1. Phylogeny, diversity and toxin production related to cyanobacterial symbioses
Sammanfattning : Phylogeny and morphology were examined for the cyanobionts from the water fern Azolla and the cyanobacterial genus Nostoc originating from symbioses with different host plants (genera Gunnera, Cycas, Dioon, Encephalarthos, Macrozamia, and Anthoceros), the lichen genus Pannaria, and free-living Nostoc isolates from different habitats. Nostoc isolates of Pannaria formed a closely related group, but, in general, no monophyletic nature was attributed to the genus Nostoc, in contrast to the cyanobionts from Azolla which were contained in a unique monophyletic group.

2. 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
3. Effects of drought on boreal forest understory species
Sammanfattning : Extreme climatic events, such as droughts, can have large effects on biodiversity. Drought effects in forest understories are variable over small spatial scales and can be exacerbated, or buffered, by the local vegetation structure, distance to forest edges, hydrology, and soil characteristics.
