Cumulative effects of an herbivorous ecosystem engineer in a heterogeneous landscape

Ecosphere, 2016
Foraging by herbivores alters individual plants and vegetation communities directly, and engineering behaviors such as bioturbation (digging and turning soil) and biodeposition (deposition of feces and urine) can affect soils and physical properties that

Integrating herbicide application and seeding techniques to restore native plant diversity in crested wheatgrass‐dominated rangelands

Restoration Ecology, EarlyView.
Abstract Introduction Restoring native plant diversity in crested wheatgrass (Agropyron cristatum)‐dominated rangelands is a persistent challenge in ecological restoration across western North America. Dense, long‐lived stands of this exotic grass suppress native seedling recruitment, hinder habitat restoration, and reduce ecosystem resilience ...

Surface fluxes and water balance of spatially varying vegetation within a small mountainous headwater catchment [PDF]

Hydrology and Earth System Sciences, 2010
Precipitation variability and complex topography often create a mosaic of vegetation communities in mountainous headwater catchments, creating a challenge for measuring and interpreting energy and mass fluxes.

Differential Preference of Wintering Mule Deer for Accessions of Big Sagebrush and for Black Sagebrush [PDF]

Journal of Range Management, 1981
Free-roaming mule deer showed significant differential preference for accessions of big sagebrush (Artemisia tridentata) grown in a uniform garden. Mule deer also selectively preferred certain accessions of black sagebrush (A. nova). The role of monoterpenoids (essential or volatile oils) in determining preference among accessions and taxa of Artemisia-

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Relative abundance of and composition within fungal orders differ between cheatgrass (Bromus tectorum) and sagebrush (Artemisia tridentate)-associated soils.

PLoS ONE, 2015
Nonnative Bromus tectorum (cheatgrass) is decimating sagebrush steppe, one of the largest ecosystems in the Western United States, and is causing regional-scale shifts in the predominant plant-fungal interactions.

Landscape conservation forecasting to evaluate ecological condition and wildlife habitat suitability in eastern Nevada U.S.A.

Restoration Ecology, EarlyView.
Abstract Introduction Cooperation among managers of protected areas and federal multiple use lands with private inholdings to increase restoration success and economies of scale creates ecological and regulatory complexity best studied with state‐and‐transition simulation models (STSM).

Integrating Ecosystem Resilience and Resistance Into Decision Support Tools for Multi-Scale Population Management of a Sagebrush Indicator Species

Frontiers in Ecology and Evolution, 2020
Imperiled sagebrush (Artemisia spp.) ecosystems of western North America are experiencing unprecedented conservation planning efforts. Advances in decision-support tools operationalize concepts of ecosystem resilience by quantitatively linking spatially ...

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 ...
