New National-Scale Spatial Maps of Tree-Based Nitrogen Fixation

Symbiotic nitrogen-fixing trees influence soil fertility and provide a large background source of nitrogen in watersheds.

Movements and Habitat Use of Loons for Assessment of Conservation Buffer Zones in the Arctic Coastal Plain of Northern Alaska

Few data exist to assess the value of National Petroleum Reserve-Alaska management buffer zones for conservation-reliant yellow-billed loons or sympatrically breeding red-throated and Pacific loons.

Feeding Ecology Drives Lead Exposure of Facultative and Obligate Avian Scavengers in the Eastern United States

Many lead exposure studies of scavenging birds have focused on individual species. However, studying multiple species with similar, but not identical, feeding behaviors can provide insights into how an animal’s ecology determines its lead exposure.

Reptiles Under the Conservation Umbrella of the Greater Sage-Grouse

Management actions for umbrella species may also benefit co‐occurring species. An understanding of how sage-grouse conservation might benefit non‐target species, such as reptiles, is limited.

The Lead Lining of Agriculture-Related Subsidies for Golden Eagles

Avian scavengers, including golden eagles, often eat animals culled though recreational hunting and pest shooting on agricultural lands.

Evaluating Contributions of Recent Tracking-Based Animal Movement Ecology to Conservation Management

Tracking animals using sensors and bio-telemetry yields important ecological, physiological, and evolutionary insights. However, applied studies of animal movement ecology are lacking, especially in the challenging field of human-wildlife interactions.

Examination of Surveys to Measure Renewable Energy Effects on Birds and Bats

Although renewable energy facilities are often required to complete wildlife surveys before and after constructing facilities, there is a lack of published studies that have closely examined the types of surveys and whether they are comparable within and across facilities.

Response of Biocrust to Fuel Reduction Treatments

In the sagebrush steppe, land managers use fuel reduction treatments to minimize large fire risk. Although biocrusts are associated with reduced cover of fire-promoting, invasive grasses, the impact of fuel reduction treatments on biocrusts is poorly understood.

Frequent Fire Reduces Deep Soil Carbon

Fire activity is changing worldwide, with unclear effects on ecosystem carbon storage. Fire effects on carbon storage are better known for vegetation than for soil, and fire effects on deep soil carbon are especially uncertain.

Excluding Grazing has Positive Effects on Riparian Vegetation, Migratory Birds

Livestock grazing can degrade riparian vegetation, altering habitat for many species of declining migratory breeding birds. At Hart Mountain National Antelope Refuge in southeastern Oregon, cattle were removed from riparian areas in 1990 after 120 years of grazing.

Weed-Suppressive Bacteria Did Not Control Bromus tectorum

Recent trials using a bacterial bioherbicide known as D7 have had mixed results in controlling invasive annual grasses in rangelands.

Components and Predictors of Biocrusts

Although biological soil crusts occur globally in arid and semi-arid environments, the occurrence of biocrusts has not previously been related to individual plant communities at regional scales.
