3. 2. 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

4. 3. Dynamics of seashore populations of Agrostis stolonifera, Festuca rubra and Poa irrigata

   Författare :Guðrún Á. Jónsdóttir; Stockholms universitet; []
