Abstract/Contents: | "It is suggested that spatial niche-separation between grassland species occurs in the regeneration phase and that the differential response of species to micro-variation in leaf cover may allow coexistence at high density. A technique for measuring heterogeneity in leaf-cover on a scale of 1-cm2 units (micro-cover) and the demography of seedling cohorts of Reseda lutea and Anthyllis vulneraria in relation to this heterogeneity is described. Densities of seedlings were significantly higher in micro-sites of low micro-cover for R. lutea and for one of the three cohorts of A. vulneraria studied. No relationship was found between mortality and density of seedlings or micro-cover. The ultimate causes of these distribution patterns of seedlings and their consequences for the maintenance of species diversity in grassland are discussed." |
