Bak F, Keuschnig C, Nybroe O, Aamand J, Jorgensen P, Nicolaisen M, et al.
BMC Microbiol . 2024 Aug; 24(1):296. PMID: 39123130
Background: Subsurface microorganisms contribute to important ecosystem services, yet little is known about how the composition of these communities is affected by small scale heterogeneity such as in preferential flow...

Sanchez-Cid C, Guironnet A, Keuschnig C, Wiest L, Vulliet E, Vogel T
ISME Commun . 2023 Nov; 2(1):29. PMID: 37938295
Antibiotics released into the environment at low (sub-inhibitory) concentrations could select for antibiotic resistance that might disseminate to the human microbiome. In this case, low-level anthropogenic sources of antibiotics would...

Sanchez-Cid C, Keuschnig C, Vogel T, Larose C
FEMS Microbiol Ecol . 2023 Apr; 99(6). PMID: 37073121
Polar regions are increasingly exposed to ultraviolet light due to ozone depletion. Snowpacks contain photochemically active particles that, when irradiated, can lead to the production and accumulation of reactive species...

Keuschnig C, Vogel T, Barbaro E, Spolaor A, Koziol K, Bjorkman M, et al.
Microbiome . 2023 Mar; 11(1):35. PMID: 36864462
Background: Arctic snowpack microbial communities are continually subject to dynamic chemical and microbial input from the atmosphere. As such, the factors that contribute to structuring their microbial communities are complex...

Bradley J, Trivedi C, Winkel M, Mourot R, Lutz S, Larose C, et al.
Geobiology . 2022 Nov; 21(2):244-261. PMID: 36450703
Glacier and ice sheet surfaces host diverse communities of microorganisms whose activity (or inactivity) influences biogeochemical cycles and ice melting. Supraglacial microbes endure various environmental extremes including resource scarcity, frequent...
6.
Sanchez-Cid C, Keuschnig C, Torzewski K, Stachnik L, Kepski D, Luks B, et al.
Front Microbiol . 2022 Jul; 13:918622. PMID: 35783390
Winter tourism can generate environmental pollution and affect microbial ecology in mountain ecosystems. This could stimulate the development of antibiotic resistance in snow and its dissemination through the atmosphere and...

Trivedi C, Keuschnig C, Larose C, Rissi D, Mourot R, Bradley J, et al.
Front Microbiol . 2022 Jun; 13:894893. PMID: 35677909
The preservation of nucleic acids for high-throughput sequencing is an ongoing challenge for field scientists. In particular, samples that are low biomass, or that have to be collected and preserved...

Keuschnig C, Larose C, Rudner M, Pesqueda A, Doleac S, Elberling B, et al.
Glob Chang Biol . 2022 Mar; 28(10):3411-3425. PMID: 35285570
In Arctic regions, thawing permafrost soils are projected to release 50 to 250 Gt of carbon by 2100. This data is mostly derived from carbon-rich wetlands, although 71% of this...

Klarenberg I, Keuschnig C, Russi Colmenares A, Warshan D, Jungblut A, Jonsdottir I, et al.
New Phytol . 2021 Nov; 234(6):2044-2056. PMID: 34719786
Bacterial communities form the basis of biogeochemical processes and determine plant growth and health. Mosses harbour diverse bacterial communities that are involved in nitrogen fixation and carbon cycling. Global climate...

Klarenberg I, Keuschnig C, Warshan D, Jonsdottir I, Vilhelmsson O
Front Microbiol . 2021 Jan; 11:540404. PMID: 33391192
Lichens are traditionally defined as a symbiosis between a fungus and a green alga and or a cyanobacterium. This idea has been challenged by the discovery of bacterial communities inhabiting...
