21. Contested Landscapes : social-ecological interactions between forestry and reindeer husbandry
Sammanfattning : Throughout northern Fennoscandia, reindeer husbandry is a central part in the cultural heritage of the Sámi people. In its history, Sámi culture and reindeer husbandry have undergone significant adaptations to environmental, social and political challenges. LÄS MER
22. Ecology and conservation of bryophytes and lichens on Fagus sylvatica
Sammanfattning : .... LÄS MER
23. Disentangling Lecania
Sammanfattning : This thesis focuses on phylogenetic, taxonomic, ecological, and conservation aspects of the crustose lichen genus Lecania (Ramalinaceae, lichenized Ascomycota). Lecania has previously been defined on basis of relatively few morphological characters, and the genus had never been treated in molecular phylogenies. LÄS MER
24. 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
25. Insights into the ecology and genetics of lichens with a cyanobacterial photobiont
Sammanfattning : Nature conservation requires an in-depth understanding of the ecological processes that influence species persistence in the different phases of a species life. In lichens, these phases comprise dispersal, establishment, and growth. LÄS MER
