1. Small remnant habitats : Important structures in fragmented landscapes
Abstract : 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. READ MORE

2. Linear infrastructure habitats for the conservation of plants and pollinators - The value of road verges and power-line corridors for landscape-scale diversity and connectivity
Abstract : The substantial reduction in the area of semi-natural grasslands due to the intensification of agriculture and silviculture has resulted in a dramatic decline of species that depend on these habitats. Simultaneously, the area of grassland habitats along infrastructure such as power lines and roads continues to increase and can even surpass the area of semi-natural grasslands of high nature value.

3. The Ecological Role of Roadside Stormwater Ponds - Potential to Support Biodiversity
Abstract : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. READ MORE

4. Species community structure and functional redundancy in Swedish headwater streams : local versus regional control
Abstract : Streams and rivers only contain a small proportion of the Earth's freshwater, but nevertheless harbour much biodiversity. Headwater streams are the most prevalent running water environments, but despite their wide distribution, they are often excluded from important freshwater legislation and national monitoring programmes.

5. Bird Species in Urban and Agricultural Landscapes : Bird diversity patterns along an urbanisation gradient and crop damage caused by birds on the Deccan Plateau, India
Abstract : The major human activities that have transformed the Earth include agriculture and urbanization. The present study was conducted to contribute to a description of the effect on birds of urbanization and agriculture in an Indian region. READ MORE
