Scandinavia was one of the last geographic areas in Europe to become habitable for humans after the Last Glacial Maximum (LGM). However, the routes and genetic composition of these postglacial migrants remain unclear. We sequenced the genomes, up to 57x coverage, of seven hunter-gatherers excavated across Scandinavia and dated from 9,500-6,000 year...
In cities today, vast amounts of nutrients are being wasted. Improvement in nutrient management within agriculture can contribute to a more sustainable society. Reusing nutrients in agriculture could aid in creating a more circular system, where organic fertilizers can be used instead of chemical fertilizers. Urine is a liquid which has a high nutr...
Male and female plants of dioecious species often experience differential herbivory, possibly due to differences in defences such as secondary metabolite composition or nutritional quality. These plant sex effects on herbivory have been extensively studied for plant individuals, but not for stands/populations. For mobile herbivores, such as deer, s...
Sediments underlying hypoxic or anoxic water bodies constitute a net source of phosphorus to the bottom water. This source has the potential to enhance eutrophication. Benthic fluxes of dissolved phosphorus, iron and manganese were measured from hypoxic, normoxic, and normoxic bioturbated by the invasive polychaete Marenzelleria arctia sediment in ...
Syftet med denna studie är att ta reda på hur de tre dimensionerna av hållbar utveckling förekommer i elevernas uppfattningar av begreppet, samt vilka aspekter av dimensionerna som kan kopplas till elevernas uppfattningar. Studiens frågeställningar har undersökts med hjälp av kvalitativa intervjuer. Empiri har samlats in under fyra intervjuer av se...
Abstract Introduction Failure in the mechanism of self-tolerance in T or B cells can lead to autoimmunity. One of the autoimmune diseases is rheumatoid arthritis (RA), which is a chronic inflammatory disease of unknown cause and is characterized by systemic inflammation, autoantibodies and joint destruction. Serology is crucial for the classificati...
Cognitive processes are often biased by emotions. In humans, affective disorders are accompanied by pessimistic judgement, while optimistic judgement is linked to emotional stability. Similar to humans, animals tend to interpret ambiguous stimuli negatively after experiencing stressful events, although the long-lasting impact on judgement bias has ...
The world’s most numerous bird, the domestic chicken, and their wild ancestor, the red junglefowl, have long been used as model species for animal behaviour research. Recently, this research has advanced our understanding of the social behaviour, personality, and cognition of fowl, and demonstrated their sophisticated behaviour and cognitive skills...
At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Accepted. Paper 4: Manuscript.
The aim of this study was to investigate how well the biological indexes in the north of Sweden matches with the physicochemical conditions in streams, and to evaluate whether the deformations of diatom shells has a connection to heavy metal conditions in streams. The sampling areas include nineteen different locations. As the water-chemical condit...
