Abstract

Coral reefs are widely recognized as the center of coastal biological activity, coastal protection and geological processes, and also the productive site for fisheries and tourism. By definition, ecological resilience is the ability of a system to undergo, absorb and respond to change and disturbance, while maintaining its functions and controls. The environmental conditions that favor such community resilience may be different from those that favor resistance. From six field components of reef resilience, benthic cover and coral indicators population structure are the most important for reef resilience. This research has been done at 20 sites in northern Aceh reef, i.e. Weh Island (Sabang) and Aceh Besar regency. Benthic coverage data were collected by employing line intercept transects methods, whereas data of indicator coral population structure were collected by employing belt transect. The results show that hard coral ercentage were range from 20.46% - 67.4%. Generally, hard coral cover in areas protected by the Sabang Weh Island management authority was higher than those occurred in open access areas. The resistant corals category includes Porites (massive) and Pavona which are abundant in western Weh Island, while larger coral colonies of resistant category such as Acropora dan Pocillopora, are abundant in eastern Weh Island. If sea surface temperature is increase, west and north parts of the Weh Island will be the most vulnerable areas for coral mass bleaching.

Abstract

Research about succession of macro benthos on limestone substrate was conducted atthree sites (Klah Island, Gapang Beach and Gapang Mangrove) in the coral reef ecosystem of WehIsland from April – December 2005. The selections of the sites are based on degradation of watersquality and coral reef condition. Limestone substrate as collectors were laid at 5 m waters depth ateach site, and further were taken after four and eight months. Succession pattern of macro benthoswas analyzed by Frontier Succession curve. The result shows that pattern of macro benthossuccessions were occurred significantly between locations and time. At site poor of natural coral reefcondition (Gapang Mangrove), succession pattern is in disturbance condition, while in Gapang Beachand Klah Island and Pulau Payung, which have good and fair coral condition, succession patterns aregoing in the direction of equilibrium condition. The result has indicated that waters quality is key factorfor macro benthos succession

Abstract

Mass coral bleaching is caused by high sea surface temperatures (SST). SST in theNatuna Sea have risen rapidly since late April 2010 and caused mass coral bleaching. This research wascarried out on 14 sites in Tambelan and Serasan Islands, southern Natuna Sea on November 2010. Dataof colony number and coral genera of the bleaching coral were collected using 10 x 2 m2 belt transect atreef slope, 4 – 6 meter depth below sea level. Each transect was replicated three times on each site.The research found 13 genera of bleaching coral. The bleaching coral number ranged from one to sevencolonies/transect. Acropora and Porites suffered the highest bleaching number and occurred on all sites.The highest degree of bleaching coral was occurred on the Manggirang Besar in Tambelan Islands.Over the course of data collection, bleaching in the Southern Natuna Sea was low and did not indicatethe presence of mass coral bleaching. However, the results confirm that a large number of dead coralwith algae (DCA) indicating that many corals might have been bleached approximately since July 2010.We urge the need to perform local and global actions such as promoting marine protected areas toconserve reef ecosystem especially in the southern Natuna.
