6. Small remnant habitats : Important structures in fragmented landscapes
Sammanfattning : The world-wide intensification of agriculture has led to a decline in species richness due to land use change, isolation, and fragmentation of natural and semi-natural habitats in agricultural and forestry landscapes. As a consequence, there is a current landscape management focus on the importance of green infrastructure to mitigate biodiversity decline and preserve ecosystem functions e. LÄS MER
7. Conservation biology and genetic structure of fringe populations of the scarce heath butterfly in Sweden
Sammanfattning : During the past century, about 82% of meadows and pastures have been lost in Sweden, with negative consequences for their flora and fauna. An example is the scarce heath butterfly, which is one of the red-listed species threatened by such habitat loss through afforestation. LÄS MER

10. Quantitative genetic variation in declining plant populations
Sammanfattning : The ecological and genetic effects of habitat fragmentation are an issue of major concern in current conservation biology. Habitat fragmentation results in smaller habitat areas and as a consequence smaller and more isolated populations. Many habitats have become fragmented through human activities such as forestry and agricultural development. LÄS MER
