1. Landscape Ecological Analysis and Assessment in an Urbanising Environment - forest birds as biodiversity indicators
Sammanfattning : To achieve a sustainable development, impacts onbiodiversity of urbanisation, infrastructure, land use changesand other developments must be considered on a landscape andregional scale. Landscape ecology can provide a conceptualframework for the assessment of consequences of long-termdevelopment processes like urbanisation on biodiversity on alandscape scale, and for evaluating the impacts of alternativeplanning scenarios.

2. Brazilian land use policies and the development of ecosystem services
Sammanfattning : Concerns related to global environmental changes due to land use changes have been driving international communities towards more sustainable land use systems. Brazil is a country of global strategic importance in this matter considering that it is the nation with the largest extension of preserved tropical native vegetation, recognised for its ecosystem services and high and unique biodiversity.

3. Brazilian public protection regulations and the preservation of ecosystem services and biodiversity
Sammanfattning : Brazil is significant for sustaining ecosystems services and biodiversity of global importance. However, the expansion of forestry and agriculture to supply national and international markets often results in loss of ecosystem services and biodiversity. Public protection regulations play a crucial role in setting limits for agricultural expansion. LÄS MER
4. Spatial prediction tools for biodiversity in environmental assessment
Sammanfattning : Human activities in the form of land use changes, urbanisation and infrastructure developments are major threats to biodiversity. The loss and fragmentation of natural habitats are great obstacles for the long term preservation of biodiversity and nature protection measures alone may not be sufficient to tackle the problem.

5. Ecology, Transport Infrastructure and Environmental Assessment
Sammanfattning : Transport infrastructure has a wide array of effects on ecological processes. These effects benefit certain species and might enhance or accelerate ecological processes such as colonization and dispersal, but as well extinction. LÄS MER
