Data

This data release contains a CSV dataset of the likelihood of sapling recruitment based on abundance of seedlings height classes and other stand and site-level factors. Maps accompany the CSV on how the relationship between temperature and relative survival and seedling/sapling abundance varies by size class for ten tree species in the northeastern and midwestern USA, and can be used to...

The Coquí Llanero (Eleutherodactylus juanariveroi) is one of twelve remaining species of Eleutherodactylus frogs endemic to Puerto Rico. They are known only from three isolated populations separated from each other by ~30 km: Caño Tiburones, Arecibo; Sabana Seca, Toa Baja, and Carolina. These frogs are cultural icons and hold prominent roles in the energy flow of the island’s tropical...

Acoustic Telemetry is gaining popularity for use in fisheries research as a method to estimate survival and observe behaviors of native fish species. Methodology for capture and tagging of fish is typically context and species-specific, requiring a case by case basis for best practices to maximize survival of tagged individuals. This dataset includes acoustic detection data from 320...

This data release contains acoustic Doppler current profiler (ADCP) data collected in 2023 from two uplooking tripods in bays of Lake Ontario in Central New York. Data were collected at Irondequoit Bay (USGS station number 431314077315901) and at Sodus Bay (USGS station number 431533076582101). Data are organized by bay in child item datasets containing the raw binary data files from the...

Dataset includes the number of shortnose sturgeon that were detected via acoustic telemetry and side-scan sonar in the Hudson River on a series of survey dates from 2021 to 2023.

A study was conducted in the Yakima River Basin in Washington state to evaluate behavior of juvenile Chinook salmon and Coho salmon upstream of Tieton Dam from April to November 2024. The goal of this study was to collect data useful for designing and siting downstream fish passage options at the dam. Under current operations, water is passed through the dam via a deep intake located on...

Federally-threatened ago-0 spring Chinook salmon (Oncorhynchus tshawytscha) were acoustic tagged and released near Lookout Point Reservoir to estimate passage and survival during the second year of an experimental reservoir drawdown operation that was designed to facilitate downstream passage through two reservoirs and dams. The experimental operation consisted of lowering the water...

Juvenile Chinook salmon (age 0 and age 1), steelhead, and sockeye salmon were tagged with acoustic transmitters and released at sites along the Yakima River in and below Yakima, WA from 2018 to 2024. Detection sites varied across years but included arrays placed at diversion dams, canals, hydropower facilities, and other locations throughout the Yakima and Columbia rivers. Study design...

Three studies were conducted in Shasta Reservoir in California to evaluate downstream migration and behavior of juvenile late-fall run Chinook salmon (Oncorhynchus tshawutscha) released in the McCloud River upstream of Shasta Dam in Spring 2017, Fall 2017, and Fall 2024. The goal of this study was to collect data beneficial for citing a juvenile salmon collection system for downstream...

Acoustic telemetry is an effective tool for the study of fish survivorship and habitat use. Fish are tagged with acoustic tags and presence data is collected with stationary receivers. This data set contains a total of 69 hatchery tagged juvenile Lake Sturgeon released into the Genesee River, NY in the Fall of 2019 and 2020, along with data for 30 sub-adult Lake Sturgeon field tagged in...

The active channel of the Willamette River in western Oregon is the portion of the floodplain that regularly conveys water and bed-material sediment (typically sand and gravel) on an annual basis (Wallick and others, 2013). The active channel comprises features such as gravel bars, side channels, main channel and alcoves that contribute to the overall diversity of aquatic and floodplain...

This dataset represents coarse active relocations of acoustic transmitters in telemetry tagged fish of various species detected among the Mississippi and Missouri rivers near their confluence. These detections of unknown tagged individuals were incidental and occur within the range and frequency of effort for a focused active telemetry study on invasive carp. These river segments consist...
