Corpses as Repositories of Information and Funerals as Information Centres: Why Natural Selection Favours the Bereaved

Ethology, EarlyView.
Corpses are repositories of information about the cause of death. The distress of the bereaved acts as an honest signal drawing conspecifics to the body, enabling them to learn quickly about the death, adapt their behaviour, and spread knowledge of threats across multiple social levels.

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

The Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Establishment and Characterization of a Primary Fibroblast Cell Culture from the Amazonian Manatee (Trichechus inunguis)

Animals
The vulnerable status of the Amazon manatee, Trichechus inunguis, indicates the need to seek measures to guarantee its conservation. In this context, the cultivation of cells in vitro is a strategy that should at least guarantee the preservation of their

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Avoidance failure, not detection failure drives gillnet bycatch in a small toothed whale: The harbour porpoise

Journal of Applied Ecology, Volume 63, Issue 10, October 2026.
Our findings suggest that bycatch is not simply due to a failure to detect nets but rather occurs when avoidance fails, highlighting the need for mitigation strategies that enhance detectability and support avoidance behaviour to overcome the global gillnet bycatch issue.

First Description of a Satellite DNA in Manatees’ Centromeric Regions

Frontiers in Genetics, 2021
Trichechus manatus and Trichechus inunguis are the two Sirenia species that occur in the Americas. Despite their increasing extinction risk, many aspects of their biology remain understudied, including the repetitive DNA fraction of their genomes.

Cool‐Water Dolphins Have Larger Appendages Than Warm‐Water Dolphins

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Endothermic marine mammals face significant thermoregulatory challenges due to heat loss in the highly conductive marine environment. Allen's rule states that endothermic animals in cold environments have smaller appendages than those in warmer environments.

Advancing Marine Mammal Conservation Through Omics Tools and Integration of Indigenous Ecological Knowledge

Molecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Conservation of biodiversity is a global priority as human‐driven pressures continue to intensify and alter ecosystems worldwide. Marine mammals are vulnerable species, facing numerous escalating anthropogenic threats. Here, we evaluate how, as omics technologies become more accessible and affordable, established and emerging tools are ...

Dental Complexity and Crown Relief Document Occlusal Wear Along the Tooth Row in West Indian Manatees

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Sirenians are a lineage of herbivorous marine mammals morphologically specialized for exploiting aquatic vegetation in shallow‐water habitats. In manatees (Trichechus), continuous horizontal tooth replacement may represent a solution for mitigating heavy dental wear incurred by a diet of abrasive plant material.

Marine mammal bycatch in gillnet and other entangling net fisheries, 1990 to 2011

Endangered Species Research, 2013
Since the 1970s the role of fishery bycatch as a factor reducing, or limiting the recovery of, marine mammal populations has been increasingly recognized.
