L. Šerić Jelaska,A. Ješovnik, S. D. Jelaska,A. Pirnat, M. Kučinić, P. Durbešić: VARIATIONS OF CARABID ... Šumarski list br. 9–10, CXXXIV (2010), 475-486 elevations and lower temperatures andC. irregularisare distributed on top of the mountain with a small number of individuals on the northern plots. Geomorphologic and climatic conditions, large habitat complexity and very low disturbances in plot 1, contribute in forming more stable carabid and ant communities. Community composition can be used to indicate broader aspects of habitat quality and more general changes (i.e. degradation and recovery following stress or disturbances), (Hodkinson andJackson 2005). High abundance of carabids but low richness at the warmer plots could suggest competitive exclusion confirming that habitat stability may have unimodal effect on richness. The intermediate disturbance hypothesis predicts that diversity will be greatest when physical disturbances prevent competitively dominant species from excluding other species from the community.At the low level of disturbances, diversity is low because only the best competitors persist and competitive exclusion leads to species loss at either end of the disturbance continuum (Death andWinterbourn 1995).Stephens andWagner (2006) found that different ant functional groups were dominant under different levels of disturbance intensity. Data about species richness and habitat complexity within undisturbed forest systems with low direct anthropogenic impacts can be used as reference data for environmental monitoring of changes in temperate forests. Knowledge on how management of forests relates to forest carabids and ants diversity is poorly documented in Croatia.Wefound that ant functional groups and carabids body size analyses respond well to differences in habitat complexity.These results confirm the need for sustainable forest management that will preserve higher level of habitat complexity that provide more niches and environmental resources for exploitation and thus support dominance of larger carabids and high animal biomass. Furthermore, carabids and ants may serve as target groups in climate change risks assesment in mountain ecosystems.
