The larger the cetacean, the more stationary their sleep? Thermoregulatory constraints on the sleep behaviour of captive cetaceans

Journal of Zoology, Volume 327, Issue 4, Page 376-385, December 2025.
Cetaceans face thermal challenges when sleeping underwater. Our study found that smaller body size correlated with more swim sleep and less stationary sleep, while the opposite was true for larger cetaceans. Additionally, bottlenose dolphins increased swim sleep at lower ambient temperatures, suggesting a sleep strategy influenced by body size and ...

Within‐Ecosystem Comparison of Bigmouth Buffalo Ictiobus cyprinellus and Common Carp Cyprinus carpio Reveals Diverging Population Trajectories, Declining Recruitment, and a Lifespan of 148 Years

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Within‐ecosystem comparison of invasive common carp and native bigmouth buffalo reveals recruitment gaps for bigmouth buffalo longer than any other animal and lifespans approaching 150 years. In the post‐dam era, invasive common carp are increasing in number while native bigmouth buffalo are declining. ABSTRACT The bigmouth buffalo Ictiobus cyprinellus

Assessing social behaviour between baleen whales (Mysticeti) and dolphins (Delphinidae)

Discover Animals
The dynamics and factors influencing interspecies interactions in the wild are not well understood, particularly among social marine animal species such as Mysticetes and Delphinadae.

Using spatial capture–recapture methods to estimate long‐term spatiotemporal variation of a wide‐ranging marine species

Ecography, Volume 2025, Issue 10, October 2025.
Determining population status to inform mitigation of anthropogenic threats requires statistical approaches that investigate spatial and temporal variation. In the face of climate change it is increasingly important to differentiate between changes in population size and redistributions of populations.
