Contrasting Geographic Patterns of Ignition Probability and Burn Severity in the Mojave Desert

Frontiers in Ecology and Evolution, 2021
The extent and frequency of fire has increased in many arid systems over the last century, with a large proportion of area in some regions undergoing transitions to novel conditions.

Biocrust restoration in novel climates: assisted migration, habitat amelioration, and varied community composition as climate‐smart techniques

Restoration Ecology, EarlyView.
Abstract Introduction Successful restoration of terrestrial drylands depends on stable, fertile soils that retain water. These functions are provided by biological soil crusts (biocrust), suggesting their reestablishment is a critical step in dryland restoration.

Biological and Proteolytic Variation in the Venom of Crotalus scutulatus scutulatus from Mexico

Toxins, 2018
Rattlesnake venoms may be classified according to the presence/absence and relative abundance of the neurotoxic phospholipases A 2 s (PLA 2 s), such as Mojave toxin, and snake venom metalloproteinases (SVMPs).

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

The linkages among hillslope-vegetation changes, elevation, and the timing of late-Quaternary fluvial-system aggradation in the Mojave Desert revisited [PDF]

Earth Surface Dynamics, 2014
Valley-floor-channel and alluvial-fan deposits and terraces in the southwestern US record multiple episodes of late-Quaternary fluvial-system aggradation and incision.

Natural and Anthropogenic Drivers of Genomic Diversity in the California Towhee: Conservation Implications for Peripheral Populations

Evolutionary Applications, Volume 19, Issue 8, August 2026.
ABSTRACT Demographic, geographic, and environmental factors such as effective population size, isolation, and habitat availability interact to shape contemporary levels of population genomic diversity. Such factors must be carefully evaluated and contextualized at both the intraspecific and interspecific levels when assessing the conservation status of

Decadal-scale soil redistribution along hillslopes in the Mojave Desert [PDF]

Earth Surface Dynamics, 2015
This study estimates the relative magnitude of decadal-scale soil redistribution (i.e., soil loss or gain) by slope wash using 137Cs inventories measured in 46 soil profiles at four study sites in the Ft.

Impacts of Quaternary Climate History on the Biogeography of Specialized Butterflies in the Great Basin of North America

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Dramatic Quaternary climate fluctuations impacted the evolutionary history and contemporary biogeography of many residents of the Great Basin Desert of western North America. This study investigates the historical biogeographic processes that shaped the contemporary distribution of genetic variation in a polytypic group of specialized ...

High quality draft genome sequences of Mycoplasma agassizii strains PS6T and 723 isolated from Gopherus tortoises with upper respiratory tract disease

Standards in Genomic Sciences, 2018
Mycoplasma agassizii is one of the known causative agents of upper respiratory tract disease (URTD) in Mojave desert tortoises (Gopherus agassizii) and in gopher tortoises (Gopherus polyphemus). We sequenced the genomes of M. agassizii strains PS6T (ATCC

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2388-2415, August 2026.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...
