“…Similarly, species such as Nicotiana tabacum incorporated 15% and L. esculentum incorporated 11% NO 2 -N of the overall Nassimilation [3]. These differences in the significance of NO 2 assimilation for N nutrition are the consequences of speciesspecific differences in NO 2 uptake [4]. They are mediated by the complex structural, physiological and genetic make up of leaves that covary with environmental factors.…”

Plants in nature show species-specific nitrogen dioxide (NO 2 ) uptake and a wide variation in NO 2 assimilation. This specific NO 2 uptake or assimilation is affected not only by the structural, physiological and genetic make up of leaves, but also by various environmental factors. This review focuses on the processes of leaf NO 2 uptake. We describe the influence of stomatal traits on foliar NO 2 uptake, discuss the interactions between NO 2 uptake and apoplastic antioxidant (ascorbate and glutathione), and present the roles of cuticles in NO 2 deposition and emission. Further progress is proposed to gain a better understanding of the dynamic uptake of NO 2 and NO 3 -transporters in leaves.

“…A common observation of plants under fumigation by reactive N is an increase in at least some aspects of leaf N (Rowland 1986;Rowland et al 1987;Segschneider et al 1995;Hanstein et al 1999;Takahashi et al 2005) and there is some level of correspondence between natural variation in foliar uptake and leaf N contents (Calanni et al 1999;Tomaszewski and Sievering 2007;Sievering et al 2007). Therefore, foliar uptake has the potential to alter the stoichiometry of C and N in plant tissues in opposition to that driven by elevated CO 2 .…”

Ecological ramifications of the direct foliar uptake of nitrogen

The foliar incorporation of various reactive forms of nitrogen (N) has been identified and studied for nearly 30 years. However, the ecosystem-level ramifications of this uptake pathway have only recently been considered by the scientific community. In this review, I present our current understanding of the foliar uptake process and then discuss why this pathway of N addition to ecosystems should be considered separately from the bulk deposition of N to the soil surface. Direct foliar uptake is a direct addition of N to plant metabolism and could potentially more readily influence plant growth compared to soildeposited N. Current ecosystem process models do not partition reactive N between foliar and soil entry pathways and the influence of N deposition on ecosystem C sequestration is likely inadequately represented in most models. I also outline several research priorities for the future understanding of the ecological consequences of foliar uptake of reactive N.

“…Reducing thermal stress due to shadow casting and transpiration [7][8][9]; • The leaves in the canopy act as a filter for gaseous pollutants (NO 2 , SO 2 , O 3 , CO) and particulate matter (PM 10 , PM 2.5 ) [10][11][12]; • The canopy can intercept huge amounts of water during rainfall [13,14] which leads to decreased storm water runoff; • CO 2 sequestration through photosynthesis helps to reduce greenhouse gases from the atmosphere [15,16]; • Trees provide a habitat for different animal species groups like insects, birds and mammals [17,18] and enhance biodiversity in cities.…”

Cooling Effects and Regulating Ecosystem Services Provided by Urban Trees—Novel Analysis Approaches Using Urban Tree Cadastre Data

Abstract:The provision of ecosystem services by urban trees is not yet routinely integrated in city administrations' planting scenarios because the quantification of these services is often time-consuming and expensive. Accounting for these welfare functions can enhance life quality for city dwellers. We present innovative approaches that may appeal to the numerous city administrations that keep tree inventory or cadastre databases of all trees growing on city property for civil law liability reasons. Mining these ubiquitous data can be a feasible alternative to field surveys and improve cost-benefit ratios for ecosystem service assessment. We present methods showing how data gaps (in particular tree height and crown light exposure) in the cadastre data can be filled to estimate ecosystem services with i-Tree Eco. Furthermore, we used the i-Tree Eco output for a noval approach which focus on predicting energy reduction as a proxy for cooling benefits provided by trees. The results for the total publicly owned and managed street trees in our study site of Duisburg (Germany) show that the most important ecosystem services are the removal of particulate matter by 16% of the city emissions and the reduction of 58% of the direct and thermal radiation in the effective range of the trees in the cadastre.
