  2. 1. On the Regulation of Ornithine Decarboxylase

    Author : Eva Lövkvist Wallström; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; Crithidia fasciculata.; polyamines; Ornithine decarboxylase; translational control; osmolarity; untranslated region; COS cells; CHO cells; transfection; protein turnover; PEST region;

    Abstract : The polyamines putrescine, spermidine and spermine have been shown to be involved in cell growth and differentiation, and are considered to be crucial components of the living cell. The synthesis of polyamines in the cell is strictly regulated. READ MORE

    Abstract : In today´s intensively managed landscape, very few forests with old-growth characteristics and little human impact exist. One of the rare exceptions is pine forests on rocky soils, a forest type which has probably escaped extensive human use because of its low productivity. READ MORE

  5. 3. In the wake of the Green Revolution : Environmental and socioeconomic consequences of intensive rice agriculture - The Problems of weeds in Muda, Malaysia

    Author : Magnus Jirström; Institutionen för kulturgeografi och ekonomisk geografi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; intensification; land degradation; rice agriculture; IPM integrated pest management ; Social geography; sustainable agriculture; Green Revolution; Socialgeografi;

    Abstract : The agricultural intensification strategies represented by the Green Revolution have since the mid-1960s had a very positive impact on food-grain production in Asia. Presently, however, a post-Green Revolution phase of declining growth in output and productivity is experienced in many of the areas where intensification took place. READ MORE

  6. 4. Natural enemies: Functional aspects of local management in agricultural landscapes

    Author : Helena Hanson; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agricultural intensification; sustainable agriculture; land use; management intensity; landscape scale; ecosystem services; biological control; species trait; pesticides; predatory arthropods; parasitoids; pollen beetles;

    Abstract : Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. READ MORE

  7. 5. Impacts of Antifouling Compounds on Photosynthesis, Community Tolerance and psbA Genes in Marine Periphyton

    Author : Martin Eriksson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PICT; antifouling; periphyton; photosynthesis; D1; psbA; tolerance; resistance; periphyton;

    Abstract : Toxicants can act as selective pressures in the environment, eliminating sensitive genotypes or species and favouring tolerant ones. Such toxicant-induced selection can be detected in natura... READ MORE
