What can two years of monitoring tell us about Venezuelan coral reefs? The Southern Tropical America node of the Global Coral Reef Monitoring Network (STA-GCRMN)

Revista de Biología Tropical, 2010
In spite of their economic importance, coral reef communities of the world are rapidly decreasing, and an adequate management planification is needed. The benthic and fish communities of Dos Mosquises Sur and Madrizquí at Los Roques National Park, and ...

Switching between standard coral reef benthic monitoring protocols is complicated: proof of concept [PDF]

PeerJ, 2019
Monitoring the state of coral reefs is necessary to identify drivers of change and assess effectiveness of management actions. There are several widely-used survey methods, each of which is likely to exhibit different biases that should be quantified if ...

Coral reef benthic community changes in the Anthropocene: Biogeographic heterogeneity, overlooked configurations, and methodology

Global Change Biology, Volume 28, Issue 6, Page 1956-1971, March 2022., 2022
In coral reefs, changes towards communities dominated by other than hard corals are increasing in frequency, with severe impacts on the ecosystems. Here, we performed a systematic review and meta‐analysis to analyse the coral reef benthic community changes reported to date and discuss the advantages and limitations of the methods used. Our results show

The transformation of Caribbean coral communities since humans

Ecology and Evolution, Volume 11, Issue 15, Page 10098-10118, August 2021., 2021
We integrated paleoecological, historical, and modern survey data to track the prevalence of major coral species and life‐history groups throughout the Caribbean from the prehuman period to present. This extended time series reveals that Caribbean coral communities have been transformed via three distinct stages since humans: (a) declines in ...

The GCRMN - coordinating coral reef monitoring efforts for effective management [PDF]

Naga, 2004
The Global Coral Reef Monitoring Network (GCRMN) is an operational unit of the International Coral Reef Initiative (ICRI), established in 1995 and maintained by the Australian Institute of Marine Science (AIMS). The main responsibilities are to provide data and information on the global status of coral reefs, assess how people use and interact with ...

Essential ocean variables for global sustained observations of biodiversity and ecosystem changes

Global Change Biology, Volume 24, Issue 6, Page 2416-2433, June 2018., 2018
Biological essential ocean variables (EOVs) were identified based on their scientific and societal relevance and their feasibility for implementation in a global observing system. The process was based in a DPSIR model (drivers‐pressures‐state‐impact‐response): Drivers and pressures were identified from international conventions; the state of ocean ...

SIMAC: Development and implementation of a coral reef monitoring network in Colombia

Revista de Biología Tropical, 2010
Significant coral reef decline has been observed in Colombia during the last three decades. However, due to the lack of monitoring activities, most of the information about health and changes was fragmentary or inadequate.

Status and conservation of coral reefs in Costa Rica

Revista de Biología Tropical, 2010
Costa Rica has coral communities and reefs on the Caribbean coast and on the Pacific along the coast and off-shore islands. The Southern section of the Caribbean coast has fringing and patch reefs, carbonate banks, and an incipient algal ridge.

eDNA Collected by Custom‐Built Unmanned Surface Vehicles (USVs) Reveals Spatio‐Temporal Shifts in Tropical Coral Reef Faunal Communities

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Self‐constructed Unmanned Surface Vehicles were deployed at coral reefs on Reunion Island to capture environmental DNA (eDNA), identifying changes in animal communities depending on the time of day and sampling station. These findings suggest specific sites for high‐frequency, long‐term eDNA monitoring using low‐cost mobile devices.

A review of ecological risks of coral reef interventions

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Coral reefs, essential for biodiversity, livelihoods, and global economies, face severe threats from climate change and other stressors. Curbing greenhouse emissions is crucial, but the urgent situation also calls for immediate intervention strategies.
