Echoes of Evolution in Holocentridae: Harmony Between Phylogeny, Morphology and Acoustics

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Using phylogenetic, morphological, and acoustic data from 53 species, we reconstructed the evolution of acoustic communication in nocturnal reef fishes of the family Holocentridae. Our results reveal two major clades with distinct sound‐producing morphologies and acoustic features, and suggest a three‐step diversification process involving the ...

Metagenomic Insights Into Red Sea Biodiversity Across the Web of Life

open access: yesEnvironmental 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

Learning capacities and welfare in an Antillean manatee, Trichechus manatus manatus

open access: yesComptes Rendus Biologies, 2020
Studies on the cognitive abilities of manatees are limited despite their importance for the environmental enrichment and welfare of individuals in captivity and the understanding of manatee behaviour in the wild.

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

open access: yesZoo Biology, Volume 45, Issue 4, Page 435-443, July/August 2026.
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.

Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

Linking Use of Ship Channels by West Indian Manatees (Trichechus manatus) to Seasonal Migration and Habitat Use

open access: yesFrontiers in Marine Science, 2019
Research on marine mammal occurrence in ship channels often focuses on large cetaceans in offshore shipping routes, while nearshore research largely addresses small vessel strikes.
