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.

Enhancing Brain Segmentation in MRI through Integration of Hidden Markov Random Field Model and Whale Optimization Algorithm

Computers
The automatic delineation and segmentation of the brain tissues from Magnetic Resonance Images (MRIs) is a great challenge in the medical context. The difficulty of this task arises out of the similar visual appearance of neighboring brain structures in ...

Myths, Furphies and Red Herrings Associated With Dingo Ecology and Management

Ecological Management &Restoration, Volume 27, Issue 3, September 2026.
ABSTRACT Variability in the inferential strength or reliability of different scientific studies creates uncertainty in the status of knowledge on a given subject, giving rise to multiple myths, furphies and red herrings in scientific discourse. This is particularly true in the case of dingo ecology and management in Australia, which exemplifies common ...

High Cost and Low Trust: Insights From Qualitative Commercial Fishing Cost Data in the Northeast United States

Fisheries Management and Ecology, Volume 33, Issue 4, Page 665-680, August 2026.
ABSTRACT In fisheries management, socioeconomic data, specifically qualitative data analysis, is often underutilized. This study qualitatively analyzed a primary federal data collection effort in the Northeast United States, The Greater Atlantic Region Commercial Fishing Business Cost Survey.

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, Volume 33, Issue 4, Page 719-732, August 2026.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

The Foe You Know: Observations of Interspecific Interactions Between Small Cetaceans and Northern Resident Killer Whales (Orcinus orca) in the Northeast Pacific

Ecology and Evolution
We documented the first aerial observations of interspecific interactions of fish‐eating, northern resident killer whales (Orcinus orca) with two small cetacean species, Dall's porpoises (Phocoenoides dalli) and Pacific white‐sided dolphins ...

Menopause Averted a Midlife Energetic Crisis With Help From Older Dependent Children and Parents: A Simulation Study

American Journal of Biological Anthropology, Volume 190, Issue 3, July 2026.
ABSTRACT Objectives The grandmother hypothesis proposes that ancestral women ceased reproduction midlife to instead provision their grandchildren. An alternative “two‐sex” account proposes that the high energetic burden of caring for slow‐developing offspring was met with biparental investment.

Global Patterns and Drivers of Climate Vulnerability in Sharks and Rays: A Reassessment Using the IRACC Framework

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Climate vulnerability in sharks and rays is unevenly distributed across habitats and ecological groups, reflecting differences in exposure pathways and biological constraints. Using an updated application of the Integrated Risk Assessment for Climate Change (IRACC) framework, we conducted a global reassessment of climate vulnerability for 95 ...
