Hawaii Island forest bird movement data from 2014 to 2019 Hawaii Island forest bird movement data from 2014 to 2019
This data release includes data and metadata containing estimated and predicted locations of radio telemetered Hawaiian forest birds. Radio telemetry data was collected using an automated radio telemetry network from 2014 to 2019 from birds in two study sites, one a continuous forest and the other a fragmented forest. Four bird species that varied in age and sex were studied: the...

This release includes data and metadata (1-2) documenting visitation of ambrosia beetles (Coleoptera: Curculionidae) to healthy ʻōhiʻa (Metrosideros polymorpha) trees in two separate experiments, (3) geographical location and details of the trees used in the experiments, (4) culture of the fungal pathogens Ceratocystis lukuohia and Ceratocystis huliohia from naturally and experimentally...
Hawaiian hoary bat population genetics 1988 to 2020 Hawaiian hoary bat population genetics 1988 to 2020
Genetic diversity levels, effective population size estimates, and population structure of the endangered Hawaiian hoary bat (Lasiurus semotus, also known as Aeorestes semotus) were examined across the islands of Hawai‘i, Maui, O‘ahu, and Kaua‘i using eighteen nuclear microsatellite loci and one mitochondrial gene from 339 individuals collected between 1988 and 2020. The study extracted...
Kaloko-Honokohau National Historical Park Orangeblack Hawaiian damselfly data, 2016-2017 Kaloko-Honokohau National Historical Park Orangeblack Hawaiian damselfly data, 2016-2017
This data release includes metadata and tabular data that documents the endangered orangeblack Hawaiian damselfly (Megalagrion xanthomelas) at Kaloko-Honokohau National Historical Park during 2016-2017. Data sets document (1) numbers of damselflies observed during surveys, (2) habitat characteristics of anchialine pools at which damselflies were surveyed, (3) substrates on which female...
Samoan swallowtail butterfly reproductive response to host plant characteristics, 2013-2014 (ver. 2.0, July 2024) Samoan swallowtail butterfly reproductive response to host plant characteristics, 2013-2014 (ver. 2.0, July 2024)
Surveys for immature life stages of the Samoan swallowtail butterfly (Papilio godeffroyi) were conducted on 117 individually marked host trees (Micromelum minutum) in eight forest stands on Tutuila Island, American Samoa, at approximately monthly intervals during 2013-2014. The eight stands were mostly in or adjacent to the National Park of American Samoa (NPSA), but one stand was...
Selected streamgage sites and periods of record for consideration of flood-generating mechanisms in Hawai`i and Southeast Alaska, 1913-2022 Selected streamgage sites and periods of record for consideration of flood-generating mechanisms in Hawai`i and Southeast Alaska, 1913-2022
This data release consists of a comma-delimited ascii file with attributes for 21 U.S. Geological Survey streamgage sites in Hawai`i and Southeast Alaska selected to enable assessment of how floods might change in a future climate. Floods in Hawai`i and Southeast Alaska have led to loss of human life; damage to agricultural crops, cultural and biological resources, infrastructure, and...
SUTRA model used to evaluate long-term groundwater availability in the Waihee, Iao, and Waikapu aquifer systems, Maui, Hawaii SUTRA model used to evaluate long-term groundwater availability in the Waihee, Iao, and Waikapu aquifer systems, Maui, Hawaii
Groundwater levels have declined since the 1940s in the Wailuku area of central Maui, Hawaii, on the eastern flank of West Maui volcano, mainly in response to increased groundwater withdrawals. Available data since the 1980s also indicate a thinning of the freshwater lens and an increase in chloride concentrations of pumped water from production wells. These trends, combined with...
Hawaiʻi Island Survival of Ceratocystis in Frass 2019-2020 Hawaiʻi Island Survival of Ceratocystis in Frass 2019-2020
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...
Great Basin predicted potential cheatgrass abundance, with model estimation and validation data from 2011-2019 Great Basin predicted potential cheatgrass abundance, with model estimation and validation data from 2011-2019
This data release includes data and metadata describing 1) the rule set used to create vegetation type categories for the Great Basin; 2) estimation and validation data used to fit models of cheatgrass (Bromus tectorum) cover; and 3) mapped predictions of potential cheatgrass abundance.
Hawaii Volcanoes National Park, Puhimau Geothermal Area vegetation and abiotic data, 2011-2021 Hawaii Volcanoes National Park, Puhimau Geothermal Area vegetation and abiotic data, 2011-2021
This data release includes metadata and tabular data that documents survival of endangered Portulaca sclerocarpa, percent cover of vegetation surrounding Portulaca sclerocarpa, as well as soil depth and soil temperature. All data were taken between 2011-2021 in the Puhimau Geothermal Area in Hawaiʻi Volcanoes National Park.
Hawaiian Islands downscaled climate projections for baseline (1983-2012), mid- (2040-2059), and late-century (2060-2079) scenarios Hawaiian Islands downscaled climate projections for baseline (1983-2012), mid- (2040-2059), and late-century (2060-2079) scenarios
Global downscaled projections are now some of the most widely used climate datasets in the world, however, they are rarely examined for representativeness of local climate or the plausibility of their projected changes. Here we apply steps to improve the utility of two such global datasets (CHELSA and WorldClim2) to provide credible climate scenarios for climate change impact studies in...
Hawaiian Islands bioclimatic variables for baseline and future climate scenarios Hawaiian Islands bioclimatic variables for baseline and future climate scenarios
We integrated recent climate model projections developed for the State of Hawai’i with current climatological datasets to generate updated regionally defined bioclimatic variables. We derived updated bioclimatic variables from new projections of baseline and future monthly minimum, mean, and maximum temperature (Tmin, Tmean, Tmax) and mean precipitation (Pmean) data at 250 m resolution...
