David Bruce Conn

Asif,

I have done extensive histological and ultrastructural studies on reproduction in Dreissena polymorpha and Dreissena rostriformis bugensis. I have never seen any evidence of parthenogenesis, though this would be difficult to detect in my field-collected samples using only microscopical methods. A couple of abstracts are below. A complete manuscript is in preparation.

Conference Paper Developmental and functional ultrastructure of oocytes withi...
