Moss spores disperse via wind and have been found previously in precipitation and air samples. Their presence in the atmosphere led to this study’s examining the potential of moss spores to contribute to ice nucleation, a process necessary for ice formation in clouds prior to precipitation. Ice nucleation assays were conducted using Polytrichum commune spores that were either associated with natural assemblages of microbes or extracted aseptically from capsules and subsequently confirmed to be… CONTINUE READING
