title = "Plant gas exchange and water status in urban desert landscapes",
abstract = "Gas exchange and water status were evaluated for plants at irrigated residential and unirrigated remnant Sonoran Desert sites in the greater Phoenix area, Arizona, U.S.A. Gas exchanges fluxes were higher for plants at the residential sites than for those at the desert sites. Plant water status was more favorable at residential sites for every season except the late summer monsoon, and time of day for maximum photosynthesis was later for residential plants during summer and winter months. These data suggest that yearly CO2 uptake was a function of plant water status and summer heat stress, and land use in these urban desert landscapes.",

note = "Funding Information: In urban environments, plant CAP is considered an ecological benefit, but in desert systems, this benefit must be weighed against the need to conserve water, both in terms of ecosystem benefit and plant physiological function. Our research showed that CAP of irrigated residential vegetation was higher than that of surrounding, unirrigated desert vegetation. If these data are considered in conjunction with canopy coverage data, a typical residential landscape site might be expected to have more than 8 times the maximum CAP of an undisturbed desert plot (relative canopy cover times C uptake potential comparisons). These calculations do not reflect possible disparities in canopy density, which might further increase the magnitude of difference in maximum CAP between irrigated residential and unirrigated desert vegetation. We express our appreciation to Kathleen A. Peterson for assistance in data collection and analysis. This research was funded in part by a research grant from the National Science Foundation grant no.
