Mitch McClaran introducing the 17th RISE Symposium

Mitch McClaran introducing the 17th RISE Symposium in the Marley building.

On Saturday 20 November 2021, 59 people attended the 17th Annual RISE (Research Insights in Semi-Arid Environments) Symposium. It was a hybrid symposium, with 35 people attending in person in the Marley Building on the University of Arizona campus and 24 people attending remotely through a Zoom Webinar format. It was a joyous occasion because we did not meet last year because of the Covid pandemic. You can find the program at http://www.tucson.ars.ag.gov/rise/index.htm

The objectives of the symposium are to share recent results of scientific research in semiarid environments, with an emphasis on work conducted at the USDA-ARS Walnut Gulch Experimental Watershed (WGEW) and the University of Arizona Santa Rita Experimental Range (SRER), and to encourage future research and outreach activities.

This year, 12 speakers (6 in-person and 6 remote) covered a wide variety of topics, and some included results of work completed and on-going at WGEW or SRER. The topics ranged across micro to regional spatial scales, and from seconds to century temporal scales. Abe Karam and Bridget Hass from NEON provided updates dates and Airborne Observation Platform data access advice. Andy Hubbard from the National Park Service and Larry Fisher from Cienega Watershed Partnership provided updates on citizen science and indicators of watershed health. Access and analysis of big data were discussed by Tyson Swetnam and Guillermo Ponce, both from University of Arizona. Marguarite Mauritz from University of Texas El Paso presented long term data on carbon fluxes at the Jornada Experimental Range, and Dave Goodrich from USDA ARS Southwest Watershed Management Research Center described trends in 30-sec to several minutes maximum rain events at WGEW and across the continent. Sheri Spiegal from USDA ARS at the Jornada Experimental Range described ongoing work documenting and assessing the beef supply chain in the western US, and Gary Nabhan from the University of Arizona described work to catalog and protect wild crop relatives in southern Arizona so they can provide future crop resources. In short, there was never a dull moment.

These presentations will be archived at http://www.tucson.ars.ag.gov/rise/index.htm, where we also provide presentations and poster from the previous 15 symposia.

The highlight was the 1.5-hour poster session where 18 presenters (12 in-person) led a cacophony of discussion in the Marley Building foyer. Through a generous contribution from long-time supporter Mr. Malcolm McGregor, there were monetary awards for the Best Graduate and Undergraduate posters reporting research performed by students working at WGEW or SRER, or using data collected at those facilities. These posters are available for viewing at http://www.tucson.ars.ag.gov/rise/index.htm

Members of the Tierra Seca Club, which is the student chapter of the Society for Range Management provided coffee, juice, fruit, cheese, and baked goodies for attendees before the talks began at 9 am. The Club will use donations for providing these goodies to help cover travel expenses to the national meeting of the Society for Range Management this February 2022 in Colorado.

Mitch McClaran presenting the 2019 RISE Symposium

On Saturday 26 October 2019, 56 people attended the 16th Annual RISE (Research Insights in Semi-Arid Environments) Symposium in the Marley Building on the University of Arizona campus.

The objectives of the symposium were to share recent results of scientific research in semiarid environments, with an emphasis on work conducted at the USDA-ARS Walnut Gulch Experimental Watershed (WGEW) and the University of Arizona Santa Rita Experimental Range (SRER), and to encourage future research and outreach activities.

This year, 10 speakers covered a wide variety of topics, and some included results of work completed and on-going at WGEW or SRER. The topics ranged across micro to regional spatial scales, and from seconds to century temporal scales. Betsy Arnold discuss soil microbial influences on seed germination and success at the micro-scale, while John Humphreys presented regional-scale information about the transmission and outbreak of livestock diseases. Enrique Vivoni described carbon, heat and water exchange rates with measurements per second, Mike Duniway described responses of vegetation to alterations of precipitation regimes at the 3-year scale, and Dave Bertelsen described 36 years of vegetation change along the Mount Kimball trail in the Catalinas Mountains at the weekly scale. In short, there was never a dull moment.

These presentations and posters are archived at the RISE webpage,where we also provide presentations and poster from the previous 15 symposia.

The highlight was the 1.5-hour poster session where 9 presenters led a cacophony of discussion in the Marley Building foyer.

On Saturday 20 October 2018, 73 people attended the 15th Annual RISE (Research Insights in Semi-Arid Environments) Symposium in the Marley Building on the University of Arizona campus.
Program and presentations are available at RISE 2018.

The objectives of the RISE symposia are to share recent results of scientific research in semiarid environments, with an emphasis on work conducted at the USDA-ARS Walnut Gulch Experimental Watershed (WGEW) and the University of Arizona Santa Rita Experimental Range (SRER), and to encourage future research and outreach activities.

This year, 13 speakers covered a wide variety of topics, and some included results of work completed and ongoing at WGEW or SRER. Access to publically-available data, increase in wireless data access at the SRER, CyVerse supported data processing capacity, handling and interpreting big data from remote sensing campaigns, spatial and temporal patterns of precipitation intensity, and expression of deep geologic time in soil and landscape development were covered in the morning session. The afternoon session had more focus on organism behavior and ecology, including soil microbial abundance in relation to soil and soil-water qualities, behavior of aquatic invertebrates as a driving mechanism in the abundance and distribution in southwestern streams, tools and data sets to study phenology patterns, and long-term studies of human and desert plant dynamics on Tumamoc Hill operated by the UA Desert Lab. During their presentations, several speakers solicited collaborators for future work and with publically-accessible data, and most prominent in that behavior was Dr. Heather Throop who is 5 years into a 30 NSF-funded project that manipulates leaf litter inputs in grasslands and mesquite settings, and several attendees are pursuing collaborations with her as a result.

These presentations and posters are archived at the RISE webpage, where we also provide presentations and posters from the previous 14 symposia.

The highlight was the 1.5-hour poster session where 14 presenters led a cacophony of discussion in the Marley Building foyer.
