In situ observation of bluntnose sixgill shark (Hexanchus griseus) aggregation, mainland Palau

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract The bluntnose sixgill shark (Hexanchus griseus) is a globally distributed large‐bodied predator, primarily associated with deep‐sea environments. Due to the logistical constraints of its habitat, much remains unknown about the life history and behavior of H. griseus.

Species‐Specific Vulnerability of Northern Red Sea Mesophotic Corals to Accelerated Warming

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Mesophotic reefs are often considered climate refuges, yet experimental thermal‐stress reveals species‐dependent vulnerability. Skeletal optics, energy reserves, and light environment determine bleaching severity. A depth‐generalist coral resisted stress while the mesophotic specialist bleached severely.

From cells to reefs—fluorescent protein distribution reveals species‐specific photoadaptation in closely related Caribbean corals

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Fluorescent proteins (FPs) are diverse and widespread pigments in reef‐building corals, assumed to modulate the internal light microenvironment within coral tissues. Yet, their precise distribution and organization at the tissue and cellular levels remain poorly understood, limiting our understanding of their functional roles.

Temperate mesophotic ecosystems: gaps and perspectives of an emerging conservation challenge for the Mediterranean Sea

The European Zoological Journal, 2019
Mesophotic habitats, hosting benthic assemblages totally unknown and unexpected in the early 2000s, are attracting an increasing interest from scientists.

Offshore Neopycnodonte Oyster Reefs in the Mediterranean Sea

Diversity, 2020
Oysters are important ecosystem engineers best known to produce large bioconstructions at shallow depth, whilst offshore deep-subtidal oyster reefs are less widely known.

Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Structure of Mesophotic Reef Fish Assemblages in the Northwestern Hawaiian Islands.

PLoS ONE, 2016
Mesophotic coral ecosystems (MCEs) support diverse communities of marine organisms with changes in community structure occurring along a depth gradient. In recent years, MCEs have gained attention due to their depths that provide protection from natural ...

eDNA signals improve local predictions of fish abundances in Mediterranean coastal ecosystems

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
This study demonstrates that integrating eDNA metabarcoding data into species distribution models can improve fish abundance predictions, especially for site‐attached and reef‐associated species. This approach provides a scalable and cost‐effective tool for monitoring, impact assessment, spatial planning and adaptive management of marine resources ...

First Report of Endolithic Members of Rhodosorus marinus (Stylonematales, Rhodophyta) Growing Inside Rhodoliths Offshore Louisiana, Northwestern Gulf of Mexico

Frontiers in Marine Science, 2020
Endolithic, red unicells residing in the interior of Lithothamnion rhodoliths, collected offshore the NW Gulf of Mexico in mesophotic rhodolith beds at ∼54–55 m depth and maintained in closed microcosms, were used to establish cultures following their ...

Projected Risks to Biodiversity Conservation Along Brazil's Equatorial Margin Under Expanding Offshore Oil Development

Conservation Letters, Volume 19, Issue 3, May/June 2026.
ABSTRACT Brazil's Equatorial Margin is one of the least studied yet most ecologically significant regions of the Atlantic Ocean. Encompassing the Amazon coast, the region is entering a new phase of industrial expansion. In 2025, Brazil issued its first offshore oil exploration license in two decades, opening the door to large‐scale hydrocarbon ...
