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

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

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 ...

Global carbon dioxide efflux from rivers enhanced by high nocturnal emissions

Tom Ian Battin, Hannes Markus Peter, Asa Lovisa Viktoria Horgby, Luis Gómez Gener

Carbon dioxide (CO2) emissions to the atmosphere from running waters are estimated to be four times greater than the total carbon (C) flux to the oceans. However, these fluxes remain poorly constrained because of substantial spatial and temporal variabilit ...

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 ...

Hydrology controls the carbon mass balance of a mountain lake in the eastern European Alps

Tom Ian Battin

Lakes and streams in mountain regions are important contributors to carbon (C) fluxes. However, detailed carbon balances of the stream‐lake continuum are rare. Combining eddy covariance (EC) measurements of lake‐atmosphere net ecosystem CO2 exchange with m ...

Microbial Ecology of Methanotrophy in Streams Along a Gradient of CH4 Availability

Alexandre Bagnoud, Tom Ian Battin, Paraskevi Pramateftaki, Hannes Markus Peter

Despite the recognition of streams and rivers as sources of methane (CH4) to the atmosphere, the role of CH4 oxidation (MOX) in these ecosystems remains poorly understood to date. Here, we measured the kinetics of MOX in stream sediments of 14 sites to res ...

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 ...

Sources, Transformation, and Fate of Dissolved Organic Matter in the Gravel Bar of a Prealpine Stream

Tom Ian Battin

Gravel bars (GBs) are hotspots of biogeochemical activity, likely impacting carbon dynamics instreams and rivers. However, it remains unclear how GBs process dissolved organic matter (DOM) receivedfrom stream water and groundwater. Here we investigate the ...

Optimised biomolecular extraction for metagenomic analysis of microbial biofilms from high-mountain streams

Tom Ian Battin, Paraskevi Pramateftaki, Hannes Markus Peter, Jade Brandani, Stylianos Fodelianakis, Susheel Bhanu Busi

Glacier-fed streams (GFS) are harsh ecosystems dominated by microbial life organized in benthic biofilms, yet the biodiversity and ecosystem functions provided by these communities remain under-appreciated. To better understand the microbial processes and ...

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 ...

Daily entropy of dissolved oxygen reveals different energetic regimes and drivers among high‐mountain stream types

Mélanie Clémençon, Tom Ian Battin, Marta Boix Canadell, Luis Gómez Gener

High‐resolution time series of dissolved oxygen (DO) have revealed different ecosystem energetics regimes across various stream types. Ecosystem energetic regimes are relevant to better understand the transformation and retention of nutrients and carbon in ...

Key rules of life and the fading cryosphere: impacts in alpine lakes and streams

Tom Ian Battin, Chenxi Wu, Jun Wen, Xiong Xiong

Alpine regions are changing rapidly due to loss of snow and ice in response to ongoing climate change. While studies have documented ecological responses in alpine lakes and streams to these changes, our ability to predict such outcomes is limited. We prop ...

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 ...

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 ...

Glacier retreat changes diurnal variation intensity and frequency of hydrologic variables in Alpine and Andean streams

Tom Ian Battin, Nicolas Thomas Georges Escoffier, Asa Lovisa Viktoria Horgby, Marta Boix Canadell

The impacts of glacier mass and area loss are assumed to affect stream hydrology and related ecosystems. We applied wavelet analysis to high frequency time series of discharge, conductivity, turbidity, air and water temperature in mountain streams influenc ...

Trait-specific dispersal of bacteria in heterogeneous porous environments: from pore to porous medium scale

Tom Ian Battin, David Scheidweiler, Hannes Markus Peter, Filippo Miele

The dispersal of organisms controls the structure and dynamics of populations and communities, and can regulate ecosystem functioning. Predicting dispersal patterns across scales is important to understand microbial life in heterogeneous porous environment ...
