Meetings and Symposia

9th SAHRA Annual Meeting

"Climate, Water and Land Cover Chnage in a Non-stationary World," September 23-24 2009, Doubletree Hotel Tucson at Reid Park, 445 S. Alvernon Way, Tucson, AZ 85711.

SAHRA has collaborated with partner institutions Biosphere 2, Institute of the Environment, and the Water Sustainability Program to create a program that kicks off with Dennis Lettenmaier and Julio Betancourt, two authors of the seminal article “Stationarity is Dead: Whither Water Management?” (Science 2008). This will be followed by 14 concurrent sessions addressing different challenges associated with climate change.

6th Annual RISE Symposium

The 6th Research Insights in Semiarid Environments (RISE) Symposium, Saturday, 3 October 2009, 8:30 AM to 2:30 PM. Poster submission deadline is 18 September.

Chapman Conference

"Ecohydrological Feedbacks of Landscape Change Along Elevation Gradients in Semiarid Regions," 4–8 October 2009, Boise and Sun Valley, Idaho USA.

The purpose of this conference is to examine the ecohydrological feedbacks of landscape change along elevation gradients in semiarid regions. We will explicitly examine the ecohydrological changes taking place in these landscapes, across elevation and precipitation gradients. We propose the seemingly simple guiding question, “Are there ecohydrological trends across precipitation gradients?” and then focus our efforts on specifically contrasting the ecohydrology of spatially contiguous precipitation gradients (e.g., elevation gradients) with conceptually organized precipitation gradients (e.g., semiarid vs. more humid systems). Our goal is to help scientists from different disciplinary backgrounds and land managers better understand and address the substantial changes occurring in semiarid landscapes.

10th Biennial Conference of Research on the Colorado Plateau

“Collaborative Conservation in Rapidly Changing Landscapes,” October 5 - 8, 2009 High Country Conference Center Flagstaff, Arizona.

Plenary Speaker: Paul Ehrlich - author of "The Population Bomb" and co-author of "The Dominant Animal: Human Evolution and the Environment. A 4-day solution-oriented conference about the most pressing conservation issues facing not only the Southwest and West. This conference provides an interdisciplinary forum to explore research and land management issues related to the biological, cultural, and economic resources of the Colorado Plateau, Southwestern United States, and Mexico. The conference includes symposia, oral presentations, workshops, discussion groups, and short courses.

NSF Project takes a new look at decomposition in drylands

Steve Archer and Dave Breshears are teaming up with Paul Barnes (Loyola University-New Orleans), Rebecca McCulley (University of Keytucky) and Heather Throop (New Mexico State University) to look at how photodegradation and erosion interact to influence decomposition in arid ecosystems

Rangeland ecosystems support half of the world’s livestock while also providing habitats for some of the most charismatic of wildlife species. This book examines the pressures on rangeland ecosystems worldwide from human land use, over-hunting, and subsistence and commercial farming of livestock and crops. Leading experts have pooled their experiences from all continents to cover the ecological, sociological, political, veterinary, and economic aspects of rangeland management today.

* The first book to examine rangelands from a conservation perspective

* Emphasizes the balance between the needs of people and livestock, and wildlife

* Written by an international team of experts covering all geographical regions

* Examines ecological, sociological, political, veterinary, and economic aspects of rangeland management and wildland conservation, providing a diversity of perspectives not seen before in a single volume

Dr. Archer authored Chapter 4 "Rangeland conservation and shrub encroachment: new perspectives on an old problem.
