Reproduktionsbiologie und Phylogenie der Nemertea
Research aims are the phylogeny and evolution of Nemertea (ribbon worms); a taxon of unsegmented lophotrochozoan worms comprising approximately 1.300, mostly marine species. The focus is on the basally branching palaeonemertean groups.
Of particular interest are:
(1) comparative morphology and development of larval organs such as eyes, musculature, and nervous system,
(2) reproductive biology including comparative ultrastructure of nemertean spermatozoa,
(3) comparative morphology of the adult nervous system (P. Beckers),
and
(4) systematics and taxonomy of European species including population dynamics (C. Schmidt).
