  5. 24. Population dynamics of a perennial herb (Plantago maritima L.) along a distributional gradient : a demographical study

    Författare :Lenn Jerling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Populationsekologi; Grobladsväxter;

    Sammanfattning : In order to explain density distribution and provide the basis for further research on life history phenomena, the demography of Plantago maritima is described along a distributional gradient from mean water level to the epilitoral. The results seem to suggest that the factors affecting distribution are differences in 1. LÄS MER
