A kelési diszperzió vizsgálata a magyarországi parlagisas-populációban

Abstract

The Eastern Imperial Eagle (Aquila heliaca) is a globally threatened raptor species, being distributed from the Carpathian basin to the Baikal Lake. The world’s total breeding population of the species is about 3000-7000 pairs in Europe and Asia, the size of the Hungarian population is roughly estimated at 140-150 pairs. After a recent bottleneck and habitat loss, population census in Hungary began to grow, along with an expansion in the breeding area. This expansion showed an interesting pattern that might be analyzed via individual-based analyses.
