Opis:
Exceedingly violent winds can result in windbreak and in windthrow. It has happened in summer of 2002 in Pisz Forest District (north part of Poland). Strong wind damaged about 30 000 hectares of pine forest. In most situations, damaging wind resulted in windthrow rather than windbreak. In total 30 plots were selected for the studies, 15 plots in Pisz forest (damaged by wind) and 15 control plots in Maskulińskie District Forest (not damaged by wind). There were distinguished 5 age variants of stands, all of them in three recapitulations. The five age classes of stands were: I class (20−30 years old), II class (30−40 y.), III class (40−50 y.), IV class (50−70 y.) and V class (above 70 years old). In total 4 000 carabids individuals belonging to 46 species were caught during studies. The wards analy− sis showed substantial diference of carabid assemblages occurring in damaged and non damaged forest. In damaged forest, small zoophages, hemizoophages, an open area or eurtyopic species, xerophilus species were frequently observed. Substantial differences in mean individual biomass of assemblages occurring in damaged and non damaged forest were also observed.

Opis:
Number of carabid beetles, length of C. violaceus elytra and MIB of all carabids were studied subsequent to pitfall−trapping in 14 beech stands of increasing age (1−165 years) in Western Germany. The beech stands seemed to offer fairly constant feeding conditions for C. violaceus (and relatively small decrease in rather low level of degradation in the plantation). In total, 5,536 carabid individuals were trapped, which revealed significant increase of MIB (from 156.88 to 733.63 mg) following the logistic growth function. Due to incomplete degradation of the stands (on 'rich' soil and after using specific beech−harvesting techniques), there is a high baseline MIB at t=0 and an early onset of regenerative succession. The curve's gradient is steep and MIB reaches final value of about 650 mg in timber stands. Such high value may be explained by the good quality of loam soils in the area under study. In conclusion, logistic MIB function was calculated that describes regenerative beech succession on 'rich' soil and may help foresters to identify areas of disturbed succession.

Opis:
Investigations were carried out in 2000−2001 on the succession of carabid assemblages accompanying the spontaneous succession of pine stands on former agricultural land. Observations concerning changes in the number of carabid individuals and species, proportion of individuals in the groups: developmental, ecological, trophic, geographical, moisture preference, wing differences, as well as the mean individual biomass (MIB) indicated that the development of carabid assemblages during the spontaneous succession of stands can be compared to the regeneration process of the carabid fauna that accompany afforestation and that the direction of this development is similar to the development of carabid assemblages that accompany afforestation of farmlands.
