Data

Point transect distance sampling data were collected during the 2010 surveys of Alamagan, Commonwealth of the Northern Mariana Islands (CNMI). Data were collected at points along transects where trained observers recorded the detection type (heard, seen, or heard then seen) and horizontal distance (exact distance in m) from the station center point to individual birds detected during an 8-min coun

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

A three-dimensional, variable-density solute-transport model (SUTRA) was developed to evaluate the effects of nine selected withdrawal/recharge scenarios on salinity of groundwater and discharge of freshwater to the nearshore environment of central Molokai, Hawaii. The model was constructed using water-level and salinity data available for the period from 1940 to 2012. Groundwater recharge for the

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 contains the shapefiles of mean annual water-budget components for Guam for historic (1990 - 2009) and future (2080 - 2099) climate conditions. Components estimated for the 1990 - 2009 scenario represent an update to the historic (1961 - 2005) components estimated by Johnson (2012), and serve as a historic baseline for the components estimated for the future (2080 - 2099) climate

This data release contains the input files for the watershed and water-balance models that simulate historic (1990-2009) and future (2080-2099) climate conditions on Guam. These simulations are described in the associated Scientific Investigations Report, "Water Resources on Guam-Potential Impacts of and Adaptive Response to Climate Change" by Stephen B. Gingerich, Adam G. Johnson, Sarah N. Rosa,

A previously published three-dimensional, groundwater model (SUTRA) (http://doi.org/10.3133/sir20135216) was used to evaluate the effects of future climate and withdrawal on the freshwater lens of Guam. The model was run using 2080 to 2099 estimated recharge and sea-level rise. This USGS data release contains all of the input and output files for the simulations described in the associat

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

Data were collected in association with locations of standard brown treesnake traps on Guam at location prior to suppression or control efforts and after control had occurred. In all cases study sites were closed or semi-closed populations of brown treesnakes. Habitat data focused on type and structure of the habitat within 10-m of the trap.

This dataset describes land cover and vegetation for the island of Maui, Hawaii, circa 2017, hereinafter the 2017 land-cover map. The 2017 land-cover map is a modified version of the dataset titled "Mean annual water-budget components for the Island of Maui, Hawaii, for recent conditions, 1978-2007 rainfall and 2010 land-cover map" by Johnson (2015), hereinafter the 2010 land-cover map.
