Knowledge of the biological diversity in the Norwegian Sea is limited. As a result new knowledge on distribution and abundance of benthic species are revealed as more studies are done. We have described a new species of polychaete, Scalibregma hanseni, based on newly available material. In addition a redescription of Pseudoscalibregma parvum is provided, as well as new knowledge on distribution of known scalibregmatids in the Nordic Seas. Continue reading

Benthic diversity in the deep Norwegian Sea

The diversity of benthic organisms in the Norwegian Sea is higher than previously known. Ongoing projects reveal species and new knowledge. The first expedition set to explore deep sea diversity in this area was the “Norwegian North Atlantic Expedition 1876-1878″. This expedition was one of the first exploring deep sea diversity in the world. Not until the 1980′s new expeditions aimed at studying the benthic diversity. This is continued with the ongoing MAREANO programme. Polychaete worms from these expeditions are now studied to examine deep sea diversity as such, but also differences in diversity from shelf, slope and deep sea areas. Continue reading

Norwegian nudibranchs – about the project

Norwegian nudibranchs is the title of a research project Jussi Evertsen and I have been running on and off since 1997. The main aim has been to study the diversity of nudibranchs in Norwegian waters. Number of species, their distribution and abundance was the aims from the start. After several years with this scope the project was expanded to encompass DNA barcoding of the entire Norwegian nudibranch fauna, as well as taxonomy of selected species. In the years to come taxonomy of species, species groups, and phylogeny will be the main aims of the project. Continue reading

Sampling sea slugs in the Sognefjord

Sampling nudibranchs in the outer part of the Sognefjorden at Gulen, has been a priority mid-March the last four years. This year it turned out to be very productive. More than 50 species were found providing specimens to or research on nudibranchs. This year we had the pleasure to meet Bernard Picton and work with him at Gulen. This will certainly extend our nudibranch project with collaboration with Bernard, firstly with species of the genus Flabellina. Continue reading

New nudibranchs to Norway – more knowledge on diversity of sea slugs

Five new species of sea slugs (nudibranchs) have been found in Norwegian coastal waters for the first time. Intensive field work over the last few years have provided new knowledge on distribution and abundance on several species not often observed. These results are a part of our long-going project on diversity of Norwegian nudibranchs we have had running since 1997. Continue reading
