Environmental and biological cues for spawning in the crown-of-thorns starfish
Sporadic outbreaks of the coral-eating crown-of-thorns starfish are likely to be due, at least in part, to spatial and temporal variation in reproductive and settlement success. For gonochoric and broadcast spawning species such as crown-of-thorns starfish, spawning synchrony is fundamental for achieving high rates of fertilization. Highly synchronized gamete release within and among distinct p...

Figure 1. Crown-of-thorns starfish and their legacy. (A) A group of crown-of-thorns starfish converge on the remaining small piece of living coral tissue (lc) on the surface of a tabular coral (Acropora sp.) The other coral tissue has just been consumed by the starfish so that only the white skeleton remains (cs). (B) After crown-of-thorns starfish have removed the living coral tissue, the expo...
متن کاملModel to manage and reduce crown-of-thorns starfish outbreaks
The crown-of-thorns starfish (COTS) Acanthaster planci is one of the largest causes of coral cover loss on Australia’s Great Barrier Reef. Numerous trophic-mediated and anthropogenic-related hypotheses, singly or in combination, have been proposed to explain COTS outbreaks, but the evidence remains inconclusive. There is, however, an urgent need for effective control and mitigation strategies. ...
متن کاملInteractive Effects of Endogenous and Exogenous Nutrition on Larval Development for Crown-Of-Thorns Starfish
Outbreaks of crown-of-thorns starfish are often attributed to step-changes in larval survivorship following anomalous increases in nutrients and food availability. However, larval growth and development is also influenced by the nutritional condition of spawning females, such that maternal provisioning may offset limitations imposed by limited access to exogenous sources of nutrients during the...
متن کاملPhylogeography of the Crown-of-Thorns Starfish in the Indian Ocean
BACKGROUND Understanding the limits and population dynamics of closely related sibling species in the marine realm is particularly relevant in organisms that require management. The crown-of-thorns starfish Acanthaster planci, recently shown to be a species complex of at least four closely related species, is a coral predator infamous for its outbreaks that have devastated reefs throughout much...
