The biology of Pleurospermum austriacum (L.) Hoffm. in a relict locality of the Kashubian Lake District

Ryszard Markowski, Włodzimierz Chojnacki

Abstract


A local lowland population of the mountain species, Pleurospermum austriacum was studied. The population's spatial structure was of a cluster type. The population size, density and age-structure revealed spatial diversity and variability in time. The main reason for the instability of these traits was the changeable occurrence of generative individuals in the respective years. The reproductive tactics of the studied monocarpic perennial are characterized and its chances of survival in this locality are evaluated.

Keywords


Pleurospermum austriacum; reproduction tactics; age-structure of population
