Centimeter-scale mapping of phototrophic biofilms in glacial forefields using visible band ratios and UAV imagery

Tom Ian Battin, Tyler Joe Kohler

Microbial biofilms have received great attention in the last few decades from both aquatic ecologists and biogeomorphologists. Most recently, this has focused on mapping biofilms to understand their spatial distributions and ecosystem services. Such studie ...

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

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

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, ...

Deciphering the biosynthetic landscape of biofilms in glacier-fed streams

Leïla Ezzat, Tom Ian Battin, Hannes Markus Peter, Tyler Joe Kohler, Grégoire Marie Octave Edouard Michoud, Aileen Ute Geers

Glacier-fed streams are permanently cold, ultra-oligotrophic, and physically unstable environments, yet microbial life thrives in benthic biofilm communities. Within biofilms, microorganisms rely on secondary metabolites for communication and competition. ...

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

Nicola Deluigi, 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, Grégoire Marie Octave Edouard Michoud, Florian Baier, Aileen Ute Geers

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

Nicola Deluigi, Tom Ian Battin, Hannes Markus Peter, Michail Styllas, Tyler Joe Kohler, Massimo Bourquin

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 ...

A re-investigation of lake sediment diatoms from the Vestfold Hills, Antarctica, using an updated, fine-grained taxonomy

Tyler Joe Kohler

The non-marine diatom flora of the Antarctic continent is currently being revised as recent work within the Maritime and Sub-Antarctic regions has unveiled a number of new endemic species. The under reporting of endemic species is partially due to the hist ...

Patterns in Microbial Assemblages Exported From the Meltwater of Arctic and Sub-Arctic Glaciers

Tyler Joe Kohler

Meltwater streams connect the glacial cryosphere with downstream ecosystems. Dissolved and particulate matter exported from glacial ecosystems originates from contrasting supraglacial and subglacial environments, and exported microbial cells have the poten ...

Data set of dissolved major and trace elements from the lacustrine systems of Clearwater Mesa, Antarctica

Tyler Joe Kohler

This article presents analytical observations on physicochemical parameters and major and trace element concentrations of water, ice, and sediment samples from the lake systems of Clearwater Mesa (CWM), northeast Antarctic Peninsula. Geo-chemical analyses ...

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

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

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 ...

From the Heroic Age to today: What diatoms from Shackleton's Nimrod expedition can tell us about the ecological trajectory of Antarctic ponds

Tyler Joe Kohler

Biological invasion and environmental change pose major threats to ecosystems. While long-term ecological change is commonly evaluated through sediment cores in lakes, it is generally not feasible for smaller ponds, and spatial resolution is limited. Here, ...

Unexpected functional diversity of stream biofilms within and across proglacial floodplains despite close spatial proximity

Tom Ian Battin, Hannes Markus Peter, Jade Brandani, Tyler Joe Kohler, Grégoire Marie Octave Edouard Michoud

High-mountain streams are particularly vulnerable to climate change because they intimately interface with the cryosphere. As glaciers shrink and snowpack diminishes, proglacial streams will eventually shift from being glacier-fed to streams fed by groundw ...

Glacial ecosystems are essential to understanding biodiversity responses to glacier retreat

Predicting climate-change impacts on the global glacier-fed stream microbiome

Vincent Henri De Staercke, Tom Ian Battin, Hannes Markus Peter, Matteo Tolosano, Tyler Joe Kohler, Stylianos Fodelianakis, Massimo Bourquin, Grégoire Marie Octave Edouard Michoud, Andrew Lean Robison, Aileen Ute Geers

The shrinkage of glaciers and the vanishing of glacier-fed streams (GFSs) are emblematic of climate change. However, forecasts of how GFS microbiome structure and function will change under projected climate change scenarios are lacking. Combining 2,333 pr ...
