Microsite selection improves post‐fire restoration of singleleaf pinyon pine on Washoe Tribal lands in the Pine Nut Mountains, NV, USA

Restoration Ecology, EarlyView.
Abstract Introduction Singleleaf pinyon pine (Pinus monophylla) holds both ecological and cultural significance for Indigenous Tribes of the Great Basin, such as the Washoe Tribe of Nevada and California. Recent wildfires on Washoe Tribal lands have resulted in the loss of important pinyon pine groves, prompting collaborative efforts to develop post ...

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

Addressing multiple management goals during roadside restoration: reducing weed invasion and fire risk while enhancing native plants and pollinator habitat in semiarid, invaded grasslands

Restoration Ecology, EarlyView.
Abstract Introduction Roadside vegetation management efforts often target a single desirable outcome; however, we frequently have multiple management goals for restoration. Multiple goals may be achieved concurrently, but the efficacy of roadside revegetation methods is largely unclear, especially when multiple methods are combined.

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 ...

Warming reduces the quality of forage resources in a Colorado meadow ecosystem

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Rangelands provide ecosystem services that support approximately 30% of the human population. To maintain sustainable forage resources for animals in grasslands, it is essential to manage grazing pressures by adapting to changes in the quantity and nutritional quality of vegetation affected by climate change and subsequent shifts in plant ...

Trajectories and drivers of compositional and functional variation in sagebrush steppe restoration

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Restoration success is often challenged by unpredictable and undesirable outcomes, especially in arid systems like the sagebrush steppe. In an 11‐year study in Grand Teton National Park, climatic conditions during establishment and local soil texture drove long‐term differences in plant community composition and functional traits.

The Heritability of Migration Behaviors in a Wide‐Ranging Ungulate

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Despite our understanding that variation in migration behavior has both genetic and environmental components, studies quantifying the sources of genetic variation contributing to migration phenotypes are lacking. Our study provides, to our knowledge, the first empirical evidence of heritability in migration behavior in ungulates.

Studies on the microbial populations of the rhizosphere of big sagebrush (Artemisia tridentata)

Journal of Industrial Microbiology & Biotechnology, 2004
Prolonged use of broad-spectrum antibiotics has led to the emergence of drug-resistant pathogens, both in medicine and in agriculture. New threats such as biological warfare have increased the need for novel and efficacious antimicrobial agents. Natural habitats not previously examined as sources of novel antibiotic-producing microorganisms still exist.

Spatial and ecological variation in dryland ecohydrological responses to climate change: implications for management

Ecosphere, 2016
Ecohydrological responses to climate change will exhibit spatial variability and understanding the spatial pattern of ecological impacts is critical from a land management perspective.

Nutritional and reproductive dynamics of moose near their southern range limit

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Though southern moose (Alces alces) had relatively low seasonal fluctuations in body fat, their condition was positively associated with pregnancy and adult survival but did not influence recruitment of young. We demonstrated clear signs of nutritional limitation and unexpected patterns of reproductive performance that may be unique to moose living at ...
