Environmental heterogeneity promotes spatial resilience of phototrophic biofilms in streambeds

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

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 ...

Glacier influence shapes the genomic architecture of the downstream aquatic microbiome

Tom Ian Battin, Hannes Markus Peter, Massimo Bourquin, Grégoire Marie Octave Edouard Michoud, Aileen Ute Geers

The factors and processes that shape microbial genomes and determine the success of microbes in different environments have long attracted scientific interest. Here, leveraging 2855 metagenome-assembled genomes (MAGs) sampled by the Vanishing Glacier Proje ...

Centimeter-scale mapping of phototrophic biofilms in glacial forefields using visible band ratios and UAV imagery

Tom Ian Battin, Tyler Joe Kohler

Microbial biofilms have received great attention in the last few decades from both aquatic ecologists and biogeomorphologists. Most recently, this has focused on mapping biofilms to understand their spatial distributions and ecosystem services. Such studie ...

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

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Lorenzo Mari, 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 ...

Alpine Glacier Shrinkage Drives Shift in Dissolved Organic Carbon Export From Quasi‐Chemostasis to Transport Limitation

Tom Ian Battin, Amber Joy Ulseth, Nicolas Thomas Georges Escoffier, Marta Boix Canadell

The export of dissolved organic carbon (DOC) from catchments is considered as an important energy flux through streams and a major connection between terrestrial and aquatic systems. However, the impact that predicted hydrological changes due to glacier re ...

Regimes of primary production and their drivers in Alpine streams

Tom Ian Battin, Amber Joy Ulseth, Marta Boix Canadell, Luis Gómez Gener

Primary production is a fundamental ecosystem process that influences nutrient and carbon cycling, and trophic structure in streams. The magnitude and timing of gross primary production (GPP) are typically controlled by hydrology, light, nutrient availa ...

Substantial decrease in CO2 emissions from Chinese inland waters due to global change

Tom Ian Battin

Carbon dioxide (CO2) evasion from inland waters is an important component of the global carbon cycle. However, it remains unknown how global change affects CO2 emissions over longer time scales. Here, we present seasonal and annual fluxes of CO2 emissions ...

Combining Fluidic Devices with Microscopy and Flow Cytometry to Study Microbial Transport in Porous Media Across Spatial Scales

Tom Ian Battin, David Scheidweiler, Hannes Markus Peter

Understanding the transport, dispersion and deposition of microorganisms in porous media is a complex scientific task comprising topics as diverse as hydrodynamics, ecology and environmental engineering. Modeling bacterial transport in porous environments ...

Biophysical controls on cluster dynamics and architectural differentiation of microbial biofilms in contrasting flow environments

Andrea Rinaldo, Enrico Bertuzzo, Samir Suweis, Lorenzo Mari, Tom Ian Battin

Ecology, with a traditional focus on plants and animals, seeks to understand the mechanisms underlying structure and dynamics of communities. In microbial ecology, the focus is changing from planktonic communities to attached biofilms that dominate microbi ...

Half of global methane emissions come from highly variable aquatic ecosystem sources

Tom Ian Battin

Atmospheric methane is a potent greenhouse gas that plays a major role in controlling the Earth’s climate. The causes of the renewed increase of methane concentration since 2007 are uncertain given the multiple sources and complex biogeochemistry. Here, we ...

Climate-Induced Changes in Spring Snowmelt Impact Ecosystem Metabolism and Carbon Fluxes in an Alpine Stream Network

Enrico Bertuzzo, Tom Ian Battin, Amber Joy Ulseth

Although stream ecosystems are recognized as an important component of the global carbon cycle, the impacts of climate-induced hydrological extremes on carbon fluxes in stream networks remain unclear. Using continuous measurements of ecosystem metabolism, ...

Headwaters are critical reservoirs of microbial diversity for fluvial networks

Enrico Bertuzzo, Tom Ian Battin

Streams and rivers form conspicuous networks on the Earth and are among nature's most effective integrators. Their dendritic structure reaches into the terrestrial landscape and accumulates water and sediment en route from abundant headwater streams to a s ...

Cross-domain interactions confer stability to benthic biofilms in proglacial streams

Leïla Ezzat, Tom Ian Battin, Paraskevi Pramateftaki, Hannes Markus Peter, Jade Brandani, Tyler Joe Kohler, Stylianos Fodelianakis, Massimo Bourquin, Grégoire Marie Octave Edouard Michoud

Cross-domain interactions are an integral part of the success of biofilms in natural environments but remain poorly understood. Here, we describe cross-domain interactions in stream biofilms draining proglacial floodplains in the Swiss Alps. These streams, ...

Deciphering the biosynthetic landscape of biofilms in glacier-fed streams

Leïla Ezzat, Tom Ian Battin, Hannes Markus Peter, Tyler Joe Kohler, Grégoire Marie Octave Edouard Michoud, Aileen Ute Geers

Glacier-fed streams are permanently cold, ultra-oligotrophic, and physically unstable environments, yet microbial life thrives in benthic biofilm communities. Within biofilms, microorganisms rely on secondary metabolites for communication and competition. ...

Automated 3D Optical Coherence Tomography to Elucidate Biofilm Morphogenesis Over Large Spatial Scales

Antoine Wiedmer, Tom Ian Battin, Hannes Markus Peter, Anna Depetris

Biofilms are a most successful microbial lifestyle and prevail in a multitude of environmental and engineered settings. Understanding biofilm morphogenesis, that is the structural diversification of biofilms during community assembly, represents a remarkab ...

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 ...
