An Overview of Aplysinopsins: Synthesis and Biological Activities

open access: yesMarine Drugs, 2023
Marine products are among the most promising sources of biologically active molecules. Aplysinopsins, tryptophan-derived marine natural products, were isolated from different natural marine sources including sponges, stony corals (hard corals) especially

Borneo coral reefs subject to high sediment loads show evidence of resilience to various environmental stressors [PDF]

open access: yes, 2019
For reefs in South East Asia the synergistic effects of rapid land development, insufficient environmental policies and a lack of enforcement has led to poor water quality and compromised coral health from increased sediment and pollution.

Peroxynitrite Generation and Increased Heterotrophic Capacity Are Linked to the Disruption of the Coral–Dinoflagellate Symbiosis in a Scleractinian and Hydrocoral Species

open access: yesMicroorganisms, 2019
Ocean warming is one of the greatest global threats to coral reef ecosystems; it leads to the disruption of the coral–dinoflagellate symbiosis (bleaching) and to nutrient starvation, because corals mostly rely on autotrophy (i.e., the supply of ...

Impacts of stratospheric aerosol geoengineering strategy on Caribbean coral reefs [PDF]

open access: yes, 2017
Purpose: Currently, negotiation on global carbon emissions reduction is very difficult due to lack of international willingness. In response, geoengineering (climate engineering) strategy is proposed to artificially cool the planet.

The influence of seawater pH on U / Ca ratios in the scleractinian cold-water coral Lophelia pertusa [PDF]

open access: yes, 2014
The increasing pCO2 in seawater is a serious threat for marine calcifiers and alters the biogeochemistry of the ocean. Therefore, the reconstruction of past-seawater properties and their impact on marine ecosystems is an important way to investigate the ...

Oxygen and heterotrophy affect calcification of the scleractinian coral Galaxea fascicularis. [PDF]

open access: yesPLoS ONE, 2012
Heterotrophy is known to stimulate calcification of scleractinian corals, possibly through enhanced organic matrix synthesis and photosynthesis, and increased supply of metabolic DIC.

Shallow-water hard corals (Hexacorallia: Scleractinia) from Bangka Belitung Islands Waters, Indonesia

open access: yesAceh Journal of Animal Science, 2019
Bangka Belitung Islands (Sumatra, Indonesia) has various coastal resources, e.g., coral reefs, seagrass beds, mangrove forests. However, the coral community has been threatened by anthropogenic activities, i.e., tin mining and illegal tin mining ...

The reproductive season of scleractinian corals in Socotra, Yemen [v1; ref status: indexed, http://f1000r.es/36f]

open access: yesF1000Research, 2014
Determining when corals reproduce has clear management and economic implications. Here we document the reproductive condition of corals in the genus Acropora on the island of Socotra in Yemen during February 2014.
