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 کاملHUMPBACK WHALE ( Megaptera novaeangliae ) : North Atlantic Stock
These six regions represent relatively discrete subpopulations, fidelity to which is determined matrilineally (Clapham and Mayo 1987). Recent genetic analysis of mitochondrial DNA (mtDNA) has indicated that this fidelity has persisted over an evolutionary timescale in at least the Icelandic and Norwegian feeding grounds (Palsbøll et al. 1995, Larsen et al. 1996). Genetic partitioning is not evi...
متن کاملEvidence for the functions of surface-active behaviors in humpback whales (Megaptera novaeangliae)
As part of their social sound repertoire, migrating humpback whales (Megaptera novaeangliae) perform a large variety of surface-active behaviors, such as breaching and repetitive slapping of the pectoral fins and tail flukes; however, little is known about what factors influence these behaviors and what their functions might be. We investigated the potential functions of surface-active behavior...
متن کاملCalling in the Cold: Pervasive Acoustic Presence of Humpback Whales (Megaptera novaeangliae) in Antarctic Coastal Waters
Humpback whales migrate between relatively unproductive tropical or temperate breeding grounds and productive high latitude feeding areas. However, not all individuals of a population undertake the annual migration to the breeding grounds; instead some are thought to remain on the feeding grounds year-round, presumably to avoid the energetic demands of migration. In the Southern Hemisphere, ice...
