Island of Hawai‘i, ‘Io (Hawaiian hawk) GPS tracking locations, 2019-2020 Island of Hawai‘i, ‘Io (Hawaiian hawk) GPS tracking locations, 2019-2020

We tracked the movement of 15 ‘Io, or Hawaiian Hawks (Buteo solitarius) from 2019-2021. Individuals were tracked for up to 18 months across a diverse landscape on the eastern side of the Island of Hawai'i. GPS-GSM (global positioning system location with global system of mobile communications) tracking tags were placed on each bird, with locations obtained every 1 hour during diurnal...

This data release includes data and metadata documenting Ceratocystis viability, moisture content, and beetle activity in felled and tarped ʻōhiʻa lehua (Metrosideros polymorpha) trees previously having been determined to be infected with either Ceratocystis lukuohia or Ceratocystis huliohia, the fungi that cause rapid ʻōhiʻa death (ROD).

Wake Atoll yellow crazy ant survey, 2023 (ver. 2.0, October 2024) Wake Atoll yellow crazy ant survey, 2023 (ver. 2.0, October 2024)

This data release includes metadata and tabular data that documents the distribution of yellow crazy ants (Anoplolepis gracilipes) across Wake Atoll. The three islands that comprise the atoll were systematically searched by hand. The dataset describes the outcome of searching 3,675 cells, each 50 x 50 m in size, during 6-21 October 2023. .

South Kona, Island of Hawai'i Epizootiology and control of avian malaria (Plasmodium relictum) across an altitudinal gradient 1993-2000 South Kona, Island of Hawai'i Epizootiology and control of avian malaria (Plasmodium relictum) across an altitudinal gradient 1993-2000

This data release includes metadata and tabular data from a field study of avian diseases (malaria and pox virus) that threatened recovery of the last extant population of ‘Alalā (Corvus hawaiiensis) before it went extinct in the wild in the early part of the 21st century. The study focused on habitat occupied by the last remaining wild ‘Alalā and determined prevalence of avian malaria...

Conterminous U.S. data used for modeling non-native vascular plant first records 1780-2022 Conterminous U.S. data used for modeling non-native vascular plant first records 1780-2022

This dataset was used for modeling the spatial distribution of first records of non-native plants in the conterminous U.S. The input dataset (alldata_input_frdm.csv) contains 4,763 rows of data, representing 1,538 counties in the contiguous U.S., 25 decades, and 3,389 first records of invasive terrestrial plant species (Williams et al., 2024) found in the US-RIIS list (Simpson et al...

Midway Atoll survey of avian malaria prevalence in passerines 2023 Midway Atoll survey of avian malaria prevalence in passerines 2023

Non-native passerines, common canary (Serinus canaria; n=24) and the common myna (Acridotheres tristis; n=19), were captured by US Fish and Wildlife Service Biologists on Sand Island, Midway Atoll, and had a blood sample taken to test for avian malaria (Plasmodium relictum) infection. Blood samples were analyzed for the presence of avian malaria DNA using a Realtime PCR (qPCR) assay. No...

Kīpahulu Valley, Haleakalā National Park, Maui Seasonal Distribution and Relative Abundance of the Mosquito Culex quinquefasciatus, 2022-2023 Kīpahulu Valley, Haleakalā National Park, Maui Seasonal Distribution and Relative Abundance of the Mosquito Culex quinquefasciatus, 2022-2023

This USGS data release consists of six data sets and accompanying metadata for a year-long study on the seasonal distribution and relative abundance of the southern house mosquito Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, critical habitat for two endangered Maui endemic forest birds. Culex quinquefasciatus is the vector of the avian malaria Plasmodium relictum...

Guam, Andersen Air Force Base housing area visual surveys for brown treesnakes (Boiga irregularis) and associated tree data, December 2019–November 2022. Guam, Andersen Air Force Base housing area visual surveys for brown treesnakes (Boiga irregularis) and associated tree data, December 2019–November 2022.

This data was collected as part of a larger project to examine predator-prey interactions between invasive Brown Treesnakes (Boiga irregularis, predator) and native prey species at a study site located in a peri-urban area of Andersen Air Force base in Guam, USA. This dataset includes two datasets. One dataset contains 22 columns and includes data collected on Brown Treesnakes captured...

Hawaiian Islands habitat suitability models for highly invasive plants based on global and regional data for baseline climate scenario (1990-2009) Hawaiian Islands habitat suitability models for highly invasive plants based on global and regional data for baseline climate scenario (1990-2009)

We created a comprehensive estimate of potential distribution for a subset of 17 ecosystem modifying invasive plants (EMIPs) in Hawaiʻi. This work uses methods that integrate a wide set of data sources including agency and citizen science data, but perhaps more importantly, the integration of regional and global distribution information for these species. We built three sets of ensemble...

Kaloko-Honokōhau National Historical Park shrimp density and anchialine pool characteristics, 2017 Kaloko-Honokōhau National Historical Park shrimp density and anchialine pool characteristics, 2017

This data release includes metadata and tabular data that documents counts of shrimp and measurements of field variables aimed to identify factors that affect the distribution and abundance of the uncommon anchialine pool shrimp Metabetaeus lohena at Kaloko-Honokōhau National Historical Park during 2017. The data set documents biological, chemical and physical attributes within 173...

Guam, Morphometric and height data for brown treesnakes were detected at four sites on Guam, 2006 - 2023 Guam, Morphometric and height data for brown treesnakes were detected at four sites on Guam, 2006 - 2023

These data were collected as part of several studies or efforts to remove brown treesnakes (Boiga irregularis) across three sites located in Guam, USA and one site in Cocos Island (Dano), Guam, USA. The various goals of projects were distinct and these data were applied to a more intensive, cross site comparison on the height snakes were detected during visual surveys as a function of...

Guam, Post-storm Mariana swiftlet colony size and nest counts, 2023 Guam, Post-storm Mariana swiftlet colony size and nest counts, 2023

The Yǻyaguak (Mariana Swiftlet; Aerodramus bartschi) is an endangered cave-roosting species native to Guam and southern Mariana Islands, Micronesia. On May 24-25, 2023, Guam was hit by the category-4 Typhoon Mawar, which brought wide-spread destruction to the island. Approximately 6 weeks prior to the typhoon in April 2023 we conducted surveys of the three known colonies of Yǻyaguak at...
