Abstract
Shells of Gyraulus rossmaessleri (Auerswald, 1852) infested with the bell-shaped peritrich ciliate Vorticella sp. were found in small, flooded soil depressions located in a floodplain meadow in the Upper Rhine Valley (north-eastern France). The observed prevalence was 100%. Analysis of the distribution of Vorticella aggregates on planispiral shells shows that the epibionts occur largely in the pseudo-cavities formed by the apex and umbilicus and mainly along the suture. This is the first case of ciliated epibionts on gastropods associated with temporary freshwater habitats inhabited by drought-adapted fauna. However, given the scarcity of observations of G. rossmaessleri in this region, it is difficult to affirm whether this epibiosis is relatively common.
期刊介绍:
The Journal of Conchology is the world''s oldest continuing publication on the subject. Published twice a year, it contains scientific papers and short communications on molluscs with emphasis on promoting conservation, biogeography and taxonomy. The contents cover, typically, descriptions of new species from anywhere in the world and reports concerning the ecology, distribution and status of molluscs. Both living and fossil molluscs are dealt with.
