HUMPBACK 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 کاملHUMPBACK WHALE ( Megaptera novaeangliae ) : Eastern North Pacific Stock
STOCK DEFINITION AND GEOGRAPHIC RANGE Although the International Whaling Commission (IWC) only considered one stock (Donovan 1991), there is now good evidence for multiple populations of humpback whales in the North Pacific (Johnson and Wolman 1984; Baker et al. 1990). Aerial, vessel, and photo-identification surveys, and genetic analyses indicate that within the U.S. EEZ, there are at least th...
متن کاملMicrosatellite genetic distances between oceanic populations of the humpback whale (Megaptera novaeangliae).
Mitochondrial DNA haplotypes of humpback whales show strong segregation between oceanic populations and between feeding grounds within oceans, but this highly structured pattern does not exclude the possibility of extensive nuclear gene flow. Here we present allele frequency data for four microsatellite loci typed across samples from four major oceanic regions: the North Atlantic (two mitochond...
متن کاملThe Nature of Humpback Whale (Megaptera novaeangliae) Song
The nature of humpback whale (Megaptera novaeangliae) song has long interested both scientists and the general public. Research strongly indicates that humpback whale song is an important component in the social behaviour of breeding humpback whales, with proposals that the song has an intraand/or inter-sexual selection component. Some scientists, however, have alternate hypotheses, such as son...
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...
