Photosynthesis and Bio-Optical Properties of Fluorescent Mesophotic Corals

Frontiers in Marine Science, 2021
Mesophotic coral ecosystems (MCEs) are light-dependent coral-associated communities found at 30–150 m depth. Corals inhabiting these deeper reefs are often acclimatized to a limited and blue-shifted light environment, enabling them to maintain the ...

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.

A comparison of mesophotic and shallow sponge holobionts resilience to predicted future temperature elevation

Frontiers in Marine Science, 2023
Climate change is predicted to have detrimental impacts on sessile invertebrates, including sponges. Mesophotic ecosystems have been suggested to play a major role as refugia for coral reef sponge species, however knowledge regarding the ability of ...

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.

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 ...

Black coral forests enhance taxonomic and functional distinctiveness of mesophotic fishes in an oceanic island: implications for biodiversity conservation

Scientific Reports, 2023
The degradation of shallow ecosystems has called for efforts to understand the biodiversity and functioning of Mesophotic Ecosystems. However, most empirical studies have been restricted to tropical regions and have majorly focused on taxonomic entities (

Theme section on mesophotic coral ecosystems: advances in knowledge and future perspectives [PDF]

Coral Reefs, 2016
The Second International Mesophotic Coral Ecosystems (MCEs) workshop was held in Eilat, Israel, October 26-31, 2014. Here we provide an account of: (1) advances in our knowledge of MCE ecology, including the central question of the potential vertical connectivity between MCEs and shallow-water reefs (SWRs), and that of the validity of the deep-reef ...

Mesophotic animal forests of the Aegean Sea support fish diversity hotspots under high fishing pressure

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Marine animal forests (MAFs) are dense aggregations of habitat‐forming species that constitute essential habitats for diverse taxa including fish. However, the study of MAFs and their associated fauna remains largely skewed to their shallowest occurrence, above 30 m depth.

Flow structures over mesophotic coral ecosystems in the eastern Gulf of Mexico

Continental Shelf Research, 2020
Abstract Simultaneous time series of current velocity profiles are used to characterize flow structures over intermediate-depth coral ecosystems in the eastern Gulf of Mexico. Understanding of temporal variability and spatial coherence in flow is necessary to establish connectivity among these ecosystems.

Light environment drives the shallow‐to‐mesophotic coral community transition

Ecosphere, 2019
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).
