a Drawing scheme of the Burkard Volumetric Spore Sampler describing the parts attached to the main body, with the internal view in detail showing the rotating drum; b Picture of the sampler attached to the tower by a metallic support allowing free rotation according to the wind direction; c Scheme of the steps followed during sampling: (1) sampling tape preparation with adhesive along the entire surface and fixation on the side of the rotating drum, (2) removal of the tape after sampling and separation into pieces, (3) mounting of each piece onto a glass slide, (4) application of coverslip on top, (5) longitudinal scanning under an optical microscope allowing time discrimination (1-h resolution); d example of sampled slide with all the categories: PBA (pollen grain, fungal spore, fern spore, bryophyte spore, yeast, canopy debris) and Other particles. Scale bar: 50 µm.
