We use a long-term precipitation manipulation experiment in mature Pinus sylvestris forests and a natural precipitation gradient from 840 mm to 290 mm/year with Pinus sylvestris var. mongolica, to study the „Drought effects on reproductive phenology and the physiological mechanisms of pine trees“.
al. 2013), or on shifts of reproductive phenology (Mazer et al. 2015) of plants have

WAQUEX – a project on water quality extremes in mountain rivers – investigates the occurrence and drivers of water temperature and sediment load extremes, especially under conditions with increasing droughts, heat waves and floods.
Within this study we tried to understand why and how much rivers have warmed over

The aim of BugNet is to better understand the impact of invertebrate herbivores and fungal pathogens on plant communities and ecosystems. To do so we coordinate surveys on consumers and plant communities, and invertebrate herbivore and fungal exclusion experiments in many part of the world.
Kooperation University of Berne A wide range of organisms attack plants and they have

Detect a „defoliation fingerprint“ in stable isotopes in tree rings.
However, until recently only a few studies have studied hydrogen in tree rings.

The destructive capacity of powder snow avalanche is caused by high-energy pulses within his complex layering. The goal of this project is to understand the origin and nature of the these pulses and quantify the danger they pose to infrastructure.
Field observations at the VdlS have shown two processes closely related to pulse

Europe’s forests are under increasing pressure from climate extremes, requiring better monitoring of changing forest dynamics.
In particulary, I will show how long-term satellite archives have enabled a seamless

This project aims to further develop the Swiss plate geophone system, a passive seismic method to measure bedload transport in water courses, with a new set of controlled experiments and field calibration measurements.
; it has been installed at more than 20 field sites, and direct bedload samples have

This issue relates to a number of fundamental questions in ecology that have challenged

Climate change exacerbates drought-related extremes, with significant ecological, economic, and human health impacts. MaLeFiX project is developing an interdisciplinary platform that will provide comprehensive four-week forecasts of drought-related extremes – buying stakeholders valuable time to act.
Droughts are complex phenomena that have significant implications for many aspects

Ecological and economic systems are complex adaptive systems (CAS): they are systems that are composed of many entities with heterogeneous characteristics, which interact and experience selection processes. Those processes act at the entity level, but are key in determining the macroscopic behaviour at the system level, a feature that make those systems unique.
Analogous economic processes have been proposed to explain differences in economic
