Theoretical advances and short-term experimental studies have furthered our understanding of how ecosystems respond to perturbation. However, there are few wellreplicated experimental studies that allow an assessment of long-term responses. Results from a ...
Wood-pastures are semi-natural, highly biodiverse systems maintained by traditional extensive agriculture. They are used for grazing and timber. The shifting mosaics of grassland, shrub thickets and woodland patches in these systems are driven by large her ...
Question: What is the effect of gap size on the seedling emergence, growth and survival of four common tree species in wooded pastures? Location: A pasture in the Jura mountains, Switzerland. Methods: Seeds were sown in a complete three-way factorial desig ...
Traditionally managed mountain grasslands in the Alps are species-rich ecosystems that developed during centuries of livestock grazing. However, changes in land use including fertilisation of well accessible pastures and gradual abandonment of remote sites ...
Animal dispersal in a fragmented landscape depends on the complex interaction between landscape structure and animal behavior. To better understand how individuals disperse, it is important to explicitly represent the properties of organisms and the landsc ...
Dispersal barriers and corridors between habitat patches can strongly affect colonization processes, and therefore patch occupation probability. However, most metapopulation dynamic models assume that heterogeneity in the landscape between patches can be n ...
Connectivity among demes in a metapopulation depends on both the landscape's and the focal organism's properties (including its mobility and cognitive abilities). Using individual-based simulations, we contrast the consequences of three different cognitive ...
In its natural framework, genetic information is embedded within a geographic context. Plants and animals are directly influenced by the specific characteristics of their surrounding environment. Therefore, spatial information is a potentially important el ...
Transient response and temperature-programmed desorption/reaction (TPD/TPR) methods were used to study the formation of adsorbed NOx from N2O and its effect during N2O decomposition to O2 and N2 over FeZSM-5 catalysts at temperatures below 653 K. The react ...
Interaction of N2O at low temps. (473-603 K) with Fe-ZSM-5 zeolites (Fe, 0.01-2.1 wt%) activated by steaming and/or thermal treatment in He at 1323 K was studied by the transient response method and temp.-programmed desorption (TPD). Diffuse reflectance IR ...
