Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER
Sammanfattning : The abundance of predators and their impact on ecosystem dynamics is a vividly discussed topic in current ecology. In my studies, incorporating field observations, field experiments and theoretical modeling, I explored the importance of predators and predation in a low arctic tundra ecosystem in northern Norway.

8. Exploring the Dynamics of Security Community-Building in the Post-Cold War Era : Spain, Morocco and the European Union
Sammanfattning : This thesis aims to make a theoretical as well as an empirical contribution to the debate on the security community concept in International Relations (IR) by way of conducting a study of the European Union (EU) as a security community-building institution in the case of Spain and Morocco. The security community concept originally sought to define the conditions under which the threat of inter-state war would be mitigated through social transaction and expectations of peaceful change between societies and states.

9. Bloom dynamics and population genetics of marine phytoplankton - Community, species and population aspects
Sammanfattning : Phytoplankton are the most important primary producers in the world’s oceans and coastal waters, accounting for nearly half of the global net primary production. Although they are such important organisms, little is known about the ecology and dynamics of phytoplankton. LÄS MER
Sammanfattning : Bacterioplankton is characterized by high diversity, short generation times and rapid turnover. Despite their small size, these numerous microorganisms are a fundamental piece of aquatic ecosystems by channeling carbon to higher trophic levels through dissolved organic matter utilization.
