A study to explore the use of orbital remote sensing to determine native arid plant distribution [PDF]

open access: yes, 1974
The author has identified the following significant results. It is possible to determine, from ERTS imagery, native arid plant distribution. Using techniques of multispectral masking and extensive fieldwork, three native vegetation communities were ...

Impacts of reclamation approaches on plant establishment in an arid environment during copper mine revegetation

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Revegetation using native vegetation is a commonly used technique to reclaim landscapes degraded by mining activities. Revegetation efforts in the arid Southwestern United States face physical, geochemical, hydrological, and biological challenges unique to drylands.

Population dynamics of Townsend's big‐eared bats: effect of age and drought on survival

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
We estimated age‐specific yearly survival of female Townsend's big‐eared bats in Inyo and Mono Counties, California. We found that both juvenile and adult survival were negatively impacted by drought, and that detection probability was lower for hand‐recapture than for bats detected via pass‐through antenna arrays.

Insights Into Spatial Orientation and Cognition in Tarantulas (Araneae: Theraphosidae) Under Natural Conditions, With Notes on Possible Ontogenetic Niche Shifts

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Cognitive studies on spiders have largely ignored mygalomorphs, such as tarantulas, and almost completely lack field‐based observations. We present nine observations of arboreal and fossorial New World tarantulas, including a blind cave‐dwelling species, providing evidence for possible experience‐based navigation and spatial learning during foraging ...

Creosote Bush, an Arid Zone Survivor in Southwestern U.S.: 1. Identification of Morphological and Environmental Factors that Affect Its Growth and Development

open access: yes, 2017
Creosote bush (Larrea tridentata [DC.] Cov.) is a perennial shrub which is a major dominant species in arid rangelands in southwestern Texas, U.S. Controlling creosote bush in desert rangelands is important because as it increases in density, perennial ...

Herbaceous plant communities respond more to seasonal precipitation than cumulative drought in the hot deserts of the United States

open access: yesPlant Biology, Volume 28, Issue 3, Page 860-871, April 2026.
Using a 4‐year drought experiment in the hot deserts of the US, we found that herbaceous plant communities were more sensitive to seasonal precipitation than to the cumulative effects of drought. Abstract The hot deserts of the southwestern United States are experiencing increased frequency, severity, and duration of drought due to anthropogenic ...

Shrubs indirectly increase desert seedbanks through facilitation of the plant community [PDF]

open access: yes, 2019
The mechanisms supporting positive ecological interactions are important. Foundation species can structure desert biodiversity by facilitating seedbanks of annual plants, but the direct and indirect mechanisms of shrub effects on seedbank have not been ...

Artificial shelters provide microclimatic refuges from increasing desertification for resident vertebrates

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
This study evaluated whether artificial shelters can mimic the microclimatic benefits of foundation shrubs to support vertebrate biodiversity in dryland ecosystems facing desertification. Surveys conducted at Californian desert sites (2022–2023) showed that artificial shelters increased vertebrate abundance and richness, performing comparably to native
