Structural Aspects of 1,3,5-Benzenetrisamides−A New Family of Nucleating Agents

Structural studies of substituted 1,3,5-benzenetrisamides, a new family of highly versatile and efficient nucleating and clarifying agents for polymeric materials, are reported. Subtle details of the molecular structure of these species are shown to have a ...

Landscape effects on anuran pond occupancy in an agricultural countryside: barrier-based buffers predict distributions better than circular buffers

Rodolphe Schlaepfer, Flavio Zanini, Anna Klingemann

Species movement and occupancy of habitat patches are dependent on landscape permeability. Some land-use types (e.g., roads) may be barriers to animal movement. Analyses of the effect of landscape structure on patch occupancy usually use circular buffers a ...

A landscape genomics approach to understanding and predicting species distribution

Stéphane Joost

In habitat modelling, an initial step is to define geoenvironmental variables to be included in a predictive model. According to Guisan and Zimmermann (2000), the selection of predictors can be made either arbitrarily, automatically by stepwise procedures, ...

Modelling the impact of flooding stress on the growth performance of woody species using fuzzy logic

Rodolphe Schlaepfer

Among the driving processes responsible for riparian forest dynamics the species-specific impact of flooding on the development of woody plants plays a key role-particularly for lowland rivers. Only a few of the forest succession models currently in use in ...

Forcing independent velocity distributions in an experimental granular fluid

Pedro Miguel Nunes Pereira de Almeida Reis

We present experimental results on the velocity statistics of a granular fluid with an effective stochastic thermostat, in a quasi-two-dimensional configuration. We find the base state, as measured by the single particle velocity distribution P(c) in the c ...

Amphibian conservation in human shaped environments

Flavio Zanini

Global biodiversity is experiencing a worrying decline. Habitats destruction, associated to their degradation and fragmentation are among the greatest causes. Amphibians are particularly interesting because they are more threatened and decline more rapidly ...

Transient kinetics of toluene interaction with V/Ti-oxides in anaerobic conditions

Albert Renken, Lioubov Kiwi

Toluene interaction with the catalysts consisting of 0.35, 0.62, 0.75 and 3.7 monolayers (ML) of VOx supported on anatase–titania, containing potassium, was studied by transient response techniques at 523–673 K. FT-Raman spectroscopy under dehydrated condi ...

Statistics of extremes: Modeling ecological disturbances

Marc Parlange

The potential advantage of extreme value theory in modeling ecological disturbances is the central theme of this paper. The statistics of extremes have played only a very limited role in ecological modeling, despite the disproportionate influence of unusua ...

Seasonal dynamics of plant species at fine scale in wooded pastures

Alexandre Buttler, François Gillet, Jean-Michel Gobat

A cell-grid method was used to survey seasonal changes in four herbaceous communities of a wooded pasture. Permanent plots consisted in 1-m3 grids subdivided into 100 cells of 1 dm2. In each cell of each plot and every month from May to September, we estim ...
