Generalized receptor law governs phototaxis in the phytoplankton Euglena gracilis

Andrea Rinaldo, Amos Maritan, Andrea Giometto, Florian Altermatt

Phototaxis, the process through which motile organisms direct their swimming toward or away from light, is implicated in key ecological phenomena (including algal blooms and diel vertical migration) that shape the distribution, diversity, and productivity ...

Using Heat as a Tracer to Characterize Streambed Water Fluxes of the Brenta River (Italy)

Andrea Rinaldo

This work deals with the characterization of the spatial and temporal variability of water exchange fluxes from/to the Brenta river streambed (Veneto, Italy), critically important to regional water resources management. The aquifer system is structurally q ...

Resilience and reactivity of global food security

Andrea Rinaldo, Samir Suweis, Paolo d'Odorico, Amos Maritan

The escalating food demand by a growing and increasingly affluent global population is placing unprecedented pressure on the limited land and water resources of the planet, underpinning concerns over global food security and its sensitivity to shocks arisi ...

Point rainfall statistics for ecohydrological analyses derived from satellite integrated rainfall measurements

Andrea Rinaldo

Satellite rainfall measurements, nowadays commonly available, provide valuable information about the spatial structure of rainfall. In areas with low-density rain gage networks, or where these networks are nonexistent, satellite rainfall measurements can a ...

Experimental evidence for strong stabilizing forces at high functional diversity of aquatic microbial communities

Andrea Rinaldo, Francesco Carrara, Andrea Giometto, Florian Altermatt

Unveiling the mechanisms that promote coexistence in biological communities is a fundamental problem in ecology. Stable coexistence of many species is commonly observed in natural communities. Most of these natural communities, however, are composed of spe ...

Modeling chloride transport using travel time distributions at Plynlimon, Wales

Andrea Rinaldo, Gianluca Botter, Paolo Benettin

Here we present a theoretical interpretation of high-frequency, high-quality tracer time series from the Hafren catchment at Plynlimon in mid-Wales. We make use of the formulation of transport by travel time distributions to model chloride transport origin ...

Floquet theory for seasonal environmental forcing of spatially explicit waterborne epidemics

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

The transmission of waterborne pathogens is a complex process that is heavily linked to the spatial characteristics of the underlying environmental matrix as well as to the temporal variability of the relevant hydroclimatological drivers. In this work, we ...

Complex Interaction of Dendritic Connectivity and Hierarchical Patch Size on Biodiversity in River-Like Landscapes

Andrea Rinaldo, Francesco Carrara, Andrea Giometto, Florian Altermatt

Habitat fragmentation and land use changes are causing major biodiversity losses. Connectivity of the landscape or environmental conditions alone can shape biodiversity patterns. In nature, however, local habitat characteristics are often intrinsically lin ...

Fluvial network organization imprints on microbial co-occurrence networks

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Tom Ian Battin

Recent studies highlight linkages among the architecture of ecological networks, their persistence facing environmental disturbance, and the related patterns of biodiversity. A hitherto unresolved question is whether the structure of the landscape inhabite ...

Metapopulation persistence and species spread in river networks

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

River networks define ecological corridors characterised by unidirectional streamflow, which may impose downstream drift to aquatic organisms or affect their movement. Animals and plants manage to persist in riverine ecosystems, though, which in fact harbo ...

Form, function, and evolution of living organisms

Andrea Rinaldo, Amos Maritan

Despite the vast diversity of sizes and shapes of living organisms, life's organization across scales exhibits remarkable commonalities, most notably through the approximate validity of Kleiber's law, the power law scaling of metabolic rates with the mass ...

Hydrologic controls on basin- scale distribution of benthic invertebrates

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Tom Ian Battin

Streamflow variability is a major determinant of basin-scale distributions of benthic invertebrates. Here we present a novel procedure based on a probabilistic approach aiming at a spatially explicit quantitative assessment of benthic invertebrate abundanc ...

SEHR-ECHO v1.0: a Spatially Explicit Hydrologic Response model for ecohydrologic applications

Bettina Schaefli, Cédric Imfeld, Andrea Rinaldo, Enrico Bertuzzo, Ludovico Nicotina, Pierfrancesco Da Ronco

This paper presents the Spatially Explicit Hydrologic Response (SEHR) model developed at the Laboratory of Ecohydrology of the Ecole Polytechnique Fédérale de Lausanne for the simulation of hydrological processes at the catchment scale. The key concept of ...

Evolution and selection of river networks: Statics, dynamics, and complexity

Andrea Rinaldo, Amos Maritan

Moving from the exact result that drainage network configurations minimizing total energy dissipation are stationary solutions of the general equation describing landscape evolution, we review the static properties and the dynamic origins of the scale-inva ...

Cholera in the Lake Kivu region (DRC): Integrating remote sensing and spatially explicit epidemiological modeling

Flavio Finger, Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto, Allyn Christine Knox

Mathematical models of cholera dynamics can not only help in identifying environmental drivers and processes that influence disease transmission, but may also represent valuable tools for the prediction of the epidemiological patterns in time and space as ...

Optimizing a remotely sensed proxy for plankton biomass in Lake Kivu

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Allyn Christine Knox

Many regions of the world, including inland lakes, present with suboptimal conditions for the remotely sensed retrieval of optical signals, thus challenging the limits of available satellite data-processing tools, such as atmospheric correction models (ACM ...

Glucose- but Not Rice-Based Oral Rehydration Therapy Enhances the Production of Virulence Determinants in the Human Pathogen Vibrio cholerae

Flavio Finger, Andrea Rinaldo, Enrico Bertuzzo, Melanie Blokesch, Marino Gatto, Juliane Kühn

Despite major attempts to prevent cholera transmission, millions of people worldwide still must address this devastating disease. Cholera research has so far mainly focused on the causative agent, the bacterium Vibrio cholerae, or on disease treatment, but ...

Light and hydrologic variability as drivers of stream biofilm dynamics in a flume experiment

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Lorenzo Mari, Marino Gatto, Gianluca Botter, Tom Ian Battin

We run a comparative study of the results of flume experiments and several dynamic models reproducing the effects of streamflow variability on biofilm (i.e. periphyton) temporal dynamics. During the experiment, two contrasting flow regimes, characterised b ...

Spatial characterization of catchment dispersion mechanisms in an urban context

Florian Rossel, Andrea Rinaldo

Previous studies have examined in-depth the dispersion mechanisms in natural catchments. In contrast, these dispersion mechanisms have been studied little in urban catchments, where artificial transport elements and morphological arrangements are expected ...
