Abstract:	The primary objective of this project is to understand how long-term climate variability and change influence the structure and function of desert streams via effects on hydrologic disturbance regimes. Climate and hydrology are intimately linked in arid landscapes; for this reason, desert streams are particularly well suited for both observing and understanding the consequences of climate variability and directional change. Researchers try to (1) determine how climate variability and change over multiple years influence stream biogeomorphic structure (i.e., prevalence and persistence of wetland and gravel-bed ecosystem states) via their influence on factors that control vegetation biomass, and (2) compare interannual variability in within-year successional patterns in ecosystem processes and community structure of primary producers and consumers of two contrasting reach types (wetland and gravel-bed stream reaches). These data were collected to understand how climate change alters flood-mediated delivery of the limiting resource, nitrogen. Specifically, how does the amount of winter rainfall and the number, timing, and intensity of winter and monsoon floods alter N delivery. Previous research indicates that nitrogen is a limiting element in Sycamore Creek, and that pulses of nitrogen enter the system from the landscape during winter rains and summer monsoons. Nitrogen in high concentrations can be a pollutant so consideration of downstream export is a consideration. Researchers collected water samples during storms to compare inter- and inter-annual variability in storm dynamics, and to examine the pulse of various nutrients associated with these events.

Methods and protocols used in the collection of this data package

Description:

An automatic water sampler (ISCO 6700 portable sampler) triggered with either a liquid level actuator or bubble module was deployed at the Dos S Ranch adjacent to Sycamore Creek. Periodic adjustments were needed to the location and setting of the instrument based on the dynamism of the streambed, but generally events resulting in a discharge of > 40 cfs as recorded by the downstream USGS guage (09510200). Once triggered, 450 mL samples were collected every 15 minutes for the first 12 samples and then once an hour. Samples were retrieved from the field within 24 hours in conjunction with the collection of two grab samples from the stream in 1-L bottles and brought back to the lab on ice where they were filtered using ashed Whatman GFF filters. From each ISCO and grab bottle, two replicates were produced for each analysis. Filtrate was stored in Falcon tubes and frozen until analyzed. NH4 samples were not filtered but frozen and later centrifuged before analysis. NO3, NH4, SRP, and Cl- were analyzed using flow injection analysis (Lachat QC8000). DOC and TN were analyzed using total organic carbon/ nitrogen analysis (Shimadzu TOV-C). Known standard concentrations and blank samples were run every 10 field samples to ensure quality control.

Abstract:

Phase IV of the Central Arizona-Phoenix LTER (CAP) continues to focus on the question: How do the ecosystem services provided by urban ecological infrastructure (UEI) affect human outcomes and behavior, and how do human actions affect patterns of urban ecosystem structure and function and, ultimately, urban sustainability and resilience? The overarching goal is to foster social-ecological urban research aimed at understanding these complex systems using a holistic, ecology of cities perspective while contributing to an ecology for cities that enhances urban sustainability and resilience. This goal is being met through four broad programmatic objectives: (1) use long-term observations and datasets to articulate and answer new questions requiring a long-term perspective; (2) develop and use predictive models and future-looking scenarios to help answer research questions; (3) employ existing urban ecological theory while articulating new theory; and (4) build transdisciplinary partnerships to foster resilience and enhance sustainability in urban ecosystems while educating urban dwellers of all ages and experiences. CAP IV research is organized around eight interdisciplinary questions and ten long-term datasets and experiments, and researchers are organized into eight Interdisciplinary Research Themes to pursue these long-term research questions.

Abstract:

The primary objective of this project is to understand how long-term climate variability and change, as expressed through hydrologic regime shifts, influence the structure and function of desert streams. Desert streams are well suited for observing the consequences of climate variability because they experience high hydrologic variability at multiple scales. Researchers will determine how regime shifts influence 1) large-scale stream biogeomorphic structure (i.e., prevalence and persistence of wetlands) over multiple years via their influence on factors that control vegetation biomass, and 2) within-year successional patterns in ecosystem processes and community structure of primary producers and consumers of reaches along a gradient of wetland presence and stability. Arid regions are characterized by high interannual variation in precipitation, and these climate patterns drive the overall disturbance regime (in terms of flooding and drying), which influences the geomorphic structure and nutrient status of desert stream ecosystems. Embedded within the multi-annual hydrologic regime, flash floods scour stream channels and initiate a series of rapid successional changes by benthic algae, aquatic and wetland plants, and macroinvertebrates at short time scales (i.e., within a year); patterns of succession are hypothesized to vary among years within the long-term hydrologic regime. The research will use new techniques developed by the team to analyze the relationships between hydrologic variability, hydrologic regime shifts, and ecosystem and community properties.
