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.

Is Gillnet Prey Subsidizing Ontogenetic Diet Shifts and Early Weaning in Common Coastal Bottlenose Dolphins From the Southwestern Gulf of Mexico?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Artisanal gillnet fisheries can concentrate prey and provide incidental food subsidies to marine predators, but their effects on early‐life foraging behavior and demography remain poorly resolved. The Alvarado bottlenose dolphin population that lives off the coast of Veracruz, Mexico, is well known for having chronic, frequent, and recurring ...

Spatial-based management for cetacean conservation: a Portuguese coast case study

Frontiers in Marine Science
Cetaceans are critical indicators of ecosystem health, yet face significant threats from overfishing, habitat loss, and climate change. Key conservation strategies in the EU include Marine Protected Areas (MPAs), the Natura 2000 network, and Important ...

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Application of DNA Methylation–Based Age Estimation to Construct an Age Structure of Humpback Whales in a Newly Emerged Wintering Ground Around Hachijojima Island, Tokyo Metropolis, Japan

Ecology and Evolution
Using a noninvasive DNA methylation (DNAm)–based age estimation method, we investigate the age structure of humpback whales that newly emerged around Hachijojima Island, Tokyo Metropolis, Japan to uncover the role of this area for this species.

Navigating morphometric minefields: Modelling heteroscedasticity in length‐conversion models

Journal of Fish Biology, EarlyView.
Abstract A common problem when combining data on species' traits from multiple sources is that researchers often measure the same trait in different ways. For example, the length of a shark can be measured in a straight‐line or over‐the‐body, and for lengths that include the tail (e.g., fork and total lengths), with the tail in ‘stretched’ or ‘natural’

Cetacean Stranding Response Program and Spatial–Temporal Analysis in Taiwan, 1994–2018

Animals
A national cetacean stranding response program in Taiwan has evolved significantly in the past three decades. Initially co-ordinated by National Taiwan University from 1994, the program transitioned to the Taiwan Cetacean Society in 1999, and local ...

Isolation and Identification of Erysipelothrix sp. in Hybrid Grouper (Epinephelus fuscoguttatus × E. lanceolatus) in Taiwan

Journal of Fish Diseases, EarlyView.
ABSTRACT In February 2025, a mortality event of unknown aetiology occurred at a hybrid grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) aquaculture farm in southern Taiwan, with sporadic daily deaths persisting for a month. Four moribund groupers were collected over three sampling intervals for diagnostic investigation.

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

Journal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

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.
