Hawaii Volcanoes National Park plant-soil feedbacks and fire data, 2019

This data release includes metadata and tabular data that documents growth and root nodulation of Acacia koa and Sophora chrysophylla in different soil types. Soils contained innoculum from conspecific versus heterospecific plants and were taken from areas that had burned in the 2018 Keauhou fire versus areas that had not burned . All plants were grown and data were taken in 2019 in a shadehouse s

Hawaiʻi Ambrosia Beetle Trap Lures and Repellents 2020-2021

This data release includes data and metadata containing (1) ambrosia beetle (Coleoptera: Curculionidae) trapping data using two different lures at Waiākea Forest Reserve and ʻŌlaʻa Forest of Hawai'i Volcanoes National Park, (2) ambrosia beetle trapping data using paired lures and repellents from two trials conducted at Waiākea Forest Reserve, and (3) the localities of all traps used in both trappi

Seepage-run discharge measurements on Hawai'i Island and west Maui, 2021 to 2022

This data release is part of a cooperative study to assess streamflow availability under low-flow conditions for streams on the island of Hawai'i and West Maui from 2021 to 2022. This data release contains seven child items that consist of the following files: (1) a metadata xml file describing the data release files and data attributes, (2) an annotated NWIS-Mapper screen-captured image showing t

Seepage-run discharge measurements, August 9, 2022, 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 August 9, 2022. 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 dur

O'ahu waterbird movement from 2016 to 2018

This data release includes data and metadata containing estimated and predicted locations of radio telemetered Hawaiian waterbirds. Radio telemetry data was collected using an automated radio telemetry network from March 2016 to August 2018 on O'ahu, Hawaii, for three species: ʻAlae ʻula (Hawaiian Gallinule; Gallinula galeata sandvicensis), ʻAlae keʻokeʻo (Hawaiian Coot; Fulica alai), and Aeʻo (Ha

Hawaiian Islands climate compatibility of Coconut Rhinoceros Beetle (CRB, Oryctes rhinoceros) based on global and local species occurrences 2022

The arrival of the coconut rhinoceros beetle (CRB, Oryctes rhinoceros) in Hawaii poses serious threats to endemic palm species, crop species and iconic palm trees across the archipelago. As this invasive is found on the island of Oahu primarily at lower elevations, there are concerns about the species spreading towards high value native habitats at higher elevations and/or to other islands across

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 nectarivorous ʻiʻ

Hawaiʻi Ambrosia Beetle Direct ROD Transmission 2018-2022

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 infected a

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 ex

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 damselflies

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
