Global diversity and oceanic divergence of humpback whales (Megaptera novaeangliae).
Humpback whales (Megaptera novaeangliae) annually undertake the longest migrations between seasonal feeding and breeding grounds of any mammal. Despite this dispersal potential, discontinuous seasonal distributions and migratory patterns suggest that humpbacks form discrete regional populations within each ocean. To better understand the worldwide population history of humpbacks, and the interp...
متن کاملDeaths and Entanglements of Humpback Whales, Megaptera novaeangliae,
Reports of humpback whales, Megaptera novaeangliae, that either died or were entangled in Hawaiian waters from 1972 through October 1996 were analyzed to determine age class (estimated from body length and/or notes), location, annual frequency, and seasonal distribution of occurrence. Using reports collected from the National Marine Fisheries Service Pacific Area Office and published news repor...
متن کاملPassive Acoustic Tracking of Singing Humpback Whales (Megaptera novaeangliae) on a Northwest Atlantic Feeding Ground
Passive acoustic tracking provides an unobtrusive method of studying the movement of sound-producing animals in the marine environment where traditional tracking methods may be costly or infeasible. We used passive acoustic tracking to characterize the fine-scale movements of singing humpback whales (Megaptera novaeangliae) on a northwest Atlantic feeding ground. Male humpback whales produce co...
متن کاملInfluence of environmental parameters on movements and habitat utilization of humpback whales (Megaptera novaeangliae) in the Madagascar breeding ground
Assessing the movement patterns and key habitat features of breeding humpback whales is a prerequisite for the conservation management of this philopatric species. To investigate the interactions between humpback whale movements and environmental conditions off Madagascar, we deployed 25 satellite tags in the northeast and southwest coast of Madagascar. For each recorded position, we collated e...
متن کاملSegregation of migration by feeding ground origin in North Atlantic humpback whales (Megaptera novaeangliae)
Results from a large-scale, capture–recapture study of humpback whales Megaptera novaeangliae in the North Atlantic show that migration timing is influenced by feeding ground origin. No significant differences were observed in the number of individuals from any feeding area that were re-sighted in the common breeding area in the West Indies. However, there was a relationship between the proport...
