Estimating submersed aquatic vegetation biomass using a hierarchical Bayesian model of ordinal measurements and structural zeros Estimating submersed aquatic vegetation biomass using a hierarchical Bayesian model of ordinal measurements and structural zeros

This study explores the prediction of a continuous target variable that is primarily measured as an ordinal outcome. Interest in such prediction may occur given data from double- or two-phase sampling designs, where an auxiliary variable is measured at all sampling units and a target and predictor variable, X, at a subset of those units. This study focuses on the case where X is...

Restoration of Gavia immer (common loon) in Minnesota—2025 annual report Restoration of Gavia immer (common loon) in Minnesota—2025 annual report

In cooperation with the Minnesota Department of Natural Resources, the U.S. Geological Survey monitored 98 Gavia immer (common loon) focal territories and 43 nonfocal territories in north-central Minnesota in 2025. Focal territories are those sampling units from which study inferences can be made. Nonfocal territories were adjacent to focal territories and were observed to monitor common...

Rapid Genetic Testing to Identify New World Screwworm

Early detection and rapid response are critical to controlling the spread of New World Screwworm, a blowfly pest that has re-emerged in the U.S. As the USDA leads the federal response, USGS Ecosystems Mission Area scientists are developing and validating a rapid DNA field test that can be used onsite with simple materials and basic training to support surveillance and response efforts.

Improving hydroacoustic techniques to assess invasive carp populations in large rivers

Invasive carp, such as Bighead Carp and Silver Carp, are non-native fish that have been introduced throughout North American waterways, often through human activities. Their ability to rapidly reproduce, outcompeting native fish for food and habitat, can pose a significant threat to local ecosystems. Additionally, their large population numbers can harm commercial and recreational fishing, causing...

Riverine Acoustic Fish Telemetry (RAFT) Network

The Riverine Acoustic Fish Telemetry (RAFT™) Network is a node of the Ocean Tracking Network (OTN) and serves as a repository to access and archive acoustic fish telemetry data from projects occurring across the Mississippi River Basin. By sharing the locations of receivers and detections of member transmitters across all receivers in the Network, RAFT provides an avenue for collaboration and...
