Data

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...

This data release contains a comma-delimited file of 71 well measuring-point altitudes for monitored wells in the Hālawa area, O‘ahu, Hawai‘i. The measuring-point altitude of a monitoring well is needed to determine the groundwater level in the well relative to a datum such as local mean sea level. A well measuring point is typically located at the top of the well casing. By surveying...

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...

The shapefiles in this dataset represent the spatial distribution of mean annual water-budget components, in inches, for Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Maui, and the Island of Hawaiʻi, for a set of recent and future climate conditions, and 2020 land cover. The four main climate scenarios used in the water-budget analyses include a reference climate scenario representative of recent...

This dataset contains pesticide-concentration values and other information for water samples and quality-control samples collected at surface-water sites on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi between November 2016 and June 2019. The water water samples and quality-control samples were collected for a study that assessed pesticides in surface water in Hawaiʻi, as...

The U.S. Geological Survey (USGS) deployed passive samplers at surface-water and groundwater sites on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi for several weeks each during 2015–19. The passive samplers were deployed to assess the occurrence of pesticides and pesticide degradates, herein referred to as pesticides, in water at the sites. Some of the passive samplers were...

This dataset includes information for the sample sites in Hawaiʻi where pesticides in surface water were assessed during 2015–19. The sample sites were distributed on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi. The site information is provided in two formats: a comma-separated-value (CSV) file and a shapefile formatted for use in a geospatial information system. A summary...
