1. Secondary succession in tropical dry forests : drivers and mechanisms of forest regeneration
Sammanfattning : Secondary succession is a complex process involving numerous factors acting across scales. Understanding secondary succession in tropical dry forests is important for the conservation and restoration of this highly threatened biome. LÄS MER
2. Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees
Sammanfattning : Tropical climate is getting warmer, with more pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, such as photosynthesis and leaf respiration, to these new conditions.

3. 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.

4. The impact of forest on pest damage, pollinators and pollination services in an Ethiopian agricultural landscape
Sammanfattning : The distribution of wild biodiversity in agroecosystems affect crop performance and yield in various ways. In this thesis I have studied the impact of wild biodiversity, in terms of trees and forest structures, on crop pests, pollinators and the pollination services provided in a heterogeneous landscape in southwestern Ethiopia.

5. Aerosol Exchange between Forests and the Atmosphere : Fluxes over a Tropical and a Boreal Forest
Sammanfattning : The main goal of this thesis was to investigate primary biogenic aerosol emission from the Amazon rain forest through measurements of vertical turbulent aerosol number fluxes. In addition, the particle dry deposition sink has been analysed and quantified, and is also compared with the dry deposition sink at a boreal forest site. LÄS MER
