This dataset contains detection-nondetection data for territorial pairs of Golden Eagles at survey sites randomly selected from a grid of equal-sized (13.9 km2) hexagonal sample cells overlaid across the region of interest in Coastal Southern California during 2016 and 2017. We partitioned surveys within seasons based on approximate transition dates for stages in the breeding cycle of...

To assess the effects of rotenone (fish toxicant) treatment and possible fish removal effects on nesting Osprey (Pandion haliaetus) populations, nests were observed at two reservoirs east of Ashland, Oregon. Hyatt Reservoir was treated with rotenone on October 12, 1989. Howard Prairie was observed as an untreated reference area. Nests at both reservoirs were observed two years pre...

This product is a media player application and user guide. The application generates set-interval and random-interval media play schedules. When the application is used to execute the play schedule, it creates its own metadata documentation. The Carp Media Player documents the intended play schedule, generates a real-time log of the media played, and documents if there were any...

Executing the Dwell Time analysis condenses receiver/tag records into readable records of fish movement and receiver effectiveness. Fish movement is described by a temporal sequence of receiver/tag events (durations), where a tag is visible to a specific receiver or collection of receivers. The number and frequency of contacts within a receiver/tag event are summarized by the analysis. A...

This ArcGIS Add-In tool assigns telemetry receivers a “river address,” with the National Hydrography Dataset (NHD) flowlines providing the river name (analogous to a street name in a postal address) and a distance along flowline (the house number in a postal address). Using this information, it is possible to sequence receivers along a flowline. Once sequenced, receiver data can then be...

This study builds upon work conducted under the Great Lakes Fishery Commission (GLFC) Technical Assistance Program that was funded to prepare and evaluate an alternative solid formulation of the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) in a laboratory flume. The project aligns within the lampricide theme in the Sea Lamprey Research Program by improving lampricide performance...

These datasets (e.g., 'Starved Rock fish clearing_multi-beam imaging sonar fish data_Pre-clearing_Sonar-s1.csv') include exported information (e.g., fish detection counts) from processed fixed-location multi-beam imaging sonar and mobile side-scan sonar data. Fish abundance in the navigation lock was determined using mobile side-scan surveys, while multi-beam imaging sonars were used to...

Migratory species often provide ecosystem service benefits to people in one country while receiving habitat support in other countries. The multinational cooperation necessary to ensure continued provisioning of these benefits by migrational processes may be informed by understanding the benefits that people in different countries derive from migratory wildlife. We conducted stated...

Using high-resolution sonar technologies with geographic information systems (GIS) and object based image analysis, benthic characteristics of the Illinois River have been interpreted to support Asian carp research, monitoring, and control. The study plan consisted of data collection and analysis of the Brandon, Dresden, Starved Rock, Marseilles, Peoria, La Grange, and Alton reaches of...

This dataset contains digitized groundwater quality data from 435 wells that are screened in the Chicot aquifer system. Reported values of interest included specific conductance, total dissolved solids, and chloride (Cl) concentration; other parameters and major/trace element concentrations were included if reported. Values listed as "NA" or "-9999" represent data that was not reported...
