Characterizing the Distribution and Behavior of Sperm Whales, Physeter macrocephalus, Over the Otago Submarine Canyons, New Zealand

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Sperm whales (Physeter macrocephalus) play an important role in marine ecosystems as top predators, nutrient vectors, and indicators of ecosystem health. In Aotearoa New Zealand, sperm whales remain largely understudied other than at Kaikōura, a foraging area for males.

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

Mammal 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.

Seeing Through the “Clouds” With Molecular “Eyes”. First eDNA‐Based Detections of Pygmy Sperm Whale (Kogia breviceps) in the Mediterranean Sea

Mammal Review, Volume 56, Issue 1, March 2026.
For the first time, environmental DNA (eDNA) from the Mediterranean Sea reveals the cryptic presence of the pygmy sperm whale (Kogia breviceps). Analysis of 393 samples detected repeated, spatiotemporally structured molecular signals, suggesting a resident population.

Modelling the effect of varying metabolic rate and cardiac output on estimated tissue and blood O2 and CO2 levels in an extreme deep‐diver, the goose‐beaked whale (Ziphius cavirostris)

Experimental Physiology, Volume 111, Issue 3, Page 765-785, 1 March 2026.
Abstract High‐resolution movement data from Cuvier's beaked, or goose‐beaked whale (Ziphius cavirostris, hereafter Ziphius, n = 8) tag deployments (4.1–19.2 days) were used to estimate blood and tissue O2 and CO2 levels. Acceleration and magnetometry data were used to estimate the locomotion cost (LC) from the relationship between activity and the O2 ...
