A comprehensive and micro-scale land snail and isopoda data set from 16 dolines of the Aggtelek Karst Area, Hungary, as described in Kemecei et al. 2014 and Vilisics et al. 2008.

Land snails were sampled during daylight hours between 16 and 18 of August, 2007. Samples were taken from four microhabitat types: litter, trunks of live trees, dead wood (also known as coarse woody debris), and rock.

In each of the 16 dolina, seven samples were collected in the litter microhabitat along a north-south transect. In the case of the other three microhabitat types, samples were collected from three random locations per microhabitat type in each dolina. A total of 256 samples were collected, each consisting 2 sub-samples collected by 2 sampling methods: litter samples (Q) and timed search (T).

One liter of litter samples including topsoil were collected to be examined later in the laboratory. Litter samples were collected adjacent to live wood, dead wood and rocks, and not from the wood or rocks themselves. Litter samples in the litter microhabitat were not collected near wood or rocks (minimum distance of 2 meters). During 5 minutes per site of time-restricted direct search we investigated microhabitats in a 1 meter radius circle around the litter sample location, but also including tree or rock surfaces.

The vertical zone (bottom, middle or edge of the dolinas), aspect of these sample locations, along with litter depth, and litter moisture (scored on an ordinal scale: 1=dry, 2=fresh, 3=moist) were also recorded.

Individuals were categorized based on being alive or dead (empty shells with different levels of shell deterioration.

Manual samplings have taken place between

16th and 18th August, 2007. We have chosen 16 do- lines of similar traits (Table 1). During time sam- pling, two persons (F. V. and A. N.) have collected isopods for 20 minutes in each site, spending 120 minutes with sampling altogether in each doline. Time sampling provides data eligible in respect of quantitative data analyses.
