Rosemary Eufemio (Ph.D. Student) recently published in Biogeosciences, a journal that is a part of the European Geosciences Union. Her publication, Lichen species across Alaska produce highly active and stable ice nucleators, found that ice nucleating activity in lichens are widespread, particularly in the coastal rainforest of southeast Alaska. She found that lichens contain two subpopulations of biological ice nucleators, which are similar to observations in bacteria. The ubiquity and high stability of the lichen ice nucleators suggest that they can impact local atmospheric processes and that ice nucleation activity is an essential trait for their survival in cold environments.
