However, treatment wetlands 16 located in aridland cities may behave differently relative to their more mesic and humid 17 counterparts, and this could potentially impact their ability to deliver the ecosystem services that 18 are expected of them. Specifically, in hot, dry climates large water losses via evaporation and 19 plant transpiration may comprise a major component of whole-system water budgets. and from the whole wetland system and into the vegetated marsh. We found that water losses 27 due to transpiration and evaporation were remarkably high when compared to most mesic 28 constructed wetlands. Total water losses via evaporation and transpiration peaked at 300,000 m

Urbanized areas increasingly rely on constructed treatment wetlands (CTW) for cost 9 effective and environmentally-based wastewater treatment. Constructed treatment wetlands are 10 particularly attractive treatment options in arid urban environments where water reuse is 11 important for dealing with scarce water resources. Emergent macrophytes play an important role 12 in nutrient removal, particularly nitrogen (N) removal, in CTW. However, the role of plant 13 community composition in nutrient removal is less clear. Numerous studies have shown that 14 macrophyte species differentially affect N uptake processes (e.g.: direct plant uptake, coupled 15 nitrification-denitrification, soil accretion). However, many of these studies have been based on 16 small-scale experiments and have been carried out in mesic environments, which means that 17 their findings are difficult to extrapolate to aridland CTW systems. Our study sought to examine 18 the relationships among emergent macrophyte productivity, plant community composition, and 19 N uptake [by both the plants and the entire ecosystem] at a 42 ha CTW in arid Phoenix, Arizona, 20 USA. We quantified above-and belowground biomass bimonthly and foliar N content annually 21 for four species groups (Typha latifolia + T. domingensis., Schoenoplectus californicus + S. 22 tabernaemontani, Schoenoplectus acutus, and Schoenoplectus americanus) from July 2011 to 23 September 2013. We quantified dissolved inorganic N fluxes into and out of the system and 24 compared plant N removal to total system fluxes. Additionally, we estimated monotypic N 25 content for each to compare the system's current community composition and plant N removal to 26
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
