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 including those us

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) from tilapia

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

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 prioritization p

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 characterized

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

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

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 (ver. 2.0, April 2023)

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
