Outcomes of control and monitoring of a widespread riparian invader (Tamarix spp.): A comparison of synthesis approaches

Effective ecological restoration requires empirical assessment to determine outcomes of projects, but conclusions regarding the effects of restoration treatments on the whole ecosystem remain rare. Control of invasive shrubs and trees in the genus Tamarix and associated riparian restoration in the American Southwest has been of interest to scientists and resource managers for decades; dozens of st

Tracking cycles of Phanerozoic opening and closing of ocean basins using detrital rutile and zircon geochronology and geochemistry

Sedimentary basins provide a deep time archive of tectonic and Earth-surface processes that can be leveraged by detrital mineral U-Pb dating and geochemistry to track paleogeography, magmatism, and crustal evolution. Zircon preserves the long-term (billions of years) record of supercontinent cycles; however, it is biased toward preserving felsic crustal records. Detrital rutile complements the det

Estimating spatial variation in greater sage-grouse lek buffers using seasonal space use models

Greater sage-grouse ( Centrocercus urophasianus ) management relies on the identification and protection of core habitat for the species. Core areas are often centered on leks where the potential impacts of anthropogenic development and other disturbances can be evaluated based on buffer distances around active leks. While buffer distances have been quantified for some regions, sage-grouse space...

A user-friendly decision support tool for monitoring and managing greater sage-grouse populations

Researchers within the U.S. Geological Survey (USGS) and Colorado State University (CSU) developed a hierarchical population monitoring framework for managing greater sage-grouse ( Centrocercus urophasianus ) populations and the sagebrush ecosystems that they depend upon for survival and reproduction. This hierarchical population monitoring strategy now serves as a foundation for future...

Hierarchical Population Monitoring Framework for Greater Sage-Grouse

Greater sage-grouse ( Centrocercus urophasianus ) are at the center of state and national land use policies largely because of their unique life-history traits as an ecological indicator for health of sagebrush ecosystems.
