Forested scree slopes represent one of the types of shallow subterranean habitats characterised by several unique traits, such as close contact with the soil surface, better availability of organic matter, and lower seasonal fluctuations in microclimate. Relatively varied assemblages of gastropods were collected using a series of subterranean traps filled with formaldehyde or ethylene glycol, exposed inside a forested scree slope at depths from 5 to 95 cm in the Natural Nature Reserve Sivec (eastern Slovakia). The number of gastropods was smaller compared to arthropods. The material of 120 specimens consisted of 22 gastropod species representing 15 families. Almost 87% of the specimens were captured near the soil surface (5– 15 cm) and only few of them penetrated deeper. Ethylene glycol was more effective than formaldehyde in collecting gastropods. No subterranean species were found. Forest species predominated over some hygrophilous and petrophilous ones.

The thermal regime of a phonolite scree slope on Klíč Mt., North Bohemia, Czech Republic, was monitored by miniature data loggers. The spiders were collected throughout the entire scree field area and on the adjacent cliff. In 2005 and 2006, the mean internal temperatures at the lower margins of the scree slope were 0.1 and 0.5°C, whereas the mean external ambient temperatures were 6.8 and 7.2°C, respectively. The difference, therefore, is 6.7°C. The long-term cooling of the basal portions, along with the winter heating of the central and upper parts of the scree, are the most specific microclimatic phenomena. The boreomontane species inhabit the extremely cold vents at the lower margins of the scree slope. Species of alpine origin inhabit the middle portions of the scree slope. Six thermophilous species inhabit the sun-exposed rock margins of Klíč Mt., which is nearly at the uppermost limit of their vertical distribution in the Czech Republic.
