Currently, a couple of methods are available for pollen counting, such as manual counting, flow cytometry-based and image software-based counting. However, due to inconsistent results and experimental repeatability, a more accurate, consistent, and high-throughput quantification approach is required. This study evaluated and compared the performance between a proposed Swin-transformer-YOLOv5 (S-T-YOLOv5) and common YOLO models in pollen detection and quantification. The present study demonstrated that the S-T-YOLOv5 outperformed other YOLO models, including YOLOv3, YOLOv4, YOLOR, and YOLOv5 for alfalfa (<i>Medicago sativa</i> L.) pollen detection and quantification, with excellent precision (99.6%), recall (99.4%), F<sub>1</sub>-score (0.995), <i>mAP50</i> (99.4%), and <i>mAP50-95</i> (76.2%) values.

Additionally, the S-T-YOLOv5 showed a good transferability in quantifying pollen with varied sizes and shapes in different plant species, including annual fleabane, camelina, Canadian goldenrod, Indian lettuce, mustard, and oilseed rape. In summary, our results showed that the S-T-YOLOv5 is an accurate, robust, and widely adaptable pollen quantification approach, with minimizing errors and labor expense.

Leaf abscission from broadleaved trees and other perennial species can also indicate the status of plant health in response to climate. This happens primarily during autumn in response to seasonal growth conditions and environmental factors, such as changing photoperiod and reduced temperatures. During this period biological material is released in larger quantities to the environment. Here, rural bioaerosol composition during late summer and autumn was captured by MiSEQ sequencing of the rRNA internal transcribed spacer 2 (ITS2) region, a common marker for taxonomic variation. Meteorological parameters were recorded from a proximal weather station. The composition of atmospheric taxa demonstrated that deciduous tree DNA forms part of the bioaerosol community during autumn and, for several common broadleaved tree species, atmospheric DNA abundance correlated to high wind events. This suggests that both flowering and autumn storms cause bioaerosols from deciduous trees that can be detected with eDNA approaches.
