6. Ecology across Boundaries : Food web coupling among and within ecosystems
Sammanfattning : Cross-boundary movements of energy and material are ubiquitous. Freshwater ecosystems receive nutrients, dissolved, and particulate organic matter from adjacent terrestrial ecosystems, whereas terrestrial ecosystems mainly receive prey organisms and detritus deposited by physical processes such as floods from freshwater ecosystems.

7. Linkage maps in studies of genetic variation - examples from Beta vulgaris
Sammanfattning : Today, most studies of genetic variation utilise molecular markers, making it possible to detect variation at the DNA level. This has greatly facilitated studies of genetic variation in population and evolutionary genetics, systematics and transmission genetics. LÄS MER
8. Quantitative Trait Evolution in a Changing Environment in a Seed Beetle
Sammanfattning : During the last decades the climate has been changing more rapidly than in the preceding periods. This is for instance characterized by an increase in temperature. Interestingly, such changes in the environment are not necessarily constant over time as they often show high levels of fluctuation. LÄS MER
9. Multiple sclerosis linkage analysis and DNA variation in a complex trait
Sammanfattning : Multiple sclerosis is a life-long disease affecting approximately 11.000 individuals in Sweden today. It is the second most common cause of neurological disability amongst young adults, only outnumbered by traffic accidents. Genetic epidemiological studies indicate that genetic factors contribute to the susceptibility of MS. LÄS MER
10. Advances in studying the role of genetic divergence and recombination in adaptation in non-model species
Sammanfattning : Understanding the role of genetic divergence and recombination in adaptation is crucial to understanding the evolutionary potential of species since they can directly affect the levels of genetic variation present within populations or species. Genetic variation in the functional parts of the genome such as exons or regulatory regions is the raw material for evolution, because natural selection can only operate on phenotypic variation already present in the population.
