Give and take: how much water does soil retain for trees?

Knowledge about plant available soil water is often the missing link to understand large-scale vegetation health observations. This project aims at modelling soil water fluxes with an emphasis on below-ground processes to improve our ability to explain patterns of impacted forest health condition.

Assessing past atmospheric composition in Northern China using novel tree-ring analyses

We aim to assess the presence of particles in trees and to correlate them through dating to known air pollution and sandstorms' episodes.

XELLCLIM

We identify the best xylem cell anatomical features for climate reconstructions and assess their characteristics across temporal scales compared to established tree-ring parameters, and against instrumental records and climate model simulations.

Drought 2018 - TreeNet meets Sentinel2

TreeNet permanently measures growth and tree water deficit (TWD) of about 250 tree individuals in forests all over Switzerland with so-called point dendrometers. TWD has shown to be a reasonable biological indicator for drought stress and quantifies the amount of missing water a tree needs to reach full saturation. In combination with spectral anomalies of satellite-based indices (e.g., NDWI from Sentinel2ab) between 2018 and a reference period we test whether we can find a close link between the two drought stress indicators.

FORClimateS

The project aims to aggregate and synthesize existing information on different spatial and temporal scales to provide decision-makers with relevant and robust information on short- and long-term risks for forests and forest functions and on adaptation strategies under different climate futures

Legacy effects on stem growth

Tree species largely differ in the amount of annual stem growth explained by current-year conditions. Historic conditions have been shown to additionally explain a significant fraction of the unexplained variance. We investigate conceptual and empirical approaches to investigate processes determining stem growth and the respective legacy effects.

Establishing hydrogen isotope analysis of organic material

We aim to develop a method for hydrogen isotope (d2H) analysis of organics which will have many applications in plant and soil sciences and thereby provide a powerful new tool to disentangle and reconstruct past and present physiological, biochemical, and hydrological processes.

Root endophytic fungi and their contribution to arctic and alpine climate change feedback

Arctic and Alpine vegetation dynamics under climate change can exert a lasting impact on belowground processes and ultimately on world's largest carbon stocks. This long-term field manipulation investigates the functional significance of plant interactions with species-specific endophytic fungi.

Environmental impact on wood formation

Wood formation is a process that not only fix carbon into the wood structure, but also determine how much and how safely water can be transported trough the stem of a tree. This project make use of dated tree-rings to investigate how the environment impacts wood formation and structure

Photoperiod and ciracian clocks - effects on adaptation and acclimation

Do evolutionary constraints on photoperiod and circadian clocks hinder adaptation and acclimation of plants to climate change? With this project, we will provide the mechanistic basis and a conceptual framework to understand how climatic and daylight/photoperiod cues jointly affects tree functioning.

Our aim is to estimate Swiss forest net ecosystem productivity (NEP) at monthly or seasonal resolution for each individual year in order to link biomass changes over time with global drivers.

The Swiss long-term monitoring and experimental network

The Swiss Long-term Ecological Network is a set of highly instrumented research platforms (LWF-sites). It is designed to collect, store, manage, analyse and interpret long-term data based on a set of key physical, chemical and biological variables, which drive and respond to environmental changes. Its mission is to improve our understanding of how natural and anthropogenic stresses affect forests and other ecosystems in the long term, and which risks for humans are involved.

Relating the stress and detoxification responses at cell level to the phytotoxic ozone dose in foliage of trees

TEA-Electrical potentials and accoustic emissions of trees

TEA combines established methods in ecophysiology (i.e., measuring sap flow, detecting continuous stem radius changes, and recording the microclimatic conditions) with advanced methods of measuring ultrasonic acoustic emissions (UAEs) and detecting electrophysiological signals, so-called electrical potentials (EPs).

Metalink

Soil contamination with heavy metals is a widespread problem affecting natural, cultivated, urban and industrial sites throughout Europe. The main objective in this Swiss/Polish collaboration project is to characterize the links between environmental, genotypic, and phenotypic features in the metal-tolerant plant model Arabidopsis halleri.

Examining drivers of litter decomposition

Decomposition of plant litter is a key process for the transfer of carbon and nutrients in ecosystems. Carbon contained in the decaying biomass is released to the atmosphere as respired CO2, and may contribute to global warming. Litterbag studies have been used to improve our knowledge of the drivers of litter decomposition, but they lack comparability because litter quality is plant species-specific. The use of commercial tea bags as a standard substrate was suggested in order to harmonize studies, where green tea and rooibos represent more labile and more recalcitrant C compounds as surrogates of local litter.

Der Einbezug von Naturschutzüberlegungen bei der Durchforstung

Impact of fuel wood piles on saproxylic beetles

In Switzerland, a strong increase in the demand for energy wood is expected for the next decades. This is likely to have a strong influence on saproxylic beetles (dependent on dead wood). On the one hand, fewer old trees and less deadwood will remain and decompose in the forest, which directly limits habitat availability for saproxylics. On the other hand, fuel wood exploitation might have indirect ecological consequences.

Dynamics of Forest-Grassland Ecotones

Ecotones are dynamic over-lapping boundary areas where major terrestrial biomes meet. Ecotones are sensitive to climate change and/or human-induced impacts. Environmental changes in ecotones will lead to changes in species composition, biodiversity, structure, functioning, and serves at ecosystem level and regional level.

Antimony uptake as a function of waterlogging in the rhizosphere

Antimony (Sb) is a relatively rare element in the earth's crust, but mining, traffic, waste incineration and an increasing multitude of industrial uses have led to elevated levels in soils and sediments in many locations and consequently increased exposure of plants, animals and humans to this toxic element.

Nadelbäume und Trockenheit

Sehr starke waldbauliche Eingriffe im Gebirgswald können kurzfristig ökonomisch vorteilhaft sein. Langfristig könnten sie aber die Waldverjüngung verzögern und den Holzuwachs vermindern. Ob solche nachteiligen Auswirkungen auftreten und wie gross sie allenfalls sind, wird mit retrospektiven ertragskundlichen und dendroökologischen Erhebungen in Gebirgswäldern abgeschätzt.
