  2. 1. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation

    Author : Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; climate change; compost; floral resources; grasslands; in-situ experiments; mowing; nectar; open-top chambers; plants; rain-out shelters; sheep grazing; soil amendments; summer drought; winter warming; naturgeografi; Physical Geography;

    Abstract : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. READ MORE

  4. 2. On Sustainability of Biomass for Energy and the Governance Thereof

    Author : Oskar Englund; Virginia Dale; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sustainability; land use; spatial modelling; biomass production; certification; environmental legislation; biomass resources; ecosystem services; Bioenergy; GIS; biodiversity; governance;

    Abstract : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. READ MORE

  5. 3. 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.

  6. 4. Travelling through time : Students’ interpretation of evolutionary time in dynamic visualizations

    Author : Jörgen Stenlund; Lena Tibell; Konrad Schönborn; Niklas Gericke; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolution; visualization; time; learning; threshold; zooming;

    Abstract : Evolutionary knowledge is important to understand and address contemporary challenges such as loss of biodiversity, climate change and antibiotic resistance. An important aspect that is considered to be a threshold concept in teaching and learning about evolution is the time it involves. READ MORE

  7. 5. Carbon exchange in boreal ecosystems: upscaling and the impacts of natural disturbances

    Author : Julia Kelly; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Carbon fluxes; CH4; Climate change; CO2; Drought; Ecosystem respiration; Forest; Peatland; Remote sensing; Temperature; Thermal camera; UAV; Wildfire;

    Abstract : Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. READ MORE
