2. Responses of boreal forest understory plant communities to climate and forestry
Abstract : A warming climate is altering species distributions and community compositions. To understand and predict changes in species distributions to climate change, we often use species occurrences together with large-scale regional climate data. This can be problematic for several reasons. READ MORE

3. Land Use Change in Space and Time : implications for plant species conservation in semi-natural grasslands
Abstract : Land use change has during the last century altered the traditional rural landscape in Sweden, resulting in a major decline in species diversity. Traditional small-scale farming, with a remarkably high small-scale species richness, has changed in favour of rationalized agriculture, and many semi-natural grasslands, i.e. READ MORE

5. Exploring connections in social-ecological systems : The links between biodiversity, ecosystem services, and human well-being in South Africa
Abstract : A key challenge of the Anthropocene is to advance human development without undermining critical ecosystem services. Central to this challenge is a better understanding of the interactions and feedbacks between biodiversity, ecosystem services and human well-being, which interact in dynamic and complex social-ecological systems.
