  1. 1. Chlorine Cycling in Terrestrial Environments

    Författare :Malin Montelius; David Bastviken; Teresia Svensson; Katarina Abrahamsson; Linköpings universitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES; Chloride; organic chlorine; chlorination; dechlorination; 36Cl; risk assessment modelling; Klorid; organiskt klor; klorering; deklorering; klor-36; riskmodellering;

    Sammanfattning : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. LÄS MER

    Sammanfattning : The purpose of this licentiate thesis is to gather and classify information about traditional vegetative propagation of perennial herbaceous plants. This thesis is the first, self-contained part of a survey of propagation methods used by horticulturists. LÄS MER

  4. 4. Insect pollination of oilseed rape

    Författare :Sandra Lindström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. LÄS MER

  5. 5. The complexity of seafood trade relations across scales

    Författare :Laura G. Elsler; Maja Schlüter; Simon A. Levin; Anne-Sophie Crépin; Jennifer Jacquet; Stockholms universitet; []

    Sammanfattning : There is growing concern about the unprecedented rise in international seafood trade that relies on increasingly overused and climate-driven fisheries. Seafood trade relations, the multi-dimensional relations between fishers, traders, and countries for seafood exchange and other interactions, are central in the process of globalization. LÄS MER
