Effects of sedimentation rate to coral reef in the cristo rei Sub-district waters of the Dili District of timor-leste

Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1

Abstract

The existence of sediments at area coral reef has a negative effect. The sedimentation rate suspended would inhibit the process of zooxanthellae photosynthesis and deposited be due smothering for coral polyp. This aim to calculate of sedimentation rate on coral reefs, and analyze the relationship and effects of the sedimentation rate to coral reefs. Observations of coral cover using of intercept transect line method, and measuring the sedimentation rate is used of the sediment traps. Data analysis will be statistically analyzed by ANOVA of F test (P<0.05), PCA and regression analysis (R2). Percentage of live coral cover at five stations between 14.75 to 77.25%. The sedimentation rate values between 3.30 to 13.60 mg/cm2/day. The level of the effect sedimentation rate of percentage of coral covering was 65.40% and mortality index coral reefs were 53.60%. The level of coral mortality risk of 0.06 to 0.72%. The sedimentation rate is very negative effect on the live coral and mortality index. If it not had an effect of the sedimentation rate, the live coral cover of 91.78% and if any increased of sedimentation rate will cause Mortality Index is 0.079%.
