2. Monte Carlo Studies of Charge Transport Below the Mobility Edge
Abstract : Charge transport below the mobility edge, where the charge carriers are hopping between localized electronic states, is the dominant charge transport mechanism in a wide range of disordered materials. This type of incoherent charge transport is fundamentally different from the coherent charge transport in ordered crystalline materials. READ MORE

3. Climate change effects on migratory birds and on the ecology and behaviour of the willow warbler (Phylloscopus trochilus)
Abstract : Recent global climate change is influencing the behaviour and ecology of species worldwide. Birds are typical systems to study in this context, as they are often migratory and thus subjected to a variety of environmental effects. READ MORE

This thesis deals with two important aspects of migration, the routes taken during migration and the birds’ behaviour at stopovers. READ MORE
