CORAL REEF TRANSPLANT SUCCESS RATE IN BONETAMBU ISLAND, SPERMONDE ARCHIPELAGO

Jurnal Ilmu Kelautan Spermonde, 2023
The world's coral reefs are under threat from human activities through pollution and habitat changes. This condition is influenced by several factors, such as human activities and natural phenomena.

Status of Coral Reefs in the Water of Spermonde, Makassar, South Sulawesi [PDF]

E3S Web of Conferences, 2021
Observations of the condition of coral reefs have been carried out in Spermonde waters from 2015 to 2018. The method used in this observation uses Underwater Photo Transect (UPT), and the data obtained is analyzed using CPCe (Coral Point Count with Excel

Spectral index development for mapping live coral cover [PDF]

Journal of Applied Remote Sensing, 2013
Remotely sensed spectral indices are used in a range of environments for estimating properties of vegetation, soil, atmospheric, and water features. Here, the development of an index sensitive to the amount of live coral, using in situ spectral reflectance data from Australia and Hawaii is outlined.

Thermal Stress and Coral Cover as Drivers of Coral Disease Outbreaks

PLoS Biology, 2007
Very little is known about how environmental changes such as increasing temperature affect disease dynamics in the ocean, especially at large spatial scales. We asked whether the frequency of warm temperature anomalies is positively related to the frequency of coral disease across 1,500 km of Australia's Great Barrier Reef.

Disturbance and the dynamics of coral cover on the Great Barrier Reef (1995-2009).

PLoS ONE, 2011
Coral reef ecosystems worldwide are under pressure from chronic and acute stressors that threaten their continued existence. Most obvious among changes to reefs is loss of hard coral cover, but a precise multi-scale estimate of coral cover dynamics for ...

Environmental Variability and Threshold Model’s Predictions for Coral Reefs

Frontiers in Marine Science, 2021
Current models of the future of coral reefs rely on threshold (TM) and multivariate environmental variability models (VM) that vary in how they account for spatial and temporal environmental heterogeneity. Here, a VM based on General Additive Model (GAM)

Corals in Healthy Populations Produce More Larvae Per Unit Cover [PDF]

Conservation Letters, 2017
Abstract In coral reef conservation and management, the prevailing metric of reef health is percent coral cover, a measurement commonly used with the assumption that each unit of live coral tissue has equivalent ecological value. Here we show that the reproductive output of a coral population is not proportional to the cover of coral ...

Live Coral Cover Index Testing and Application with Hyperspectral Airborne Image Data

Remote Sensing, 2013
Coral reefs are complex, heterogeneous environments where it is common for the features of interest to be smaller than the spatial dimensions of imaging sensors. While the coverage of live coral at any point in time is a critical environmental management
