Feeding Preferences of Acanthaster planci (Echinodermata: Asteroidea) under Controlled Conditions of Food Availability
Feeding preferences of the crown-of-thorns sea star, Acanthaster planci (L.), were studied in a series of laboratory-based feeding trials wherein sea stars were provided with equal availability of six different coral species. The order in which corals were consumed was then used to ascertain feeding preferences. Crown-of-thorns sea stars exhibited strong and consistent feeding preferences acros...
متن کاملInteractions between Acanthaster planci (Echinodermata, Asteroidea) and Scleractinian Corals at Kona, Hawai'i
Annual assessments of reef communities at Kona, Hawai'i, from 1985 to 1995 determined that the corallivorous sea star Acanthaster planci preferred as prey the smaller colonies of Pocillopora meandrina over the far more abundant Porites compressa and P. lobata. This finding came from three distinct settings: a Reef-Top habitat, where large (> 15 em) colonies of Pocillopora meandrina were dominan...
متن کاملEffect of stony corals extracts on feeding by Acanthaster planci
The preference of the starfish Acanthasterplanci (Linnaeus, 1758) for 3 species of corals which survive A. planci outbreaks (Diploastrea heliopora, Porites rus, and Coscinaraea colurnna), and the effects of organic and aqueous extracts of these corals on A. planci feeding, were investigated experimentally in the laboratory. We hypothesized that extracts of these corals deter feeding by A. planc...
متن کاملFeeding Preferences of the Cushion Star Culcita Novaeguineae in the Presence of the Crown of Thorns Starfish Acanthaster Planci
Crown of thorns starfish (Acanthaster planci Linné 1758) are notorious coral reef devastators; they decimate coral populations, thus changing the coral reef habitat and killing many organisms that depend on the coral. Culcita novaeguineae (Muller and Troschel 1842), or cushion stars, are corallivores and generalists that live in Pacific reefs. Because C. novaeguineae and A. planci have similar ...
متن کاملMolecular phylogeny of the Valvatacea (Asteroidea: Echinodermata)
The Valvatacea is one the most ecologically important, taxonomically diverse, and widespread groups of postPalaeozoic (i.e. modern) Asteroidea. Classification within the group has been historically problematic. We present a comprehensively sampled, three-gene (12S, 16S, early-stage histone H3) molecular phylogenetic analysis of the Valvatacea. We include five of the six families within the Paxi...
