Outbreaks of adult Acanthaster planci (Linnaeus) have appeared at irregular intervals, arriving 3 yr after heavy rains (>100 cm in 3 months) following droughts (<25 cm in 4 months) or 3 yr after rains exceeding intensities of 30 cm in 24 h. Outbreaks of A. planci follow typhoons that bring heavy rains, but do not follow “dry” typhoons of equivalent wind force. Outbreaks occur around the high islands in Micronesia and Polynesia, but not around the atolls at intermediate locations. Phytoplankton… Expand
Localized outbreaks of Acanthaster planci at an isolated and unpopulated reef atoll in the Chagos Archipelago
TLDR
High densities of COTS were recently observed on reefs in the Chagos Archipelago, a remote group of atolls and banks within the central Indian Ocean, which experience very limited anthropogenic influence, which suggests that outbreaks may not be directly linked to guano nutrient enrichment. Expand
Management of crown-of-thorns sea star (Acanthaster planci L.) outbreaks: Removal success depends on reef topography and timing within the reproduction cycle
TLDR
Removals of crown-of-thorns sea stars are recommended to be performed in isolated reefs, where migration from adjacent areas is limited, and before reproduction in April (Northern hemisphere), reducing the chance of future outbreaks. Expand
History and dynamics of the crown-of-thorns starfish Acanthaster planci (L.) in the Suva area, Fiji
TLDR
It is demonstrated that there is no invariable pattern or process involved in the population dynamics of A. planci and that a single explanation of the A.planci phenomenon is therefore unlikely. Expand
Enhancement of Larval and Juvenile Survival and Recruitment in Acanthaster planci from the Effects of Terrestrial Runoff: a Review
TLDR
Current knowledge of the possible influence of components of terrestrial runoff on various stages in the life cycle of larval and juvenile A. planci is reviewed to suggest that elevated nutrient conditions exist in localized areas and that this may be caused by terrestrial runoff. Expand
Persistent and Transient Populations of the Crown-of-Thorns Starfish, Acanthaster Planci
TLDR
A simple model of the important processes influencing starfish population stability is developed and particular attention is drawn to the possible importance of persistent breeding populations of A. planci as sources of larvae initiating sequences of secondary outbreaks. Expand
Three lines of evidence to link outbreaks of the crown-of-thorns seastar Acanthaster planci to the release of larval food limitation
TLDR
Field data and the population model show that river floods and regional differences in phytoplankton availability are strongly related to spatial and temporal patterns in A. planci outbreaks on the Great Barrier Reef. Expand
Settlement and Recruitment of Acanthaster planci on the Great Barrier Reef: Questions of Process and Scale
TLDR
Evidence indicates strongly that the majority of outbreaks in the Great Barrier Reef system are secondary infestations as a result of water-borne transport and subsequent mass settlements of planktonic larvae seeded by other outbreak populations (and initially by populations undergoing primary outbreaks). Expand
Abundance and size structure of an Acanthaster planci population (Echinodermata: Asteroidea) in Sogod Bay, Southern Leyte, Philippines
TLDR
The distribution and population density of Acanthaster planci in Sogod Bay, Southern Leyte, Central Philippines was assessed and it is believed that the aggregation at Adrian Reef Marine Sanctuary is a form of foraging behavior at this time of the year and not a preparation for mass spawning. Expand
The crown-of-thorns starfish, Acanthaster planci, on the great barrier reef
TLDR
A range of modelling work on the Acanthaster phenomenon has been done, including non-spatial population models of the starfish and its predators and prey, spatial models of starfish aggregations and physical models of water circulation, i.e. larval transport models, at a range of spatial scales.

Ecological studies of the coral predator Acanthaster planci in the south pacific

Growth and recruitment of Acanthaster planci (L.) on the great barrier reef
TLDR
Size classes can be discerned in field size frequency data for Acanthaster planci which may be interpreted as age classes, which enables a possible field growth curve to be derived, which is consistent with measured growth data from the laboratory and from field experiments. Expand

Reproductive cycle of the green sea urchin, Strongylocentrotus droebachiensis
TLDR
The gonadal index cycle of the echinoid Strongylocentrotus droebachiensis is described from observations on the Atlantic and Pacific coasts of Canada, and an experimental study has confirmed that phytoplankton is the spawning cue. Expand
VARIATIONS IN TIME AND INTENSITY OF SETTING OF THE STARFISH, ASTERIAS FORBESI, IN LONG ISLAND SOUND DURING A TWENTY-FIVE-YEAR PERIOD
TLDR
Starfish commence spawning when water temperature reaches approximately 15° C., which usually occurs about the middle of June, but in some individuals spawning may continue into early September, and the average annual length of the setting period was about 52 days. Expand
GROWTH OF NORTHERN ANCHOVY, ENGRAULIS MORDAX, LARVAE IN THE SEA
Northern anchovy larvae from12 samples collected at 13.0'-16.2' C in the Southern California Bight were aged using daily growth increments in sagittal otoliths, and growth rates were calculated fromExpand
Phytoplankton as a stimulus for spawning in three marine invertebrates
TLDR
Evidence is given that the cue for spawning in these species is the spring phytoplankton bloom, and for species with planktotrophic larvae the synchronization of spawning with the phy toplankon bloom increases the probability of favourable food and temperature conditions for the development of the larvae and juveniles.

Effect of river outflow management on marine life
TLDR
Marine erosion of the Delta Coast has speeded-up following the Dam construction, due to loss of mud and silt deposition and loss of Lake-Sea currents, which can result in transgression of the sea on these lakes, and calls for urgent measures for shore protection. Expand
