A snapshot of reef conditions in North Ari Atoll (Maldives) following the 2016 bleaching event and Acanthaster planci outbreak

Marine and Freshwater Research, 2021
Coral reefs are degrading worldwide. This study explored the benthic community structure (biotic and abiotic benthic cover and coral composition) at three islands (Rasdhoo, Maayafushi and Vihamaafaru) in the central Maldivian archipelago, 2 years after ...

Field and Laboratory Observations of the Crown-of-Thorns Starfish, Acanthaster planci: Densities of Acanthaster planci in the Pacific Ocean

Nature, 1970
Although there have been many reports of the large scale destruction of Pacific coral reefs by the crown-of-thorns starfish, Acanthaster planci, little is known about the starfish's ecology and behaviour. We publish here reports of its population density in the Pacific Ocean, and studies of its locomotory and feeding behaviour in the laboratory.

Is Acanthaster planci an r-strategist?

Nature, 1978
THE debate over the cause of plagues of the crown-of-thorns starfish, Acanthaster planci, has been as long as the plagues themselves (for reviews see refs 1–3). Most recently, two lines of reasoning based on ecological concepts have been used to suggest that the causes of the population explosions should be sought in some abnormal event, and thus man ...

Haemodynamic and haematologic effects of Acanthaster planci venom in dogs

Toxicon, 1994
This study was designed to examine haemodynamic and haematologic effects of the crown-of-thorns starfish venom (Acanthaster planci venom: APV) in dogs. Severe systemic hypotension, thrombocytopenia and leukopenia were induced by APV (1.0 mg protein/kg i.v.), followed by gradual return to the baseline level within 60 min.

Biochemical stimuli for feeding in Acanthaster planci (L.)

Journal of Experimental Marine Biology and Ecology, 1976
Abstract The typical feeding response of the Crown of Thorns Starfish Acanthaster planci (L.) can be induced by mucoproteins of molecular weight greater than 200,000 daltons found in mucus obtained from corals of the genera Acropora and Fungia .

Spawning observation of Acanthaster planci in the Gulf of Thailand

Marine Biodiversity, 2014
The corallivorous Crown of Thorns starfish, Acanthaster planci, has contributed greatly to the decline of coral coverage in reefs throughout the Indo-Pacific region (reviewed in Pratchett et al. 2014). To date, little information is available on the reproductive timing and controlling factors for A.

Genomic organization of Hox and ParaHox clusters in the echinoderm, Acanthaster planci

Genesis, 2014
Summary: The organization of echinoderm Hox clusters is of interest due to the role that Hox genes play in deuterostome development and body plan organization, and the unique gene order of the Hox complex in the sea urchin Strongylocentrotus purpuratus ...

Bias in manta tow surveys of Acanthaster planci

Coral Reefs, 1990
To investigate the biases associated with manta tow surveys of Acanthaster planci, counts obtained by manta-towed observers were compared with counts made on SCUBA swims under a limited range of conditions. Five 10 m wide strip transects on different parts of two reefs and with different densities of A. planci were surveyed.

New Steroidal Glycosides from the Starfish Acanthaster planci

Chemistry of Natural Compounds, 2016
Two new and three known polyhydroxysteroid glycosides were isolated from the MeOH extract of the starfish Acanthaster planci. The structures of the isolated compounds were elucidated using NMR and mass spectrometry. The new glycosides had the same aglycon, (24S)-24-methyl-5α-cholestane-3β,4β,6α,8,15β,16β,28-heptaol, and different carbohydrate fragments,
