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

Comparative Genomics and Functional Evidence for Convergent Adaptation to Hypoxia in Mammals

Integrative Zoology, EarlyView.
This study reveals convergent selection in mammals adapted to hypoxia. Functional assays demonstrate that amino acid mutations reduce oxidative stress, attenuate hypoxia‐induced injury, and modulate the hypoxia‐inducible transcription factor (HIF)‐driven hypoxic response.

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.

The epizoic diatom Campylodiscus cf. clypeus (Bacillariophyta: Surirellaceae), a new symbiont of the Caribbean manatee in Mexico

Caldasia, 2018
Observations on the epizoic interaction between diatoms and marine mammals have been conducted mostly in cetaceans and are scarce in sirenians. By scraping the skin surface, the samples of biofilm were collected of a captive male Caribbean manatee in ...

The Digestive System of the Arctocephalus australis in Comparison to the Dog as a Land-Carnivore Model

Animals, 2022
Marine mammals play a critical ecological role as both predator and prey. They are divided into three groups that share similar adaptations to their aquatic life, but that have very different origins and life patterns: sirenians, pinnipeds, cetaceans ...

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

The Anatomical Record, Volume 309, Issue 8, Page 2124-2150, August 2026.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Effects of Simulated Herbivory on the Thermal Resilience of Two Temperate Seagrass Species

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study investigates how reduced leaf size via simulated herbivory influences the thermal performance of temperate seagrasses. Simulated herbivory enhanced physiological performance and resilience under elevated temperatures in Posidonia australis, but not in Heterozostera tasmanica.

Metagenomic Insights Into Red Sea Biodiversity Across the Web of Life

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Deep‐sequencing shotgun metagenomics of Red Sea benthic sediments reveals biodiversity across the web of life, from viruses to animals. Despite the strong dominance of prokaryotic DNA, low‐abundance eukaryotic reads capture broad taxonomic diversity. Open‐ocean communities are primarily structured by depth, whereas coastal eukaryotic communities follow

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab Achelous monspeliensis From Portugal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Crab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...
