15: The Diet Composition of Beaked Whales and Melon-Headed Whales from the North Pacific
نویسندگان
چکیده
Knowledge of the diet of a species is crucial for understanding it’s behavior and ecology, and also has relevance to assessing the impact of potential changes in behavior or spatial use that may be associated with anthropogenic activities. Assessing diet for many species of cetaceans is difficult, given that most foraging occurs far below the surface and that stomach contents of stranded animals are rarely available. Very little information on food habits of most species of beaked whales or of melon-headed whales (Peponocephala electra) is available from any region of the world.

MELON-HEADED WHALE (Peponocephala electra): Hawaiian Islands Stock Complex: Hawaiian Islands & Kohala Resident Stocks
STOCK DEFINITION AND GEOGRAPHIC RANGE Melon-headed whales are found in tropical and warm-temperate waters throughout the world. The distribution of reported sightings suggests that the oceanic habitat of this species is primarily equatorial waters (Perryman et al. 1994). Small numbers have been taken in the tuna purse-seine fishery in the eastern tropical Pacific, and they are occasionally kill...
متن کاملSpatio-Temporal Patterns of Beaked Whale Echolocation Signals in the North Pacific
At least ten species of beaked whales inhabit the North Pacific, but little is known about their abundance, ecology, and behavior, as they are elusive and difficult to distinguish visually at sea. Six of these species produce known species-specific frequency modulated (FM) echolocation pulses: Baird's, Blainville's, Cuvier's, Deraniyagala's, Longman's, and Stejneger's beaked whales. Additionall...

Dive capacity among toothed whales (suborder: Odontoceti) has been shown to generally increase with body mass in a relationship closely linked to the allometric scaling of metabolic rates. However, two odontocete species tagged in this study, the Blainville's beaked whale Mesoplodon densirostris and the Cuvier's beaked whale Ziphius cavirostris, confounded expectations of a simple allometric re...

Within the Gulf of Guinea high levels of fisheries-related cetacean mortality (bycatch and direct-capture) has been documented. For locally rare species such removals could potentially lead to significant population level effects. However, information on the cetacean abundance and distribution is scarce. Similarly, it remains largely unreported where fishing fleets operate offshore. A cetacean ...

DNA sequence data enable not only the inference of evolutionary relationships and population histories but also represent a powerful tool for uncovering hidden biodiversity, an approach that has become known as "DNA taxonomy" (Dalebout eta/. 2002, Meegasku.mhura.eta/. 2002, Hebert eta/. 2004). The application of DNA taxonomy to beaked whales (Ziphiidae), the least known of all cetacean families...
