B1.14 | TROPICAL MARINE ECOSYSTEMS: DIVERSITY AND DYNAMICS OF CORAL REEF ECOSYSTEMS AND REEF-ASSOCIATED FISH ASSEMBLAGES (2008-2011)

Tropical marine systems, particularly coral reefs, provide a wealth of ecosystem services. However, many reefs are already severely impacted by the effects of climate change. Large-scale coral bleaching followed by coral die-off due to elevated sea surface temperatures has been observed repeatedly since 1996, particularly in the seas surrounding the Arabian Peninsula. The Socotra Archipelago, situated east of the Horn of Africa, is renowned as a biodiversity hot spot. Along with several other observation sites in the region, it has been selected as a prime site for studying biodiversity dynamics and tropical marine ecosystem shifts in response to climate change. The project pursues the following objectives:

• To investigate the biodiversity and ecosystem dynamics of tropical marine ecosystems and communities, and to study the range shifts of selected populations under current and predicted future climate scenarios;

• to establish coupled niche and range shift models predicting the dynamics of selected biota, biotopes and eco-geographic units, and to validate and iteratively improve these models through comparison with empirical and historic data (see A.3 and A.4);

• to use GIS-based remote sensing techniques as an innovative ex-situ method for mapping the diversity and distribution of coastal, and particularly reef fish assemblages (to be subsequently extended to other benthic organisms);

• to generate added value by utilising the scientific results for socio-ecological and socio-economic development.

We use existing data sets (i.e. fish inventories, biotope maps generated by remote sensing, and time-series data  from long-term monitoring programmes) as a reference against which to compare observed current and predicted future shifts. Our work forms part of the overarching project “Tropical Marine Systems”, thereby complementing activities carried out in other project areas (i.e. A.3, A.4, F.5).
