2. 1. A land of one's own : Sami resource use in Sweden's boreal landscape under autonomous governance

   Author : Gudrun Norstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : HUMANIORA; HUMANITIES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; HUMANIORA; HUMANITIES; ALS; archaeology; boreal forest; dendrochronology; forest history; historical maps; interdisciplinary research; lidar; Sami; settlement patterns; ALS; arkeologi; boreal skog; bosättningsmönster; dendrokronologi; historiska kartor; lidar; samer; skogshistoria; tvärvetenskap;

   Abstract : The Sami dominated large parts of boreal Sweden well into the 18th century, and knowledge of Sami subsistence patterns is therefore a key to the region’s forest history. Although much research has been done on Sami resource use and landscape impact, the context is often vaguely understood. READ MORE

4. 2. Boreal Forest Wildfire in a Changing Climate

   Author : Johan Eckdahl; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; boreal forest wildfire; carbon emissions; nutrient cycling; nitrogen; microbial community; plant community; climate chnge; secondary succession; Sweden; Fennoscandia; biodiversity; boreal skogsbrand; koldioxiduttsläpp; näringscykling; kväve; mirkobiellt samhälle; växtsamhälle; klimatförändring; sekundär succession; sverige; Fennoskandien; biologisk mångfald;

   Abstract : 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.

5. 3. Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support

   Author : Klas Lucander; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forest; boreal ecosystems; Forest biogeochemistry; Forest bioenergy; Boreal coniferous forest; base cations; Biogeochemical cycles; Dynamic Modelling; Carbon cycle; nitrogen cycle; decision support; policy-making; Weathering; Forestry; Land use change;

   Abstract : 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.

6. 4. Microclimate at range margins : Consequences for boreal forest understory species

   Author : Caroline Greiser; Kristoffer Hylander; Johan Ehrlén; Eric Meineri; Miska Luoto; Alistair Jump; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microclimate; species distribution; range dynamics; boreal forest; canopy cover; topography; soil moisture; air humidity; bryophytes; lichens; vascular plants; biotic interactions; forest management; biodiversity conservation; ekologi och evolution; Ecology and Evolution;

   Abstract : A warmer climate will shift species distributional range margins poleward, but near-ground microclimates may modify these shifts. Cold-adapted northern species at their rear edge may survive locally in microrefugia with a colder microclimate, and warm-adapted southern species at their leading edge may colonize stepping stone habitats with a warmer microclimate.

7. 5. Effects of drought on boreal forest understory species

   Author : Irena A. Koelemeijer; Kristoffer Hylander; Johan Asplund; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity conservation; boreal forests; bryophytes; canopy cover; climate change; drought; extreme climatic events; forest management; forest understory; fungi; lichens; plants; rainout shelter; soil communities; soil moisture; transplant experiment; Ecology and Evolution; ekologi och evolution;

   Abstract : Extreme climatic events, such as droughts, can have large effects on biodiversity. Drought effects in forest understories are variable over small spatial scales and can be exacerbated, or buffered, by the local vegetation structure, distance to forest edges, hydrology, and soil characteristics.
