a coastal upwelling system
Blue whales Balaenoptera musculus meet the highest prey demands of any predator that has ever existed by feeding exclusively upon dense but patchy schools of pelagic euphausiids. We examined the roleExpand

Severity of the effects of invasive rats on seabirds: a global review.
Invasive rats are some of the largest contributors to seabird extinction and endangerment worldwide. We conducted a meta-analysis of studies on seabird-rat interactions to examine which seabirdExpand

Foraging Behavior and Physiological Adaptation for Diving in Thick‐Billed Murres
Foraging behavior and physiological adaptations for diving were studied in Thick-billed Murres, Uria lomvia, in the field and laboratory. Electronic, light-emitting diode, and capillary recordingExpand

Mechanical versus physiological determinants of swimming speeds in diving Brünnich's guillemots.
For fast flapping flight of birds in air, the maximum power and efficiency of the muscles occur over a limited range of contraction speeds and loads. Thus, contraction frequency and work per strokeExpand

Diving metabolism and thermoregulation in common and thick-billed murres
The diving and thermoregulatory metabolic rates of two species of diving seabrid, common (Uria aalge) and thick-billed murres (U. lomvia), were studied in the laboratory. Post-absorptive restingExpand

Introduced Predators Transform Subarctic Islands from Grassland to Tundra
Top predators often have powerful direct effects on prey populations, but whether these direct effects propagate to the base of terrestrial food webs is debated. There are few examples of trophicExpand

The diving behavior of blue and fin whales: is dive duration shorter than expected based on oxygen stores?
Many diving seabirds and marine mammals have been found to regularly exceed their theoretical aerobic dive limit (TADL). No animals have been found to dive for durations that are consistently shorterExpand

Blue whale habitat and prey in the California Channel Islands
Abstract Whale Habitat and Prey Studies were conducted off southern California during August 1995 (WHAPS95) and July 1996 (WHAPS96) to (1) study the distribution and activities of blue whales andExpand

Foraging behavior of humpback whales: kinematic and respiratory patterns suggest a high cost for a lunge
SUMMARY Lunge feeding in rorqual whales is a drag-based feeding mechanism that is thought to entail a high energetic cost and consequently limit the maximum dive time of these extraordinarily largeExpand
