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 ...

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.

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 ...

Cameras or Divers? How Baited Remote Underwater Videos and ‘Long Swims’ Underwater Visual Census Complement Each Other on Coral Reefs

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study compares baited remote underwater videos (BRUV) and a rapid timed long swim (LS) UVC method to evaluate their ability in assessing relative abundance and diversity of large predatory reef fish from nine selected families. BRUVs were more effective in detecting mobile and bait‐attracted taxa such as Carangidae and recorded up to 28 unique ...

Effects of protection on large‐bodied reef fishes in the western Indian Ocean

Conservation Biology, Volume 39, Issue 4, August 2025.
Abstract Predatory and large‐bodied coral reef fishes have fundamental roles in the functioning and biodiversity of coral reef ecosystems, but their populations are declining, largely due to overexploitation in fisheries. These fishes include sharks, groupers, Humphead wrasse (Cheilinus undulatus), and Green Humphead parrotfish (Bolbometopon muricatum).

Conservation status and spatial patterns of AGRRA vitality indices in Southwestern Atlantic Reefs

Revista de Biología Tropical, 2010
Coral reefs along the Eastern Brazilian coast extend for a distance of 800km from 12° to 18°S. They are the largest and the richest reefs of Brazil coasts, and represent the Southernmost coral reefs of the Southwestern Atlantic Ocean.
