Drought resistance drives population temporal stability of annuals in drylands
We examined how functional traits determine population temporal stability in 178 populations of winter annuals across Mediterranean, semi‐arid and arid climates over 13 years. Traits conferring higher drought resistance were consistently associated with greater stability in open habitats, whereas shrub microhabitats altered or reversed this pattern ...

An iterative and targeted sampling design informed by habitat suitability models for detecting focal plant species over extensive areas [PDF]
Prioritizing areas for management of non-native invasive plants is critical, as invasive plants can negatively impact plant community structure. Extensive and multi-jurisdictional inventories are essential to prioritize actions aimed at mitigating the ...

Abstract Drylands are among the most degraded ecosystems globally and are difficult to restore due to limited water availability. Biocrusts are a key component of maintaining soil stability and function in these systems. Since biocrust salvage opportunities are limited, cultivating salvaged biocrusts is a promising method.

Abstract Spring dust storms in the U.S. Southwest significantly impact environmental and human systems, yet their climatological patterns and driving mechanisms remain poorly understood. Using two decades of MERRA‐2 reanalysis data and self‐organizing map clustering, we identified four distinct dust transport pathways from surrounding and remote ...

Resource availability and heterogeneity affect space use and resource selection of a feral ungulate
Animals adjust their habitat use patterns in response to changes in their physiological needs and environmental conditions. Understanding the mechanisms underlying resource selection and space use across time and space reveals effects of the environment ...
