First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

Zoo Biology, EarlyView.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

Social information about others' affective states in a human‐altered world

Journal of Animal Ecology, EarlyView.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Animal translations: AI and the intelligibility of non‐human worlds Traduire l'animal : l'IA et l'intelligibilité des mondes non humains

Journal of the Royal Anthropological Institute, EarlyView.
Amid the general sense of worry that large language models will soon drown out human voices, some researchers are optimistic that machine learning will allow humans to listen to and understand animal voices to an unprecedented extent. As part of a broader project aimed at interspecies communication, a loosely connected set of animal behaviourists, AI ...

Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

Integrative Zoology, EarlyView.
This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Subsurface Behaviors of Hector's Dolphins Could Increase Their Risk of Bycatch

Conservation Letters
Hector's dolphins, endemic to New Zealand, suffer from bycatch in fishing gear. Fishing restrictions in inshore areas have reduced bycatch, although dolphins have been recorded outside these areas.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects

Andrology, EarlyView.
ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.
