Natkon Dendrometer auf 3SAT!

Natkon Dendrometer auf 3SAT!

Im Rahmen der Wissenschaftssendung Nano auf 3SAT, wird auch einer unserer Dendrometer (ZN11-O-WP) prominent in Szene gesetzt. In der Reportage der ‘Gesang der Bäume’ stellen Marcus Maeder (ZHdK) und Roman Zweifel (WSL/Natkon) das SNF-Projekt ‘trees – ökophysiologische Prozesse hörbar machen‘ vor. Darin wird gezeigt, dass…

Klanginstallation an der WSL – trees: Pinus sylvestris

Klanginstallation an der WSL – trees: Pinus sylvestris

Im Rahmen des SNF-Forschungsprojekts ‘trees – Ökophysiologische Prozesse hörbar machen’ beherbergt die WSL Birmensdorf das Exponat ‘trees – Pinus sylvestris‘. Ultraschallsignale aus Ästen werden parallel zu sonifizierten Ökophysiologie-Daten hörbar gemacht. Kamera-Bilder der gemessenen Äste nach Osten und Westen komplementieren die audiovisuelle Erfahrung. Das Projekt ist…

Publication in Biogeosciences: Previous-year weather determines forest NEP

Publication in Biogeosciences: Previous-year weather determines forest NEP

Abstract. Understanding the response of forest net ecosystem productivity (NEP) to environmental drivers under climate change is highly relevant for predictions of annual forest carbon (C) flux budgets. Modeling annual forest NEP with soil–vegetation–atmosphere transfer models (SVATs), however, remains challenging due to unknown delayed responses…

Publication in New Phytologist: CO2-effect on stem radius fluctuations

Publication in New Phytologist: CO2-effect on stem radius fluctuations

To understand how trees at high elevations might use water differently in the future, we investigated the effects of CO2 enrichment and soil warming (separately and combined) on the water relations of Larix decidua growing at the tree line in the Swiss Alps. We assessed…

Publication in Functional Plant Biology: Xylem size changes

Abstract. The state-of-the-art interpretation of stem radius changes (DRTotal) for tree water relations is based on knowledge from mostly slow growing tree species. The ratio between diurnal size fluctuations of the rigid xylem (DRXylem) and the respective fluctuations of the elastic bark (DRBark) is known…
