This data release includes data and metadata used in the estimation of Ceratocystis lukuohia survival in ambrosia beetle frass under various temperature and humidity conditions on Hawaiʻi Island. Data were used in the analysis of the manuscript, "Ceratocystis lukuohia-infested ambrosia beetle frass as inoculum for Ceratocystis wilt of Metrosideros polymorpha." Frass was exposed at two locations including Volcano and Hilo, as well as a control incubator and frass was tested for viable C. lukuohia propagules through a carrot baiting technique over time.
This data release includes data and metadata on 1) avian diet 2) seed rain 3) understory plant composition 4) seedling abundance and 5) sampling locations for these sites. In addition it includes data on seedling abundance, grass cover and light levels for a grass removal/seed addition experiment . All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. This study looked at multiple biotic interactions that potentially lead to self-reinforcing feedbacks within intact forest and degraded forest sites. This data in particular quantifies natural seedling regeneration in our sites, and the cover of different substrates and vegetation in the immediate area of these seedlings.

Multi-species recovery planning can be a challenging natural resource management task. In collaboration with state and federal agencies, and botanical and technical experts, we developed and tested a multi-step optimization process to assist in identifying the minimum climate resilient habitat for the recovery of multiple threatened, endangered, and at-risk plant species across east Maui. The dataset presented here includes all metrics used to consider selection of units for the spatial optimization.
This data release includes metadata and tabular data that documents initial water conditions (temperature, pH, dissolved oxygen and salinity) during an aquarium-based pilot study aimed to determine the survival of fish exposed to carbon dioxide (CO2) gas treatment. These results were used as a basis for conducting a larger aquarium study aimed to test the efficacy of CO2 as a tool for managing invasive fish in anchialine pools.
As part of a larger study on the efficacy of the biopesticide VectoMax FG for control of larval Culex quinquefasciatus and adult mosquito traps for monitoring, USGS personnel evaluated host-seeking trap configurations and attractants as well as infusions for gravid trap for capturing adult mosquitoes (Culex quinquefasciatus and Aedes japonicus) in native forest habitat from August to November 2017. Four trap sites were selected in a forest tract in Volcano Village. Traps were arranged in a 100-meter square and trap types and lures were rotated through each site during each week of the study in a latin square design. Both host-seeking traps (Biogents Sentinel Traps and Centers for Disease Control and Prevention (CDC)...

The Hawaii Forest Bird Survey (HFBS) systematically characterized plant and bird communities across transects spanning all major Hawaiian Islands except O‘ahu. This extensive dataset has now been organized into a database and associated geographic information system (GIS) layers. This baseline provides an opportunity to assess how forest ecosystems and their constituent bird and plant populations have changed over time. As part of the HaBiTATS (Hawaiian Biodiversity Trends Across Time and Space) project, a select area on Hawai‘i Island was surveyed in 2015 with the objective of demonstrating the potential of using the HFBS methodology to reassess the status of bird and plant communities across multiple geographic...

Data represent predicted cheatgrass (Bromus tectorum) cover from a quantile regression model. We used quantile regression to model cheatgrass abundance as a function of climate, weather, and disturbance, treating outputs as low to high invasion scenarios.The model was developed using cheatgrass cover data collected by the Bureau of Land Management (BLM) Assessment, Inventory, and Monitoring (AIM) program, paired with covariates representing climate, weather, fire history, and disturbance. Quantile regression estimates different coefficients for each predictor variable at each quantile of interest, allowing a given environmental variable to be more or less important at the high end of the response distribution. The...

Acoustic sampling for occurrence of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) was conducted at 12 locations on U. S. Army facilities on O‘ahu Island, Hawai‘i. Bats were confirmed as present at 10 of these locations: Dillingham Military Reservation, Helemano Military Reservation, Kahuku Training Area, Kawailoa Training Area, Mākua Military Reservation, Schofield Barracks East Range, Schofield Barracks West Range, Schofield Barracks (Mendonca Park Housing), Tripler Army Medical Center, and Wheeler Army Airfield. Our acoustic sampling did not record bat vocalizations at Fort DeRussy or Fort Shafter. Despite the presence of bats at the above 10 locations, foraging activity as identified from characteristic...

Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured at 23 sites on Hawaiʻi Island from May 2018 through August 2021. Radio transmitters were affixed to captured bats and, when possible, radio telemetry was used to locate bats in trees or forest stands used for day-roosts. Repeated visits to confirm bat presence were conducted until radio-tagged bats were no longer detected. Of the total 148 captured bats we affixed 131 with radio transmitters and attempted to relocate 127 (38 female; 89 male; 120 adult; 7 juvenile) on subsequent days of tracking. Radio signals were not detected for 36 bats (6 female; 30 male). Of the 91 bats (32 female; 59 male) relocated, males retained transmitters longer than females...

This data release includes metadata and tabular data that document the responses of birds to changes in habitat conditions before and after koa (Acacia koa) defoliation by koa moths (Scotorythra paludicola). Data sets document changes in the (1) use of tree species, (2) arthropod composition of diets, and (3) body mass.
Habitat use, diet, prey availability and foraging ecology of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus, Vespertilionidae), was examined in the east Maui region inclusive of the Waihou Mitigation Area, Pu‘u Makua Restoration Area and the wind power facility operated by Auwahi Wind Energy, LLC. Research funding was provided by Auwahi Wind Energy, LLC (Auwahi Wind) to fulfill requirements for mitigating bat fatalities under its approved incidental take permit. The study was conducted to inform the mitigation and management requirements of Auwahi Wind Energy. Acoustic monitoring over the three-year period demonstrated that bats are present and actively feed year-round at the Waihou Mitigation Area.
