Geographical and Seasonal Distribution of Australian Pygmy Right Whales (Caperea marginata) Based on Passive Acoustics

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT The pygmy right whale (Caperea marginata) is one of the least studied mysticete species. To shed light on its geographic and seasonal distribution, we compiled archival acoustic recordings from 26 sites across southern Australia and developed a deep‐learning detector for pygmy right whale “doublet” vocalizations.

Records of beaked whales (family Ziphiidae) in Western Australian waters

open access: yesMarine Biodiversity Records, 2014
Western Australia has an extensive coastline extending 12889 km (excluding islands) from latitude 35 degrees in the south to 14 degrees in the north. The extensive coastline intersects the distribution of many species of beaked whale. A total of 74 Ziphiidae were recorded as stranded along the Western Australian coast between 1940 and 2010 (70 years ...

Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.

Environmental DNA survey of the Winter Salmonosphere in the Gulf of Alaska

open access: yesEnvironmental DNA, 2023
Pacific salmon (Oncorhynchus spp.) are a foundation species around the north Pacific, yet many wild populations have experienced steep declines over the last decades associated with decreased marine survival. Due to limited sampling, our understanding of

Genome sequence of a gammaherpesvirus from a common bottlenose dolphin (Tursiops truncatus) [PDF]

open access: yes, 2017
A herpesvirus genome was sequenced directly from a biopsy specimen of a rectal lesion from a female common bottlenose dolphin. This genome sequence comprises a unique region (161,235 bp) flanked by multiple copies of a terminal repeat (4,431 bp) and ...

Stranding of a Hector's Beaked Whale (Mesoplodon hectori) (Gray 1871) From South Australia Unearths Novel Additional Teeth

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Most extant beaked whales have reduced dentition of one or two pairs of tusk‐like, mandibular teeth that erupt through the gum only in adult males. Additional teeth have been recorded in several species and genera. A juvenile Hector's beaked whale (SAMA M26434) having additional teeth was collected in South Australia and its skeleton and ...

Stranding of four Sowerby's beaked whales (Mesoplodon bidens) in Terceira, Azores [PDF]

open access: yes, 2016
Sowerby's beaked whales are little known members of the beaked whale family (Ziphiidae). Based on data collected from strandings, this species is found in temperate and subarctic waters in the eastern and western North Atlantic.

Description of the skeleton of the fossil beaked whale Messapicetus gregarius: searching potential proxies for deep-diving abilities [PDF]

open access: yesFossil Record, 2018
Ziphiidae (beaked whales) are a successful family of medium- to large-sized toothed whales. Their extant members perform regular deep dives beyond the photic zone to forage for cephalopods and fish.

Marine Mammals in the Anthropocene: Developing a Systematic Evidence Base of Threats to Nineteen Species

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
Marine mammals are vulnerable to a variety of anthropogenic threats, yet a global systematic map of the literature for 19 species found both spatial and temporal disparity in research effort between threats and between species. There are knowledge gaps for species and threats, with effort unequal across many species' ranges.
