Data

We integrated recent climate model projections developed for the State of Hawai’i with current climatological datasets to generate updated regionally defined bioclimatic variables. We derived updated bioclimatic variables from new projections of baseline and future monthly minimum, mean, and maximum temperature (Tmin, Tmean, Tmax) and mean precipitation (Pmean) data at 250 m resolution. We used ob

This data release includes metadata and tabular data that documents species of caterpillars collected from different plant species at Hakalau Forest National Wildlife Refuge during 2017-2018. Data sets document (1) numbers of caterpillars collected on each plant species, (2) caterpillar host plant associations, (3) the fate of caterpillars during rearing, (4) types of mandibles possessed by differ

This data release includes data and metadata on “(1) outplant survival, (2) post-disturbance percent cover, (3) post-disturbance shrub counts, (4) point-intercept vegetation data, (5) random plot coordinates, (6) soil chemistry and ratios, and (7) soil moisture. All sites were within Keamuku Maneuver Area on Hawaii Island. This study looked at how microtopography and biotic interactions influence

We examined data from multiple studies (1994-2020) conducted across the avian annual cycle, from multiple locations, to evaluate molt patterns and establish criteria for assignment of age and sex based on the WRP (Wolfe-Ryder-Pyle) method, or molt-cycle age classification system designed specifically for tropical species. In addition, we describe the phenologies of molt and breeding and quantify t

Point count survey data collected from 1998 through 2018 to estimate palila abundance on Mauna Kea. Point counts were conducted on 32 transects surrounding Mauna Kea volcano on Hawaii Island. Transects extended from roughly treeline through the forested area, with survey stations approximately 150 m apart. Counts were conducted for six minutes, during which the species, distance to, and detection

This data release includes metadata and tabular datasets that document (1) Austropuccina, Ceratocystis and Myrtaceae qPCR (quantitative polymerase chain reaction) DNA detections in Passive Environmental Samplers (PES), (2) wind speed, wind gust speed, and wind direction measurements collected at two sites in the Kahuku Unit of Hawai'i Volcanoes National Park (HAVO) where paired PES were located, (

A major advancement in the use of radio telemetry has been the development of automated radio tracking systems (ARTS) which allow animal movements to be tracked continuously. A new ARTS approach is the use of a network of simple radio receivers (nodes) that collect radio signal strength (RSS) values from animal-borne radio transmitters. However, the use of RSS-based localization methods in wildlif

Acoustic sampling for presence of the endangered Hawaiian hoary bat (Lasiurus semotus, also known as Aeorestes semotus) was conducted at 17 stations across four Marine Corps Base Hawaii (MCBH) properties on O‘ahu Island, Hawai‘i. Bats were confirmed as present at all properties; MCBH K?ne?ohe Bay on M?kapu Peninsula, Marine Corps Training Area Bellows (MCTAB) in Waimanalo, Camp H.M. Smith in Halaw

We used an automated radio telemetry network to document the activity of radio telemetered Hawaiian forest birds in two study sites, one a continuous forest and the other a fragmented forest. Four bird species were studied: the nectarivorous 'i'iwi (Drepanis coccinea) and 'apapane (Himatione sanguinea), the frugivorous 'oma'o (Myadestes obscurus), and the generalist Hawai'i 'amakihi (Chlorodrepani

This data release includes metadata and tabular data that document Acacia koa density, basal area, and grass cover before and after the 2018 Keauhou Ranch Fire in Hawaii Volcanoes National Park. Specifically, we asked three questions: 1) At what level of precision can pre-fire grass cover be accurately estimated from oblique aerial photos? 2) How are post-fire Acacia koa regeneration densities aff

Fog has been demonstrated to support plant growth, survival and ecosystem maintenance spanning rainfall and elevation gradients across the world. Persistent fog and strong winds on high mountain slopes in Hawai'i create a unique ecological environment. We collected stem diameter measurements of three native plant species at Nakula Natural Area Reserve, Maui, during 2016-2019 and numerous environme

Eight-minute point-transect distance bird surveys were collected in and around Haleakala National Park from 1993-2008. This dataset contains the location, species, and distance to detected birds, as well as identifying initials to distinguish among observers.
