11. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles
Sammanfattning : 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. LÄS MER
12. Conservation genomics in inbred Scandinavian wolves using bioinformatic methods
Sammanfattning : 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. LÄS MER
13. Immunogenetic variation along the latitudinal gradient in Scandinavian anuran species : Evolutionary processes, demography and infection
Sammanfattning : 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. LÄS MER
14. Nutrient use strategies of plants of various life-forms in a subarctic environment : Nutrient conservation as an adaption to infertile habitats
Sammanfattning : 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). LÄS MER
15. Microarray Analysis of mRNA Decay Assays and Prediction of Drug Target Conservation
Sammanfattning : 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. LÄS MER
