Rabies hos flaggermus er utbredt over store deler av verden og er også registrert i mange områder i Europa. Fjorten av Europas rundt 40 arter er rapportert å ha vært eksponert for rabiesvirus enten ved påvisning av viruset eller ved funn av antistoffer i blod. Rabiesvirus som forekommer hos flaggermus i Europa kalles European Bat Lyssavirus (EBLV) og finnes i to varianter, EBLV1 og EBLV2 (også kalt ...

To determine the present-day community composition of siliceous Rhizaria (Radiolaria and Phaeodaria) in Norwegian fjords, plankton tows were conducted in south-western and northern Norwegian fjords in September 2016. The mean total abundance of radiolarians was 306 m^–3 in the Sognefjord complex, which was the southern research site, and, in the north, 945 m^–3 in Malangen and ...

1. Actuarial senescence, the decline of survival with age, is well documented in the wild. Rates of senescence vary widely between taxa, to some extent also between sexes, with the fastest life histories showing the highest rates of senescence. Few studies have investigated differences in senescence among populations of the same species, although such variation is expected from population-level ...

Rangifer (caribou/reindeer) management has been suggested to mitigate the temperature- driven transition of Arctic tundra into a shrubland state, yet how this happens is uncertain. Here we study this much focused ecosystem state transition in riparian areas, where palatable willows (Salix) are dominant tall shrubs and highly responsive to climate change. For the state transition to take place, ...

The exotic Japanese jumping snail, Ovachlamys fulgens, was first recorded in Santa Catarina state, Brazil, in 2013. Based on data gathered from the literature, natural history collections, field samplings, and the iNaturalist platform, we assess its current distribution in the country. Our data show that the jumping snail has had a dramatic range expansion since its introduction, reaching six ...

<p><i>Background - </i>Gene expression changes that govern essential biological processes can occur at the cell-specific level. To gain insight into such events, laser microdissection is applied to cut out specific cells or tissues from which RNA for gene expression analysis is isolated. However, the preparation of plant tissue sections for laser microdissection and subsequent RNA isolation usually ...

Productive tundra plant communities composed of a variety of fast growing herbaceous and woody plants are likely to attract mammalian herbivores. Such vegetation is likely to respond to different-sized herbivores more rapidly than currently acknowledged from the tundra. Accentuated by currently changing populations of arctic mammals there is a need to understand impacts of different-sized herbivores ...

I denne studien har jeg undersøkt regnskapsmessig rapporteringspraksis om eksponering mot finansiell risiko innenfor den norske hvitfiskindustrien. Formålet med studien er å undersøke hvorvidt rapporteringen er i samsvar med gjeldene norsk lovgivning og god regnskapsskikk på området. Jeg har i tillegg sett på flere forhold som kan være med å påvirke regnskapspraksisen. Bakgrunnen for valg av ...

Land cover maps are the basic data layer required for understanding and modeling ecological patterns and processes. The Circumpolar Arctic Vegetation Map (CAVM), produced in 2003, has been widely used as a base map for studies in the arctic tundra biome. However, the relatively coarse resolution and vector format of the map were not compatible with many other data sets. We present a new version of ...

We consider a pie-splitting game involving three committee members. In response to the large literature on sequential procedures in this type of game, we propose an institution that is inspired by auction theory. The (sealed) bids of the players are proposals for a distribution of the pie and are given simultaneously. If any of the bids is preferred to all others in a pairwise comparison (i.e. ...
