Long-term environmental management to prevent waterfowl population declines is informed by ecology, movement behavior and habitat use patterns. Extrinsic factors such as human-induced disturbance can cause behavioral changes which may influence movement, and resource needs, driving variation that affects management efficacy. To better understand the relationship between human-based disturbance and animal movement and habitat use, and their potential effects on management, we GPS tracked 15 dabbling ducks in California over about 4-weeks before, during and after the start of a recreational hunting season in October and November 2018. We recorded locations at 2-minute intervals across three separate 24-hour tracking...

In this data set, records (rows) represent GPS locations of ducks marked with telemetry in California and whether locations were overlapping (within 300 m of) locations of marked ducks in other consecutive years (2015-16, 2016-17, and 2017-18) during October - March. Years 2015-16, 2016-17, and 2017-18 represented drought, non-drought, and non-drought, respectively. Matchett and company (2020; see Larger Work section for citation) summarized this data set in tables E3 and E4 to compare overlap of duck locations between consecutive years to investigate interannual habitat stability in relationship with drought, habitat management (daytime roosts and night feeding sites), and in two regions (Suisun Marsh and California...

Zoonotic diseases are of considerable concern to the human population and viruses such as avian influenza (AIV) threaten food security, wildlife conservation and human health. Wild waterfowl and the natural wetlands they use, are known AIV reservoirs, with birds capable of virus transmission to domestic poultry populations. While infection risk models have linked migration routes and AIV outbreaks, there is a limited understanding of wild waterfowl presence on commercial livestock facilities, and movement patterns linked to natural wetlands. In this dataset, records (rows) represent all analyzed locations of individual waterfowl relative to locations of commercial livestock facilities and habitats. Each row has...

The Underwater Acoustic Deterrent System is an experimental deterrent that utilizes underwater sounds to deter invasive carps. An experimental deployment and evaluation of a UADS is currently being conducted at Lock 19 on the Mississippi River, near Keokuk, Iowa. This dataset includes information derived from two telemetry arrays (i.e., 307 kHz HTI and 69 kHz VEMCO) deployed at and around Lock 19 to evaluate fish movement and response to the UADS in 2021 and 2022. Silver Carp, Bighead Carp, Grass Carp, and a variety of native fish species were tagged and monitored with the telemetry arrays. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
Combined telemetry locations for sage grouse in Mono County which were fitted with radio-transmitters for the USGS Greater sage-grouse project. Contains spatial and temporal information as well as topography, estimated habitat types, elevation, slope, etc. Dataset is complete for all birds from January 2003 to November 2005. Accuracy of individual data fields currently being verified, spatial and temporal accuracy has however, been verified.
Studies utilizing Global Positioning System (GPS) telemetry rarely result in 100% fix success rates (FSR). Many assessments of wildlife resource use do not account for missing data, either assuming data loss is random or because a lack of practical treatment for systematic data loss. Several studies have explored how the environment, technological features, and animal behavior influence rates of missing data in GPS telemetry, but previous spatially explicit models developed to correct for sampling bias have been specified to small study areas, on a small range of data loss, or to be species-specific, limiting their general utility. Here we explore environmental effects on GPS fix acquisition rates across a wide...
This dataset contains a select subset of Argos and GPS locations collected by satellite data collection systems from collared adult female polar bears that were instrumented in the southern Beaufort Sea between 1985-2015.

These data are comprised of measurements of elements (i.e., aluminum, iron, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic, selenium, cadmium, tin, antimony, barium, thallium, lead, mercury, sodium, magnesium, potassium, calcium, manganese, and strontium) in Kemp's ridley sea turtle (Lepidochelys kempii) egg contents. The eggs were collected along the Texas Gulf coast in 2010-2013; only eggs that failed to hatch were retained for analyses. All results are provided on a dry-weight basis in units of mg/kg.
This dataset includes information derived from a Vemco telemetry array located at Lock and Dam 19 on the Mississippi River near Keokuk, IA. Ten fish species, comprised of both native and invasive species, were detected with this system. Lock Queue Reports, which detail the daily lock operation for river traffic, were obtained from the U.S. Army Corps of Engineers. Temperature data were recorded on the Vemco receivers and stage height data were obtained from the U.S. Army Corps of Engineers. Six worksheets are included in this file, including a meta-data sheet that describes the datasets, provides variable names, and associated units of measure.

Understanding how routing modifications influence survival of juvenile salmon is complex because reach-specific survival and routing at key river junctions in the North Delta each have a different relationship with river flow. Therefore, to facilitate understanding of how routing modifications at key river junctions influence through-Delta survival, we developed this spreadsheet model to allow managers to explore the potential effects of modifying routing. The purpose is to provide a screening tool that allows managers to quickly run many different scenarios to understand how both routing and route-specific survival interact to affect overall survival through the Delta. This tool may be useful in narrowing the range...
Hawaiian hoary bats (Lasiurus cinereus semotus) on Hawaii island were surveyed intermittently from 2004–2010. This data release is a single table of resulting bat location estimates, including date, time, coordinates for each location, and presumed bat activity at the time of collection. Nightly movements were documented for 30 Hawaiian hoary bats along the windward (eastern) side of the island of Hawaii. Each bat was fitted with a colored, split ring forearm band (Size X3; A. C. Hughes, Hampton Hill, United Kingdom) for long-term individual recognition and with a radiotransmitter (BD-2C model from Holohil Systems, Carp, Ontario, Canada). Bats were then released at the point of capture. Output from the transmitters...
To effectively manage species and habitats at multiple scales, land managers require rapid information on wildlife use of managed areas and responses to landscape conditions and management actions. Global positioning system (GPS) tracking studies of wildlife are particularly informative to species ecology, habitat use, and conservation. Combining GPS data with administrative data, would more comprehensively inform how animals interact with and utilize habitats and ecosystems. Our goal was to create a conceptual model for a system that would accomplish this – the ‘Automated Interactive Monitoring System (AIMS) for Wildlife’. Our first objective was to develop a Customized Wildlife Report (CWR) - the first AIMS for...
Data sets collected for manatee movement and habitat research in the Northern Gulf of Mexico from 2013-2019. These include manatee GPS tracking, manatee sightings, aquatic vegetation from manatee use areas, and environmental data (salinity and bathymetry at vegetation sampling sites).
‘Ōpe‘ape‘a (Hawaiian hoary bats; Lasiurus semotus) were surveyed at 23 sites on Hawaiʻi Island from 33 to 2,341 m elevation from May 2018 to August 2021. Of the 23 sites, 8 were established as fixed survey sites for sampling at repeated intervals from January 2019 through January 2021. We surveyed each fixed site at least once per four-month period (January–April, May–August, September–December), with a survey comprising one to three netting events. Additional opportunistic surveys were conducted at alternate sites or on alternate dates. We captured 138 unique bats (37 female, 101 male) and recaptured 10 bats over 224 mist-netting events. Of the total 148 captured bats we affixed 131 with radio transmitters and...
This dataset contains tracking durations for several species of sea turtles tagged with satellite tags between 2008 and 2019. It contains information on species, turtle size, capture methods, tag type, how many days each tag transmitted, whether or not the tag was still attached upon recapture, fouling 'status' of the tag, and foraging region. This dataset thus allows estimation of tracking durations for four species of marine turtles tagged in different study sites in the Gulf of Mexico and Caribbean.
These data show the placement of acoustic telemetry receivers in Yellowstone Lake between 2011 and 2015. Receivers were placed in the lake to record fish movement throught the year. This data release shows the coordinates, timing, and receiver ID for each for each receiver deployment.
