Regional decline of coral cover in the Indo-Pacific: timing, extent, and subregional comparisons. [PDF]

PLoS ONE, 2007
A number of factors have recently caused mass coral mortality events in all of the world's tropical oceans. However, little is known about the timing, rate or spatial variability of the loss of reef-building corals, especially in the Indo-Pacific, which ...

Other faunas, coral rubbles, and soft coral covers are important predictors of coral reef fish diversity, abundance, and biomass

Fisheries and Aquatic Sciences, 2023
Coral reef fisheries are prominent for the archipelagic countries’ food sufficiency and security. Studies showed that fish abundance and biomass are affected by biophysical variables. The present study determines which biophysical variables are important predictors of fish diversity, abundance, and biomass. The study used available monitoring data from

Coral recruitment and its relationship to hard coral cover in the Derawan Islands, East Kalimantan

IOP Conference Series: Earth and Environmental Science, 2023
Abstract Coral recruitment is the process when coral larvae settle to the substrate and establish themselves as a reef community. The success of coral recruitment is very important for the sustainability of coral reefs in an area, including the Derawan Islands which develop underwater tourism.

Severe Heat Stress Resulted in High Coral Mortality on Maldivian Reefs following the 2015–2016 El Niño Event

Oceans, 2021
Coral cover worldwide has been declining due to heat stress caused by climate change. Here we report the impacts of the 2015–2016 El Niño mass coral bleaching event on the coral cover of reefs located on central and northern atolls of the Maldives.

Percentage of Hard Coral Cover and Coral Recruitment on in Bangsring Beach, Banyuwangi Regency

Research Journal of Life Science, 2023
One of the tourist attractions at Bangsring Beach is the condition of the coral reef ecosystem and unique marine biota that tourists can enjoy by snorkeling and diving. Based on research (Ekawati et al., 2021) using remote sensing, the area of live coral reefs on Bangsring Beach is as follows; 2005; 3.38, 2008; 2.61, 2011; 3.7, 2017; 3.98, 2020; 6.1 Ha)

Viral predation pressure on coral reefs

BMC Biology, 2023
Background Predation pressure and herbivory exert cascading effects on coral reef health and stability. However, the extent of these cascading effects can vary considerably across space and time.

Resistance and resilience of a coral reef fish community to changes in coral cover [PDF]

Marine Ecology Progress Series, 2008
Coral reefs are being degraded worldwide by perturbations that range from local distur- bances to large-scale climate forcing. To gain insight into possible responses of the fish community to losses of live coral, we surveyed large plots that represented the range in cover of live coral in lagoons of Moorea, French Polynesia, to explore relationships ...

Cold water and harmful algal blooms linked to coral reef collapse in the Eastern Tropical Pacific [PDF]

PeerJ, 2022
Background With conventional coral reef conservation methods proving ineffective against intensifying climate change, efforts have focussed on augmenting coral tolerance to warmer water—the primary driver of coral declines.

Growing coral larger and faster: micro-colony-fusion as a strategy for accelerating coral cover

PeerJ, 2015
Fusion is an important life history strategy for clonal organisms to increase access to shared resources, to compete for space, and to recover from disturbance. For reef building corals, fragmentation and colony fusion are key components of resilience to disturbance. Observations of small fragments spreading tissue and fusing over artificial substrates
