Synchrony dynamics of dissolved organic carbon in high-mountain streams: Insights into scale-dependent processes

In high-mountain landscapes, organic carbon (OC) is often limited and heterogeneously stored in poorly developed soils, snow, ground ice, and glaciers. Climate change influences the dynamics of OC mobilization to—and processing into—the recipient streams. ...

Experimental evidence on the impact of climate-induced hydrological and thermal variations on glacier-fed stream biofilms

Tom Ian Battin, Hannes Markus Peter, Grégoire Marie Octave Edouard Michoud, Nicola Deluigi, David Touchette, Martina Gonzalez Mateu

Climate change is predicted to alter the hydrological and thermal regimes of high-mountain streams, particularly glacier-fed streams. However, relatively little is known about how these environmental changes impact the microbial communities in glacier-fed ...

Diversity and biogeography of the bacterial microbiome in glacier-fed streams

Tom Ian Battin, Hannes Markus Peter, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Nicola Deluigi, Matteo Tolosano, Florian Baier, Tyler Joe Kohler, Stylianos Fodelianakis

The rapid melting of mountain glaciers and the vanishing of their streams is emblematic of climate change1,2. Glacier-fed streams (GFSs) are cold, oligotrophic and unstable ecosystems in which life is dominated by microbial biofilms2,3. However, current kn ...

Global 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 ...

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

Tom Ian Battin, Nicola Deluigi, 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 ...

Glacier shrinkage will accelerate downstream decomposition of organic matter and alters microbiome structure and function

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Nicola Deluigi, Matteo Tolosano, Tyler Joe Kohler, Jade Brandani

The shrinking of glaciers is among the most iconic consequences of climate change. Despite this, the downstream consequences for ecosystem processes and related microbiome structure and function remain poorly understood. Here, using a space-for-time substi ...

Assessing the impact of ground ice degradation on high mountain lake environments (Lago Nero catchment, Swiss Alps)

Nicola Deluigi, Monica Bulgheroni

In high mountain hydrosystems, glacial meltwater composition is potentially affected by the degradation of alpine permafrost terrains and ground ice bodies releasing atmospheric pollutants that have been stored in permafrost terrains for several decades. I ...
