Environmental Status and Geomorphological Characterisation of Seven Black Coral Forests on the Sardinian Continental Shelf (NW Mediterranean Sea)

Biology, 2022
Marine animal forests are key mesophotic ecosystems that are under threat from increasing natural and human pressures. Despite the fact that various international agreements strive to preserve these fragile ecosystems, the environmental status of the ...

Ecological insights from environmental disturbances in mesophotic coral ecosystems [PDF]

Ecosphere, 2019
AbstractMesophotic coral ecosystems (MCEs) have historically been considered more stable than shallow reefs and thus suggested to provide refuge to coral reef communities against natural and anthropogenic impacts. Despite this assumption, a growing body of literature has shown that deep reefs are not immune to natural disturbance. Here, based on our in

In situ Estimation of Coral Recruitment Patterns From Shallow to Mesophotic Reefs Using an Optimized Fluorescence Imaging System

Frontiers in Marine Science, 2021
Coral recruitment represents a key element for coral reef persistence and resilience in the face of environmental disturbances. Studying coral recruitment patterns is fundamental for assessing reef health and implementing appropriate management ...

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.

Theme section on “Mesophotic Coral Ecosystems: Characterization, Ecology, and Management” [PDF]

Coral Reefs, 2010
Mesophotic coral ecosystems (MCEs) are characterized by the presence of light-dependent corals and associated communities that are typically found at depths ranging from 30 to 40 m and extending to over 150 m in tropical and subtropical regions. The dominant communities providing structural habitat in the mesophotic zone can be comprised of coral ...

Limited acclimation of early life stages of the coral Seriatopora hystrix from mesophotic depth to shallow reefs

Scientific Reports, 2022
Mesophotic coral ecosystems (MCEs, reefs between 30 and 150 m depth) have been hypothesized to contribute to shallow reef recovery through the recruitment of larvae. However, few studies have directly examined this.

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.

Diverse staghorn coral fauna on the mesophotic reefs of north-east Australia.

PLoS ONE, 2015
Concern for the future of reef-building corals in conditions of rising sea temperatures combined with recent technological advances has led to a renewed interest in documenting the biodiversity of mesophotic coral ecosystems (MCEs) and their potential to

Deep reefs are not refugium for shallow‐water fish communities in the southwestern Atlantic

Ecology and Evolution, 2021
The deep reef refugia hypothesis (DRRH) predicts that deep reef ecosystems may act as refugium for the biota of disturbed shallow waters. Because deep reefs are among the most understudied habitats on Earth, formal tests of the DRRH remain scarce. If the

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 ...
