Kumar N, Grogan P, Chu H, Christiansen C, Walker V. The effect of freeze-thaw conditions on arctic soil bacterial communities. Biology (Basel). 2013;2:356-77 pubmed publisher
..This perspectives article suggests that this is an unwelcome finding since it will make future predictions for the impact of on-going climate change on soil microbial communities in arctic regions all but impossible. ..
Tomalty H, Walker V. Perturbation of bacterial ice nucleation activity by a grass antifreeze protein. Biochem Biophys Res Commun. 2014;452:636-41 pubmed publisher
..Thus, we postulate that in addition to controlling ice growth, plant AFPs may also function as a defensive strategy against the damaging effects of ice-nucleating bacteria. ..
