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 ...

Cross‐Depth Genetic Connectivity Supports the Role of Deep Kelp Forests as Refuge From Climate Change

Diversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim Ocean warming and marine heatwaves are threatening the persistence of kelp forests, but cooler, deeper reefs might act as refuges from which shallow populations can recover. This study aimed to assess the genetic connectivity, diversity, and adaptive structure of deep kelp reefs to evaluate their potential as climate refuges.

Exploring the Biodiversity of Understudied Benthic Taxa at Mesophotic and Deeper Depths: Examples From the Order Zoantharia (Anthozoa: Hexacorallia)

Frontiers in Marine Science, 2019
Research on so-called “minor taxa” at mesophotic depths has lagged behind that of more commonly researched groups such as fish or hard corals. Exemplar taxa include species of the order Zoantharia, benthic colonial anemones that are cosmopolitan in ...

Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward

Fish and Fisheries, Volume 27, Issue 3, Page 607-626, May 2026.
ABSTRACT Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy.

Possible monitoring of mesophotic scleractinian corals using an underwater mini-ROV to sample coral eDNA

Royal Society Open Science
Mesophotic coral ecosystems (MCEs) are light-dependent tropical or subtropical communities occurring at depths of 30–150 m. Broader surveys of MCEs are needed to better understand stony corals, the keystone species of coral-reef ecosystems.

Illuminating Deep Reef Refugia: Horizontal and Vertical Genomic Connectivity of Seriatopora hystrix in the Ryukyu Islands, Japan

Molecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Shallow coral reefs are under threat from anthropogenic stress and climate change. Mesophotic coral ecosystems (MCEs), found in deeper, cooler and less impacted waters, are proposed as potential refugia or larval sources for shallow reefs. However, this hypothesis of such deep‐reef refugia is now controversial because their effectiveness is ...

Calcification and trophic responses of mesophotic reefs to carbonate chemistry variability

Frontiers in Marine Science
Mesophotic coral ecosystems (MCEs) are extensions of adjacent shallow water coral reefs. Accessibility to these ecosystems is challenging due to their depth limits (~ 30 – 150 m) and as a result, scientific knowledge of these reef systems is limited.

Reproductive biology of the deep brooding coral Seriatopora hystrix: Implications for shallow reef recovery.

PLoS ONE, 2017
Mesophotic coral ecosystems (MCEs, between 30 and 150 m depth) are hypothesized to contribute to the recovery of degraded shallow reefs through sexually produced larvae (referred to as Deep Reef Refuge Hypothesis).

Interacting Effects of Sea‐Level Rise and Ocean Warming Reshape Thermal Environments on a Coral Reef

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Sea‐level rise (SLR) alters nearshore hydrodynamics, yet its influence on coral reef thermal regimes under climate‐driven ocean warming remains poorly quantified. Using a fully coupled hydrodynamic–wave model validated at Palmyra Atoll, we isolate how SLR modifies temperature variability during a projected 2050 marine heatwave.

Fish ecology of mesophotic coral ecosystems

, 2017
Mesophotic coral ecosystems (MCEs; reefs 30-150 m depth) are largely unstudied. This thesis uses the shallow reef to MCE depth gradient around Utila, Honduras, to address research questions in three themes: (i) understanding fish community ecological processes on MCEs; (ii) evaluating effective survey techniques for MCE fish research; and (iii ...
