We tested the utility of a protocol using genetic markers that previously proved successful to identify the sex of Vespertilionid bats on tissues collected from live bats and carcasses of varying age from the Hawaiian hoary bat (Lasiurus cinereus semotus). This molecular method is based on genes unique to X and Y chromosomes in mammals and previously was used successfully on North...

This USGS data release consists of seven data sets and accompanying metadata for studies on the efficacy of adult mosquito traps and lures for monitoring populations of the invasive mosquito Culex quinquefasciatus and the efficacy of the biopesticide VectoMax FG for control of larval Culex quinquefasciatus in Hawaiian forest bird habitat. Culex quinquefasciatus is the vector of the avian...

This data layer identifies the boundaries of the mapped plant communities for the vegetation map of the Hakalau Forest National Wildlife Refuge Hakalau Forest Unit and adjacent lands, island of Hawaii.

Monitoring demographic response over time is valuable for understanding population dynamics of endangered species. We quantified the variation in survival patterns for three small isolated island populations of endangered Laysan ducks (Anas laysanensis; also called Laysan teal) in the Hawaiian Archipelago using data from individually marked birds. Using the median or maximum resight...

This data release includes metadata and tabular datasets that document (1) Ceratocystis qPCR DNA detections in Passive Environmental Samplers (PES), (2) Ceratocystis qPCR DNA detections after pre-amplification, (3) wood and frass particle counts detected in PES (4) location of individual PES within the study area (5) ambrosia beetle gallery counts on felled 'ohi'a (6) ambrosia beetle...

This data release includes data and metadata on litterfall rates, foliar nitrogen and carbon, grass biomass, soil nitrogen and carbon, and native outplant survival rates for an experiment that added large quantities of woody litter to a restoration forest in an attempt to lower soil nitrogen and exotic grass biomass. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii...

This data release includes data and metadata on 1) avian diet 2) seed rain 3) understory plant composition 4) seedling abundance and 5) sampling locations for these sites. In addition it includes data on seedling abundance, grass cover and light levels for a grass removal/seed addition experiment . All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. This study...

We examined Hawaiian hoary bat (Lasiurus semotus) presence and foraging activity at Hakalau Forest National Wildlife Refuge and Lupahoehoe Forest Reserve on Hawai'i Island during the 2013 koa moth (Geometridea: Scotorythra paludicola) outbreak. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1069 and 1200 m above sea level that operated...

This dataset features tissue collection information, reference genome assembly, and single nucleotide polymorphisim (SNP) genotypes of 23 Hawaiian hoary bats collected across four Hawaiian Islands, Hawaii, Maui, Oahu, and Kauai. These data were collected in order to examine the phylogenetic history and patterns of genetic variation in the Hawaiian hoary bat. The raw sequencing data are...

This data release includes data and metadata containing (1) study site locations and elevation where bolts (tree stem sections) infected with Ceratocystis lukuohia and/or C. huliohia were collected on Hawai'i Island, (2) the ambrosia beetle (Coleoptera: Scolytinae) species that were reared from bolts, (3) Ceratocystis spp. viability results from culturing tests of the beetles' frass, (4)...

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...

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...
