Forskningsprosjekter
Vi har et hovedfokus på Amazonas og de tropiske Andesfjellene, men studentene våre arbeider i mange ulike tropiske områder. Nedenfor beskriver vi noen av hovedprosjektene våre. Disse inkluderer økologi i Amazonas’ flommarker, tåkeskoger i Andesfjellene og arealbruksendringer, samt forskning på NTFP-er.
Kaskadeeffekter av jakt og fiske for økosystemtjenester i Amazonas’ skoger
Dette prosjektet – også kjent som Amazon Biodiversity and Carbon Expeditions (ABC Expeditions) – har som mål å undersøke i hvilken grad (over)høsting av store terrestriske og akvatiske fruktetere er en menneskeskapt driver for endringer i karbonlagre i strukturelt uberørte Amazonas-skoger. Målet er å forstå hvilke konsekvenser avskoging av dyrelivet (defaunation) har for karbonlagring i ellers intakte tropiske skoger.
Balansering av naturmangfold og utvikling i Amazonas’ våtmarker
Dette prosjektet, finansiert av BiodivERsA, undersøker truslene mot Amazonas’ flommarkshabitater som følge av utvikling og ressursutvinning. Med utgangspunkt i flere tiår med forskning på flommarker, skal prosjektet:
- forbedre karakteriseringen av hvitvann-flommarker og flomdynamikk
- skalere opp eksisterende datasett om fisk, flommarksskoger og planteplankton
- vurdere hvordan klima, arealbruksendringer og demninger påvirker disse habitatene
- involvere et bredt spekter av lokale og regionale interessenter for å finne bærekraftige strategier for bevaring av våtmarker
Økologi og sesongvariasjon i Amazonas’ flommarksskoger
Hvert år oversvømmes Amazonas’ flommarksskoger av elver som går over sine bredder. Plante- og dyreliv må derfor håndtere skiftende terrestriske og akvatiske faser. Vi undersøker flora og fauna i flommarkene og hvordan sesongflommen påvirker dem. Vi er også opptatt av å identifisere trusler mot disse økosystemene og forstå deres konsekvenser.
Migrasjon hos vannfugler i Amazonas
Kunnskapen om fugletrekk innen Sør-Amerika er fortsatt begrenset. Sesongflommer tvinger noen vannfuglarter til å migrere årlig, men vi vet lite om hvordan de bruker det komplekse amazonske landskapet gjennom året. Vi kartlegger trekkruter, trekkatferd og viktige raste- og overvintringsområder – med mål om å styrke bevaringen av disse artene.
Konsekvenser av tropisk landbruk
Vi undersøker hvordan tropisk landbruk best kan forvaltes og utvides for å minimere tap av biologisk mangfold. Dette innebærer forskning på om land-sparing eller land-deling gir best resultater, og hvordan landbruk påvirker biodiversitet på ulike skalaer. Fokusområder inkluderer oljepalmeplantasjer i Colombias Llanos og kvegdrift i de tropiske Andesfjellene.

Forvaltning av naturressurser
Uttak av ressurser – inkludert jakt, innsamling av andre ikke-tømmerprodukter og fiske – er lovlig i alle urfolksterritorier og andre flerbruks- og bærekraftige utviklingsreservater i den brasilianske Amazonas. Vi dokumenterer ressursbruken og utarbeider retningslinjer for bærekraftig forvaltning.
Livshistorie hos paranøtt-treet
Paranøtttreet (Bertholletia excelsa) gir ett av de viktigste ikke-tømmerbaserte skogproduktene i tropene – paranøtten. Vi forsker på hele treets livshistorie, inkludert frukt- og blomsterproduksjon, frøspredning, etablerings- og gjenvekstsucces og vekstrater.
