Environmental drivers of viral community composition in Antarctic soils identified by viromics

Microbiome, 2017
Background The Antarctic continent is considered the coldest and driest place on earth with simple ecosystems, devoid of higher plants. Soils in the ice-free regions of Antarctica are known to harbor a wide range of microorganisms from primary producers ...

Differential Functional Constraints Cause Strain-Level Endemism in Polynucleobacter Populations. [PDF]

, 2016
The adaptation of bacterial lineages to local environmental conditions creates the potential for broader genotypic diversity within a species, which can enable a species to dominate across ecological gradients because of niche flexibility.

A Decade of Plague in Mahajanga, Madagascar: Insights into the Global Maritime Spread of Pandemic Plague

mBio, 2013
A cluster of human plague cases occurred in the seaport city of Mahajanga, Madagascar, from 1991 to 1999 following 62 years with no evidence of plague, which offered insights into plague pathogen dynamics in an urban environment.

Community diversity and habitat structure shape the repertoire of extracellular proteins in bacteria

Nature Communications, 2020
Microbes secrete a repertoire of extracellular proteins to serve various functions depending on the ecological context. Here the authors examine how bacterial community composition and habitat structure affect the extracellular proteins, showing that ...
