This Data Release provides imagery data for the development of deep-learning models to recognize individual brook trout (n=435). Images were collected at the Paint Bank State Fish Hatchery (Paint Bank, VA) on August 9, 2021 using a GoPro Hero 9 camera mounted approximately 50 cm above a fish board. The Paint Bank State Fish Hatchery is operated by the Virginia Department of Wildlife Resources.
Demographic look up tables allow the translation of a population growth rate, which is estimable from count data, to a set of vital rates parameterizing the birth and survival processes of the population. These tables are used in the BatTool R package to produce realistic simulations of population abundance trajectories given a range of population growth rates.
This dataset of 40 square kilometer (sq. km) hexagons was created by the U.S. EPA's Environmental Monitoring and Assessment Program (EMAP) and is being released by the U.S. Geological Survey for public use. The 40 sq. km hexagons were derived from a grid consisting of a triangular array of points that cover the United States and neighboring Canada and Mexico. The base grid of points had a companion areal structure called a tessellation. The base tessellation hexagons constituted this tessellation. In other words, surrounding each grid point was a hexagon that defines the area within which all points are closer to this grid point than to any other, and the set of hexagons defined this way completely and -mutually...

The Wyoming statewide time-stamped oil and gas wells shapefile was developed to provide a historical perspective of drilling activity for the Wyoming Landscape Conservation Initiative (WLCI). This product approximates start and stop dates for each well in Wyoming based on database attributes. These data originated from the Wyoming Oil and Gas Conservation Commission (WOGCC). Data represent 120 years of oil and gas drilling (1900 to 2020) and will facilitate a landscape-level approach to integrated science-based assessments, resource management, and land-use decision making. Oil and gas data from WOGCC were used in a dataset previously published by Biewick in 2010 (https://pubs.usgs.gov/ds/625/). This product expands...

Wetland elevation and soil characteristics across Bayou Sauvage National Wildlife Refuge (2020-2021)
The recent completion of the US Army Corps of Engineers (USACE) Hurricane and Storm Damage Risk Reduction System (HSDRRS) for New Orleans has effectively blocked surface water exchange between Bayou Sauvage National Wildlife Refuge (BSNWR) and the surrounding Lake(s) Pontchartrain and Borgne and the Gulf of Mexico to which it was once connected. Monitoring changes in hydrology, water quality, bird habitat variability, and resident waterbird and nekton communities within BSNWR is important to the long-term sustainability of these aquatic resources for use by visitors and aquatic life in these habitats. In particular, landscape and hydrologic modifications from management and restoration projects in southeastern Louisiana...

We collected fleas from black-tailed prairie dogs (Cynomys ludovicianus) on Buffalo Gap National Grassland and Badlands National Park, South Dakota, 2020-2022. We anesthetized trapped prairie dogs (and their fleas) with isoflurane in induction chambers for processing. We combed each individual with a fine-tooth comb for 30 seconds to remove and count fleas. We released all animals, after they were recovered from anesthesia, at the location where they were captured. Total flea counts from individual prairie dogs were considered an index of flea abundance. During 2018-2020, we provided prairie dogs on 21 sites with grain bait, laced with fipronil (0.005% by weight) by placing 1/2 cup or 1/4 cup of grain at each prairie...

This data set contains information on detections of anuran (i.e., frogs and toads) species at six different management areas in the midwestern United States from 2002 to 2012. From 2002 to 2005 anuran communities were surveyed during the day using multiple methods at individual study wetlands—visual encounter surveys, dip net surveys, and calling surveys using multiple observers in most cases. Data are presented from each survey. From 2008 to 2012 amphibian communities were surveyed through detections of vocalizing anurans recorded by automated recording units. Automated recording units recorded five minutes at the top of every hour for the entire field season (typically April through October). Recorder data are...
The dataset and accompanying analysis scripts accompany the article "Bayesian multistate models allow incorporation of spatial dynamics to improve invasive species management". The data are summarized detections from acoustic telemetry receivers (69 KHz) from 353 silver carp (Hypophthalmichthys molitrix) and 170 bighead carp (H. nobilis) surgically implanted with transmitters in the Illinois River, USA. The analysis scripts assess probability of detection, probability of monthly movement between navigation pools on the river, probability of apparent survival, and probability of operable transmitter battery through a Bayesian multistate hidden Markov model.

Individual species often drive habitat restoration action; however, management under this paradigm may negatively affect non-target species. Prioritization frameworks which explicitly consider benefits to target species while minimizing consequences for non-target species may drastically improve management strategies. We examined extents to which conifer removal, an approach frequently implemented to restore sagebrush ecosystems, can be conducted without detrimental effects to conifer-associated species, including the imperiled Pinyon Jay (Gymnorhinus cyanocephalus). Additionally, we predicted abundance responses for multiple species following simulated conifer removal at sites selected to achieve variable management...

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...
This data set provides the simulated results of releasing malaria-resistant Iiwi into existing populations of wild birds on the Island of Hawaii. Resistant birds are released into mid- and high-elevation forests at different densities at 10-year intervals from 2030 to 2070. Populations of both malaria-resistant and susceptible Iiwi are then predicted at 10-year intervals from release until 2100. Predictions are made based on 3 different climate change projections: A1B, RCP4.5, and RCP8.5. The goal of this project is to evaluate the feasibility of creating a successful population of Iiwi when faced with higher malaria infection predicted as a result of climate change. The model results presented here build upon two...
We examined habitat use and foraging activity of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus), as well as nocturnal aerial insect abundance at Kaloko-Honōkohau National Historical Park located in the coastal region of Kailua-Kona, Hawai‘i Island. The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations (KAHO1-KAHO7) between 1 and 10 m above sea level, that operated nightly from November 2013 through February 2015. Nocturnal aerial insect collection occurred in January and April (2 or 3 nights each) and in July and November (1 or 2 nights each) in 2014. Insects were collected...
The Hawaiian hoary bat (Lasiurus cinereus semotus), a federally and state listed endangered subspecies, is the only extant native terrestrial mammal in the Hawaiian archipelago. It is an insectivorous, solitary and foliage-roosting species that generally roosts alone or in mother-pup family groups. This data release consists of three tabular datasets comprising acoustic and thermal video data of Hawaiian hoary bat behavior at wind turbines. One dataset consists of the acoustic and video detections of bats tabulated by night and turbine, and associated weather and turbine operational data used in analyses. The other two datasets consist of the individual detections, catalogued separately for the acoustic and video...

The newly identified rapid ‘ohi‘a death (ROD; Metrosideros polymorpha) originated in the lower Puna district and its distribution has spread across Hawai‘i Island. As ROD expands it is expected that the loss of the dominant tree species will adversely affect bird populations. This project is a first attempt to describe the relationship between the impacts of ROD on the Hawaiian avifauna, especially the native Hawai‘i ‘amakihi (Hemignathus virens virens) an omnivore found in a wide range of native and nonnative habitat types. ‘Amakihi was generally rare below about 1,300 m elevation (Scott et al. 1986, Reynolds et al. 2003) but recent surveys found that the species is resident and breeding in native-dominated ‘ohi‘a...
