TL;DR: A review of the development of cetacean-habitat models, organized according to the primary steps involved in the modeling process, can be found in this paper, where the authors discuss the purposes for which CetACH models are developed, scale issues in marine ecosystems, CETCA and habitat data collection, descriptive and statistical modeling techniques, model selection, and model evaluation.

TL;DR: Though much has been made of the detrimental effects of El Nino events on apex predators, more research is needed to understand the magnitude, and even direction, of these effects on seabirds and cetaceans in space and time.

TL;DR: Differences in published cost-of-flight values support the hypothesis that energetic competition determines flock structure at the low-productivity end of the system, and Sooty Terns have the lowest flight costs and feed in waters of lowest productivity.

TL;DR: The behavior and range patterns of individual bottlenose dolphins during 1984 in the mid-eastern Gulf of California, Mexico were studied in this paper. And the authors found that dolphins used these estuarine areas to feed; 61% of all behavior observed near estuaries was feeding as compared with 23% elsewhere.

TL;DR: Satellite-tracked two different ecotypes of killer whales in McMurdo Sound, Ross Sea, Antarctica, using surface-mounted tags attached with sub-dermal darts, consistent with those of killer whale ecotypes in the eastern North Pacific where mammal-eating ‘transients’ travel widely and are less predictable in their movements.
