Hawai'i Rapid 'Ohi'a Death Decontamination 2019-2020

Rapid 'Ohi'a Death is a fatal disease caused by Ceratocystis lukuohia and C. huliohia that are decimating Hawai'i's keystone trees species, 'ohi'a (Metrosideros polymorpha). We developed practical and effective decontamination practices for both cultured C. lukuohia and C. huliohia as well as Ceratocystis spores embedded in ambrosia beetle frass (fine particles of macerated wood or boring dust, be

Hawaii Volcanoes National Park stable isotope values from Hawaii forest birds 2012

Blood and feathers were collected from Hawaii forest birds (Apapane and Hawaii Amakihi) in high elevation forest to assess evidence for altitudinal movement. Feathers, red blood cells and plasma were analyzed for hydrogen, carbon, and nitrogen stable isotope ratios, and these were used to infer changes in elevation and diet over time. For each species, at one of 3 sites, isotope values from one or

Hawaii Island, Hawaiian hoary bat roosting ecology and detection 2018-2019

The Hawaiian hoary bat (Lasiurus cinereus semotus), a federally and state listed endangered subspecies, is the only extant native terrestrial mammal in the Hawaiian archipelago. It is an insectivorous, solitary and foliage-roosting species that generally roosts alone or in mother-pup family groups. A total of 58 bats (17 female; 41 male; 56 adult; 2 juvenile) were captured at multiple locations on

Lanai habitat and ecological associations of two non-native ungulate species 2011

This series of five raster datasets includes three input rasters developed to model habitat suitability for two ungulate species on the island of Lanai; the two habitat suitability model raster datasets are also part of this data release. Input datasets were derived from WorldView-2 data to create vegetation (hereafter, NDVI) and bare ground indices, and from a Digital Elevation Model (DEM) to cre

Keaukaha Military Reservation Ohia Restoration under ROD-infected Trees 2019-2020

This data release includes data and metadata containing (1) Ohia (Metrosideros polymorpha) tree locations tested for Rapid Ohia Death (ROD) at Keaukaha Military Reserve, Hilo, HI (2) out-planted Ohia seedling information and survival status and (3) raw quantitative polymerase chain reaction (qPCR) results for all Ceratocystis lukuohia and huliohia testing. Data were used in the analysis for the ma

Maui Island, Hawaiian hoary bat behavior at wind turbines, 2018

The Hawaiian hoary bat (Lasiurus cinereus semotus), a federally and state listed endangered subspecies, is the only extant native terrestrial mammal in the Hawaiian archipelago. It is an insectivorous, solitary and foliage-roosting species that generally roosts alone or in mother-pup family groups. This data release consists of three tabular datasets comprising acoustic and thermal video data of H

Hawaii Volcanoes National Park Plant Trait, Percent Cover, and Environmental Data 2014

This data release includes data and metadata on 1) the coverage and composition of plants 2) species specific plant traits 3) sampling locations and 4) environmental data. All sites were within Hawaii Volcanoes National Park on Hawaii Island. Plant cover data were obtained from National Park Service Inventory and Monitoring Program. Plant trait data was collected for these plots in 2014. This stud

Oahu U.S. Army Facilities Hawaiian Hoary Bat Acoustic Data 2015-2016

Acoustic sampling for occurrence of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) was conducted at 12 locations on U. S. Army facilities on O'ahu Island, Hawai'i. Bats were confirmed as present at 10 of these locations: Dillingham Military Reservation, Helemano Military Reservation, Kahuku Training Area, Kawailoa Training Area, M'kua Military Reservation, Schofield Barracks East Ra

Hakalau Forest National Wildlife Refuge, Hawaii Akepa point-transect survey, 2002

This dataset contains the point-transect distance sampling records of Hawaii Akepa collected at Hakalau Forest National Wildlife Refuge in 2002, including survey point locations, distance to detected birds, number of detected birds, elevation, and alliance-level habitat classification. This data release consists of two tabular datasets, one that contains distances and the other that contains locat

Hawaii Island forest bird avian malaria detection using whole blood preserved in lysis buffer, 2005-2006

It is unclear whether DNA (Deoxyribonucleic Acid) lysis buffers used for preservation of whole blood samples from Hawaiian forest birds cause denaturation and loss of antigen binding capability of antibody molecules. If their antigen binding capability is not affected, then the samples can be used in serological assays to provide an independent assessment of the accuracy of PCR (polymerase chain r

Hawaii Island forest bird response to simulated nest predator 2015-2016

Hawaii forest birds nesting in Hakalau Forest National Wildlife Refuge were exposed to models of predators near their nests to measure behavioral responses. Responses to potential nest predators included vocalization rate, movement behavior, and nestling feeding. Predators were inert stick, introduced but abundant predator, a rat, and a novel predator, a snake, that does not occur on Hawaii.

Alamagan, Commonwealth of the Northern Mariana Islands, Nightingale Reed-warbler point transect survey data, 2010

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
