Ongoing studies of the polychaete worms collected by « R/V Dr Fridtjof Nansen» cruises are revealing a great diversity of species including many that are also completely new to science. This observation is demonstrated in a recently completed master thesis presented by Mr Martin M. Hektoen for the Faculty of Mathematics and Natural Sciences at University of Bergen.
Mr. Hektoen decided to to respond to our announcement in 2013 of a master project and studied the genus Diopatra in the GCLME and CCLME regions supervised by Dr. Nataliya Budaeva.
He presented his work in public before the examination commission on June 26th. The thesis is begun with an opening quote from H. Hemsworth Day (1960) reading: “ … the question as to whether there is one species of Diopatra or several species is a matter of controversy.”
Hektoen’s resolution to what may now seem more as a deceased controversy is a paper recognizing nine new species of Diopatra from the East Atlantic. The studies are based on detailed morphological studies, – microscopy and Scanning Electron Microscopy, and supplemented by DNA-sequencing of mitochondrial genes. Laborious descriptions, identification keys, and a phylogenetic analysis are some of the important elements of the thesis contents.
Adjudication of the work was performed by polychaete specialist Dr Eivind Oug from the Norwegian Institute of Water Research, Grimstad, and Prof. Anders Hobæk from the Department of Biology at UiB. We extend our congratulations to Martin for his comprehensive work and fine work, and are looking forward to see the results in a peer reviewed publication in the near future. Cheers, Martin!
