Possible interactions between bacterial diversity, microbial activity and supraglacial hydrology of cryoconite holes in Svalbard

Arwyn Edwards, Alexandre M Anesio, +5 authors Gareth W. Griffith
The ISME Journal
2011

The diversity of highly active bacterial communities in cryoconite holes on three Arctic glaciers in Svalbard was investigated using terminal restriction fragment length polymorphism (T-RFLP) of the… (More)

Community analysis of the bacterial assemblages in the winter cover and pelagic layers of a high mountain lake by in situ hybridization.

Albin Alfreider, Jakob Pernthaler, +4 authors Roland Psenner
Applied and environmental microbiology
1996

The bacterial community structure in the winter cover and pelagic zone of a high mountain lake was analyzed by in situ hybridization with fluorescently labeled rRNA-targeted oligonucleotide probes.… (More)

Factors influencing bacterial dynamics along a transect from supraglacial runoff to proglacial lakes of a high Arctic glacier [corrected].

Birgit Mindl, Alexandre M Anesio, +4 authors Birgit Sattler
FEMS microbiology ecology
2007

Bacterial production in glacial runoff and aquatic habitats along a c. 500 m transect from the ablation area of a Svalbard glacier (Midre Lovénbreen, 79 degrees N, 12 degrees E) down to a series of… (More)

Coupled cryoconite ecosystem structure-function relationships are revealed by comparing bacterial communities in alpine and Arctic glaciers.

Arwyn Edwards, Luis A J Mur, +11 authors Birgit Sattler
FEMS microbiology ecology
2014

Cryoconite holes are known as foci of microbial diversity and activity on polar glacier surfaces, but are virtually unexplored microbial habitats in alpine regions. In addition, whether cryoconite… (More)

A metagenomic snapshot of taxonomic and functional diversity in an alpine glacier cryoconite ecosystem

Arwyn Edwards, Justin A. Pachebat, +5 authors Birgit Sattler
2013

Cryoconite is a microbe–mineral aggregate which darkens the ice surface of glaciers. Microbial process and marker gene PCR-dependent measurements reveal active and diverse cryoconite microbial… (More)

Phylogenetic and functional heterogeneity of sediment biofilms along environmental gradients in a glacial stream.

Tom J. Battin, Anton Wille, Birgit Sattler, Roland Psenner
Applied and environmental microbiology
2001

We used in situ hybridization with fluorescently labeled rRNA-targeted oligonucleotide probes concurrently with measurements of bacterial carbon production, biomass, and extracellular polymeric… (More)

Metabolic activity and diversity of cryoconites in the Taylor Valley , Antarctica

[1] Metabolic activity and biogeochemical diversity within cryoconites from the Canada, Commonwealth, Howard, and Hughes glaciers in the McMurdo Dry Valleys revealed the presence of a productive… (More)

Microorganisms in the atmosphere over Antarctica.

David A. Pearce, Paul D. Bridge, Kevin A. Hughes, Birgit Sattler, Roland Psenner, Nick J. Russell
FEMS microbiology ecology
2009

Antarctic microbial biodiversity is the result of a balance between evolution, extinction and colonization, and so it is not possible to gain a full understanding of the microbial biodiversity of a… (More)

The dynamic bacterial communities of a melting High Arctic glacier snowpack

Katherina Hell, Arwyn Edwards, +5 authors Birgit Sattler
The ISME Journal
2013

Snow environments can occupy over a third of land surface area, but little is known about the dynamics of snowpack bacteria. The effect of snow melt on bacterial community structure and diversity of… (More)

Carbon fluxes through bacterial communities on glacier surfaces

Alexandre M Anesio, Birgit Sattler, +4 authors Roland Psenner
2010

There is very little information about the activity of microbial communities on the surface of glaciers, though there is an increasing body of evidence to show that they strongly influence the… (More)
