Mesophotic depths hide high coral cover communities in French Polynesia

Science of The Total Environment, 2022
The rapid decline of shallow coral reefs has increased the interest in the long-understudied mesophotic coral ecosystems (MCEs). However, MCEs are usually characterised by rather low to moderate scleractinian coral cover, with only a few descriptions of high coral cover at depth. Here, we explored eight islands across French Polynesia over a wide depth

The Mesophotic Coral Microbial Biosphere

2019
Dynamic symbioses between the host, photosynthetic eukaryotes, and diverse prokaryotes are the foundation of corals’ ecological successes across highly diverse ocean habitats. This may be especially so in mesophotic corals which face unique environmental challenges when compared to shallow-water corals, for example, light levels that drive ...

Investigating Fish‐Habitat Associations on Mesophotic Reefs Using Stereo‐BRUVS

Austral ecology (Print)
Fish‐habitat associations are fundamental ecological relationships characterising marine community assembly. The strength of fish‐habitat associations can be indicative of ecosystem resilience, making them important benchmarks for ecological monitoring ...

Mesophotic coral ecosystems in the Hawaiian Archipelago

Coral Reefs, 2010
Efforts to map coral reef ecosystems in the Hawaiian Archipelago using optical imagery have revealed the presence of numerous scleractinian, zoothanthellate coral reefs at depths of 30–130+ m, most of which were previously undiscovered. Such coral reefs and their associated communities have been recently defined as mesophotic coral ecosystems (MCEs ...

Contrasting Patterns of Connectivity Between Populations of Euphotic and Mesophotic Hydroids in Reunion Island Support the Deep Reef Refuge Hypothesis

Molecular Ecology
In the context of coral reef decline, mesophotic coral ecosystems (MCEs, 30–150 m) offer hope for the recovery of degraded euphotic reefs. The Deep Reef Refuge Hypothesis (DRRH) postulates the potential of mesophotic reefs to reseed euphotic reefs.

Mesophotic Coral Ecosystems: Introduction and Overview

2019
Although the existence of zooxanthellate corals in mesophotic coral ecosystems (MCEs; light-dependent coral ecosystems from 30 to 150 m in depth) has been known since the nineteenth century and focused scientific exploration of MCEs began over 50 years ago, more than 70% of all research on MCEs has been published only within the past seven years.

Caribbean mesophotic coral ecosystems are unlikely climate change refugia

Global Change Biology, 2016
AbstractDeeper coral reefs experience reduced temperatures and light and are often shielded from localized anthropogenic stressors such as pollution and fishing. The deep reef refugia hypothesis posits that light‐dependent stony coral species at deeper depths are buffered from thermal stress and will avoid bleaching‐related mass mortalities caused by ...

Modeling vertical coral connectivity and mesophotic refugia

Coral Reefs, 2015
Whether mesophotic reefs will behave as refugia for corals threatened by global climate change and coastal development depends on vertical exchange of larvae between diverse habitats. Here we use a biophysical model of larval dispersal to estimate vertical connectivity of a broadcasting (Orbicella faveolata) and a brooding (Porites astreoides) species ...

Sponges as Habitat Formers on Mesophotic, Soft-Substrate Seafloors of the Eastern Mediterranean

Journal of Marine Science and Engineering
This study aims to investigate the ecological role of sponges as habitat formers on soft-bottom habitats of the mesophotic zone. As habitat formers, sponges significantly enhance benthic habitat complexity and establish associations with a plethora of ...

Connectivity and stability of mesophotic coral reefs

Journal of Experimental Marine Biology and Ecology, 2011
Abstract Mesophotic coral ecosystems (MCEs), occurring at depths of 30 to over 150 m, represents the deep continuum of adjacent shallow coral reefs about which little is known. These reefs are most developed, and most frequently studied, in areas where light penetration is high and photosymbiotic reef-builders (corals) can persist as common members ...
