1. Interactions between climate, natural disturbances, and regeneration in boreal and hemi-boreal forests
Sammanfattning : Natural disturbance is an important driving force of community dynamics in many forest types around the globe. Understanding spatial and temporal properties of disturbance events in the present and in the past is important in formulating the nature conservation strategies as well as for the modeling of climate and human impacts on forest vegetation.

2. Boreal Forest Wildfire in a Changing Climate
Sammanfattning : The boreal region contains 40% of the earth’s carbon (C) that is stored in vegetation and soils with its forests accounting for almost 30% of the terrestrial C sink. Boreal forests are experiencing some of the most rapid rates of climatic warming and increases in fire activity, threatening to release large amounts of their dense C reserves to the atmosphere.

3. Spatiotemporal streamflow variability in a boreal landscape : Importance of landscape composition for catchment hydrological functioning
Sammanfattning : The understanding of how different parts of a landscape contribute to streamflow by storing and releasing water has long been a central issue in hydrology. Knowledge about what controls streamflow dynamics across landscapes can further our understanding of how catchments store and release water, facilitate predictions for ungauged catchments, and improve the management of water quality and resources.

4. Molecular analysis of lake-sediment organic matter : long-term dynamics and environmental implications in boreal lakes
Sammanfattning : Lake sediment organic matter is material composed of residues from plants, algae, animals, fungi and bacteria. Its molecular composition is dependent on the sources as well as secondary biotic and abiotic transformations, which combined generates a highly complex matrix. LÄS MER
