Chloroform Fraction from Methanol Extract of Starfish Acanthaster planci Stimulates Catfish (Clarias sp.) Macrophage Immunomodulatory Activity

open access: yesJurnal Kelautan Tropis, 2023
Catfish (Clarias sp.) is Indonesia's most important and popular freshwater commodity, widely cultured and intensively grown. This study is aimed to find out the effects of the chloroform fraction from a methanol extract of Acanthaster planci on non ...

Non-Invasive Underwater DNA Sampling Illuminates Red Sea Echinoderm Diversity. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Species‐specific non‐invasive underwater DNA sampling remains largely understudied for marine invertebrates despite its potential to revolutionise biodiversity assessment of vulnerable species or fragile ecosystems. Comprehensive species‐specific DNA barcode databases are essential for accurate species identification and taxonomic assignment ...

The role of top-predator in the preservation of coral reefs ecosystem

open access: yesCommunication in Biomathematical Sciences, 2017
The coral reef ecosystem in Indonesian as part of Coral Triangle Region has been significantly decreasing in the last decades. This damage has been known widely due to coastal development, pollution, and uncontrolled fishing and harvesting.

Species and size diversity in protective services offered by coral guard-crabs [PDF]

open access: yesPeerJ, 2014
Coral guard-crabs in the genus Trapezia are well-documented defenders of their pocilloporid coral hosts against coral predators such as the Crown-of-Thorns seastar (Acanthaster planci complex).

Size matters: Predator outbreaks threaten foundation species in small Marine Protected Areas.

open access: yesPLoS ONE, 2017
The unanticipated impacts of consumers in fragmented habitats are frequently a challenge for ecosystem management. On Indo-Pacific coral reefs, crown-of-thorns sea stars (Acanthaster spp.) are coral predators whose outbreaks cause precipitous coral ...

Variation in Incidence and Severity of Injuries among Crown-of-Thorns Starfish (Acanthaster cf. solaris) on Australia’s Great Barrier Reef

open access: yesDiversity, 2017
Despite the presence of numerous sharp poisonous spines, adult crown-of-thorns starfish (CoTS) are vulnerable to predation, though the importance and rates of predation are generally unknown. This study explores variation in the incidence and severity of

Benthic Predators Influence Microhabitat Preferences and Settlement Success of Crown-of-Thorns Starfish (Acanthaster cf. solaris)

open access: yesDiversity, 2016
Like most coral reef organisms, crown-of-thorns starfish (Acanthaster spp.) are expected to be highly vulnerable to predation as they transition from a planktonic larval phase to settling among reef habitats.
