A framework to quantify flow through coral reefs of varying coral cover and morphology. [PDF]

PLoS One, 2023
Flow velocities within coral reefs are greatly reduced relative to those at the water surface. The in-reef flow controls key processes that flush heat, cycle nutrients and transport sediment from the reef to adjacent beaches, all key considerations in assessments of reef resilience and restoration interventions.

Decadal stability in coral cover could mask hidden changes on reefs in the East Asian Seas [PDF]

Communications Biology, 2023
Coral reefs in the Central Indo-Pacific region comprise some of the most diverse and yet threatened marine habitats. While reef monitoring has grown throughout the region in recent years, studies of coral reef benthic cover remain limited in spatial and ...

Decline in coral cover and flattening of the reefs around Mauritius (1998–2010) [PDF]

PeerJ, 2018
Coral reefs are degrading through the impacts of multiple anthropogenic stressors. How are coral reef communities going to change and how to protect them for future generations are important conservation questions.

Depth and coral cover drive the distribution of a coral macroborer across two reef systems. [PDF]

PLoS One, 2018
Bioerosion, the removal of calcium carbonate from coral frameworks by living organisms, influences a variety of reef features, from their topographic complexity to the net balance of carbonate budgets. Little is known, however, about how macroborers, which bore into reef substrates leaving traces greater than 0.1 mm diameter, are distributed across ...

Density of coral larvae can influence settlement, post-settlement colony abundance and coral cover in larval restoration. [PDF]

Sci Rep, 2020
AbstractSuccessful recruitment of new individuals is essential for recovery of degraded coral reefs. Enhancing supply of coral larvae increases initial settlement, however post-settlement survival can be influenced by density-dependent processes. We investigated the influence of larval density on settlement, colony abundance and growth to 24 months for

Coral cover and species responses to heat exposure vary across contemporary Western Atlantic reefs [PDF]

Scientific Reports
Ocean warming threatens the persistence of tropical corals and the biologically diverse ecosystems they sustain. While field-based studies on heat impact have predominantly focused on quantifying coral bleaching, a symptom of thermal stress, less ...

Coral reef fish assemblages at Clipperton Atoll (Eastern Tropical Pacific) and their relationship with coral cover

Scientia Marina, 2016
Clipperton Atoll, one of the most isolated coral reefs worldwide, is of great scientific interest due to its geomorphology and high levels of endemism. This study explored the reef fish assemblage structure of Clipperton Atoll and its relationship with ...

High macroalgal cover and low coral recruitment undermines the potential resilience of the world's southernmost coral reef assemblages. [PDF]

PLoS ONE, 2011
Coral reefs are under increasing pressure from anthropogenic and climate-induced stressors. The ability of reefs to reassemble and regenerate after disturbances (i.e., resilience) is largely dependent on the capacity of herbivores to prevent macroalgal ...

Comparison of methods used to estimate coral cover in the Hawaiian Islands [PDF]

PeerJ, 2015
Nine coral survey methods were compared at ten sites in various reef habitats with different levels of coral cover in Kāne‘ohe Bay, O’ahu, Hawaiʻi. Mean estimated coverage at the different sites ranged from less than 10% cover to greater than 90% cover ...
