abstract:
In the years 2004-2005 chrysomelid beetles were collected at 7 stations marked out in plant communities of higher humidity (transitional and low bogs, alder swamps, moist meadows and rushes) in the Kozłowiecki Landscape Park area. The chrysomelids occurred most numerously in rush communities (33) and less numerously in transitional/low bogs, moist meadows (23 and 20, respectively) and alder swamps (15). The chrysomelid communities were dominated by hydro-, higro-, and mesohigrophilous species, which are bio-indicators of the preservation degree of these habitats. The highest share of those species was found in rushes (66.67%), lower transitional/low bogs and alder swamps (47.83 and 46.67%, respectively), and the lowest moist meadows (40%). They also reached high values on the fidelity index with relation to a definite kind of plant community. Wet biotopes of the park are also the refuge for boreal species like: Chrysomela cuprea (collected in 2005), Hydrothassa marginella, Galerucella grisescens and Phyllotreta flexuosa. The occurrence of those stenotopic species emphasized the high preservation degree of wet biotopes of the Kozłowiecki Landscape Park, and consequently confirmed the presence of favourable conditions for their development in the investigated area.
