A bstract Despite the extensive use of photographic identification methods to investigate humpback whales in North Pacific, few quantitative analyses have been conducted. We report on a comprehensive analysis interchange Pacific among three wintering regions (Mexico, Hawaii, and Japan) each with two subareas, feeding areas that extended from southern California Aleutian Islands. Of 6,413 photographs obtained by 16 independent research groups between 1990 1993 examined for this study, 3,650...
ABSTRACT We summarize fin whale Balaenoptera physalus catch statistics, sighting data, mark recoveries and acoustics data. The annual cycle of most populations whales had been thought to entail regular migrations between high‐latitude summer feeding grounds lower‐latitude winter grounds. Here we present evidence more complex varied movement patterns. During summer, range from the Chukchi Sea south 35 °N on Sanriku coast Honshu, Subarctic Boundary (ca. 42 °N) in western central Pacific, 32...
We used photo-identification records to estimate annual survival of adult humpback whales (Megaptera novaeangliae) for the central North Pacific stock using models within software application Program MARK. The analysis is based on 10,567 photographs 2,400 individual taken from 1979 1996. winters in Hawai'i and migrates discrete feeding areas Alaska summer autumn. Cormack–Jolly–Seber (CJS) sightings was 0.963 (95% confidence interval [CI]: 0.944–0.978) Pradel CI0.944–0.976), with a population...
Abstract Springer et al . (2003) contend that sequential declines occurred in North Pacific populations of harbor and fur seals, Steller sea lions, otters. They hypothesize these were due to increased predation by killer whales, when industrial whaling's removal large whales as a supposed primary food source precipitated prey switch. Using regional approach, we reexamined whale catch data, observations, the current biomass trends potential prey, found little support for prey‐switching...
Abstract We investigated the distribution and movements of sperm whales ( Physeter macrocephalus ) in North Pacific by analyzing whaling data movement marked with Discovery marks. Prior studies suggested that there were discrete “stocks” whales, assuming intervals between historical areas concentration indicated subpopulation boundaries. Our analyses clearly refute this assumption: marking suggest no obvious divisions separate demes or stocks within Pacific. Sperm appear to be nomadic show...
Abstract Three subspecies of fin whales (Balaenoptera physalus) are currently recognized, including the northern whale (B. p. physalus), southern quoyi), and pygmy patachonica). The Northern Hemisphere encompasses in both North Atlantic Pacific oceans. A recent analysis 154 mitogenome sequences from these two ocean basins Southern suggested that populations should be treated as different subspecies. Using sequences, this study, we conduct analyses on a larger mtDNA control region data set,...

Sighting histories of individually identified female humpback whales (Megaptera novaeangliae) in their winter and summer ranges were used to investigate mortality North Pacific whale calves. We compiled records collected between 1979 1995 by eight independent research groups, which yielded 29 cases where 25 different mothers sighted Hawai'i later the same year Alaska. In 7 cases, a calf with its mother was missing from mother's Alaska sighting(s). After investigating many factors, we...
The migratory destinations of humpback whales that winter off the Pacific coast Mexico were examined using photo-identification. Fluke photographs taken between 1983 and 1993 from three main whale aggregations in this area (383 Mainland coast; 471 Baja California Peninsula; 450 Revillagigedo Archipelago) compared with collections all known summering grounds North (593 California-Oregon-Washington; 48 British Columbia; 429 Southeastern Alaska; 141 Prince William Sound; 133 western Gulf Alaska...
The advent of massive parallel sequencing technologies has resulted in an increase studies based upon complete mitochondrial genome DNA sequences that revisit the taxonomic status within and among species. Spatially distinct monophyly such mitogenomic genealogies, i.e., sharing a recent common ancestor con-specific samples collected same region been viewed as evidence for subspecies. Several cetaceans have employed this criterion to suggest subsequent intraspecific revisions. We reason...
Abstract Invasive tags designed to provide information on animal movements through radio or satellite monitoring have tremendous potential for the study of whales and other cetaceans. However, date there been no published studies survival tagged animals over periods years decades. Researchers from National Marine Mammal Laboratory Woods Hole Oceanographic Institution tracked five humpback with implanted in southeastern Alaska August 1976 July 1977, two Prince William Sound, Alaska, June...
The Gulf of California, Mexico is home to many cetacean species, including a presumed resident population fin whales, Balaenoptera physalus. Past studies reported very low levels genetic diversity among California whales and significant level differentiation from con-specifics in the eastern North Pacific. aim present study was assess degree timing isolation analysis 18 nuclear microsatellite genotypes 402 samples 565 mitochondrial control region DNA sequences (including retrieved NCBI)....
