A matter of timing: sagebrush steppe restoration seeding outcomes altered by species responses to warmer spring temperatures and interannual weather variation

Restoration Ecology, EarlyView.
Abstract Introduction Restoration outcomes in cold desert ecosystems like sagebrush steppe are affected by weather variability, particularly during the spring, a critical time period for seedling establishment. Seedling emergence phenology is also highly variable among species in these ecosystems.

Moose indifferent to canopy loss from forest disturbance by bark beetles

The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Moose showed strikingly similar patterns of habitat selection before and after widespread forest disturbance following an infestation of bark beetles. Our findings indicate that beetle‐kill does not appreciably alter habitat quality for moose and highlight the importance of riparian areas in sustaining moose as they contend with changing forests ...

Earlier fall precipitation and low severity fire impacts on cheatgrass and sagebrush establishment

Ecosphere, 2020
In arid and semiarid ecosystems, invasion by exotic grasses may be driving state changes in vegetation defined by losses of native shrub communities.

Interactions of arbuscular mycorrhizal fungi, critical loads of nitrogen deposition, and shifts from native to invasive species in a southern California shrubland [PDF]

, 2016
Anthropogenic nitrogen (N) deposition and invasive species are causing declines in global biodiversity, and both factors impact the diversity and functioning of arbuscular mycorrhizal (AM) fungi.

Space between houses influences movement and habitat selection of ungulates: Width as a novel metric of development

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
In rural areas, maintaining spaces between houses >500 m will likely facilitate ungulate movement. To fully conserve functional habitat, such as unimpeded habitat use along migration corridors, maintaining spaces approximately >2.5 km between houses will likely be necessary. Abstract Wildlife often lose access to habitat due to housing development. The

Fuel reduction treatments reduce modeled fire intensity in the sagebrush steppe

Ecosphere, 2022
Increased fire size and frequency coupled with annual grass invasion pose major challenges to sagebrush (Artemisia spp.) ecosystem conservation, which is currently focused on protecting sagebrush community composition and structure. A common strategy for

Seed source climate and precipitation timing determine dryland tree recruitment in hot and dry range margins

Journal of Ecology, Volume 114, Issue 5, May 2026.
Using a common garden study with experimental seasonal precipitation regimes, this study shows that intraspecific phenotypic variation mediates the effect of seasonal drought on Pinus monophylla recruitment, suggesting that different populations may respond uniquely to changes in climate.

Cytotype and local adaptation drive phenotypic variation in two subspecies of big sagebrush (Artemisia tridentata)

Ecosphere
Big sagebrush (Artemisia tridentata) is a widespread and locally dominant shrub throughout many ecosystems in western North America. A. tridentata ssps. tridentata and wyomingensis are two subspecies whose populations occupy the warm‐arid regions of the ...
