Ecosystem carbon stocks in Danish deciduous forests: impact of land-use history and management on major carbon pools
Solhus, Tonje Rostad (Master thesis, 2023)Skog er viktig karbonsluk, og bidrar med å hjelpe å dempe klimaendringene. Bærekraftig forvaltning av skogen er nødvendig for å kunne maksimere effekten av karbonslukene. Effekten av tidligere arealbruk, og nåværende ... -
Functional traits of Epirrita autumnata (autumnal moth) across space and time: An entomological collection-based study
García Castro, Federico (Master thesis, 2024)Naturhistoriske samlinger representerer en enorm kilde til informasjon som knytter individer fra mange forskjellige arter til et punkt i rom og tid. Dette gjør det mulig å studere og analysere hvordan ulike artsegenskaper ... -
