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. Small biotopes in agricultural landscapes: importance for vascular plants and effects of management
Abstract : As a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is not fully understood.

3. Patterns of small-scale coastal fisheries and local fisheries management in Tanzania : adaptation to a changing climate
Abstract : Coastal habitats like mangroves, seagrass meadows, coral reefs, and adjacent offshore waters constitute an important part of the tropical coastal seascape. They provide conducive environmental conditions for fish and other marine animals, which serve as food and income for coastal communities around the world. READ MORE

4. Land use effects on ecological linkages between small streams and their surrounding terrestrial habitats
Abstract : Adult aquatic insects are important vectors for aquatic transfers to terrestrial consumers and an integral component of riparian and terrestrial food webs. Incorporation of aquatic subsidies into terrestrial food webs depends heavily on the dispersal and life history traits of aquatic insects. READ MORE

5. Small biotopes: Landscape and management effects on pollinators
Abstract : The intensification of agriculture during the second half of the twentieth century, has caused sever declines of farmland biodiversity, where loss of semi-natural habitats is one of the major drivers. To halt further loss of habitat and biodiversity, agri-environmental schemes (AES) are used to compensate farmers to use methods less harmful to the environment. READ MORE
