Evidence for density-dependent effects on body composition of a large omnivore in a changing Greater Yellowstone Ecosystem

Understanding the density-dependent processes that drive population demography in a changing world is critical in ecology, yet measuring performance–density relationships in long-lived mammalian species demands long-term data, limiting scientists' ability to observe such mechanisms. We tested performance–density relationships for an opportunistic omnivore, grizzly bears (Ursus arctos, Linnaeus, 17

When are environmental DNA early detections of invasive species actionable?

Environmental DNA (eDNA) sampling provides sensitive early detection capabilities for recently introduced taxa. However, natural resource managers struggle with how to integrate eDNA results into an early detection rapid response program because positive eDNA detections are not always indicative of an eventual infestation. We used a structured decision making (SDM) framework to evaluate appropriat

Toward a national eDNA strategy for the United States

Environmental DNA (eDNA) data make it possible to measure and monitor biodiversity at unprecedented resolution and scale. As use-cases multiply and scientific consensus grows regarding the value of eDNA analysis, public agencies have an opportunity to decide how and where eDNA data fit into their mandates. Within the United States, many federal and state agencies are individually using eDNA data i

Using Pollinator Environmental DNA to Assess the Ecological Resilience of America’s Grasslands

Scientists from six USGS science centers are collaborating with USDA, university, and Tribal partners, and Department of the Interior land managers, to assess the status of pollinator communities and the distribution of species of conservation concern using environmental DNA. These methods will be used to improve assessments of habitat quality and pollinator responses to restoration, including...

USGS research on the effects of renewable energy on wildlife

Renewable energy development, such as solar and wind energy, is growing in the United States and is expected to continue expanding for the foreseeable future. However, renewable energy infrastructure can be a risk to some wildlife including threatened and endangered species. Wildlife managers and energy developers need wildlife risks to be assessed and effective strategies to mitigate those risks...
