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). This dataset addresses patterns of nutrient limitation by primary producers as indicated by in situ growth on artificial substrates.

Methods and protocols used in the collection of this data package

Description:

# Procedure 1. See Tank et al. 2006 Nutrient Diffusing Substrata (NDS) method. 2. Four agar treatments (control, +NaNO3, KH2PO4, + NaNO3 & KH2PO4) were prepared and poured into labeled Polycon cups (Maden Plastic's) with pre-drilled lids. Fritted glass disks with diameter of 2.7 cm were placed on top of agar and lids securely shut. 3. Cups were attached randomly to L-bars using silicone caulk and different colored zip-ties. One color was designated for each treatment to ensure sample recognition after incubation. 4. L-bars were wrapped in plastic wrap and kept in the refrigerator for no more than 36 hours. 5. L-bars were secured to the stream bed parallel to streamflow using tent stakes. 6. Disks were allowed to accumulate biofilm in the stream. Incubation time is indicated by "Days_in_field" (at least 20 days if field is blank). 7. Chlorophyll a and pheophytin a were analyzed using a hot methanol extraction method (Tett et al. 1975, Tett et al. 1977). Absorbance values were measured using a Beckman DU® 530 Spectrophotometer. # Calculations - Negative 750 nm turb numbers were changed to zero - All absorbance values were background corrected - Chl a (mg/m2) = (219.2 \times v \times ((ABS_666-ABS_750)-(ABS_666a-ABS_750a)))/A - Pheophytin a(mg/m2) = (219.2 \times v ((ABS_666a-ABS_750a \times 3.8)-(ABS_666-ABS_750)))/A - 219.2 is the absorption coefficient for chlorophyll a in methanol \times 10 for conversion from ug/cm2 to mg/m2 - v is the extraction volume of solvent in mL - A is area of fritted glass disk, 5.7255 cm2 - 3.8 is the maximum ratio of (ABS_666-ABS_750): (ABS_666a-ABS_750a) in the absence of pheopigments # References - Tank, J., Bernot, M., & Rosi-Marshall, E. 2006.

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.
