The current state of pond snail Lymnaea stagnalis \(Gastropoda, Pulmonata\) populations from water reservoirs of the Chernobyl nuclear accident zone

A comparative assessment of physiological and cygotenetical parameters in Lymnaea stagnalis populations from Perstok lake and the inlet of Pripyat river with the highest in Belarus and moderate levels of radioactive contamination have been carried out. In 2004 f γ-activity of snails from river and lake amounted to 39.2 and 567.8 Bq kg, respectively, and β-activity – to 123.4 and 7055 Bq kg resp...

Predator detection in Lymnaea stagnalis.

Laboratory-reared Lymnaea are capable of detecting and responding to the scent of a crayfish predator. The present investigation is a first attempt to characterize multiple stress-related behavioural responses resulting from predator detection and to depict the neurophysiological correlates of one of these illustrated behaviours. Snails respond to crayfish effluent (CE) by increasing the follow...

Small effective population sizes in a widespread selfing species, Lymnaea truncatula (Gastropoda: Pulmonata).

We present here a spatial and temporal population genetic survey of a common freshwater snail, also a predominantly selfing species, Lymnaea truncatula. The rate of genetic diversity loss was quantified by estimating the effective size (Ne) of the snail populations, using two different methods. A temporal survey allowed estimation of a variance effective size of the populations, and a spatial s...

Histopathology and microcystin distribution in Lymnaea stagnalis (Gastropoda) following toxic cyanobacterial or dissolved microcystin-LR exposure.

The accumulation of hepatotoxic microcystins (MCs) in gastropods has been demonstrated to be higher following grazing of toxic cyanobacteria than from MCs dissolved in ambient water. Previous studies, however, did not adequately consider MCs covalently bound to protein phosphatases, which may represent a considerably part of the MC body burden. Thus, using an immunohistochemical method, we exam...
