Plant strategies along the elevation gradient: the case of Campanula populations on Mt Olympos

Abstract

We studied all Campanula species occurring on Mt Olympos, a total of nine species. Their distribution on the mountain, along the altitudinal gradient permitted the testing of hypotheses concerning the change of plant characteristics with elevation. These characteristics included plant and flower morphology, biomass allocation, flower phenology, pollination and reproduction. Studying these characters we can sketch the life history strategies of the species and comprehend the way with which the formation of these strategies is affected by their habitat. Additionally, we estimated the size, density and spatial patterns of Campanula populations in order to assess not only changes of the population parameters in space or time, but also their effect on the plant characters under study. For each species, altitudinally different populations were chosen. Field data were collected from 1992 to 1995. We searched for altitudinal patterns mainly at the genus level. This is the first such an approac ...
