Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

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

Microbial Endolithic Community at Meteor Crater

Meteoritics &Planetary Science, EarlyView.
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

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-

Herbicide protection seed coating technology for improving restoration success in Great Basin sagebrush plant communities

Restoration Ecology, EarlyView.
Abstract Introduction Invasive annual grasses (IAGs) pose a significant threat to sagebrush rangelands, but restoring native perennial species using seed is challenging because pre‐emergent herbicides, used to control IAGs, also harm desired seedlings. This necessitates seeding after herbicide effects diminish. Objective This collection of three papers

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.

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.

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 ...
