Description: Das Projekt "Damage of coral reefs by recreational activites - Restoration strategies and the development of novel markers for environmental stress" wird vom Umweltbundesamt gefördert und von Universität Mainz, Universitätsmedizin, Institut für Physiologische Chemie, Arbeitsgruppe Angewandte Molekularbiologie durchgeführt. Objective: The main objectives of the proposed research are: - To carry out a long term quantitative account of species diversity in 4 different localities along northern Red Sea coral reefs (Hurghada, Ras Muhammad, Nueiba, Eilat). In each place, heavily visited and less visited sites will be studied. - To establish an active restoration protocol by following the success of sexual and asexual coral recruits in situ. - To establish an ubiquitous reef-stress bioassay (HSP70) and to assess the stress loads from tourist activities in different reef localities. - To provide the scientific community and decision-making authorities with data for best assessment towards the active conservation of Red Sea coral reefs. General Information: - Description of the subject - impact of recreational activities: More and more research studies are oriented towards the impacts of recreational activities. These studies identify and evaluate the effects of runoff and sewage discharges from tourist resorts, recreational fishing and boating impacts, effects of SCUBA and skin diving, the effects of human trampling on coral reefs and sediment resuspension. These studies clearly show that recreational activities by 'innocent' visitors are usually characterized by significant damage, both directly and indirectly. - General strategy: The strategy relies on the use of stress proteins as indicators for environmental stress and on two different types of recruits (sexual and asexual) for gardening denuded reef areas, as well as on mari-culturing of propagules and adult coral subclones in 'nursery' sites in situ. - Methodology: The field investigations to study the population dynamics of hermatypic corals at 4 localities by using two techniques: (a) The use of marked line transects at fixed intervals of 1 m on flat areas and at intervals of 1 m depth on reef slopes down to 35 m depth. (b) The use of a series of photographs taken from permanently marked 1 m quadrates. Using these photographs, it will be able to follow individual colonies and estimate growth rates, mortality, species diversity, and more. In addition studies will concentrate on the subject of coral reef restoration by following the success of both coral larvae and coral fragments transplanted in different habitats within the reef (use of sexual and asexual recruits). Stress reaction of the corals will be assessed by determination of anthozoan HSP70-RNA and -protein using molecular biological and immunological techniques.
