Cedrus libani: A promising tree species for Central European forestry facing climate change?

Considering climate change, the discussion intensifies whether and to what extent exotic tree species should be taken into account for forest cultivation, especially when indigenous species are no longer able to fulfill essential forest functions. In this ...

Functional traits as a new approach for interpreting testate amoeba palaeo-records in peatlands and assessing the causes and consequences of past changes in species composition

Edward Mitchell, Vincent Eric Jules Jassey, Enrique Lara, Bertrand Fournier

Subfossil remains of various groups of organisms preserved in peat and sediment archives are commonly used to infer past environmental changes using transfer functions based on species composition. However, the changes in community structure can also be ex ...

Very high resolution digital elevation models: are multi-scale derived variables ecologically relevant?

Stéphane Joost, Kevin Leempoel, Pascal Vittoz

Digital Elevation Models (DEMs) are often used in landscape ecology to retrieve elevation or first derivative terrain attributes such as slope or aspect in the context of species distribution modelling. However, DEM-derived variables are scale-dependent an ...

Distinct invasion strategies operating within a natural annual plant system

Thomas Spiegelberger, Justine Marie Gay des Combes

Alien plant species are known to have a wide range of impacts on recipient communities, from resident species' exclusions to coexistence with resident species. It remains unclear; however, if this variety of impacts is due to different invader strategies, ...

Altitudinal patterns of diversity and functional traits of metabolically active microorganisms in stream biofilms

Tom Ian Battin, Hannes Markus Peter

Resources structure ecological communities and potentially link biodiversity to energy flow. It is commonly believed that functional traits (generalists versus specialists) involved in the exploitation of resources depend on resource availability and envir ...

Phytoremediation of polluted soils: hype, hope and facts

Jean-Paul Schwitzguebel

Different plant species, ecotypes, varieties or cultivars can be selected, tailored and harnessed for the remediation of polluted soils, sites and brownfields, as well as for the phytotreatment of domestic or industrial wastewater. Several approaches are p ...

Contributions to Spatial Statistics

Emeric Rolland Georges Thibaud

This thesis proposes some contributions to the spatial modelling of species distributions and extreme values. Predictive models are increasingly used to model the distribution of species and to estimate the potential effects of global change on biodiversit ...

Plant functional types define magnitude of drought response in peatland CO2 exchange

Luca Bragazza, Bjorn Jozef Maria Robroek

Peatlands are important sinks for atmospheric carbon (C), yet the role of plant functional types (PFTs) for C sequestration under climatic perturbations is still unclear. A plant-removal experiment was used to study the importance of vascular PFTs for the ...

Plant detoxification capacity of xenobiotic compounds as limiting factor for phytoremediation

Jean-Paul Schwitzguebel

Plants have efficient mechanisms for detoxification and sequestration of xenobiotic chemicals and trace elements, basis of any phytoremediation process. However the amount of pollutants that can be accumulated and detoxified without disrupting the primary ...

Invasion by Fallopia spp. in a French upland region is related to anthropogenic disturbances

Thomas Spiegelberger

Within Europe, mountain ecosystems are generally less invaded by exotic plant species than are lowland areas. This pattern is commonly attributed to climatic harshness, which limits invasive species presence, and higher propagule pressure and rates of dist ...
