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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Emke Vrasdonk; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Impact assessment; Biodiversity; LCA; eDNA; Life Cycle Assessment; Sustainability; Reference situation; Land Use; Biodiversity conservation; Metabarcoding; Indicators;

    Sammanfattning : 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.

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 5. The importance of trust. : a study of knowledge production of biodiversity

    Författare :Karin M Gustafsson; Rolf Lidskog; Christine Roman; Mark Elam; Örebro universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; trust; knowledge; biological diversity; biodiversity; environmental problems; discourse analysis; Mode-1 Mode-2; SSK; STS; Sociologi; Sociology;

    Sammanfattning : The loss of biological diversity is one of today’s greatest environmental problems. Scientific knowledge is typically presented as the premise to solve this problem. However, science alone is not sufficient to produce knowledge of biodiversity. Other actors are also involved in knowledge production. LÄS MER
