Data

Dataset includes publicly available geologic and rainfall data, and environmental and ecological data derived or collected for this project. Specifically, water infiltration measurements, interpreted field-saturated hydraulic conductivity values, ungulate activity, vegetation cover, general soil and weather conditions data are included. Soil samples were collected, lab analyzed, and are included i

Acoustic sampling for occurrence of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) was conducted at 18 "long-term" acoustic monitoring stations on 12 Hawaii Army National Guard (HIARNG) installations across the islands of Hawaii, Maui, Molokai, Oahu, and Kauai between 2012 and 2018. Hawaiian hoary bat insect prey sampling with paired acoustic monitoring was conducted at Keaukaha Mil

This data set provides the simulated results of releasing malaria-resistant Iiwi into existing populations of wild birds on the Island of Hawaii. Resistant birds are released into mid- and high-elevation forests at different densities at 10-year intervals from 2030 to 2070. Populations of both malaria-resistant and susceptible Iiwi are then predicted at 10-year intervals from release until 2100. P

This data release includes data and metadata on 1) the coverage and composition of bryophytes and other ground cover, 2) seedling abundance, composition, and rooting substrate and 3) sampling locations. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. This study aims to evaluate the role of bryophytes in seedling recruitment and thus forest regeneration in different

Habitat use, diet, prey availability and foraging ecology of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus, Vespertilionidae) were examined in the east Maui region inclusive of the Waihou Mitigation Area, Pu'u Makua Restoration Area and the wind power facility operated by Auwahi Wind Energy, LLC. The study was conducted to inform the mitigation and management requirements of Auwahi

We examined habitat use and foraging activity of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus), as well as nocturnal aerial insect abundance at Kaloko-Hon kohau National Historical Park located in the coastal region of Kailua-Kona, Hawai'i Island. The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Hawaiian hoary bat echolocation vocalization

Hawaiian hoary bats (Lasiurus cinereus semotus) on Hawaii island were surveyed intermittently from 2004-2010. This data release is a single table of resulting bat location estimates, including date, time, coordinates for each location, and presumed bat activity at the time of collection. Nightly movements were documented for 30 Hawaiian hoary bats along the windward (eastern) side of the island of

We analyzed very-high-resolution imagery to assess status of Metrosideros polymorpha forests across an 83,603-hectare study area that experienced extensive canopy dieback in the 1970s on the eastern side of the island of Hawaii. Using GIS we generated 1,170 virtual vegetation plots with a 100-m radius; 541 plots in areas mapped in 1977 with trees dead or mostly defoliated (dieback), and 629 plots

These data include metadata and associated data files associated with the manuscript, "Economical Environmental Sampler Designs for Detecting Airborne Spread of Fungi Responsible for Rapid Ohi'a Death." These data include a total of 8 datasets used for both controlled and field studies evaluating the use of Active (with battery operated fan) and Passive (dependent on wind) USGS Environmental Samp

The newly identified rapid ohii death (ROD; Metrosideros polymorpha) originated in the lower Puna district and its distribution has spread across Hawaii Island. As ROD expands it is expected that the loss of the dominant tree species will adversely affect bird populations. This project is a first attempt to describe the relationship between the impacts of ROD on the Hawaiian avifauna, especially t

In Hawaii and other oceanic islands with few native land mammals, black rats (Rattus rattus) are among the most damaging invasive vertebrate species to native forest bird populations and habitats, due to their arboreal behavior and generalist foraging habitats and habitat use. We evaluated the nesting response of Hawaii Elepaio (Chasiempis sandwichensis; Monarchidae), a generalist insectivore, to

These are the datasets for the Hawaii Forest Bird Survey (HFBS) and the Hawaiian Biodiversity Trends Across Time and Space project that systematically characterized plant and bird communities. The HFBS sampled from transects spanning all major Hawaiian Islands except O'ahu. This extensive dataset has now been organized into a database and associated geographic information system (GIS) layers. This
