21. Wildfire in Swedish boreal forests - Impacts of fire severity and salvage logging on tree seedling regeneration and the belowground system
Sammanfattning : Wildfires are projected to occur more frequently and become more severe as the climate warms. The increasing release of carbon to the atmosphere from more severe fires may contribute to climate warming, and thus initiate a positive feedback loop. LÄS MER
22. Wildfire influences on stream water geochemistry in a boreal catchment
Sammanfattning : Forest wildfires are important for the structure and functioning of boreal ecosystems including biogeochemical processes. During the last decades, natural forest fires have been successfully suppressed in Fennoscandia. Therefore, our knowledge on the biogeochemical effects of forest fires is limited. LÄS MER
23. Old-Growth Forests in the High Coast Region in Sweden and Active Management in Forest Set-Asides
Sammanfattning : In today´s intensively managed landscape, very few forests with old-growth characteristics and little human impact exist. One of the rare exceptions is pine forests on rocky soils, a forest type which has probably escaped extensive human use because of its low productivity. LÄS MER
24. The Torneträsk System - A basis for predicting future subarctic ecosystems
Sammanfattning : Arctic and subarctic areas have experienced a rapid warming and substantial increases in precipitation in recent decades. The frequency and intensity of some extreme events, such as fires, winter warming events, extreme rainfall, and droughts, has also increased. LÄS MER
25. Flame-Retardant Cellulose Fibre/Fibril Based Materials via Layer-by-Layer Technique
Sammanfattning : According to an analysis conducted by the Swedish Chemicals Inspectorate in 2006, the approximate numbers of fire injuries per year in Sweden are 100 deaths, 700 major and 700 minor injuries.1 Observations also show that there has been an increase in the number of house fires during recent years.
