Experimental warming changes phenology and shortens growing season of the dominant invasive plant Bromus tectorum (cheatgrass) Experimental warming changes phenology and shortens growing season of the dominant invasive plant Bromus tectorum (cheatgrass)
Bromus tectorum (cheatgrass) has successfully invaded and established throughout the western United States. Bromus tectorum grows early in the season and this early growth allows B. tectorum to outcompete native species, which has led to dramatic shifts in ecosystem function and plant community composition after B. tectorum invades. If the phenology of native species is unable to track...

Getting to the root of restoration: Considering root traits for improved restoration outcomes under drought and competition Getting to the root of restoration: Considering root traits for improved restoration outcomes under drought and competition
A foundational goal of trait‐based ecology, including trait‐based restoration, is to link specific traits to community assembly, biodiversity, and ecosystem function. Despite a growing awareness of the importance of belowground traits for ecological processes, a synthesis of how to root traits can inform restoration of terrestrial plant communities is lacking. We reviewed and summarized...

Seasonal and individual event-responsiveness are key determinants of carbon exchange across plant functional types Seasonal and individual event-responsiveness are key determinants of carbon exchange across plant functional types
Differentiation in physiological activity is a critical component of resource partitioning in resource-limited environments. For example, it is crucial to understand how plant physiological performance varies through time for different functional groups to forecast how terrestrial ecosystems will respond to change. Here, we tracked the seasonal progress of 13 plant species representing...

Unexpected hybridization reveals the utility of genetics in native plant restoration Unexpected hybridization reveals the utility of genetics in native plant restoration
Native plant materials (NPMs) are increasingly utilized during the restoration of disturbed plant communities. Here, we analyze next‐generation genetic sequencing data for Hilaria jamesii, a dominant graminoid across drylands of the southwestern United States, and document that the species' only commercially‐available NPM, ‘Viva’, is a hybrid between H. jamesii and its sister species, H...

Assessment of population genetics and climatic variability can refine climate‐informed seed transfer guidelines Assessment of population genetics and climatic variability can refine climate‐informed seed transfer guidelines
Restoration guidelines increasingly recognize the importance of genetic attributes in translocating native plant materials (NPMs). However, when species‐specific genetic information is unavailable, seed transfer guidelines use climate‐informed seed transfer zones (CSTZs) as an approximation. While CSTZs may improve how NPMs are developed and/or matched to restoration sites, they overlook...

A primary focus of the Bureau of Land Management’s (BLM’s) Colorado Plateau Native Plant Program (CPNPP) is to identify and develop appropriate native plant materials (NPMs) for current and future restoration projects. Multiple efforts have characterized the myriad challenges inherent in providing appropriate seed resources to enable effective, widespread restoration and have identified...

Local, temporal trajectories explain population-level responses to climate change in saguaro (Carnegiea gigantea) Local, temporal trajectories explain population-level responses to climate change in saguaro (Carnegiea gigantea)
Population demography is typically assumed to be strongly influenced by climatic factors, particularly with succulent plants and cacti. The saguaro cactus (Carnegiea gigantea) is a long‐lived columnar cactus of the Sonoran Desert that experiences episodic recruitment and mortality. Previous studies have attributed long‐term changes in saguaro populations to climatic factors, including...

Earlier plant growth helps compensate for reduced carbon fixation after 13 years of warming Earlier plant growth helps compensate for reduced carbon fixation after 13 years of warming
1. Drylands play a dominant role in global carbon cycling and are particularly vulnerable to increasing temperatures, but our understanding of how dryland ecosystems will respond to climatic change remains notably poor. Considering that the area of drylands is projected to increase 11–23% by 2100, understanding the impacts of warming on the functions and services furnished by these arid...

Contemporary human impacts on alpine ecosystems: the direct and indirect effects of human-induced climate change and land use Contemporary human impacts on alpine ecosystems: the direct and indirect effects of human-induced climate change and land use
Alpine ecosystems account for ca. 3 % of terrestrial habitats yet, along with adjacent mountain systems, provide water resources to nearly half of the world’s human population. Approximately 20 % of humans live in or near mountain areas, making it inherently important to understand current impacts on these systems. Here, I review literature regarding current and projected human impacts...

Shrub persistence and increased grass mortality in response to drought in dryland systems Shrub persistence and increased grass mortality in response to drought in dryland systems
Droughts in the southwest United States have led to major forest and grassland die‐off events in recent decades, suggesting plant community and ecosystem shifts are imminent as native perennial grass populations are replaced by shrub‐ and invasive plant‐dominated systems. These patterns are similar to those observed in arid and semiarid systems around the globe, but our ability to...

Beyond traditional ecological restoration on the Colorado Plateau Beyond traditional ecological restoration on the Colorado Plateau
The Colorado Plateau is one of North America's five major deserts, encompassing 340,000 km2 of the western U.S., and offering many opportunities for restoration relevant to researchers and land managers in drylands around the globe. The Colorado Plateau is comprised of vast tracts of public land managed by local, state, and federal agencies that oversee a wide range of activities (e.g...
