Half a century of echinoid population decline in the northern Gulf of Aqaba, Red Sea

Journal of Animal Ecology, Volume 95, Issue 3, Page 443-454, March 2026.
Multi‐decadal monitoring in the Gulf of Aqaba, northern Red Sea, reveals severe (>90%) declines of key echinoid grazers. These declines signify a collapse of crucial herbivory functions underpinning coral reef resilience. Results implicate accelerating anthropogenic stress as a principal driver, emphasizing the urgent need for sustained, species ...

Rapid Evolution in a Coral Population Following a Mass Mortality Event

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Globally, corals face an increased frequency of mass mortality events (MMEs) as populations experience repeated marine heatwaves which disrupt their obligate algal symbiosis. Despite greater occurrences of MMEs, the relative roles of the environment, host, and symbiont genetic variation in survival, subsequent recovery, and carry‐over effects ...

Violapyrones H and I, New Cytotoxic Compounds Isolated from Streptomyces sp. Associated with the Marine Starfish Acanthaster planci

Marine Drugs, 2014
Two new α-pyrone derivatives, violapyrones H (1) and I (2), along with known violapyrones B (3) and C (4) were isolated from the fermentation broth of a marine actinomycete Streptomyces sp.

Non‐Invasive Underwater DNA Sampling Illuminates Red Sea Echinoderm Diversity

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
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 ...

Coral Venom and Toxins as Protection Against Crown‐of‐Thorns Sea Star Attack

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Crown‐of‐thorns sea star (CoTS) outbreaks are a main cause of hard coral cover decline across the Indo‐Pacific, posing a major threat to the resilience of coral reefs. However, the drivers underlying CoTS feeding on preferred (e.g., Acropora species) versus non‐preferred (e.g., Porites species) are poorly understood. We hypothesised that coral

Active control of the visual field in the starfish Acanthaster planci

Vision Research, 2016
Photoreception in echinoderms has been studied for several years with a focus on the dermal photoreceptors of echinoids. Even though spatial vision has been proposed for this dermal photosystem, by far the most advanced system is found in a number of asteroids where an unpaired tube foot at the tip of each arm carries a proper eye, also known as the ...

Joint estimation of crown of thorns (Acanthaster planci) densities on the Great Barrier Reef [PDF]

PeerJ, 2016
Crown-of-thorns starfish (CoTS; Acanthaster spp.) are an outbreaking pest among many Indo-Pacific coral reefs that cause substantial ecological and economic damage.

Genetic Evidence of Multiple and Diverse Range Expansion Events From an Outbreak of the Crown‐of‐Thorns Seastar, Acanthaster Cf. Solaris on a Subtropical Reef

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study examines the population genetics of a Crown of Thorns seastar (Acanthaster cf. solaris) outbreak on a subtropical coral reef. We demonstrate that this population originated from larval connectivity via the East Australian Current from the Great Barrier Reef, with high genomic connectivity indicating substantial risk of future outbreaks as ...
