Research in focus
Egg-sized Mauritanian bryoliths are impressive examples of a mutualistic symbiosis between a hermit crab and encrusting bryozoans. Providing a cirumrotatory growth the bryozoan colony offers the crab a helicospiral-tubular extension of its living chamber. A mandatory change of its gastropod housing as the hermit crab grows is no longer required.

PhD project
The Banc d’Arguin offshore of Mauritania is one of the most extensive warm-water heterozoan carbonate system in the present-day world. Characterized by warm-temperate to tropical water temperatures, the shelf off northern Mauritania lacks the typical warm-water carbonate facies because of increased nutrient levels. This atypical example of a carbonate depositional system that has formed under eutrophic conditions corresponds to foramol (foraminifers & molluscs) grain associations, grading to barnamol (barnacles & molluscs) and bryomol (bryozoans & molluscs) grain assemblages in the shallowest parts. A comprehensive interpretation of the sedimentary evolution and detailed distribution analyses of marine biota and their relationships provide important key-knowledge in terms of environmental and climatic reconstructions. Moreover, this natural laboratory presents a worldwide unique model of an over-fertilized environment, characterized by enormous deposition rates of carbonate secreting organism while biodiversity is extremely low. In consequence, the attributes of the Mauritanian shelf sedimentation do not simply fit into commonly used carbonate classifications and demonstrate the multi-dimensional ecological control of carbonate sedimentation. The Golfe d’Arguin thus might serve not only as modern analogue for ancient carbonate sedimentary systems but also as a model for the future, such as anthropogenic induced coastal eutrophication as a growing concern in areas with high population rates.
