“…Third, surfaces of leaf, twig and trunk provide habitats for a wide of organisms including bacteria, fungi, algae and lichens. Forests have been shown to host a diversity of epiphyllic microorganisms and florae (Farkas & Sipman, 1993; Søchting, 1997), which may be a sink of gaseous N (Bäck et al., 1997). These organisms may be washed off from the canopy and enter the forest floor as organic N. Thus, our estimate for global canopy N uptake is uncertain.…”

Human activities have released a large amount of nitric oxides (NOx) into the atmosphere, leading to elevated regional atmospheric NOx concentration and nitrogen (N) deposition. Several studies have observed a downward NOx or NOy (NOx and its oxidation products) flux to the forest canopy, but attributed it to the photochemical reactions and conversion from gaseous N to particulate N. Here, we focus on the possibility of NOx sink by forest canopy based on an observed downward NOx flux of 0.28 kg N ha‐1 yr‐1 in a temperate forest of northeastern China, using hourly monitoring of NOx fluxes. In combination with results from previous studies, we find that the downward NOx or NOy fluxes ranged from 0.2 to 1.4 kg N ha‐1 yr‐1 in temperate forests and from 5.3 to 8.5 kg N ha‐1 yr‐1 in subtropical forests and they were positively related to atmospheric NOx concentration, mean annual air temperature and annual precipitation across 8 forest sites from around the world. If assuming 50% of downward NOx or NOy was directly taken up by the canopy, we estimate a NOx or NOy sink of 0.2 and 1.1 Tg N yr‐1 by global respective temperate and subtropical forests, representing an effective scavenger of atmospheric NOx and a considerable N source to forests. We suggest that interception of NOx or NOy by forest canopy should be considered in global NOx budgets and their contribution to the global forest N pool in global Earth System’s models.

“…Lichenological studies in India started at the beginning of the eighteenth century (Fries 1825), much earlier than the first worldwide monograph of foliicolous lichens, published in 1952 (Santesson 1952). After that, only a few scientists worked on this group in India (Awasthi 2010;Farkas 2014). Recently, Singh and Pinokiyo (2014) worked on the foliicolous lichens of India, but their primary study site was the Eastern Himalayas and they did not made collections from the Western Ghats.…”
