Assessment of possible adverse consequences for biodiversity when planting vascular plants outside their natural range in Norway -(VKM)
(Research report; Forskningsrapport, 2021-06-25)We sow or plant vascular plant species on a large scale in revegetation and restoration projects in Norway today. Some of the species used are already found in Norway, but many of the species, subspecies or populations used though native are not local, that is, they are <i>regionally alien</i>. A regionally alien species is a species that is native to Norway (has been in Norway since 1800) somewhere ... -
Assessment of the risk to Norwegian biodiversity from import and keeping of crustaceans in freshwater aquaria. Scientific Opinion of the Panel on Alien Organisms and Trade in Endangered Species of the Norwegian Scientific Committee for Food and Environment
(Research report; Forskningsrapport, 2021)The Norwegian Scientific Committee for Food and Environment (VKM) was requested by the Norwegian Environment Agency to assess the risk of negative impacts to biodiversity in Norway resulting from import of crustacean decapods for keeping in freshwater aquariums.<p> <p>VKM was asked to 1) list species of crayfish, crabs and shrimps that are currently kept in freshwater aquaria in Norway, and ... -
Assessment of the risks to honey bees and biodiversity in Norway posed by the predatory wasp species Vespa velutina and V. mandarinia - Scientific Opinion of the Panel on Alien Organisms and Trade in Endangered species of the Norwegian Scientific Committee for Food and Enviroment
(Research report; Forskningsrapport, 2022-02-21)Med varmere klima er det mulig at asiatisk geithams (Vespa velutina) kan spre seg til Norge. Det er usannsynlig at japansk geithams (Vespa mandarina) vil spre seg til Norge. -
High-throughput sequencing of African chikanda cake highlights conservation challenges in orchids
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-01)Chikanda is a traditional dish made with wild-harvested ground orchid tubers belonging to three orchidioid genera, Disa, Satyrium and Habenaria, all of which are CITES appendix II-listed. Identification of collected orchid tubers is very difficult and documentation of constituent species in prepared chikanda has hitherto been impossible. Here amplicon metabarcoding was used in samples of six prepared ... -
Importation of roughage to Norway - Implications for plant and animal health, zoonoses, and biodiversity. Opinion of the scientific committee of the Norwegian Scientific Committee for Food and Enviroment
(Research report; Forskningsrapport, 2022-02-18)Det er stor usikkerhet om import av grovfôr til Norge kan føre med seg planteskadegjørere, invaderende planter og smittestoff som kan forårsake sykdom hos dyr og mennesker. -

Kunnskapsstatus for bruk av molekylære verktøy i kartlegging og overvåkning av biologisk mangfold i marine miljø
(Research report; Forskningsrapport, 2021-06-02)Denne rapporten er bestilt av Miljødirektoratet fra NorBOL (Norwegian Barcode of Life), et nasjonalt nettverk av forskningsinstitusjoner som koordineres av NTNU Vitenskapsmuseet. Universitetsmuseet i Bergen har hatt prosjektledelsen. Rapporten gir en oppsummering av dagens status på DNA-basert metodikk som verktøy i kartlegging og overvåking av biologisk mangfold i det marine miljø. Fokus har vært ... -
Plant biodiversity assessment through soil eDNA reflects temporal and local diversity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-12)1. Several studies have shown the potential of eDNA-based proxies for plant identification, but little is known about their spatial and temporal resolution. This limits its use for plant biodiversity assessments and monitoring of vegetation responses to environmental changes. Here we calibrate the temporal and spatial plant signals detected with soil eDNA surveys by comparing with a standard visual ... -
Status and trade assessment of parrots listed in CITES Appendix I. Scientific Opinion of the Panel on Alien Organisms and trade in endangered species (CITES)
(Research report; Forskningsrapport, 2020-12-18)Parrots are one of the most species-rich groups of birds of which the majority inhabits tropical and subtropical forests. Nearly one-third of parrots are threatened with extinction (IUCN categories CR, EN or VU) and more than half of the world’s parrot species are assumed to be decreasing in numbers. Parrots are popular pets on all continents, mainly due to their colourful feathers, their capacity ...
