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 ...

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

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

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, ...

Glacier-Fed Stream Biofilms Harbor Diverse Resistomes and Biosynthetic Gene Clusters

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

Antimicrobial resistance is an omnipresent phenomenon in the anthropogenically influenced ecosystems. However, its role in shaping microbial community dynamics in pristine environments is relatively unknown. ...

The dark side of the moon: first insights into the microbiome structure and function of one of the last glacier-fed streams in Africa

Tom Ian Battin, Hannes Markus Peter, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Matteo Tolosano, Tyler Joe Kohler, Paraskevi Pramateftaki, Vincent Henri De Staercke, Michail Styllas

The glaciers on Africa's 'Mountains of the Moon' (Rwenzori National Park, Uganda) are predicted to disappear within the next decades owing to climate change. Consequently, the glacier-fed streams (GFSs) that drain them will vanish, along with their residen ...

Spatial patterns of benthic biofilm diversity among streams draining proglacial floodplains

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

Glacier shrinkage opens new proglacial terrain with pronounced environmental gradients along longitudinal and lateral chronosequences. Despite the environmental harshness of the streams that drain glacier forelands, their benthic biofilms can harbor astoni ...

Benthic Biofilms in Glacier-Fed Streams from Scandinavia to the Himalayas Host Distinct Bacterial Communities Compared with the Streamwater

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Matteo Tolosano, Emmy Marie Oppliger, Jade Brandani, Paraskevi Pramateftaki

Microbial life in glacier-fed streams (GFSs) is dominated by benthic biofilms which fulfill critical ecosystem processes. However, it remains unclear how the bacterial communities of these biofilms assemble in stream ecosystems characterized by rapid turno ...

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

Tom Ian Battin, Hannes Markus Peter, Paraskevi Pramateftaki, 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 ...

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 ...

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

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Matteo Tolosano, Tyler Joe Kohler, Stylianos Fodelianakis, Paraskevi Pramateftaki

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 ...

Microdiversity characterizes prevalent phylogenetic clades in the glacier-fed stream microbiome

Tom Ian Battin, Hannes Markus Peter, Massimo Bourquin, Susheel Bhanu Busi, Matteo Tolosano, Jade Brandani, Paraskevi Pramateftaki, Tyler Joe Kohler, Vincent Henri De Staercke, Michail Styllas

Glacier-fed streams (GFSs) are extreme and rapidly vanishing ecosystems, and yet they harbor diverse microbial communities. Although our understanding of the GFS microbiome has recently increased, we do not know which microbial clades are ecologically succ ...
