摘要
在莱茵河上游河谷(法国东北部)的洪泛区草甸上的小型水淹土壤洼地中,发现了被钟形富缘毛纤毛虫 Vorticella sp.侵染的 Gyraulus rossmaessleri(Auerswald,1852 年)贝壳。观察到的感染率为 100%。对平面螺旋贝壳上的涡虫聚合体分布进行的分析表明,附生体主要出现在顶端和脐部形成的假腔中,并且主要沿着缝合线分布。这是第一例与适应干旱的动物栖息的临时淡水生境有关的腹足类动物身上的纤毛附生虫。然而,由于在该地区很少观察到 G. rossmaessleri,因此很难确定这种附生虫是否比较常见。
Love story or fling? The first observation of Vorticella sp. (Ciliophora: Peritrichia) on the freshwater snail Gyraulus rossmaessleri (Auerswald, 1852)
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.
