AB - Contrasting bleaching patterns in mushroom coral assemblages at Koh Tao, Gulf of Thailand Received: 21 July 2010 / Accepted: 27 August 2010 / Published online: 18 September 2010 The Author(s) 2010. This article is published with open access at Springerlink.com Extensive fields of free-living mushroom corals (Scleractinia: Fungiidae) on reef flats and upper slopes (<7 m) around Koh Tao showed massive bleaching (Fig. 1a) after rising seawater temper- atures during mid-April 2010. Using the roving diver technique (Hoeksema and Koh 2009), we examined the prevalence of bleaching in individuals belonging to 19 fungiid species encountered during 21 dives (June 25–30). At seven sites with deep slopes (18–30 m), maximum bleaching limits appeared demarcated at approximately 20 m, resulting in species commonly occurring below those depths to be little affected. At shallow depths (<20 m), a species-specific effect was observed. For example, all corals of Ctenactis echinata (Pallas, 1766), which was common on upper slopes, appeared to have remained unbleached, displaying a brown coloration (Fig. 1b). There was further fine-scale variation within species, as individuals of Fungia fungites (Linnaeus, 1758) found on the upper slopes (3–8 m) were predominantly bleached, while those on the reef flats (<3 m) had not TI - Contrasting bleaching patterns in mushroom coral assemblages at Koh Tao, Gulf of Thailand JF - Coral Reefs DO - 10.1007/s00338-010-0675-5 DA - 2010-09-18 UR - https://www.deepdyve.com/lp/springer-journals/contrasting-bleaching-patterns-in-mushroom-coral-assemblages-at-koh-bVR34eDYwW SP - 95 EP - 95 VL - 30 IS - 1 DP - DeepDyve ER -
