  4. 2. Gene Mapping in Ficedula Flycatchers

    Author : Niclas Backström; Hans Ellegren; Juha Merilä; Uppsala universitet; []
    Keywords : collared flycatcher; SNP; linkage disequilibrium; genetic map; pedigree;

    Abstract : 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. READ MORE

  5. 3. Effects of Agriculture on Abundance, Genetic Diversity and Fitness in the Common Frog, Rana temporaria

    Author : Markus Johansson; Anssi Laurila; Juha Merilä; Craig R. Primmer; Michael W. Bruford; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; agriculture; agrochemicals; amphibians; effective population size; genetic diversity; genetic structure; hierarchical sampling; microsatellites; Rana temporaria; Biologi; Biology; Biologi;

    Abstract : 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. READ MORE

  6. 4. Local adaptation in life history traits and population size estimation of aquatic organisms

    Author : Konrad Karlsson; Monika Winder; Johan Ehrlén; Juha Merilä; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; local adaptation; intraspecific variation; niche partitioning; life history; global warming; recreational angling; spatial capture–recapture; Marine Ecology; marin ekologi;

    Abstract : 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. READ MORE

  7. 5. Phenotypic plasticity and local adaptation in island populations of Rana temporaria

    Author : Martin Lind; Frank Johansson; Juha Merilä; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Costs of plasticity; Developmental threshold; FST; Local adaptation; Phenotypic plasticity; Pool drying; QST; Freshwater ecology; Limnisk ekologi; zooekologi; Animal Ecology;

    Abstract : 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. READ MORE
