Open AccesseDNA monitoring detects new outbreak wave of corallivorous seastar (Acanthaster cf. solaris) at Lizard Island, Great Barrier Reef
Crown-of-thorns seastar (CoTS, Acanthaster cf. solaris) outbreaks remain a significant cause of coral loss on the Great Barrier Reef (GBR) and across the West-Pacific Ocean. Previous outbreaks on the GBR have onl...

Open AccessThe crown-of-thorns seastar species complex: knowledge on the biology and ecology of five corallivorous Acanthaster species
Coral-eating crown-of-thorns seastars (CoTS, Acanthaster spp.) are major contributors to the coral reef crises across the Indo-Pacific region. Until recently, CoTS throughout the Indo-Pacific were regarded to be ...

Open AccessIncreasing densities of Pacific crown-of-thorns starfish (Acanthaster cf. solaris) at Lizard Island, northern Great Barrier Reef, resolved using a novel survey method
Recurrent population irruptions of Pacific crown-of-thorns starfish (CoTS, Acanthaster cf. solaris) are among the foremost causes of coral mortality on Australia’s Great Barrier Reef (GBR). Early intervention dur...

Article
Open AccessInduction of larval settlement in crown-of-thorns starfish is not mediated by conspecific cues
Population irruptions of crown-of-thorns starfish (COTS; Acanthaster spp.) remain a major cause of coral reef degradation throughout the Pacific and Indian Oceans and are inherently modulated by larval settlement...

Open AccessA test of adaptive strategy theory using fifteen years of change in coral abundance
Universal Adaptive Strategy Theory aims to predict how taxa and assemblages respond to disturbances on the basis of adaptive strategy group (ASG) membership. Here, we test such predictions using the adaptive s...

Open AccessResearch priorities for the sustainability of coral-rich western Pacific seascapes
Nearly a billion people depend on tropical seascapes. The need to ensure sustainable use of these vital areas is recognised, as one of 17 policy commitments made by world leaders, in Sustainable Development Go...

Open AccessImpacts of ocean warming on the settlement success and post-settlement survival of Pacific crown-of-thorns starfish (Acanthaster cf. solaris)
Ocean warming and population irruptions of crown-of-thorns starfish (CoTS; Acanthaster cf. solaris) are two of the greatest threats to coral reefs. As such, there is significant interest in understanding how CoTS...

Open AccessUsing size-weight relationships to estimate biomass of heavily targeted aquarium corals by Australia’s coral harvest fisheries
Coral reefs are highly threatened environs subject to ongoing unprecedented degradation as a result of anthropogenic activities. Given the existential threat to coral reef ecosystems, extractive industries tha...

Article
Frequent disturbances and chronic pressures constrain stony coral recovery on Florida’s Coral Reef
Acute disturbances and chronic pressures have an important and increasing influence on the structure of coral reef communities. For the viability of benthic taxa such as stony corals, a balance between loss fo...

Open AccessVariation in abundance, diversity and composition of coral reef fishes with increasing depth at a submerged shoal in the northern Great Barrier Reef
Coral reef fishes often exhibit specific or restricted depth distributions, but the factors (biotic or abiotic) that influence patterns of depth use are largely unknown. Given inherent biological gradients wit...

Article
Open AccessEffects of elevated temperature on the performance and survival of pacific crown-of-thorns starfish (Acanthaster cf. solaris)
Population irruptions of Pacific crown-of-thorns starfish (Acanthaster cf. solaris) have caused substantial damage to coral reefs, but it is largely unknown how this asteroid will fare in a warmer ocean. We expos...

Article
Open AccessDangerous demographics in post-bleach corals reveal boom-bust versus protracted declines
Thermal-stress events have changed the structure, biodiversity, and functioning of coral reefs. But how these disturbances affect the dynamics of individual coral colonies remains unclear. By tracking the fate...

Article
Reproductive investment and fecundity of Pacific crown-of-thorns starfish (Acanthaster cf. solaris) on the Great Barrier Reef
Crown-of-thorns starfish (Acanthaster spp.) is reported to have exceptional reproductive capacity, but this has been largely inferred based on the overall weight of gonads (and mostly for females), and there are ...

Article
Limited genetic signal from potential cloning and selfing within wild populations of coral-eating crown-of-thorns seastars (Acanthaster cf. solaris)
Population outbreaks of crown-of-thorns seastars (CoTS; Acanthaster spp.) are contributing to extensive coral loss and reef degradation throughout the Indo-Pacific, but the causes and underlying mechanisms of pop...

Article
Temporal variability in gametogenesis and spawning patterns of crown-of-thorns starfish within the outbreak initiation zone in the northern Great Barrier Reef
Population outbreaks of the coral-eating crown-of-thorns starfish (CoTS) have resulted in extensive coral mortality on reefs in the Indo-Pacific region and is considered one of the major contributors of signif...

Territoriality and condition of chevron butterflyfish (Chaetodon trifascialis) with varying coral cover on the great barrier reef, Australia
The chevron butterflyfish, Chaetodon trifascialis, is among the most specialised coral-feeding fish, and while it is known to be very susceptible to extensive depletion of its preferred coral prey (tabular Acropo...

Chapter
Recurrent Mass-Bleaching and the Potential for Ecosystem Collapse on Australia’s Great Barrier Reef
Coral reefs are extremely vulnerable to human-induced climate change. Most notably, increasing ocean temperatures are causing increasing incidence and severity of mass coral bleaching. There have been three ma...

Keep your friends close and your anemones closer – ecology of the endemic wideband anemonefish, Amphiprion latezonatus
Endemic marine species often exist as metapopulations distributed across several discrete locations, such that their extinction risk is dependent upon population dynamics and persistence at each location. The ...

Open AccessSize-specific recolonization success by coral-dwelling damselfishes moderates resilience to habitat loss
Increasing degradation of coral reef ecosystems and specifically, loss of corals is causing significant and widespread declines in the abundance of coral reef fishes, but the proximate cause(s) of these declin...
