Warming as a Driver of Vegetation Loss in the Sonoran Desert of California
Journal of Geophysical Research: Biogeosciences, 2021Dryland ecosystems cover large regions of the Earth and have important impacts on global biogeochemistry and the carbon cycle. The plant species that occupy dryland environments have traits that enable them to withstand harsh environmental conditions ...

Leaf water relations reflect canopy phenology rather than leaf life span in Sonoran Desert trees.
Tree Physiology, 2021Plants from arid environments display covarying traits to survive or resist drought. Plant drought resistance and ability to survive long periods of low soil water availability should involve leaf phenology coordination with leaf and stem functional ...

Shutting down dust emission during the middle Holocene drought in the Sonoran Desert, Arizona, USA
Geology, 2021Long-term relationships between climate and dust emission remain unclear, with two prevailing but opposite hypotheses for effects of climate shifts: (1) increased dust emission due to increasing aridity imposing a vegetation change, or (2) decreased dust

On the Misclassification of Dust as Cloud at an AERONET site in the Sonoran Desert
Journal of Atmospheric and Oceanic Technology, 2021Here we present retrievals of aerosol optical depth τ from an Aerosol Robotic Network (AERONET) station in the southeastern corner of California, an area where dust storms are frequent.

Soil erosion from urbanization processes in the Sonoran Desert, Arizona, USA
Land Degradation and Development, 2018Cattle stock ponds on the fringe of metropolitan Phoenix, USA, experienced a wide range of land‐use changes over the period from 1989 to 2009. This research measures soil erosion from watersheds of different rock types, variable relief, and land uses ...

Judged either by the diversity of life-forms to be found in it, or by the number of species making up its flora, the Sonoran Desert supports the most complex vegetation of the four arid regions of North America. At its most varied, in the upland situations of southern Arizona where broken terrain produces a variety of micro-climates and where coarse ...

Photosynthetic characteristics of Sonoran Desert winter annuals
Oecologia, 1983Photosynthesis in Sonoran Desert winter annuals appeared to be similar to those observed in other C3 photosynthetic pathway herbs, although photosynthetic capacities ranged from 18 to 65 μmol CO1 m(-2) s(-1) under natural conditions. The higher photosynthetic capacities were associated with high leaf conductances to water vapor (up to 39 mm s(-1 ...

Human Ecology of the Sonoran Desert
Yearbook of the Association of Pacific Coast Geographers, 1998The regional boundaries of the Sonoran Desert were first described by John Harshberger in 1911 and refined by Forrest Shreve in the 1940s on the basis of the desert’s unique vegetation and flora. It is roughly divided by the U.S./Mexico international boundary with about 60 percent in Mexico.
