Interactivity is a central theme of ecological psychology. According to Gibsonian views,
behavior is the emergent property of interactions between organism and environment …

Ecologists sometimes have a less-than-rigorous background in quantitative methods, yet
research within this broad field is becoming increasingly mathematical. Written in a step-by …

This work deals with a rainfall-discharge model applied to a well known karst aquifer. A new
approach is developed in order to minimize the fitting parameters: here, some of the model …

Oxygen isotope ratios in speleothems may be affected by external processes that are
independent of climate, such as karst hydrology and kinetic fractionation. Consequently …

Calvet and Fisher present a powerful, new technique for volatility forecasting that draws on
insights from the use of multifractals in the natural sciences and mathematics and provides a …

Abstract Multifractal Detrended Fluctuation Analysis (MFDFA) is an efficient method to
investigate the long-term correlations of the power law of non-stationary time series, in which …

A better knowledge of dripwater hydrology in karst systems is needed to understand the
palaeoclimate implications of temporal variations in Mg/Ca and Sr/Ca of calcareous cave …

Matrix permeability in the range of 10− 11 to 10− 14 m2 characterizes eogenetic karst,
where limestones have not been deeply buried. In contrast, limestones of postburial …

The extreme variability of rainfall over huge ranges of space–time scales makes direct rain
gauge measurements of areal rainfall impossible; assumptions about the rainfall scaling …

A rainfall-discharge model is applied to an aquifer characterized by active groundwater
management–the Lez karst aquifer in the South of France. Groundwater is withdrawn by …
