The thermal tolerance of crown-of-thorns (Acanthaster planci) embryos and bipinnaria larvae: implications for spatial and temporal variation in adult populations

To understand the role of sea temperature on the population biology of the crown-of-thorns sea star Acanthaster planci, the thermal window for embryonic and larval development was investigated. In two experiments, the response of embryos and larvae across 12 temperatures from 19.4 to 36.5 °C was quantified as the percentage of individuals reaching cleavage stage embryos, blastula...

Closing the circle: is it feasible to rehabilitate reefs with sexually propagated corals?

Sexual propagation of corals specifically for reef rehabilitation remains largely experimental. In this study, we refined low technology culture and transplantation approaches and assessed the role of colony size and age, at time of transfer from nursery to reef, on subsequent survival. Larvae from Acropora millepora were reared from gametes and settled on engineered substrates...

The corallivorous flatworm Amakusaplana acroporae: an invasive species threat to coral reefs?

Fatal infestations of land-based Acropora cultures with so-called Acropora-eating flatworms (AEFWs) are a global phenomenon. We evaluate the hypothesis that AEFWs represent a risk to coral reefs by studying the biology and the invasive potential of an AEFW strain from the UK. Molecular analyses identified this strain as Amakusaplana acroporae, a new species described from two US...

Vast reef-like accumulation of the hydrocoral Errina antarctica (Cnidaria, Hydrozoa) wiped out in Central Patagonia

The hydrocoral Errina antarctica is described around southern South America (south of 50°S; Fig. 1) and along the Scotia Arc down to 771 m (Cairns 1983). In Chile, we found E. antarctica in diving depths as far north as 43°25′S. It has been identified as key structural species creating important habitats for a multitude of organisms (Häussermann and Försterra 2007; Fig. 1b, d...

Spawning in Trochus maculatus: field observations from Bolinao, Pangasinan (Philippines)

The maculated top shell Trochus maculatus inhabits the lower to sublittoral zones in Indo- and South Pacific reefs, feeding on green and red algae and benthic diatoms. As T. maculatus is economically important, e.g., its meat for food and its shell potentially in button making, Thailand has developed culture methods for this species (Chunhabundit et al. 2001). Hatchery rearing of...

Calcification rates of the massive coral Siderastrea siderea and crustose coralline algae along the Florida Keys (USA) outer-reef tract

Coral reefs are degrading on a global scale, and rates of reef-organism calcification are predicted to decline due to ocean warming and acidification. Systematic measurements of calcification over space and time are necessary to detect change resulting from environmental stressors. We established a network of calcification monitoring stations at four managed reefs along the outer...
