Valvata Piscinalis - Ecology - Habitat


This small snail is found in freshwater streams, rivers, and lakes, preferring running water and tolerating water with low calcium levels.

In its native range, this species’ presence has been associated with oligotrophic nearshore zones, clear-water habitats more than turbid water, sparsely vegetated lakes or sites dominated by Chara spp. and Potamogeton spp., littoral habitats with high siltation rates, lentic and stagnant waters or slow streams, fine substrates (mud, silt and sand) – especially during hibernation, and aquatic macrophytes – for laying its egg masses.

The snail appears to be somewhat resistant to declines in macrophyte cover, because populations have been recorded to survive in ponds after vegetation cover almost completely disappeared. This species is found at depths anywhere from 0.5 m to 23 m in the Great Lakes. In Europe, it usually is found in depths of up to 10 m.

Valvata piscinalis tolerates varying calcium concentrations, and generally does not require very high temperatures to survive. Individuals can overwinter in mud, often experiencing growth during this cold period, although some populations may experience mortality in frozen littoral zones. This species can tolerate salinities up to 0.2% and is distributed in northern parts of the Curonian Lagoon, where it experiences periodic intrusions of saline water for a few hours or days at a time.

Famous quotes containing the word habitat:

    Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home.
    John Dewey (1859–1952)

    Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.
    William James (1842–1910)
