Island geography and ecology of distinct terrestrial islands
The Quartz Islands project is a joint research project of Prof. Dr. Severin Irl (University of Frankfurt) and Dr. Ute Schmiedel and Dr. Jens Oldeland (both Universität Hamburg).
In this study, we use a combined approach of Remote sensing techniques, Community ecology and Island Biogeography to quantify drivers of different aspects of taxonomic and functional richness as well as endemism in a unique system of edaphic habitat islands. We identify habitat island structure, heterogeneity and diversity as well as environmental and geographic isolation based on satellite image classification and a subsequent ground truth vegetation survey. We quantify the processes and drivers at different scales (community, island, landscape) and on different levels of organization (species and functional).
Our study area is located in the South African Succulent Karoo, a biodiversity hotspot with outstanding numbers of vascular plant species. Our archipelago-like study system of quartz fields contains high numbers of succulent dwarf shrub species, of which many are local endemics and highly adapted to a small scaled mosaic of habitats within the quartz fields.
