Six Fathom Bank and Yankee Reef Gillnet and Beam Trawl Data 1991-2022 Six Fathom Bank and Yankee Reef Gillnet and Beam Trawl Data 1991-2022
Annual spring/summer (May-July) and fall (October) gillnet assessment surveys and spring/summer young-of-year (YOY) lake trout beam trawl surveys were conducted by researchers at the USGS Great Lakes Science Center (GLSC) in central Lake Huron on two offshore reefs, Six Fathom Bank and Yankee Reef. The spring/summer and fall gillnet assessment took place between 1991- 2022 and 1991-1998
Wyoming Range fish data 2012-2019 Wyoming Range fish data 2012-2019
The goal of the study associated with this dataset was to characterize flow-ecology relationships for Mottled Sculpin (Cottus bairdii) and Mountain Sucker (Catostomus platyrhynchus) in snowpack driven headwater streams of the Upper Green River Basin in Wyoming, U.S.A. Our objectives were to: 1) evaluate whether variation in Mottled Sculpin and Mountain Sucker abundance is driven by...

Laboratory optical measurements for selected streams in the Clear Lake basin, Lake County, California Laboratory optical measurements for selected streams in the Clear Lake basin, Lake County, California
Clear Lake, situated in the Coast Range west of California's Central Valley, is the largest natural freshwater lake entirely within the state. It consists of three distinct arms: the Upper Arm-a large, open-water area to the northwest; the Lower Arm-a smaller, narrower section to the southeast; and the Oaks Arm-the smallest and narrowest region, located to the east. Water quality in...

Droplet digital PCR data for environmental DNA surveys of Boa imperator in St. Croix, U.S. Virgin Islands, December 2023 and July 2024 Droplet digital PCR data for environmental DNA surveys of Boa imperator in St. Croix, U.S. Virgin Islands, December 2023 and July 2024
Invasive Central American boas (Boa imperator) have established a reproducing population on the western side of St. Croix, U.S. Virgin Islands, as shown by increasing physical capture rates. However, their prevalence throughout the island is largely unknown. The large snakes threaten endemic and endangered species through competition and predation, jeopardizing island biodiversity...
