Assessing vegetation recovery from energy development using a dynamic reference approach
Ecology and Evolution, 2022 Ecologically relevant references are useful for evaluating ecosystem recovery, but references that are temporally static may be less useful when environmental conditions and disturbances are spatially and temporally heterogeneous.

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

Potential for post‐fire recovery of Greater Sage‐grouse habitat
Ecosphere, 2019 In the western United States, fire has become a significant concern in the management of big sagebrush (Artemisia tridentata Nutt.) ecosystems. This is due to large‐scale increases in cover of the fire‐prone invasive annual cheatgrass (Bromus tectorum L.)

PLoS ONE, 2019 Nitrogen additions are known to elicit variable responses in semi-arid ecosystems, with responses increasing with precipitation. The response of semi-arid ecosystems to nitrogen are important to understand due to their large spatial extent worldwide and ...

Resource allocation effects on the timing of reproduction in an avian habitat specialist
Ecosphere, 2021 Variation in nutrient allocation can influence the timing of breeding and ultimately reproductive output. Time and space constraints might exist, however, if fewer food resources are available to meet the costs of reproduction early during the ...

Wildlife Biology, EarlyView.Feared, revered, and politicized, wolves have long captured human imagination, and ignited fierce conservation conflicts. In the United States, the Endangered Species Act protects species at risk of extinction from human impacts. This far‐reaching legislation, which impacts development and state‐level wildlife management, has been fraught with legal ...
