The microbial genomics of glacier-fed streams: adaptations to an extreme ecosystem
Glacier-fed streams are the cold, ultra-oligotrophic, and unstable streams that are fed by glacial meltwater. Despite these extreme conditions, they harbour a diverse and abundant microbial diversity that develops into biofilms, covering the boulders and s ...
EPFL2024Global emergent responses of stream microbial metabolism to glacier shrinkage
Tom Ian Battin, Hannes Markus Peter, Massimo Bourquin, Nicola Deluigi, Tyler Joe Kohler, Michail Styllas
Most cryospheric ecosystems are energy limited. How their energetics will respond to climate change remains largely unknown. This is particularly true for glacier-fed streams, which interface with the cryosphere and initiate some of Earth's largest river s ...
Berlin2024Climatic and Ecological Impact of Greenlandic Glacial Outwash Plains
Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh
Warming in the Arctic is occurring at an accelerated rate compared to the rest of the world which is partially driven by ecological and climatic feedback loops. Accelerated glacial and ice sheet retreat in Greenland drives increased development of glacial ...
2023The biofilm ecology of proglacial floodplain streams
Glacial forelands figure among the most dynamic landscapes on Earth, and their formation is currently accelerating given glacier shrinkage. Draining these forelands are streams hosting unique microbial communities, which have the capacity to impact both th ...
EPFL2023Near-bed stratification controls bottom hypoxia in ice-covered alpine lakes
Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Camille Roland Marie Minaudo, Janine Rüegg, Tomy Doda, Nicolas Thomas Georges Escoffier, Hannah Elisa Chmiel, Pascal Perolo
In ice-covered lakes, near-bottom oxygen concentration decreases for most of the wintertime, sometimes down to the point that bottom waters become hypoxic. Studies insofar have reached divergent conclusions on whether climate change limits or reinforces th ...
WILEY2023The dark side of the moon: A glimpse into the future of the microbiome structure and function of glacier-fed streams
Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Tyler Joe Kohler
Glaciers are receding at an unprecedented rate with expected losses of up to half their masses by 2100. Such changes will have a profound effect on the physicochemical characteristics of glacier-fed stream (GFS) water, such as the composition of organic ma ...
2023Ecosystem engineering by periphyton in Alpine proglacial streams
Tom Ian Battin, Davide Mancini, Marc Aguet, Adrijan Selitaj, Matteo Roncoroni
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 ...
WILEY2023Glacier retreat and increasing vegetation cover alter the sources and sinks of organic and inorganic carbon in alpine streams
Nicola Deluigi, Andrew Lean Robison
High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the greening of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, g ...
2023Iron Reduction in Profundal Sediments of Ultraoligotrophic Lake Tahoe under Oxygen-Limited Conditions
Increased periods of bottom water anoxia in deep temperate lakes due to decreasing frequency and depth of water column mixing in a warming climate may result in the reductive dissolution of iron minerals and increased flux of nutrients from the sediment in ...
2023Glacier loss and vegetation expansion alters organic and inorganic carbon dynamics in alpine streams
Tom Ian Battin, Nicola Deluigi, Andrew Lean Robison, Camille Aude Rolland
High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the ‘greening’ of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, ...
