1. Plant species diversity patterns in a Swedish rural landscape : effects of the past and consequences for the future
Sammanfattning : Plant species richness in rural landscapes is threatened as grassland management ceases or changes, and as many remaining semi-natural grasslands are becoming increasingly fragmented. This thesis is a study of plant species diversity in a rural landscape in south-eastern Sweden, and its relationship to management history and landscape pattern. LÄS MER
2. Distribution patterns of fleshy-fruited woody plants at local and regional scales
Sammanfattning : Fleshy-fruited woody plants share a long history with humans, providing us with food and wood material. Because of this relation, we have actively moved some of these plants across landscapes and continents. LÄS MER
3. Wooded or treeless pastures? : Linking policy, farmers' decisions and biodiversity
Sammanfattning : Worldwide, biodiversity conservation is one of the key challenges for a sustainable future of nature and society. It is particularly important to preserve high quality habitats within otherwise intensively managed agricultural landscapes. LÄS MER
4. Plant community assembly in grazed grasslands
Sammanfattning : Species assembly into local communities from the surrounding region can be caused either by species failure to reach the site (i.e. seed limitation) or to establish (i.e. LÄS MER
5. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation
Sammanfattning : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. LÄS MER
