  2. 1. Charting biodiversity : Scuttle flies and other poorly known insects in Sweden

    Author : Sibylle Häggqvist; Fredrik Ronquist; Jeff Skevinton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Biodiversity has fascinated people in all times. We as a species are part of the global ecosystem and our survival depends on many other species around us. Charting biodiversity, however, has proven more difficult than one could imagine. READ MORE

  4. 2. Towards inclusion of Biodiversity in Life Cycle Assessment

    Author : Emke Vrasdonk; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Impact assessment; Biodiversity; LCA; eDNA; Life Cycle Assessment; Sustainability; Reference situation; Land Use; Biodiversity conservation; Metabarcoding; Indicators;

    Abstract : Biodiversity- crucial for ecosystem health and its products and services – is being lost at an alarming rate. While it is clear that human consumption is the main driving force of the considerable losses, conversion of natural habitats for production is continuing and the subsequent intensification of those systems is likely to cause even further biodiversity decay.

  5. 3. Wooded or treeless pastures? : Linking policy, farmers' decisions and biodiversity

    Author : Simon Jakobsson; Regina Lindborg; Sara A O Cousins; Jan Plue; Tim Benton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bat; biodiversity; bird; canopy cover; Common Agricultural Policy; European Union; farmer; functional diversity; germination; grassland; multi-taxa; pasture; plant; policy; seed sowing; tree density; trees; Physical Geography; naturgeografi;

    Abstract : Worldwide, biodiversity conservation is one of the key challenges for a sustainable future of nature and society. It is particularly important to preserve high quality habitats within otherwise intensively managed agricultural landscapes. READ MORE

  6. 4. The Biodiversity of Hydrogenases in Frankia : Characterization, regulation and phylogeny

    Author : Melakeselam Leul Zerihun; Anita Sellstedt; Kornel Kovács; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Frankia; immunoblotting; gene expression; uptake hydrogenase; hydrogen-evolving hydrogenase; nickel; phylogeny; Molecular biology; Molekylärbiologi;

    Abstract : All the eighteen Frankia strains isolated from ten different actinorhizal host plants showed uptake hydrogenase activity. The activity of this enzyme is further increased by addition of nickel. Nickel also enhanced the degree of hydrogenase transfer into the membranes of Frankia, indicating the role of this metal in the processing of this enzyme. READ MORE

  7. 5. Fungal disease dynamics, genetic variation and biodiversity-yield relationships : — a study along a gradient of coffee management in southwestern Ethiopia

    Author : Beyene Zewdie Hailu; Kristoffer Hylander; Ayco J.M Tack; Jacques Avelino; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Armillaria root rot; biodiversity; biodiversity-yield trade-offs; coffee; Coffea arabica; coffee berry disease; coffee leaf rust; coffee wilt disease; coffee yield; genetic composition; genetic diversity; hyperparasite; management intensity gradient; southwestern Ethiopia; Plant Ecology; växtekologi;

    Abstract : Intensification of agricultural systems is a major threat to the associated biodiversity and could also affect the dynamics of pests and pathogens. One such system that is currently under an intensification trajectory is the production of Arabica coffee. READ MORE
