1. 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

2. Spatial distribution and conservation planning of seabed biological diversity
Abstract : Knowledge of spatial patterns of biota has become a commodity for conservation practitioners and spatial ecologists alike. This type of information enables the identification of representative and unique biological features (at some nominal scale) which itself constitutes the application par excellence of knowledge of biodiversity distribution as it relates to the design of reserve networks and the realization of spatial planning.

3. 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.

4. Silviculture adapted to multiple goals in Swedish small scale forestry : methods for choosing practices, biotopes, stands and events
Abstract : During recent decades a new type of private forest owner has appeared in Sweden, with forestry goals other than simply generating money from wood production; these goals include hunting, maintaining biodiversity, cultural aspects and historical values. However, multiple goals often conflict with each other, leading to a problem of finding practices that can deliver several goals at the same time. READ MORE

5. Linking biodiversity and recreational merits of urban green spaces : methodological development
Abstract : Urban green spaces play an important role in promoting both biodiversity and human recreation. This thesis therefore attempted to link biodiversity and recreational values of urban green spaces through an interdisciplinary research of trade-offs and synergies between biodiversity conservation and human recreation.
