  2. 1. Plant Population Dynamics and Conservation in Wooded Hay-Meadows – Effects of Intensified Management

    Author : Lotta Wallin; Brita M. Svensson; Mikael Lönn; Johan Ehrlén; Uppsala universitet; []
    Keywords : Biology; coordinates; demographic model; dispersal; hay-meadow; Hypochoeris maculata; litter; management; Polygala amarella; stochastic modelling; Succisa pratensis; Biologi;

    Abstract : The decrease in number and area of managed hay-meadows over the last century, in combination with the reduction of traditional management, threatens the biodiversity connected to these habitats. I experimentally examined how management intensity affected meadow characteristics and long-term population viability of three vascular plant species in wooded hay-meadows on the Swedish island of Gotland in the Baltic Sea.

  4. 2. Studies on leaching and decomposition of litter

    Author : Nils Nykvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : .... READ MORE

  5. 3. The interaction between carbon and nitrogen during litter decomposition

    Author : Linnea Berglund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Litter decomposition is essential for the cycling of elements in ecosystems. How carbon (C) and nitrogen (N) interact during litter decomposition is, however, not yet fully understood. This thesis studies litter decomposition with the aim of increasing our understanding of the interactions between C and N. READ MORE

  6. 4. Impact of litter size on sow health and welfare

    Author : Emma Andersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Genetic improvement of litter size has been the main breeding goal in piglet production during the last decades, resulting in a steady increase in total number of born piglets in each litter both in Sweden and in other European countries. It has been suggested that large litters pose a major welfare problem for sows and piglets. READ MORE

  7. 5. Fungal and bacterial contributions to decomposition in terrestrial and aquatic ecosystems

    Author : Margarida Soares; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fungi; bacteria; microbial carbon use efficiency; litter decomposition; priming effect; heavy metal stress;

    Abstract : Microbial decomposers process a great majority of net primary production in the biosphere and regulate carbon (C) and nutrient cycling. Microbial communities are extremely diverse and often disregarded from global C-cycling models, but one strategy to overcome this challenge is to focus on the major decomposer groups: fungi and bacteria.
