INWENTARYZACJA I ANALIZA FAUNISTYCZNO-EKOLOGICZNA ZGRUPOWANIA SóWKOWATYCH (LEPIDOPTERA, NOCTUIDAE) POLSKIEJ CZ??CI KARKONOSZY

摘要

The present study discusses the results of inventory research of Noctuidae community in the area of the Karkonosze National Park. Currently the appearance of 176 species was confirmed, which constitutes 35% of the Polish fauna of this family. Significantly smaller number of species was collected than it was the case in earlier research, however, taking into consideration the smaller area of exploration and smaller intensity of collecting, the results can be regarded as satisfactory. The faunistic-ecological analysis of the examined group that had been carried out, proved that the most numerous species turned out to be synantrophic moths and those, in larva stage, trophicly related to herbaceous plants (dominants). The species that were related to deciduous shrubs and trees were found in the group of subdominants. Marginal contribution (on the basis of the collected species 5.68%, on the basis of the collected specimens merely 2.43%) of montane and boreo-montane species were recorded. The above described family characteristic shows the changes which occurred in the Karkonosze natural environment. At the same time, dominant structure points to stabilized quantitative relations prevailing in Noctuidae family. It may signify that comparative stabilization has taken place in the area of the research of this family. However, it should be clearly stated that in order to confirm the observations described in the present study, conducting long-term research is required. Comparing the research carried out in different periods of time and with different intensity, brings about numerous difficulties. Therefore, it is only the development of the planned system of nature monitoring that can contribute to a better understanding of the processes that occur in natural environment and, more importantly, to distinguish between the changes taking place in the course of natural processes and those which arise as a result of human activity.
