Key Message Female cuttings of Populus deltoides were sensitive to inorganic nitrogen forms and biased for NO 3 2 -N, whereas males exhibited no obvious preference for nitrogen form in nitrogen fertilizations. Abstract We investigated the effects of different inorganic nitrogen forms (NO 3 --N and NH 4 ? -N) on the morphology, physiology, and carbohydrate accumulation of male and female Populus deltoides. Results showed that both NO 3 --N and NH 4 ? -N supply forms significantly increased plant growth, C and N contents of all plant organs, chlorophyll pigment contents, net photosynthesis rates (P n ), and instantaneous photosynthetic N-use efficiencies (PNUE) in the leaves of both male and female P. deltoides. Females exhibited high total plant dry mass accumulation, P n , PNUE, and N contents in leaves but lower non-structure carbohydrate accumulation than males under nitrate treatment. However, males showed significantly higher P n , PNUE, and 15 NH 4 ? in the leaves, free amino acid content, and nitrate reductase (NR) activities than females under each nitrogen form supply treatment.These results suggested that male and female P. deltoides used different adaptive strategies in dry mass accumulation, allocation, and exhibited different interactions between nitrogen and carbon metabolism. Males exhibited higher nitrogen assimilation ability and N-use efficiency than females under nitrogen fertilizations, whereas females showed more sensitivity to inorganic nitrogen forms of treatments and distinct preference for NO 3 --N. Male P. deltoides showed no obvious bias to the two different N forms. Therefore, the different preferences of male and female P. deltoides of N supplied forms can serve as an important strategy for minimizing intraspecific competition between the two genders.

“…NH4 + is preferentially taken up by Sphagnum (Fritz et al, 2014;Liu et al, 330 2013; Wiedermann et al, 2009) because Sphagnum has a high cation exchange capacity 331 (Bates, 1992;Gunnarsson & Rydin, 2000). In addition, NH4 + has greater toxicity 332 (Gerendás et al, 1997;Krupa, 2003;Stevens et al, 2011). DON concentration in pore water (Fig.…”

“…High atmospheric NH 3 concentrations are directly toxic to plants through stomatal uptake as soon as the uptake exceeds the detoxification capacity (Fangmeier et al, 1994). Ammonia deposition (and deposition of other forms of reactive N) can lead to eutrophication and acidification of sensitive ecosystems, causing changes in biodiversity (Cape et al, 2009b;Cellier et al, 2009;Krupa, 2003;Pitcairn et al, 2009). Studies have been conducted to quantify the effect of NH 3 emission sources on surrounding ecosystems, e.g.…”

AbstractWe examined the consequences of the spatial heterogeneity of atmospheric ammonia (NH 3 ) by measuring and modelling NH 3 concentrations and deposition at 25 m grid resolution for a rural landscape containing intensive poultry farming, agricultural grassland, woodland and moorland. The emission pattern gave rise to a high spatial variability of modelled mean annual NH 3 concentrations and dry deposition. Largest impacts were predicted for woodland patches located within the agricultural area, while larger moorland areas were at low risk, due to atmospheric dispersion, prevailing wind direction and low NH 3 background. These high resolution spatial details are lost in national scale estimates at 1 km resolution due to less detailed emission input maps. The results demonstrate how the spatial arrangement of sources and sinks is critical to defining the NH 3 risk to seminatural ecosystems. These spatial relationships provide the foundation for local spatial planning approaches to reduce environmental impacts of atmospheric NH 3 . Capsule:Fine scale resolution modelling to reproduce the spatial heterogeneity of atmospheric NH 3 concentrations and deposition is critical for NH 3 risk assessment on sensitive ecosystems. Highlights:• Local farm inventory provided field-level emissions for high resolution modelling• Model-derived concentrations were compared against intensive spatial measurements• Spatial arrangement of NH 3 sources and sinks is critical to environmental impact• Average national emission factors were not appropriate for an NH 3 risk assessment• Modelling at 1 km resolution did not capture the full spatial variability of NH 3
