The presentation of contemporary changes accounts for different trends: (a) population decline or disappearance of some species (shrinking ranges), (b) population increases or expansion of other species. The fauna is described dynamically against the background of environmental change (fluctuation hypothesis). It is postulated that updated comprehensive studies of faunal resources need to be undertaken, concentrating on species diversity and density.}, type={Text}, title={Pollinating insects (Hymenoptera: Apoidea, Apiformes) as an example of changes in fauna}, URL={http://rcin.org.pl/Content/42040/PDF/WA058_53183_P256-T52_Frag-Faun-Nr-2.pdf}, volume={52}, number={2}, journal={Fragmenta Faunistica}, publisher={Museum and Institute of Zoology, PAS}, keywords={bees, Apoidea, wild bees, bumble bees, honey bees, Apiformes, changes in fauna, species extinction, species expansion, permanence of fauna, Białowieża Primeval Forest, pollinators, pollinating insects, Poland, Europe, Hymenoptera, hymenopterans, Insecta, insects, populations, ecology}, }
