摘要: Caribbean coral reefs are under strong natural and human pressures many have undergone phase shifts as a result of local global change. However few studies quantified the extent these potential impacts that they on reef communities. A temporal comparative analysis several reefscape landscape metrics was conducted for data from Mahahual, Quintana Roo, Mexico, between years 2000 2006, when shift occurred. Landscape were calculated coastal cover maps obtained by multispectral satellite image classification using IKONOS imagery. These showed Mahahual lost 85 ha vegetation 43 ha over 6 years, respectively. Coastal transformation induced construction cruise ship pier multiple associated tourist developments along coast, such hotels restaurants, meanwhile alteration may be with stressors development, bleaching events hurricanes.
