Abstract The natural and human effects on the last few have decayed over time. Coral reefs have been rising steadily, contributing to the degradation of coral reefs around the world. Resilience-when exposed to high temperatures and other mitigating factors, the ability of individual corals to resist bleaching, and if bleached to survive, resilience-following coral mortality, the ability of the reef population to sustain or restore structure and work and remain in an equivalent ’process’ as a result of coral mortality Coral population resilience, and particularly recovery, is strongly influenced by interactions between corals and algae that restrict coral recruitment by inhibiting settlement and the recovery potential of reefs. In this study we present the relationship between the corals, new recruitment colony, algal turfs and the herbivorous fishes and their functional community and the role of these relationships in the resilience of the coral reef particularly at Wadi El-Gemal – Hamata National park, the southern Egyptian Red Sea. The coral reefs status in the southern Egyptian Red Sea are not well studied, in particularly these regions, which now suffer from human impacts on both coral reefs and coral reef fish. In this study, we present the status and relationship of coral reefs and coral reef fish at different sites with different sheltered conditions and human impacts on the Southern Red Sea of Egypt. The study carried out in Wadi El-Gemal – Hamata Protected Area (WGHPA) in the southern Red Sea as an MPA example which expected exposed to climate changes. Wadi El-Gemal – Hamata Protected Area (WGHPA) is situated in the Red Sea Governorate approximately 50 km south of Marsa Alam. It has a total area of 7,450 km2 (land portion: 5,850 km2; sea portion: 1,600 km2, covering 305,57km2 in three NTZs). Wadi El-Gemal – Hamata Protected Area (WGHPA) encompasses a segment of the Red Sea coastal plain (about 70 km of coastline, including the ecotourism development areas) and mountains, extending roughly between 24°52’N in the north and 24°05’N in the south; and between the Red Sea shoreline in the east to about 34°28’E in the west (the Sheikh Shazli road). The study area has been divided into five sites, Three sites on-shore (sheltered) and two sites off-shore (exposed) located inside the MPA, all have either settlement, resorts or tourism activities include (snorkeling, diving, beach, bird watching, etc.) |
