1. Genetic and quantitative trait variation in natural bird population
Sammanfattning : .... LÄS MER
2. Gene Mapping in Ficedula Flycatchers
Sammanfattning : In order to get full understanding of how evolution proceeds in natural settings it is necessary to reveal the genetic basis of the phenotypic traits that play a role for individual fitness in different environments. There are a few possible approaches, most of which stem from traditional mapping efforts in domestic animals and other model species. LÄS MER
3. Effects of Agriculture on Abundance, Genetic Diversity and Fitness in the Common Frog, Rana temporaria
Sammanfattning : The aims of this thesis were to evaluate the effects of agriculture on amphibians in terms of (i) population genetic consequences of agriculture-induced spatial changes of the landscape and (ii) local adaptation and tolerance to frequently used agrochemicals. The study was performed using the common frog Rana temporaria as a model. LÄS MER
4. Local adaptation in life history traits and population size estimation of aquatic organisms
Sammanfattning : Human society is dependent on healthy aquatic ecosystems for our basic needs and well-being. Therefore, knowledge about how organisms respond and interact with their environments is pivotal. LÄS MER
5. Phenotypic plasticity and local adaptation in island populations of Rana temporaria
Sammanfattning : Phenotypic plasticity is the ability of a genotype to express different phenotypes in different environments. Despite its common occurrence, few have investigated differences in plasticity between populations, the selection pressures responsible for it, and costs and constraints associated with it. LÄS MER
