Epidemicity indices and reproduction numbers from infectious disease data in connected human populations

Andrea Rinaldo, Cristiano Trevisin, Lorenzo Mari, Marino Gatto

We focus on distinctive data-driven measures of the fate of ongoing epidemics. The relevance of our pursuit is suggested by recent results proving that the short-term temporal evolution of infection spread is described by an epidemicity index related to th ...

Spatial and temporal heterogeneity of methane ebullition in lowland headwater streams and the impact on sampling design

Andrew Lean Robison

Headwater streams are known sources of methane (CH4) to the atmosphere, but their contribution to global scale budgets remains poorly constrained. While efforts have been made to better understand diffusive fluxes of CH4 in streams, much less attention has ...

Environmental heterogeneity promotes spatial resilience of phototrophic biofilms in streambeds

Andrea Rinaldo, Tom Ian Battin, Hannes Markus Peter, Enrico Bertuzzo, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez

The loss of environmental heterogeneity threatens biodiversity and ecosystem functioning. It is therefore important to understand the relationship between environmental heterogeneity and spatial resilience as the capacity of ecological communities embedded ...

Field study on drainage densities and rescaled width functions in a high‐altitude alpine catchment

Andrea Rinaldo, Marc Parlange, Raphaël Mutzner

This paper addresses the effect of accurately mapping spatially heterogeneous drainage densities in high-altitude alpine basins on Rescaled Width Functions (RWFs), used in some applications as a minimalist model of the hydrologic response. The channel netw ...

Comparative life cycle assessment of biodiesel from algae and jatropha: A case study of India

Edgard Gnansounou, Jegannathan Kenthorai Raman

Algae and jatropha, two types of promising and unconventional biomass, are investigated in this study for large-scale production of biodiesel. The aim is to evaluate the potential advantages and the magnitude of closeness of life cycle balances between the ...

Spatial Heterogeneity of Methane Ebullition in a Large Tropical Reservoir

Alfred Johny Wüest, Bernhard Wehrli

Tropical reservoirs have been identified as important methane (CH4) sources to the atmosphere, primarily through turbine and downstream degassing. However, the importance of ebullition (gas bubbling) remains unclear. We hypothesized that ebullition is a di ...

Invasion and eradication of a competitively superior species in heterogeneous landscapes

Alexandre Buttler, Séverine Vuilleumier Varisco, Nicolas Perrin

The effect of heterogeneous environments upon the dynamics of invasion and the eradication or control of invasive species is poorly understood, although it is a major challenge for biodiversity conservation. Here, we first investigate how the probability a ...

The geographical dimension of genetic diversity : a GIScience contribution for the conservation of animal genetic resources

Stéphane Joost

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 ...
