Occasional population outbreaks of the crown-of-thorns sea star, Acanthaster planci, are a major threat to coral reefs across the Indo-Pacific. The presumed association between the serial nature of these outbreaks and the long larval dispersal phase makes it important to estimate larval dispersal; many studies have examined the population genetic structure of A.planci for this purpose using different genetic markers. However, only a few have focused on reef-scale as well as archipelago-scale genetic structure and none has used a combination of different genetic markers with different effective population sizes. In our study, we used both mtDNA and microsatellite loci to examine A.planci population genetic structure at multiple spatial scales (from &lt;2km...

Recovery probabilities of coral reef communities after Acanthaster planci infestation: a case study at Shabror umm gam'ar, Hurghada, Red Sea, Egypt

Recovery patterns of coral reef benthic communities were estimated by linear extrapolation after Acanthaster planci outbreak of 1998 at Shabror Umm Gam'ar, Hurghada of the Egyptian Red Sea. The significance of using linear extrapolation was tested in a range of ten sites by comparison with the actual average yearly recovery rates. A total of 15 permanent transects, each is 10m long, were monitored at 10m and 12m depths in both Shabror Umm Gam’ar and the ten selected sites. The recovery rate estimated by linear extrapolation did not significantly differ from the recovery rate of stony corals in the ten selected sites. Moreover, an error of +7.69% to +17.5% increase in the extrapolated recovery rate exists and should be considered while handling the...
