Abstract

Considering their potential implications for human health, agricultural productivity, and ecosystem stability, surprisingly little is known about the composition or dynamics of the atmosphere's biological aerosols. The few studies that have examined phylogenetic diversity in China focused on a single sampling period, whereas this study spans 3 months and includes over 300 samples. The 300+ samples were categorized by month and direction of their back-trajectory. DNA extraction was carried out on the pooled samples in a quantitative manner to allow for comparison between the amount of extracted material and the amount of initial total aerosol mass. Within an individual month, samples originating from similar land types and approximately equidistant to the sampling location exhibited similar diversity, whereas samples originating from much greater distances and from different land types included phyla unique to that location. Phyla from the same origin also varied from one month to the next. The biological diversity found from the Phylochips reinforces the hypothesis that air samples carry a biological record of their history.
