1. 21. Molecular characterization and prevalence of hepatitis E virus in Swedish wild animals : a zoonotic perspective

   Författare :Jay Lin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Observation of chronic hepatitis E virus (HEV) in immunosuppressed patients, and unexplained high hepatitis E virus (HEV) prevalence in the human population raises public health concern. The aim of this thesis is to molecular characterize and investigate the prevalence of HEV in Swedish wild life and their association with HEV transmission to humans. LÄS MER

3. 22. Biochemical genetic variation, intraspecific genetic structure and postglacial evolution of select north European vertebrate species

   Författare :Ulf Gyllensten; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution biologi ; Populationsgenetik;

   Sammanfattning : Analysis of the tempo and mode of intraspecific differentiation provides important information for understanding subspeciation, for construction of taxonomic hierarchies within a species and for management of genetic variation in natural populations.The present thesis describes the genetic structure of natural populations of willow grouse (Lagopus tagopus L.

4. 23. Tracking Wild Boar and Hunters : Osteology of Wild Boar in Mesolithic South Scandinavia

   Författare :Ola Magnell; Historisk osteologi; []
   Nyckelord :HUMANIORA; HUMANITIES; Humanities; Mesolithic; body size; age estimation; taphonomy; hunting; osteology; Humaniora; wild boar;

   Sammanfattning : This thesis deals with the hunting of wild boar during the Mesolithic in South Scandinavia and the relationship between humans and wild game. The study is based on an analysis of osteological remains from sites in Scania, Sweden, dating from the Late Maglemose Culture to the Early Ertebølle Culture. LÄS MER

5. 24. Plant sex effects on biotic interactions in dioecious willow : plant sex-specific effects on interactions between Salix viminalis and its herbivores, pollinators and fungal disease

   Författare :Kim Moritz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Sex in dioecious plants affects interactions between plant individuals and the organisms consuming them. Plant-herbivore interactions are affected by plant sex across many plant families, and plant-pathogen infections can be strongly sex-biased. LÄS MER

7. 25. 'O neighbour, where art thou?' : spatial and social dynamics in wolverine and lynx, from individual space use to population distribution

   Författare :Malin Aronsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The organisation of individuals in space and time influences population structure and dynamics, and is important for our understanding of animal ecology. The aim of this thesis is to gain an increased understanding of the mechanisms driving the abundance and distribution of solitary carnivores, from individual space use to population-level distribution.
