Estimating Demographic Parameters for Bearded Seals, <i>Erignathus barbatus</i>, in Alaska Using Close‐Kin Mark‐Recapture Methods Open
Reliable estimates of population abundance and demographics are essential for managing harvested species. Ice‐associated phocids, “ice seals,” are a vital resource for subsistence‐dependent coastal Native communities in western and norther…

Update on the status of gray whales since the 2020 Implementation Review Open
The International Whaling Commission’s Scientific Committee conducts regular Implementation Reviews (IRs) of the biology, threats and status of whale species subject to aboriginal subsistence whaling. The last IR of plans for hunting easte…

Global conservation genomics of blue whales calls into question subspecies taxonomy and refines knowledge of population structure Open
Blue whales ( Balaenoptera musculus ) are the largest living animal and, like other baleen whales, became endangered due to whaling. Here, we used population genomics to infer the number, distribution and other characteristics of subspecie…

A High-Quality Blue Whale Genome, Segmental Duplications, and Historical Demography Open
The blue whale, Balaenoptera musculus, is the largest animal known to have ever existed, making it an important case study in longevity and resistance to cancer. To further this and other blue whale-related research, we report a reference-…

Guidelines and quantitative standards for improved cetacean taxonomy using full mitochondrial genomes Open
In many organisms, especially those of conservation concern, traditional lines of evidence for taxonomic delineation, such as morphological data, are often difficult to obtain. In these cases, genetic data are often the only source of info…

The migratory whale herd concept: A novel unit to conserve under the ecological paradigm Open
Photographic and genetic studies have revealed the complex population structure of migratory large whales. Most research and management are geographically based, focusing on either wintering or summering areas, which in most cases fails to…

Northern Range Expansion of California Coastal Bottlenose Dolphins (Tursiops truncatus) Open
The California coastal stock of bottlenose dolphins (Tursiops truncatus) expanded its range north from the Southern California Bight, its historical range, into Central California coincident with the 1982-1983 El Niño event. Since the late…

Gray Whale Sex, Reproductive Behavior, and Social Strategies Open
Gray whale sexual behavior and copulation are observed throughout their range. The most prominent period for reproductive behavior is during the southward migration from summer feeding areas to wintering areas where some breeding occurs an…

Influence of Life-History Parameters on Persistent Organic Pollutant Concentrations in Blubber of Eastern North Pacific Gray Whales (<i>Eschrichtius robustus</i>) Open
Exposure to persistent organic pollutants (POPs) can significantly impact marine mammal health, reproduction, and fitness. This study addresses a significant 20-year gap in gray whale contaminant monitoring through analysis of POPs in 120 …

A high-quality blue whale genome, segmental duplications, and historical demography Open
BackgroundThe blue whale, Balaenoptera musculus , is the largest animal known to have ever existed. Body size is tightly coupled to cell metabolism and environmental adaptations. A high-quality genome assembly of this magnificent animal wi…

Naturally stressed? Glucocorticoid profiles in blubber of blue and gray whales in response to life history parameters Open
The goal of the present study was to carry out a thorough methodological validation and describe baseline profiles for glucocorticoid hormones (cortisol and corticosterone) in blubber from blue ( n = 77) and gray ( n = 103) whales from the…
View article: Application of endocrine biomarkers to update information on reproductive physiology in gray whale (Eschrichtius robustus)
Application of endocrine biomarkers to update information on reproductive physiology in gray whale (Eschrichtius robustus) Open
Most of our knowledge on reproductive biology of gray whales dates back to scientific research conducted during commercial whaling in the late 1950s and 1960s. The goal of the present study was to provide updated insights on reproductive p…

Guidelines and quantitative standards to improve consistency in cetacean subspecies and species delimitation relying on molecular genetic data Open
Taxonomy is an imprecise science that delimits the evolutionary continuum into discrete categories. For marine mammals, this science is complicated by the relative lack of morphological data for taxa that inhabit remote and often vast rang…

A review of molecular genetic markers and analytical approaches that have been used for delimiting marine mammal subspecies and species Open
Uncertainty in marine mammal taxonomy is increasingly being addressed using molecular genetic data. We examined 32 peer‐reviewed articles published between 1994 and 2011to review methodological practices, consistency of markers and analyti…

Redrawing the map: mt<span>DNA</span> provides new insight into the distribution and diversity of short‐finned pilot whales in the Pacific Ocean Open
Correlations between morphological and genetic data provide evidence to delineate species or evolutionarily significant units, which then become the units to conserve in management plans. Here, we examine the distribution and genetic diffe…
