Prof. Gordan S. Karaman, an outstanding and well-known expert on amphipods, as well as the journal Contributions to Zoology (former Bijdragen tot de Dierkunde) kindly permitted me to use a beautiful drawing of Gammarus lacustris as logo for my homepage. It is derived from Karaman and Pinkster’s 1977 publication on the Gammarus pulex-group [Fig. 12A from Bijdragen tot de Dierkunde 47 (2)]. I would hereby thank him and the journal very much for this honor and permission.
