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.

Mesophotic coral communities escape thermal coral bleaching in French Polynesia

Royal Society Open Science, 2021
Climate change and consequent coral bleaching are causing the disappearance of reef-building corals worldwide. While bleaching episodes significantly impact shallow waters, little is known about their impact on mesophotic coral communities.

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.

Habitat heterogeneity reflected in mesophotic reef sediments [PDF]

Sedimentary Geology, 2015
Abstract Modern reef sediments reflect the physical and chemical characteristics of the environment as well as the local reef fauna. Analysis of sedimentary reef facies can thus provide a powerful tool in interpreting ancient reef deposits. However, few studies have attempted to differentiate sedimentary facies in mesophotic coral ecosystems, low ...

Taking a deeper look: Quantifying the differences in fish assemblages between shallow and mesophotic temperate rocky reefs.

PLoS ONE, 2019
The spatial distribution of a species assemblage is often determined by habitat and climate. In the marine environment, depth can become an important factor as declining light and water temperature leads to changes in the biological habitat structure. To

Sponges in a Changing Climate: Survival of Agelas oroides in a Warming Mediterranean Sea

Frontiers in Marine Science, 2020
Sponges hold a key role in benthic environments, and specifically in the Mediterranean Sea. Past events of mass mortality in sponge communities have been linked to extended periods of high-temperature anomalies, yet it is unknown how a gradual change ...

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.

Light environment drives the shallow to mesophotic coral community transition [PDF]

Ecosphere, 2019
Abstract Light quality is a crucial physical factor driving coral distribution along depth gradients. Currently, a 30 m depth limit, based on SCUBA regulations, separates shallow and deep mesophotic coral ecosystems (MCEs).

Hidden in the deep: Distinct benthic trajectories call for monitoring of mesophotic reefs

Conservation Letters, 2022
Coral reef conservation management depends on long‐term monitoring efforts for a sound understanding of ecosystem structuring, functioning, and dynamics.

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 ...
