Evaluating Biodiversity in Fragmented Landscapes
UK forests and woodlands are often of considerable value to biodiversity. There is now a growing need to evaluate the impacts of forest management on biodiversity, in order to maintain and enhance the wildlife value at the landscape scale. The development of biodiversity evaluation tools will enable forest and land managers to make informed choices at this scale in order to provide sustainable ...
متن کاملSpecies-fragmented area relationship.
The species-area relationship (SAR) gives a quantitative description of the increasing number of species in a community with increasing area of habitat. In conservation, SARs have been used to predict the number of extinctions when the area of habitat is reduced. Such predictions are most needed for landscapes rather than for individual habitat fragments, but SAR-based predictions of extinction...
متن کاملUsing landscape history to predict biodiversity patterns in fragmented landscapes
Landscape ecology plays a vital role in understanding the impacts of land-use change on biodiversity, but it is not a predictive discipline, lacking theoretical models that quantitatively predict biodiversity patterns from first principles. Here, we draw heavily on ideas from phylogenetics to fill this gap, basing our approach on the insight that habitat fragments have a shared history. We deve...
متن کاملBiodiversity, Species Interactions and Ecological Networks in a Fragmented World
Biodiversity is organised into complex ecological networks of interacting species in local ecosystems, but our knowledge about the effects of habitat fragmentation on such systems remains limited. We consider the effects of this key driver of both local and global change on both mutualistic and antagonistic systems at different levels of biological organisation and spatiotemporal scales. There ...
متن کاملPreserving Biodiversity: Species, Ecosystems, or Landscapes?
Efforts to preserve biological diversity must focus increasingly at the ecosystem level because of the immense number of species, the majority of which are currently unknown. An ecosystem approach is also the only way to conserve processes and habitats (such as forest canopies, belowground habitats, and hyporheic zones) that, with their constituent species, are poorly known. Continued concern w...
