Light availability impacts structure and function of phototrophic stream biofilms across domains and trophic levels

Phototrophic biofilms are ubiquitous in freshwater and marine environments where they are critical for biogeochemical cycling, food webs and in industrial applications. In streams, phototrophic biofilms dominate benthic microbial life and harbour an immens ...

Catchment land cover influences macroinvertebrate food-web structure and energy flow pathways in mountain streams

Tom Ian Battin

Understanding how different food resources sustain stream food webs is fundamental towards increasing our knowledge on trophic structure and energy flow pathways in fluvial ecosystems. 2. Food webs in small mountain streams are sustained by autochthonou ...

Glacier loss and vegetation expansion alter organic and inorganic carbon dynamics in high-mountain streams

Nicola Deluigi, Tom Ian Battin, Camille Aude Rolland, Andrew Lean Robison

High-mountain ecosystems are experiencing the acute effects of climate change, most visibly through glacier recession and the greening of theterrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic ...

Patterns and Drivers of Extracellular Enzyme Activity in New Zealand Glacier-Fed Streams

Vincent Henri De Staercke, Tom Ian Battin, Paraskevi Pramateftaki, Hannes Markus Peter, Matteo Tolosano, Michail Styllas, Tyler Joe Kohler, Stylianos Fodelianakis, Martina Andrea Schön, Susheel Bhanu Busi

Glacier-fed streams (GFSs) exhibit near-freezing temperatures, variable flows, and often high turbidities. Currently, the rapid shrinkage of mountain glaciers is altering the delivery of meltwater, solutes, and particulate matter to GFSs, with unknown cons ...

Modeling the coupled dynamics of stream metabolism and microbial biomass

Enrico Bertuzzo, Tom Ian Battin, Pier Luigi Segatto

Estimating and interpreting ecosystem metabolism remains an important challenge in stream ecology. Here, we propose a novel approach to model, estimate, and predict multiseasonal patterns of stream metabolism (gross primary production [GPP] and ecosystem r ...

Genomic and metabolic adaptations of biofilms to ecological windows of opportunity in glacier-fed streams

Leïla Ezzat, Vincent Henri De Staercke, Tom Ian Battin, Paraskevi Pramateftaki, Hannes Markus Peter, Matteo Tolosano, Michail Styllas, Tyler Joe Kohler, Stylianos Fodelianakis, Massimo Bourquin, Martina Andrea Schön, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud

In glacier-fed streams, ecological windows of opportunity allow complex microbial biofilms to develop and transiently form the basis of the food web, thereby controlling key ecosystem processes. Using metagenome-assembled genomes, we unravel strategies tha ...

Widespread Black Carbon Deposition of Varied Origin Exported From Glaciers

Tom Ian Battin, Hannes Markus Peter

Atmospheric deposition delivers carbon to glacier surfaces, including from fossil fuel and biomass combustion. Nonetheless, spatial variation in the sources of organic and black carbon deposited on glaciers is poorly understood, along with their role in dr ...

Morphogenesis and oxygen dynamics in phototrophic biofilms growing across a gradient of hydraulic conditions

Amin Niayifar, Tom Ian Battin, Hannes Markus Peter, Anna Depetris

Biofilms are surface-attached and matrix-enclosed microbial communities that dominate microbial life in numerous ecosystems. Using flumes and automated optical coherence tomography, we studied the morphogenesis of phototrophic biofilms along a gradient of ...

Viral diversity is linked to bacterial community composition in alpine stream biofilms

Tom Ian Battin, Paraskevi Pramateftaki, Hannes Markus Peter, Meriem Bekliz

Biofilms play pivotal roles in fluvial ecosystems, yet virtually nothing is known about viruses in these communities. Leveraging an optimized sample-to-sequence pipeline, we studied the spatiotemporal turnover of dsDNA viruses associated with stream biofil ...

Ecosystem engineering by periphyton in Alpine proglacial streams

Tom Ian Battin, Davide Mancini

Stream periphytons are candidate ecosystem engineers in proglacial margins. Here, we quantify the extent to which they are engineers for the case of hillslope-fed tributaries in the terrace zones of proglacial margin alluvial plains. Candidate ecosystem en ...

Travel Time and Source Variation Explain the Molecular Transformation of Dissolved Organic Matter in an Alpine Stream Network

Tom Ian Battin, Amber Joy Ulseth, Hannes Markus Peter

Streams and rivers are important components of the carbon cycle as they transport and transform dissolved organic matter (DOM). Using high resolution Fourier transform ion cyclotron resonance mass spectrometry, we studied the spatial distribution of DOM at ...

Gradients of Deposition and In Situ Production Drive Global Glacier Organic Matter Composition

Vincent Henri De Staercke, Tom Ian Battin, Hannes Markus Peter, Matteo Tolosano, Michail Styllas, Martina Andrea Schön

Runoff from rapidly melting mountain glaciers is a dominant source of riverine organic carbon in many high-latitude and high-elevation regions. Glacier dissolved organic carbon is highly bioavailable, and its composition likely reflects internal (e.g., aut ...

Preferential retention of algal carbon in benthic invertebrates: Stable isotope and fatty acid evidence from an outdoor flume experiment

Tom Ian Battin

According to the River Continuum Concept, headwater streams are richer in allochthonous (e.g. terrestrial leaves) than autochthonous (e.g. algae) sources of organic matter for consumers. However, compared to algae, leaf litter is of lower food quality, par ...
