A note on East Australia Group V Stock humpback whale movement between feeding and breeding areas based on photo-identification
نویسندگان
چکیده
Documentation of humpback whale migratory movements between Australasia and the Southern Ocean has been limited almost exclusively to historical whaling data. This study examines photographic evidence documenting three individual whales their breeding grounds on northeast coast Australia feeding in Area V Ocean. Although these individuals exhibited marked site fidelity same low latitude grounds, sightings high vary by 35° longitude, confirming dispersal Eastern Group Stock Antarctic ground.

A quarter of a world away: female humpback whale moves 10,000 km between breeding areas.
Fidelity of individual animals to breeding sites is a primary determinant of population structure. The degree and scale of philopatry in a population reflect the fitness effects of social facilitation, ecological adaptation and optimal inbreeding. Patterns of breeding-site movement and fidelity are functions of social structure and are frequently sex biased. We report on a female humpback whale...
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 کاملA Note on Suckling Behavior and Laterality in Nursing Humpback Whale Calves from Underwater Observations
We investigated nursing behavior on the Hawaiian breeding grounds for first year humpback whale (Megaptera novaeangliae) calves. We observed and video-documented underwater events with nursing behavior from five different whale groups. The observed nursing events include behaviors where a calf positions itself at a 30-45° angle to the midline of the mother's body, with its mouth touching her ma...
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 کاملHumpback Whale Song and Foraging Behavior on an Antarctic Feeding Ground
Reports of humpback whale (Megaptera novaeangliae) song chorusing occurring outside the breeding grounds are becoming more common, but song structure and underwater behavior of individual singers on feeding grounds and migration routes remain unknown. Here, ten humpback whales in the Western Antarctic Peninsula were tagged in May 2010 with non-invasive, suction-cup attached tags to study foragi...
