We recently had a visitor, Anna, from the White Sea Biological Station staying here for two weeks. In Anna’s own words:
I have been studying polychaetes for about 20 years, starting with taxonomic studies of cryptic Orbiniid species in the White and Barents Sea. Later, I switched to polychaete anatomy and ultrastucture, and recently returned to faunistic and taxonomical investigations supported by the molecular methods.
During this visit to Bergen Museum I studied two families – the Orbiniidae and Cossuridae – from the Northern and equatorial part of the West Africa. The representatives of these families have poor morphology with paucity of useful for identification characters.
The descriptions of most of species are quite old, which means that they are too short and general, and can fit for several similar species. That’s why molecular investigations will be extremely helpful to distinguish close species here. I could recognize 15 and 3 putative species in Orbiniidae and Cossuridae respectively. After getting barcoding results I will investigate them again in Russia to make detailed redescriptions of previously known species and, most probably, descriptions of species new to science.
It will be exciting to see how many of putative species will be confirmed by barcoding!
I want to thank everybody at the Museum for their friendship and help in making my stay so pleasant. And I was absolutely fascinated by beauty and charm of Bergen – its landscapes and architecture, history and culture, and of course people.
