Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

open access: yesOikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

On Concordance Measures for Discrete Data and Dependence Properties of Poisson Model

open access: yesJournal of Probability and Statistics, 2009
We study Kendall's tau and Spearman's rho concordance measures for discrete variables. We mainly provide their best bounds using positive dependence properties. These bounds are difficult to write down explicitly in general.

COBASE: A new copula‐based shuffling method for ensemble weather forecast postprocessing

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We propose COBASE, a novel copula‐based postprocessing methododology that combines the strengths of multivariate parametric correction with non‐parametric rank‐based approaches. We consider two case studies for multi‐site temperature in Austria and multi‐site temperature and dew‐point temperature in the Netherlands.

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

On an Aggregation Theory for Indicators Expressing Behaviors of Complex Systems With an Application to Sustainability

open access: yesSustainable Development, EarlyView.
ABSTRACT Certain attributes of large‐scale complex systems are often expressed through sets of indicators. For example, the sustainability of an entity, be it a nation, a city, an energy system, a corporation etc., can be effectively represented by indicators and corresponding data series.
