The role of viruses in coral health and disease [PDF]

open access: yesJournal of Invertebrate Pathology, 2017
Metagenomic and electron microscopy studies confirm that the coral microbiome contains a rich diversity and abundance of viruses. While there have been no definitive tests of disease causation by viruses in corals, viruses have been implicated as coral pathogens in a number of studies.

Human impact on atolls leads to coral loss and community homogenisation : a modeling study [PDF]

open access: yes, 2012
We explore impacts on pristine atolls subjected to anthropogenic near-field (human habitation) and far-field (climate and environmental change) pressure.

ANTI-BACTERIAL PROPERTY OF A CORAL-ASSOCIATED BACTERIUM Bacillus sp. AGAINST CORAL PATHOGENIC [PDF]

open access: yes, 2006
Marine organisms such as corals are frequently colonized by bacteria that may be pathogenic to them. One of the means by which they are able to combat microbial attack is by chemical defense.

MAFFN_YOLOv5: Multi-Scale Attention Feature Fusion Network on the YOLOv5 Model for the Health Detection of Coral-Reefs Using a Built-In Benchmark Dataset

open access: yesAnalytics, 2023
Coral-reefs are a significant species in marine life, which are affected by multiple diseases due to the stress and variation in heat under the impact of the ocean.

Coral-bacterial communities before and after a coral mass spawning event on Ningaloo Reef [PDF]

open access: yes, 2012
Bacteria associated with three coral species, Acropora tenuis, Pocillopora damicornis and Tubastrea faulkneri, were assessed before and after coral mass spawning on Ningaloo Reef in Western Australia.

Growth anomalies on the coral genera Acropora and Porites are strongly associated with host density and human population size across the Indo-Pacific. [PDF]

open access: yesPLoS ONE, 2011
Growth anomalies (GAs) are common, tumor-like diseases that can cause significant morbidity and decreased fecundity in the major Indo-Pacific reef-building coral genera, Acropora and Porites.

First Report of Potential Coral Disease in the Coral Hatchery of Thailand [PDF]

open access: yesDiversity, 2021
In this study, coral disease was first reported in the coral hatchery in Thailand. Disease were usually found on corals aged two to five years old during the months of November to December of each year. To identify bacterial strains, culture-based methods for strain isolation and molecular techniques of the 16S rRNA gene analysis were used.

Baseline reef health surveys at Bangka Island (North Sulawesi, Indonesia) reveal new threats [PDF]

open access: yesPeerJ, 2016
Worldwide coral reef decline appears to be accompanied by an increase in the spread of hard coral diseases. However, whether this is the result of increased direct and indirect human disturbances and/or an increase in natural stresses remains poorly ...

Biogeography and change among regional coral communities across the western Indian Ocean [PDF]

open access: yes, 2014
Coral reefs are biodiverse ecosystems structured by abiotic and biotic factors operating across many spatial scales. Regional-scale interactions between climate change, biogeography and fisheries management remain poorly understood.

Status of Coral Health and Disease in Kessilampe Waters, Kendari, South East Sulawesi

open access: yesIlmu Kelautan, 2018
Diseases of coral reef organisms have become a global threat to coral reefs and a major cause of reef deterioration. The presence of coral diseases influence marine resources productivity that interact with coral reefs. The purpose of this research is to
