Past Symposia:

The 14th annual Research Insights in Semiarid Ecosystems (RISE) Symposium will be held Saturday, 21 October 2017, 8:30 AM to 3:00 PM on the University of Arizona campus.  The objectives of the symposium are to share recent results of research at the USDA-ARS Walnut Gulch Experimental Watershed (WGEW) and the University of Arizona Santa Rita Experimental Range (SRER), to encourage future research activities at the WGEW and the SRER, and to promote the WGEW and the SRER as outdoor scientific laboratories.

The Symposium will feature invited speakers presenting recent or on-going research on the WGEW, the SRER or other outdoor laboratories in the region. There will be time for questions from the audience, which will consist of federal agency, NGO (non-governmental organization) and university researchers, students, and stakeholders from southern Arizona. 


The deadline for registration (as a courtesy for catering plans) is 10 October 2017. Late registrations will be accepted at the Symposium site on October 21  from 8:30 to 9:00 AM.

The deadline for Poster Abstract Submission is 10 October 2017.  Note: Space may be limited; if this is the case, priority will be based on order of abstract submission.

Poster Session Guidelines:

Poster Dimensions (applies to all posters, including student contestants and others):  

Posters should not exceed 4 feet (48 inches) by 5 feet (60 inches). 

Student Poster Contest Awards:

Through a generous contribution from long-time supporter Mr. Malcolm McGregor, we are able to grant monetary awards for outstanding student posters.  A single award will be granted in each of the following categories:

To qualify for a poster award, the work presented on the poster must have been conducted on or have used data from the WGEW, the SRER, or both.  Entry to the contest is made via the symposium registration link above.

Contestant's posters will be judged and awards presented at the close of the Symposium. A poster should stand on its own merit, but poster judges will also be visiting with each student at their posters to evaluate enthusiasm and competence in the subject area. Note: Students in the competition will be asked to identify at least a 30 minute window in which they will be at their poster during the poster session.
