Living particulate fluxes in throughfall and stemflow during a pollen event

Pollen shedding can produce rapid, abundant exchanges of nutrient-rich biomass from plant canopies to the surface. When pollen deposits onto understory plants, it be washed off during storms via throughfall (a drip flux) and stemflow flux down stems). deposition may also alter organismal community on surfaces, changing other biological particulates transported by stemflow. We report concentrations fluxes (flagellate cells, nematodes, rotifers, mites hexapodans) in an forb, Eupatorium capillifolium (Lam. dogfennel), a Pinus palustris (Mill. longleaf pine) event, then compare these results observations collected when was absent. 95.6 × 106 grains ha−1 season−1 dogfennel (63% 37% stemflow, respectively), representing 0.1–3.2 g ha−1. Median flagellates, nematodes rotifers for were higher shedding; however, hexapodan similar regardless presence. This is first flagellate canopy drainage waters. Flagellate than organisms—being those reported streams, 105–107 cells L−1—and ~ 50 individuals m−2 per 1 cm rainfall. These indicate that (i) transport ecologically relevant amounts organisms phyllosphere surface, (ii) composition change markedly shedding.
