A comparison and development of methods for estimating shrub volume using drone‐imagery‐derived point clouds

Ecosphere
Shrub volume is used to calculate numerous, essential ecological indicators in rangeland ecosystems such as biomass, fuel loading, wildlife habitat, site productivity, and ecosystem structure.

Occupancy and abundance of predator and prey: implications of the fire‐cheatgrass cycle in sagebrush ecosystems

Ecosphere, 2016
Sagebrush (Artemisia tridentata) ecosystems are declining due to biological invasions and changes in fire regimes. Understanding how ecosystem changes influence functionally important animals such as ecosystem engineers is essential to conserve ...

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.)

Growth and age dynamics of juvenile plants of a dominant shrub in North American drylands

Ecosphere
Long‐lived perennial species in drylands tolerate a range of environmental conditions over their lifespan, but young plants are more vulnerable to stressful conditions than mature plants.

The potential of novel native plant materials for the restoration of novel ecosystems

Elementa: Science of the Anthropocene, 2015
Extensive ecological change has been sustained by many dryland ecosystems throughout the world, resulting in conversion to so-called novel ecosystems. It is within such ecological contexts that native plant materials destined for ecological applications ...

Weather and leaf age separately contribute to temporal shifts in phyllosphere fungal community structure in sagebrush

Ecosphere
Microbial communities living on plant leaves can positively or negatively influence plant health and, by extension, can impact whole ecosystems. Most research into the leaf microbiome consists of snapshots, and little is known about how microbial ...

Ecosystem resilience is evident 17 years after fire in Wyoming big sagebrush ecosystems

Ecosphere, 2016
Recent policy has focused on prevention of wildfire in the sagebrush steppe in an effort to protect habitat for the greater sage grouse (Centrocercus urophasianus).

Above‐ and belowground microenvironmental attributes cluster to varying degrees around Wyoming big sagebrush canopies

Ecosphere
Microsites beneath shrub canopies in dryland landscapes characterized by a mosaic of bare ground and patchy vegetation are often considered critical for the establishment of understory species.

Evaluation of a drone to map and monitor critical habitat features for the Sage Thrasher (Oreoscoptes montanus)

Drone Systems and Applications
Habitat destruction is the leading cause of global biodiversity loss. To recover endangered species requires knowing the habitat elements that are essential to their survival, defined as critical habitat.
