Bleaching of corals on the Great Barrier Reef: differential susceptibilities among taxa

Conditions of coral communities in the Gulf of Thailand: a decade after the 1998 severe bleaching event

“…The presence of low live coral coverage and juvenile coral density in con trast with a high density of D. setosum at Koh Khang Khao may partly explain why there are no structural reefs on the coasts of many islands in the inner part of the Gulf of Thailand (Tsuchiya et al 1986; Menasveta 1986). Also there are significant differences in the bleaching response between coral taxa (Marshall and Baird 2000). Only a few colonies of Acropora, which is highly susceptable to coral bleaching, were recorded in this study, but the less susceptable taxa, like Porites, con tinue to be both dominant components and successful recruiters in coral communities in the Gulf of Thailand.…”

Palau’s coral reefs show differential habitat recovery following the 1998-bleaching event

“…Loya et al (2001) showed that some species are tolerant to thermal stresses and were classified as 'winners', while others were not so tolerant, and were called the 'losers'. Many other reports have highlighted the extent of damage caused by the 1998-bleaching event, suggesting that differential survival varied in accordance with species type (Marshall and Baird 2000), colony size (Bena andvan Woesik 2004), depth (van Woesik et al 2004), flow rates (Nakamura and van Woesik 2001) and geographic location (van Woesik 2001;Sheppard 2003).…”

“…Coral bleaching events in recent years have been a consequence of high sea surface temperatures in direct combination with high irradiance (Glynn 1993(Glynn , 1996Shick et al 1996;Hoegh-Guldberg 1999;Marshall and Baird 2000). Bruno et al (2001) reported wide-scale coral bleaching and high mortality on the reefs of Palau in 1998 (Fig.…”

High-precision 238U–234U–230Th disequilibrium dating of the recent past: a review

“…Six weeks after the onset of El Niñ o in 1998, for example, up to 83% of colonies studied on the Great Barrier Reef were affected by bleaching (Marshall and Baird, 2000). The 1997-1998 global bleaching event effectively destroyed 16% of the world's coral reefs with 32% more under threat (Wilkinson, 2002, pp.…”
