1. Effects of fine woody debris on juvenile brown trout (Salmo trutta) and drifting invertebrates
Sammanfattning : In boreal forest streams, woody debris is an important habitat component. Stream invertebrates and salmonids such as brown trout benefit from in-stream wood. LÄS MER
2. Forest – stream linkages : Brown trout (Salmo trutta) responses to woody debris, terrestrial invertebrates and light
Sammanfattning : Forests surrounding streams affect aquatic communities in numerous ways, contributing to energy fluxes between terrestrial and lotic ecosystems. The five papers in this thesis focus on woody debris, terrestrial invertebrates and light, three factors influenced by riparian zone structure, potentially affecting streams and brown trout (Salmo trutta).

3. The importance of small forest set-asides for saproxylic biodiversity at stand- landscape- and regional scales
Sammanfattning : .... LÄS MER
4. Habitat compensation in nature-like fishways : Effects on benthos and fish
Sammanfattning : The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams and rivers affected by hydroelectric development. These fishways also have the potential to function as habitat compensation measures when running waters have been degraded or lost. LÄS MER
5. 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
