Hawai'i Island locations of 'Apapane and 'I'iwi from automated radio telemetry tracking system 2014 to 2016

We used an automated radio telemetry network to track the movement of two nectivorous Hawaiian honeycreepers, the 'Apapane (Himatione sanguinea) and 'I'iwi (Drepanis coccinea), collecting high temporal and spatial resolution data across the annual cycle. We identify movement syndromes using a multivariate analysis of multiple movement metrics and assessed seasonal changes in movement behavior. Bi

Hakalau litter, frass, soil, and understory foliar nitrogen during a koa moth outbreak, 2013-2014

This data release includes metadata and tabular data that document estimates of litterfall, koa moth (Scotorythra paludicola) caterpillar frass production, soil nutrients, and foliar nutrients during 2013-2014 at Hakalau Forest National Wildlife Refuge. During this time, there was a massive defoliation event of Acacia koa (koa) trees by the koa moth. We monitored these metrics in 4 sites that vari

Florida invasive Leiocephalus carinatus ecological niche model, thermal environment, and thermal tolerance, 1991-2020

The publication "Invaders from Islands: Thermal Matching, Potential, or Plasticity?" is comprised of data derived from multiple datasets. These datasets include climatic and temperature variables used in ecological niche models for predicting suitable habitat for Leiocephalus carinatus in its invaded and native ranges. Also included are thermal tolerance measurements assessed in March 2020 for Lei

Hawaii Island insect response to koa moth (Scotorythra paludicola) outbreak, 2013-2014

This data release includes metadata and tabular data that document the responses of koa moths and other insects to changes in habitat conditions before and after koa (Acacia koa) defoliation by koa moth caterpillars (Scotorythra paludicola) at Hakalau Forest National Wildlife Refuge during 2013-2014. Data sets document changes in (1) koa moth abundance, (2) koa moth caterpillar abundance, (3) koa

Hawaii Island tree response to koa moth outbreak, 2013-2014

This data release includes metadata and tabular data that document the response of koa (Acacia koa) trees to defoliation by the koa moth (Scotorythra paludicola) during 2013-2014 at Hakalau Forest National Wildlife Refuge. Data were collected on 55 plots at 4 sites representing 2 habitat types with either high or low koa densities. Ohia (Metrosideros polymorpha) trees dominated habitats with low k

Hawaii Island bird response to koa moth outbreak, 2013-2014

This data release includes metadata and tabular data that document the responses of birds to changes in habitat conditions before and after koa (Acacia koa) defoliation by koa moths (Scotorythra paludicola). Data sets document changes in the (1) use of tree species, (2) arthropod composition of diets, and (3) body mass.

Hakalau Forest NWR seed rain, seedling, and plant data for 2017-2019

This data release includes data and metadata on tree and shrub basal area as well as bird-mediated and passive seed rain for sites selected to have a range of understory cover under canopy trees (Metrosideros polymorpha and Acacia koa). It also includes seedling germination and survival data for a large-scale seed addition and grass removal experiment that varied both seed rain and grass cover. Al

Hawaii Island locations of reintroduced Alala from automated radio telemetry tracking system, 2017 cohort

Alala, or Hawaiian Crow (Corvus hawaiiensis), were extinct in the wild since the early 2000s. The first effort to reintroduce captive bred Alala back into the wild was conducted at Puu Makaala Natural Area Reserve on Hawaii Island. The 2017 release cohort were released in two stages and were the only Alala in the wild. Using automated radio telemetry tracking towers (n=4) that were distributed aro

Kaua'i Avian Botulism Surveillance Using Detector Canines 2017-2018

Hawai'i's endangered waterbirds have experienced epizootics caused by ingestion of prey that accumulated a botulinum neurotoxin produced by the anaerobic bacterium Clostridium botulinum (avian botulism; Type C). Waterbird carcasses, necrophagous flies, and their larvae initiate and spread avian botulism, a food-borne paralytic disease lethal to waterbirds. Each new carcass has potential to develop

Hawaiian Islands Hawaiian Hoary Bat Genetic Sexing 2009-2020 (ver. 6.0, January 2021)

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 American hoary b

Alakai Plateau, Kauai, and Volcano Village,Hawaii biopesticides and traps for the control of Culex quinquefasciatus, 2017-2018

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 malaria P

Hakalau Forest National Wildlife Refuge Vegetation Map 2016

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.
