ABSTRACT. Changes in environmental conditions impact on beetle functioning and cause variation of body part sizes. Connections between morphological variability in Trechus secalis (Paykull, 1790) adults and functional tendency of larval activity under micro-conditional transformation during natural forest recovery is revealed. The tendency of body parts to change their shape and size under annual changes of meteorological conditions impact upon the variability of beetle morphological parameters within the biotope under study.

KEY WORDS: ground beetles, cutting areas, reforestation, body size variation, dimensional parameter, population, micro-environment conditions, factor loads.
