Popis: A Berlese–Tullgren funnel is described which features a 600-w heating element, a tray having a single bottom of new design, and ventilating screens below the tray to prevent condensation of moisture on the inner wall of the funnel. The funnel efficiently extracts grassland arthropods from coarse plant matter. Also described is a salt-water flotation separator, which extracts any arthropods from the fine litter and soil that may pass through the funnel screens.
