Occurrence ofThioploca in Lake Constance and Lower Saxony, Germany
1Department of Zoology and Microbiology, Ohio University, 45701, Athens, Ohio.
Abstract:
Thioploca had been encountered in several locations in Central Europe. Five of these were revisited to find out ifT. schmidlei andT. ingrica were still present in these locations. Of the three locations in Lake Constance with abundant populations, one (Staad) contained a sparse population of small specimens ofT. ingrica only; from the others (Ermatingen and Mainau) neither species was recovered. In Lower Saxony two spots reportedly containedT. ingrica. The first of these (Bückeburg) has been destroyed by human stream improvement. The description of the other (Bad Nenndorf) was insufficient for relocation. During the search a new location containingT. ingrica was discovered, Crater Spring, across highway B65 from Bad Nenndorf.
