The aim of the study was to determine the effect of soil temperature and moisture on the feeding activity of soil fauna. To measure this activity, we conducted two short-term (14 days) experiments using the bait-lamina method. In experiment 1, the enchytraeid Cognettia sphagnetorum was added to defaunated mor humus. The experiment included incubations at four temperatures (−4, 5, 14, and 24°C) and three moisture regimes (220, 260, and 300% of dry weight). No feeding activity was detected at −4°C, but at other temperatures the bait-laminae were perforated, and the number of baits consumed increased with time. Because of variable animal survival and because of the rather low bait consumption, the effect of temperature and moisture on the feeding activity was unclear. In experiment 2, intact soil cores were either pre-treated at −21°C or were not treated until being placed at −4, 5, 14 and 24°C and two …
