Plausible microbial metabolisms on Mars
(2013) - Journal article
Sophie L Nixon, Claire R Cousins and Charles S Cockell explore the possible ways in which any Martian life could get energy.
Emerging biogeochemical views of Earth's ancient microbial worlds
(2015-12-01) - Journal article
Microbial processes dominate geochemical cycles at and near the Earth’s surface today. Their role was even greater in the past, with microbes being the dominant life form for the first 90% of Earth’s history. Most of their ...
Planetary science and exploration in the deep subsurface : results from the MINAR Program, Boulby Mine, UK
(2017-04) - Journal article
The subsurface exploration of other planetary bodies can be used to unravel their geological history and assess their habitability. On Mars in particular, present-day habitable conditions may be restricted to the subsurface. ...
An ESA roadmap for geobiology in space exploration
(2016-01) - Journal article
Geobiology, and in particular mineral-microbe interactions, has a significant role to play in current and future space exploration. This includes the search for biosignatures in extraterrestrial environments, and the human ...
Understanding cold bias: variable response of skeletal Sr/Ca to seawater pCO2 in acclimated massive Porites corals
(2016-05-31) - Journal article
Coral skeletal Sr/Ca is a palaeothermometer commonly used to produce high resolution seasonal sea surface temperature (SST) records and to investigate the amplitude and frequency of ENSO and interdecadal climate events. ...
The Astrobiology Primer v2.0
(2016-08-01) - Journal article
Sulphur cycling in a Neoarchean microbial mat
(2017-05) - Journal article
Multiple sulphur (S) isotope ratios are powerful proxies to understand the complexity of S biogeochemical cycling through Deep Time. The disappearance of a sulphur mass independent fractionation (S-MIF) signal in rocks ...
Public support for conserving bird species runs counter to climate change impacts on their distributions
(2014-07-01) - Journal article
There is increasing evidence that global climate change will alter the spatiotemporal occurrences and abundances of many species at continental scales. This will have implications for efficient conservation of biodiversity. ...
Cyanobacterial endobionts within a major marine planktonic calcifier (Globigerina bulloides, Foraminifera) revealed by 16S rRNA metabarcoding
(2017-02-28) - Journal article
We investigated the possibility of bacterial symbiosis in Globigerina bulloides, a palaeoceanographically important, planktonic foraminifer. This marine protist is commonly used in micropalaeontological investigations of ...
The effects of invasive pests and pathogens on strategies for forest diversification
(2017-04-24) - Journal article
Diversification of the tree species composition of production forests is a frequently advocated strategy to increase resilience to pests and pathogens; however, there is a lack of a general framework to analyse the impact ...
