One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. READ MORE

2. How Does Intraspecific Trait Variation Influence the Climate Niche Breadth of Tropical Tree Species?
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : With the contribution of intraspecific trait variation (ITV) to ecological processes being increasingly appreciated, its role in defining niche characteristics arises as a topic of interest. I hypothesised that species with a high magnitude of ITV would occupy a larger climate niche breadth than species with little ITV. READ MORE

3. Diet variability in Eurasian perch (Perca fluviatilis) as a response to environmental variables along a latitudinal gradient
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Climate change is expected to have a profound impact on freshwater fish communities, especially at higher latitudes. In this study I investigated potential effects of climate change on the niche structure of Eurasian perch (Perca fluviatilis) by looking at their diet across a latitudinal gradient and at varying light climate.
