Przestrzenne i czasowe zróżnicowanie Apoidea w lasach Wielkopolskiego Parku Narodowego

Results of the investigations of spatial and temporal differentiations of Apoidea in the forests of Wielkopolski National Park were presented. It was shown that the both forest floor differ with the degree of species differentiation and domination’s structure and total number of bees. In the herbaceous layer of the forests about twice as many spedes were found than in the crowns. Also the Shannon-Weaver’s indices for bees communities of the herbs layer are higher in all three investigated forest ecosystems. The curves of Apoidea numbers in tree crowns and forest floor were similar. The curves of Apoidea numbers in the deciduous forests have one peak in the first days of May. Whereas the curves of Apoidea numbers in the pine forest have multi peak course. It was proved that trees play an important role in feeding chain of bees inhabiting deciduous forests.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę
