  1. 1. Carex humilis - a caespitose clonal plant: ramet demography, ring formation, and community interactions

    University dissertation from Sofie Wikberg, Plant Ecology, Ecology building, SE-223 62 Lund, Sweden

    Author : Sofie Wikberg; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ramet density; Plant ecology; Växtekologi; ramet population dynamics; aggregated ramets; intravaginal; phalanx type; LTRE; matrix model; fitness; dry grassland; hollow crown; fairy ring; central die back;

    Abstract : Carex humilis forms rings of densely aggregated ramets in dry grassland vegetation in Central Europe. In the thesis I conclude that ramet demography is important both for analyzing fitness in clonal plants and for understanding how C. humilis rings are formed. I studied the ramet demography of C.

    Abstract : About 70% of the plant species in the temperate zone are characterised by clonal growth, clonal species are also in majority in the Arctic and Subarctic where they affect the structure and composition of the vegetation. It is therefore of great importance to increase our knowledge about clonal plants and their growth and life histories. READ MORE
