Focus on West African crabs (Brachyura)

Shelf sampling stations

R/V Dr Fridtjof Nansen sampling stations for which benthic samples have been deposited in the Invertebrate Collections of Bergen. Red dots: the Canary Current Large Marine Ecosystem (CCLME). Yellow dots: the Guinea Current Large Marine Ecosystem (GCLME)

Since 2005 the research vessel R/V Dr Fridtjof Nansen has been sampling benthic invertebrates on the continental shelf of the large marine ecosystems (GCLME and CCLME) of West Africa. A large bulk of the material is kept in our collection and is being processed for taxonomic and other studies by several workers.

These days we are particularly focusing on the true crabs (Brachyura) and are preparing specimens for DNA barcoding with the BOLD system. This work will produce open access data (genetics, morphology, distribution) to enhance a broader knowledge about Atlantic marine biodiversity. The project is financially supported by JRS Biodiversity Foundation.

Launching PolyNor

IMG_6880Earlier this week we went to the Museum of Natural History and Archaeology in Trondheim (NTNU) to initiate the new project “Polychaete diversity in the Norwegian Sea – from coast to the deep sea” (PolyNor). The project is funded through the NBIC, and will run through 2015.
