recol:data:molluscs

Communities of molluscs on spring fens of West Carpathian Mountains, Europe

Source of data

Data were partially published (e.g. Horsák & Hájek 2003).

Description of the dataset

The dataset includes information about species composition of molluscs sampled on 43 localities of spring fens in western Carpathians. At each locality, one quadrat of 16 m2 was sampled for presence of molluscs: 12 litres of soil sample was collected from the quadrat (plus plant litter and aboveground vegetation) for determination of molluscs and abundances of particular species.

Environmental variables

Several measured environmental variables were recorded for each plot, mostly chemical analysis of water sampled within the plot. For details of chemical analyses see Horsák & Hájek (2003).
