Report for the CeDAMar grant of the taxonomist exchange programfrom Dr. Marina Malyutina , Institute of Marine Biology, FEB RAS, Vladivostok, Russia 


21st March - 19th April including the "Workshop on CeDAMar Isopoda" 


The first days I visited the Zoological Museum of the University of Hamburg. During the stay in Hamburg and Wilhelmshaven I have done the following: I started to check the isopod material from Dr. Joelle Galeron from the Nodinaut and Biozaire expeditions . The isopods of the Nodinaut cruise were compared to the isopods out of the KAPLAN material from Craig Smith.From 25th of March to 1st of April I took part in the Workshop on CeDAMar Isopoda, held at the DZMB in Wilhelmshaven, had a presentation together with Olga Golovan about the standard methods for species descriptions and started with a description of a new species of Eurycope from the ANDEEP III materialFrom 26th of March to 9th of April I stayed in the DZMB in Wilhelmshaven and worked with DIVA-2 Munnopsidae in cooperation with Dr. Nils Brenke and Dr. Wiebke Brökeland. I was identifying the munnopsid species in order to make a preliminary comparison to the richness and diversity of the DIVA munnopsids with the ANDEEP munnopsids. From the DIVA-2 isopods, 809 specimens were checked. In total, at least 42 species from 18 genera and 7 subfamilies were identified. This is less than the abundance and number of munnopsid species in the ANDEEP material ( about 6500 specimens, 208 species, 31 genera and 8 subfamilies). For future analyses of species complexes together with Dr. Wiebke Brökeland, following species were selected: Acanthocope galatheae, Betamorpha fusiformis, Syneurycope "parallele" (working name) and "Bellibos monicae" (working name).In the Zoological Institute in Hamburg (10th -19th of April) I identified the Pacific isopods from KAPLAN and Nodinaut samples on family level. Surprisingly, whether the Biozaire nore the Nodinaut and KAPLAN samples contained NOT EVEN ONE munnopsid specimen! The 72 specimens from the Nodinaut collection belong to 6 families. About 500 specimens from Biozaire were separated on 7 families. The lackMost of the specimens belong to the asellote families Desmosmatidae, followed by Haploniscidae and Macrostylidae. In comparison to Munnopsidae, all these families are slow swimmers or cannot swim. Thus, the absence of munnopsids from the sorted samples may be explained by the fact that they are fast swimmers and the sampling gear boxcorer was not capable to catch them.
