11. Dispersal of bryophytes across landscapes
Sammanfattning : Dispersal, especially long-distance dispersal, is an important component in many disciplines within biology. Many species are passively dispersed by wind, not least spore-dispersed organisms.In this thesis I investigated the dispersal capacity of bryophytes by studying the colonization patterns from local scales (100 m) to landscape scales (20 km).

13. Evolutionary Processes and Hybridization within the Peat Mosses, Sphagnum
Sammanfattning : The aim of this thesis was to reveal details of the interspecific hybridization among bryophytes as exemplified by Sphagnum capillifolium and S. quinquefarium. LÄS MER
14. Plant responses after drainage and restoration in rich fens
Sammanfattning : Rich fens are an important, but threatened, habitat type in the boreal landscape. In this thesis I have examined responses of rich fen vascular plants and bryophytes after drainage and restoration.The effects of drainage on the rich fen flora were observed in a long time study and the responses were rapid and drastic.

15. Distribution Patterns and Metapopulation Dynamics of Epiphytic Mosses and Lichens
Sammanfattning : This thesis examines the relative importance of local conditions, dispersal and dynamics of the trees on epiphyte distribution patterns and colonization-extinction dynamics. Study species are the mosses Orthotrichum speciosum and O. obtusifolium, and the red-listed Neckera pennata. LÄS MER
