1. Population-level consequences of variation
Abstract : Consequences of within population variation have recently attracted an increased interest in evolutionary ecology research. Theoretical models suggest important population-level consequences, but many of these predictions still remain to be tested. READ MORE

2. The evolutionary ecology of plant reproductive diversity and floral signals : Mating system and floral scent in Arabis alpina
Abstract : Flowering plants display an extraordinary floral- and reproductive diversity. Variation in the size, shape, colour and scent of flowers, and in systems and strategies of mating, is ubiquitous in comparisons of different species, but also exists among different conspecific populations.

3. Fish population responses to climate change : Causes and consequences
Abstract : Lake environments are heterogeneous, and animals show a variety of adaptations to deal with this heterogeneity. Fish often show intraspecific variation in diet, metabolism, and behavior, corresponding to their habitat use. READ MORE

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

5. Local Adaptation, Countergradient Variation and Ecological Genetics of Life-history Traits in Rana Temporaria
Abstract : The main aim of this work was to identify local adaptation processes in amphibian populations, thereby improving the general understanding of genetics and mechanisms behind the evolution and maintenance of biological diversity. Phenotypic and genetic variation in life-history traits was studied within and between populations common frog (Rana temporaria) populations along a 1600 km transect from southern Sweden to northern Finland.
