Gray Whale Energy Requirements
Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT Eastern North Pacific gray whales (Eschrichtius robustus) rely on energy obtained from Arctic feeding grounds to complete their 15,000–20,000 km annual round‐trip migration between feeding and breeding areas. However, quantitative estimates of their food requirements remain scarce. Using an age‐structured bioenergetics model incorporating life

Evidence from Strandings for Geomagnetic Sensitivity in Cetaceans [PDF]
, 1986 We tested the hypothesis that cetaceans use weak anomalies in the geomagnetic field as cues for orientation, navigation and/or piloting. Using the positions of 212 stranding events of live animals in the Smith sonian compilation which fall within the ...

Marine Mammal Science, 2018 AbstractBeaked whales are vulnerable to the impacts of disturbance from several sources of anthropogenic sound. Here we report the distribution and abundance of beaked whales off Cape Hatteras, North Carolina, U.S.A., an area utilized by the U.S. Navy for training exercises, and of particular interest for seismic geophysical surveys.

Environmental and Evolutionary Forces Shaping Penguin Geographic Limits
Journal of Biogeography, Volume 52, Issue 9, September 2025.ABSTRACT Aim Penguins are seabirds exclusively found in the Southern Hemisphere, with their existence dating back to the late Cretaceous. Despite their exceptional dispersal capabilities, which allow them to inhabit a wide range of environments—from polar regions to temperate zones, and even near the Equator—penguins are absent in the Northern ...

Phylogenetic review of tonal sound production in whales in relation to sociality [PDF]
, 2007 Background It is widely held that in toothed whales, high frequency tonal sounds called \u27whistles\u27 evolved in association with \u27sociality\u27 because in delphinids they are used in a social context.
