11. Adaptation and Constraint in the Plant Reproductive Phase
Sammanfattning : Conservatism is a central theme of organismic evolution. Related species share characteristics due to their common ancestry. Some concern have been raised among evolutionary biologists, whether such conservatism is an expression of natural selection or of a constrained ability to adapt. LÄS MER
12. The use of molecular markers for identifying species diversity and functional variation of ectomycorrhizal fungi
Sammanfattning : Ectomycorrhiza (EM) is a symbiosis between soil living fungi and the roots of woody plants. EM fungal communities are important in forest nutrient cycling, they are species rich and their structures vary between habitats and over time. LÄS MER
13. Nature, culture, rights : exploring space for indigenous agency in protected area discourses
Sammanfattning : There is considerable geographical overlap between areas set aside for nature conservation or protection and Indigenous peoples’ lands, and the social, economic, and political consequences of protected areas have often been extensive for Indigenous peoples. Discourses of conservation converge with discourses of Indigenous peoples, and both carry a legacy of colonial constructs and relationships. LÄS MER
14. Effects of Vibrio cholerae protease and pigment production on environmental survival and host interaction
Sammanfattning : Only two out of more than 200 V. cholerae serogroups, classified on the basis of LPS structure, are associated with epidemic or pandemic cholera. These toxigenic serogroups carry phage-derived pathogenicity islands coding for the main virulence factors for establishment of cholera disease – cholera toxin (CTX) and toxin-coregulated pilus (TCP).

15. Extending dynamic vegetation models to simulate range shifts
Sammanfattning : In response to rapid climate change and increasing human pressure, a wide variety of taxa have shifted their distribution in the past decades (range shift), with important consequences for ecosystem services and human health and economy. However, it is not yet clear whether most species will be able to track their favourable habitats or lag behind the climate signal (migration lag). LÄS MER
