2. 1. Wood-living beetle diversity and Swedish forest management

   Author : Oskar Gran; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; forestry; harvest; insects; landscape; management;

   Abstract : Humans have impacted Fennoscandian forests for thousands of years, through grazing, burning, and since the industrial revolution increasingly through efficient industrial forestry. These impacts have changed the composition and structure of these forests, by reducing forest age, simplifying forest structure, and reducing the amount of broadleaved trees, among other things.

4. 2. Sustainable agriculture : From global challenges to local land management

   Author : John Livsey; Stefano Manzoni; Steve Lyon; Esteban Jobbágy; Stockholms universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; agriculture; irrigation; nutrients; soil properties; water management; fertilisation; Physical Geography; naturgeografi;

   Abstract : Despite the success of agriculture management practices in increasing the availability of food needed to meet the requirements of the expanding global population, there are increasing demands placed on the resources on which the sector depends. Opportunities for the development of agricultural systems are constrained by increasing competition, from other sectors, for shared resources. READ MORE

5. 3. Effects of forest management on greenhouse gas fluxes in a boreal forest

   Author : Patrik Vestin; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : Forest management; Greenhouse gas fluxes; Clear-cutting; Thinning; Stump harvesting; Selective cutting; Eddy-covariance; Flux-gradient; Greenhouse gas budgets; CO2; CH4; N2O;

   Abstract : Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies.

6. 4. Plant community assembly during succession from arable fields to semi-natural grassland

   Author : Barbara Christine Schmid; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; diversity; arable-to-grassland succession; space-for-time approach; land-use history; plant community assembly; grazing management; connectivity measures; dispersal vector; vascular plants; grassland specialist conservation;

   Abstract : Large areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. READ MORE

7. 5. Cost Effective Maintenance for Competitve Advantages

   Author : Imad Alsyouf; Basim Al-Najjar; Uday Kumar; Växjö universitet; []
