1. Constructing a food web from inventory data in a boreal forest-dominated national park in south-eastern Sweden
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : A food web was constructed for a boreal-forest dominated national park in south-eastern Sweden, called Tyresta national park and its surrounding nature reserve. Due to increasing threats to mammalian species and their critical role in the food web mammals were used as the outset of the food web, and from there branching out to taxa trophically interacting with mammals directly and indirectly.

2. Restoration effects on benthic macroinvertebrate diversity and community composition in a river
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Physical restoration efforts are common methods to restore running waters containingdegraded ecosystems due to anthropogenic activities such as irrigation, ditching, dammingand flood prevention. The goal is usually to restore waters to a more natural state, creatingmore physically complex habitats supporting a larger number of species of both fish andinvertebrates, hence increasing biodiversity.

3. Associations between body size polymorphism in Arctic charr and benthic invertebrate communities – clues to mechanisms for population differentiation?
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Many fish populations in the north have divided into coexisting ecotypes that differ in body size. While such polymorphic fish populations have been studied for many years, the understanding of how different types of selection contribute to the formation of dwarf- and giant ecotypes remains limited.

4. Acquired and lost structure-functions of non-enveloped and enveloped viruses
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Viruses are biological entities that constantly affect the world around us and in many cases they can harm the health of humans and negatively impact food production, in agriculture andfisheries. The project concept is that, through the structural studies of viruses that infectsimple hosts, it is possible to point out structural features that are unique and conserved inviruses, that infect human, other animals, and crops, in the same phylogenetic lineage.

5. Tree origin or traits? : what makes a tree suitable as an urban habitat for insect fauna?
University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Abstract : A global decline in diversity of plants and animals, has led to an increased focus on the topic of biodiversity. The trend of urbanisation can be a facilitator for biodiversity loss, and cities generally have lower densities of species compared to non-urban areas. This has made biodiversity in cities an important concept. READ MORE
