Methods

Carabids were collected in forest stands in south-central Finland at the interface of the southern and middle boreal vegetation zones (Ahti et al., 1968) during 199598 and again in 2006. Pitfall traps were places in six GPS-located sampling plots in each stand, each plot containing four pitfall traps in a 4m×4m square (4 areas×4 treatments [stands]×24 traps=384 traps - only control traps were retained in BioTIME). The distance to the next nearest plot was 25 m, and at least 30m from the nearest mature-forest/clear-cut edge, except in retained patches of modified clear-cuts and gap-cut stands (Fig. 1). The traps (depth 68 mm, mouth diameter 66 mm) were partly filled with 30% propylene glycol and a few drops of detergent, and covered with 10 cm×10 cm plastic roofs, placed 25 cm above the traps to protect them from litter and rain. In 19962006, i.e., after logging operations, traps were placed at precisely the same plots as in 1995, thus randomly with respect to harrowing strips. Each year the trapping began in late May and was continuous until the end of August; the traps were emptied and serviced once a month. Carabid nomenclature follows Rassi et al. (2015). Abundance is as yearly sums.
