Different age and spatial structure of two spontaneous subpopulations of Taxus baccata as a result of various intensity of colonization process

Obviously, the distribution of individuals of the ornithochoric species T. baccata is strongly determined by the availability of mother trees in a distance suitable to be bridged by birds. Long distances limit seed supply heavily and retard and prolong the period of colonization. As a consequence, dispersal distances influence strongly age and spatial structure of cohorts founded from isolated (groups of) mother trees.
