In this experiment at Waiākea Forest Reserve, we tested the efficacy of the semiochemical repellent, verbenone, in commercial SPLAT® Verb formulation, at protecting healthy and rapid ʻōhiʻa death-Ceratocystis infested ʻōhiʻa from ambrosia beetle colonization in the 2022 and 2023 field seasons. Data files include 1) raw beetle counts, 2) individual tree information, and 3) verbenone mean...

This data publication contains information collected as part of a field and laboratory effort to determine prevalence of avian malaria (Plasmodium relictum) and pox-like lesions (Avipoxvirus spp.) in native and non-native forest birds on the northern, high elevation (>1500 m) slopes of Haleakala volcano on Maui during the last decade of the 20th century. Forest bird banding data and...

This data publication contains information collected as part of a field, laboratory, and modeling effort aimed at uncovering ecological drivers of avian malaria transmission and impacts on Hawaiian honeycreepers across an altitudinal gradient on the eastern flank of Mauna Loa and Kilauea volcanoes. Forest bird banding data and blood samples for diagnosis of Plasmodium relictum, the agent...

This USGS data release consists of five data sets and accompanying metadata for an experimental mark-release-recapture (MMR) study of adult Culex quinquefasciatus conducted in a montane rainforest in Upper Waiākea Forest Reserve on the Island of Hawai'i from October-December 2020 and laboratory survivorship studies and analysis from 2021- 2024. Culex quinquefasciatus is the vector of the...

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).

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. .

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...

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...

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...

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...

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...
