1. Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support
Sammanfattning : Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve.

2. Integrating trees outside forests into national forest inventories
Sammanfattning : Trees Outside Forests (TOF) offer a wide range of ecological, economic, and social services. For example, they sequester carbon, provide wood for fuel and construction, protect soils from erosion, and contribute to the conservation of biological diversity. LÄS MER
3. Ecosystem Services and Disservices in an Agriculture–Forest Mosaic : A Study of Forest and Tree Management and Landscape Transformation in Southwestern Ethiopia
Sammanfattning : The intertwined challenges of food insecurity, deforestation, and biodiversity loss remain perennial challenges in Ethiopia, despite increasing policy interventions. This thesis investigates smallholding farmers’ tree- and forest-based livelihoods and management practices, in the context of national development and conservation policies, and examines how these local management practices and policies transform the agriculture–forest mosaic landscapes of southwestern Ethiopia.

4. Fungal assemblages in forest trees : influence of internal and external conditions
Sammanfattning : Forest trees host a plethora of microorganisms (bacteria, viruses, fungi) whose roles and diversity are still poorly understood despite the increased scientific interest for the past decades. The thesis focuses on the diversity of endophytic and epiphytic fungi in the aerial tissues of broadleaved trees. LÄS MER
5. Reserve selection in boreal forest : focusing on young forest biodiversity potential
Sammanfattning : Most boreal forests in North Europe are intensively managed, and the forest landscape is far from its natural stage leading to hundreds of species being threatened in Sweden alone. Reserves are established to protect biodiversity, but since the resources available for conservation do not cover all species in need of protection, effective prioritization is essential. LÄS MER
