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

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 DNA for po

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 (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 sampled near the

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.
