1. Species interactions govern evolutionary and ecological effects of population harvesting
Sammanfattning : Harvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment.

2. Asymmetries : Conceptualizing Environmental Inequalities as Ecological Debt and Ecologically Unequal Exchange
Sammanfattning : In this compilation thesis, consisting of six papers and an introductory chapter, the concepts of ecological debt, climate debt, ecologically unequal exchange, and unequal carbon sink appropriation are at the centre. Their intellectual and political histories are traced to environmental justice movements, ecological economics and neo-Marxist economics. LÄS MER
3. On The Big Challenges of a Small Shrub : Ecological Genetics of Salix herbacea L
Sammanfattning : The response of plants to climate change is among the main questions in ecology and evolution. Faced with changing conditions, populations may respond by adapting, going extinct or migrating. Fine-scale environmental variation offers a unique mosaic to explore these alternatives. LÄS MER
4. Management Practices for Dealing with Uncertainty and Change : Social-Ecological Systems in Tanzania and Madagascar
Sammanfattning : The development of human societies rests on functioning ecosystems. This thesis builds on integrated theories of linked social-ecological systems and complex adaptive systems to increase the understanding of how to strengthen the capacity of ecosystems to generate services that sustain human well-being.

5. Sexual Selection and Adaptation to Novel Environments
Sammanfattning : The work included in this thesis aims at exploring the environmental sensitivity of benefits and costs of sexual selection through a combined empirical and theoretical effort, to increase our understanding of the impact of environmental change on sexually reproducing populations.Can sexual selection promote adaptation to novel environments? Sexual selection for good genes should accelerate adaptation by granting higher reproductive success to individuals of high genetic quality. LÄS MER
