Protected areas (PAs) are at the forefront of conservation efforts, and yet despite considerable progress towards the global target of having 17% of the world's land area within protected areas by 2020, biodiversity continues to decline. The discrepancy between increasing PA coverage and negative biodiversity trends has resulted in renewed efforts to enhance PA effectiveness. The global conserv...

In many regions of the world, biodiversity surveys are not routinely conducted prior to activities that lead to land conversion, such as development projects. Here we use top-down methods based on global range maps and bottom-up methods based on macroecological scaling laws to illuminate the otherwise hidden biodiversity impacts of three large hydroelectric dams in the state of Sarawak in north...

Background: Biodiversity loss, due in part to intensification of agriculture, has become a global issue. In this context, fruit producers are looking for nature-friendly production methods. Their aim is to reduce intensive pesticide use and to enhance orchard management in terms of optimising habitats for beneficial organisms. However, fruit production, especially in low-stem orchards, requires...
