Gradients in light, temperature and hydrodynamics associated with water depth are important determinants of ecological communities in marine environments. While depth specialism in coral reef fishes has been extensively studied in shallow (< 30 m) coastal reef systems, less is known about how depth-associated drivers operate over the larger depth ranges on isolated pinnacle and seamount reef systems, which are known to support abundant assemblages of predatory fishes. Using remotely operated vehicles, we surveyed predatory fish assemblages across a 100 m depth gradient on three seamount reefs in the Coral Sea.

Efficient detection and management of non-indigenous species are critical for mitigating their ecological impacts. Environmental DNA (eDNA) techniques have transformed biodiversity monitoring by enabling sensitive and cost-effective surveys. This study compares the efficacy of passive eDNA samplers (PEDS) to conventional active filtration methods for detecting the cryptogenic macroalga within the Papahānaumokuākea Marine National Monument, Hawai'i, USA.

The long-term development of coral reef frameworks and the net vertical accretion of reefs fundamentally underpins the provisioning of most reef-related ecosystem services. One area of particular concern at present is how rates of reef accretion are changing under ecological decline and what the consequences of this may be for the capacity of reefs to keep pace with near-future sea-level rise (SLR). This may have major implications for the capacity of reefs to maintain their coastal protective functions and to support reef island stability.

Coral reefs, vital marine ecosystems, face increasing threats from climate change and localized stressors like black sand deposits, yet their combined impacts are underexplored. This pioneering study investigates the synergistic effects of rising temperatures and black sand on reef-building corals in the Red Sea, Egypt, focusing on Stylophora pistillata and Acropora hyacinthus. Coral samples were collected from Hurghada and exposed to a three-day laboratory experiment involving thermal stress (31 °C), black sand (300 mg/L), nano black sand (300 mg/L), and combinations thereof.

The Darwin Mounds marine protected area has been afforded protection from bottom trawl fishing since August 2003, following the discovery of cold-water coral (CWC) communities in June 1998. Surveys of the area in 2000 provided evidence that deep-water trawling activities were impacting the corals, prompting the development of a conservation response. Here we report the most recent survey of these CWCs in 2019, contrasting those data with a prior survey in 2011, and the earliest observations in the area (1998-2000).
