   Sammanfattning : The subject of this thesis is the nature of evaluative terms and concepts. It investigates various phenomena that distinguish evaluative discourse from other types of language use. LÄS MER

3. 7. Hybridisation between introduced brown hares and native mountain hares in Sweden

   Författare :Carl-Gustaf Thulin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; naturvårdsbiologi; Conservation Biology;

   Sammanfattning : To investigate the extent and effect of hybridisation between wild sympatric populations of introduced brown hares (Lepus europaeus) and native mountain hares (L.timidus) in Sweden, the geographic distribution of genetic variation in mitochondrial DNA (mtDNA) and nuclear DNA microsatellite markers were analysed within and between the two species and their presumed hybrids.

4. 8. Lagovirus europaeus GI.2/RHDV2 (Rabbit Haemorrhagic Disease Virus 2) : expanding the paradigm of a pathogenic lagovirus

   Författare :Aleksija Neimane; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Rabbit haemorrhagic disease (RHD) was first detected in 1984 and quickly spread among wild and domestic European rabbits (Oryctolagus cuniculus) throughout the world. RHD and European brown hare syndrome (EBHS), a related disease of hares (Lepus spp.), are caused by pathogenic lagoviruses of the Family Caliciviridae. LÄS MER

5. 9. Cycles of voles, predators, and alternative prey in boreal Sweden

   Författare :Birger Hörnfeldt; S. Erlinge; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3-4 year cycles; Clethrionomys glareolus; Clethrionomys rufocanus; Microtus agrestis; snap-trapping; rate of change; population regulation; delayed density-dependence; time-lag mechanism; seasonality; predation; food; predator avoidance; foraging behaviour; Aegolius funereus; nest boxes; numerical response; nomadism; Vulpes vulpes; Sarcoptes scabiei vulpes; Lepus timidus; Francisella tularensis; Tetraonidae; hunting statistics; zooekologi; Animal Ecology;

   Sammanfattning : Bank voles, grey-sided voles, and field voles had synchronous 3-4 year density cycles with variable amplitudes which averaged about 200-fold in each species. Cycles of vole predators (red fox and Tengmalm's owl), and their (foxes') alternative prey (mountain hare and forest grouse) lagged behind the vole cycles. LÄS MER

7. 10. Phylogenetic relationships and species richness of coprophilous ascomycetes

   Författare :Åsa Nyberg Kruys; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ß-tubulin; Bayesian analysis; dung; forage; fungi; moose; parsimony; phylogeny; Pleosporales; spore dispersal; Sporormiaceae; Terrestrial ecology; Terrestisk ekologi;

   Sammanfattning : Coprophilous ascomycetes are a diverse group of saprobes, of which many belong to three families, Delitschiaceae, Phaeotrichaceae and Sporormiaceae, within the large order Pleosporales. The natural relationships and circumscription of these families are unclear, especially within the family Sporormiaceae, where the generic delimitation have been questioned. LÄS MER
