Hawai‘i Island ʻōpeʻapeʻa (Hawaiian hoary bat; Lasiurus semotus) mist netting effort, capture, and tag retention, 2018–2021 Hawai‘i Island ʻōpeʻapeʻa (Hawaiian hoary bat; Lasiurus semotus) mist netting effort, capture, and tag retention, 2018–2021
‘Ōpe‘ape‘a (Hawaiian hoary bats; Lasiurus semotus) were surveyed at 23 sites on Hawaiʻi Island from 33 to 2,341 m elevation from May 2018 to August 2021. Of the 23 sites, 8 were established as fixed survey sites for sampling at repeated intervals from January 2019 through January 2021. We surveyed each fixed site at least once per four-month period (January–April, May–August, September...
Hawaiʻi Island ʻōpeʻapeʻa (Hawaiian hoary bat) roost data, 2018–2021 Hawaiʻi Island ʻōpeʻapeʻa (Hawaiian hoary bat) roost data, 2018–2021
Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island from 2018-2021. We examined resource selection at multiple spatial scales - perch location within a roost tree, roost tree, and forest stand. We used a discrete choice modeling approach to investigate roost selection and describe attributes of day-roost trees...
Puuhonua o Honaunau and Kaloko-Honokohau National Historical Parks, carbon dioxide treatment and qPCR eDNA assays for eradicating and monitoring invasive fish in anchialine pools, 2019-2022 (ver. 2.0, July 2023) Puuhonua o Honaunau and Kaloko-Honokohau National Historical Parks, carbon dioxide treatment and qPCR eDNA assays for eradicating and monitoring invasive fish in anchialine pools, 2019-2022 (ver. 2.0, July 2023)
This data release includes metadata and tabular data that documents lab and field trials testing the efficacy of carbon dioxide (CO2) gas diffused into water to manage invasive fish in anchialine pools. The data release also includes information documenting sensitivity, specificity, and accuracy of quantitative polymerase chain reaction (qPCR) assays to detect environmental DNA (eDNA)...
Hawaiian forest bird avian malaria prevalence 2018-2021 Hawaiian forest bird avian malaria prevalence 2018-2021
Native and introduced forest birds were captured and then released across the Hawaiian Islands to acquire a blood sample for obtaining DNA and test for exposure to avian malaria (Plasmodium relictum). A total of 2,945 samples were collected and analyzed for avian malaria prevalence from 39 species captured at 66 sites from Kauai, Oahu, Molokai, Maui, and Hawaii islands.
Moloka'i, Hawai'i rapid assessment of hydrology, soils, and vegetation in coastal wetlands 2022 Moloka'i, Hawai'i rapid assessment of hydrology, soils, and vegetation in coastal wetlands 2022
In this project, we assessed the potential for twelve coastal wetland sites on the island of Molokaʻi, Hawaiʻi, to provide socio-cultural resources and habitat for flora and fauna following restoration. In April 2022, a rapid field assessment of hydrology, soils, and vegetation was carried out at each of the wetland sites. The data provided here were collected in order to inform a...
Hawaiian Islands excess rainfall conditions under current (2002-2012) and future (2090-2099) climate scenarios Hawaiian Islands excess rainfall conditions under current (2002-2012) and future (2090-2099) climate scenarios
One of the determinants of runoff is the occurrence of excess rainfall events where rainfall rates exceed the infiltration capacity of soils. To help understand runoff risks, we calculated the probability of excess rainfall events across the Hawaiian landscape by comparing the probability distributions of projected rainfall frequency and land cover-specific infiltration capacity. We...
Hakalau Forest NWR seedling and substrate data, 2015 Hakalau Forest NWR seedling and substrate data, 2015
This data release includes data and metadata on seedling counts and substrate cover in forest plots in Hakalau Forest National Wildlife Refuge on Hawaiʻi Island. Broadly, this study asks how seedlings densities relate to their microsites in terms of grass cover and nurse log and moss presence.
Hawaii Volcanoes National Park plant-soil feedbacks and fire data, 2019 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...

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...
O'ahu waterbird movement from 2016 to 2018 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)...
Hawaiian Islands climate compatibility of Coconut Rhinoceros Beetle (CRB, Oryctes rhinoceros) based on global and local species occurrences 2022 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...
