  2. 11. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles

    Author : Anna Hagelin; Eva Bergman; Fleming Ian; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atlantic salmon; conservation; migration; spawning; hydropower; competition; juveniles; brown trout; hatchery reared; fallback; delay; Biology; Biologi;

    Abstract : Hydropower dams represent one of the major threats to river ecosystems today. The dams block migratory routes in many rivers, which is problematic for migratory fish species. Trap-and-transport may be an alternative to fish passage solutions, as a strategy to compensate for lost river connectivity. READ MORE

  4. 12. Conservation genomics in inbred Scandinavian wolves using bioinformatic methods

    Author : Linnéa Smeds; Hans Ellegren; Giorgio Bertorelle; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conservation genomics; Canis lupus; bioinformatics; Y chromosome; admixture; genetic load; structural variation; GWAS; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : With the recent and unprecedented progress in retrieving DNA sequence information from a large number of individuals of any species, conservation genetic research has entered a new phase. Specifically, it has become possible to study how genomes of endangered species respond to reductions in population size. READ MORE

  5. 13. Immunogenetic variation along the latitudinal gradient in Scandinavian anuran species : Evolutionary processes, demography and infection

    Author : Maria Cortazar-Chinarro; Jacob Höglund; Anssi Laurila; Yvonne Meyer-Lucht; Helena Westerdahl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biologi; Biology; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : The evolutionary and demographic processes affecting how genetic variation is partitioned and distributed over large geographical scales is of fundamental importance for our understanding of how organisms may adapt to their environments. Northern peripheral populations generally have lower genetic variation and individuals in these populations may therefore face difficulties adapting to their local environment. READ MORE

  6. 14. Nutrient use strategies of plants of various life-forms in a subarctic environment : Nutrient conservation as an adaption to infertile habitats

    Author : Rolf Lutz Eckstein; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Mean residence time; Nutrient productivity; Nutrient use efficiency; Plant strategies; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Abstract : Plant performance in relation to limiting nutrients was analysed using the concept of nutrient use efficiency (NUE). NUE can be decomposed into (1) the nutrient productivity (aNP) and (2) the mean residence time (MRT). READ MORE

  7. 15. Microarray Analysis of mRNA Decay Assays and Prediction of Drug Target Conservation

    Author : Alexandra Jauhiainen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microarray analysis; mRNA decay; evolutionary conservation; ecotoxicology; environmental risk assessments; ecotoxicology;

    Abstract : This thesis contains two papers concerning (I) the evolutionary conservation of drug targets and its potential use in environmental risk assessments and (II) mRNA degradation as a control mechanism during osmotic stress in the yeast S. cerevisiae. Environmental risk assessments are needed for the approval of new pharmaceutical compounds. READ MORE
