1. Population processes in heterogeneous landscapes
Sammanfattning : Population processes in heterogeneous landscapes are notoriously difficult to study, both empirically and theoretically. There are well-documented effects of scale (both total size and resolution of the system), density dependence, temporal and spatial variation, as well as effects of habitat-shape, -boundary and -edge.

2. Living in a Variable Environment : Reproductive Decisions in Wild Bird Populations
Sammanfattning : In nature, environments are often variable and heterogeneous influencing ecological and evolutionary processes. This thesis focus on how animals interact with their environment and how that affects the reproductive decisions they make. LÄS MER
3. Multiscale models and simulations for diffusion and interaction in heterogeneous domains
Sammanfattning : We investigate multiscale and multiphysics models for evolution systems in heterogeneous domains, with a focus on multiscale diffusions. Although diffusion is often studied in terms of continuum observables, it is a consequence of the motion of individual particles. LÄS MER
4. Diversity, dynamics and deficits : the role of social networks for the health of aging populations in Indonesia
Sammanfattning : Background: This thesis takes as a predicate that humans are social animals and as such, that their social networks and health are intrinsically connected. A guiding heuristic of this thesis was the Berkman model which conceptualizes how social networks impact health. LÄS MER
5. Evolution and learning in games
Sammanfattning : This thesis contains four essays that analyze the behaviors that evolve when populations of boundedly rational individuals interact strategically for a long period of time. Individuals are boundedly rational in the sense that their strategy choices are determined by simple rules of adaptation -- learning rules. LÄS MER
