Samoan swallowtail butterfly reproductive response to host plant characteristics, 2013-2014

This data release includes metadata and tabular data documenting the reproductive response of the Samoan swallowtail butterfly (Papilio godeffroyi) to characteristics of its host plant (Micromelum minutum) and habitat. Data was collected at approximately monthly surveys of marked host trees at eight sites, mostly in or adjacent to the National Park of American Samoa (NPSA), Tutuila Island, during

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 property; th

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 projected inc

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 locations in

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

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

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 Hawaii. Ou

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. We used ob

WATRMod, a Water-budget accounting for tropical regions model--source code, executable file, and example files

This data release contains the source code, executable file, and example files for WATRMod, a Water-budget Accounting for Tropical Regions Model code that is documented in U.S. Geological Survey Open-File Report 2022-1013 available at https://doi.org/10.3133/ofr20221013. The source code is written in the Fortran computer language. The model source code was compiled using Intel(R) Visual Fortran In

Seepage-run discharge measurements, November 15, 2021, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i

This data release contains a comma-delimited ascii file of 16 discrete discharge measurements made at sites along selected reaches of He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i, on November 15, 2021. These discrete discharge measurements form what is commonly referred to as a "seepage run." The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach

Hakalau Forest National Wildlife Refuge host plant associations of Lepidoptera, 2016-2017

This data release includes metadata and tabular data that documents species of caterpillars collected from different plant species at Hakalau Forest National Wildlife Refuge during 2017-2018. Data sets document (1) numbers of caterpillars collected on each plant species, (2) caterpillar host plant associations, (3) the fate of caterpillars during rearing, (4) types of mandibles possessed by differ

Keamuku Maneuver Area vegetation, soil, and foliar data 2013-2016

This data release includes data and metadata on “(1) outplant survival, (2) post-disturbance percent cover, (3) post-disturbance shrub counts, (4) point-intercept vegetation data, (5) random plot coordinates, (6) soil chemistry and ratios, and (7) soil moisture. All sites were within Keamuku Maneuver Area on Hawaii Island. This study looked at how microtopography and biotic interactions influence
