Hawaii Island airborne detection of fungal pathogens of Ohia, 2016-2017

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, (

Guam automated radio telemetry network test data 2021

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

Marine Corps Base Hawaii Oahu Hawaiian Hoary Bat Acoustic Data 2019-2021

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. Sm

Hawaii Island bird activity from 2014 through 2019

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

Hawaii Volcanoes National Park plant community and fire severity data, 2018-2020

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

Nakula, Maui environmental controls on plant growth and seedling recruitment in a cloud-affected restoration site, 2016-2019

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

Haleakala National Park bird survey data 1993-2008

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.

Hawaii Island Kohala Mountain complex forest bird survey, 2017

This data release contains the point-transect distance sampling records of forest bird survey collected in the Kohala Mountain complex in 2017, including survey point IDs, distance to detected birds, sampling conditions, ohia phenology, habitat classifications and background noise levels. This data release consists of one tabular dataset.

Florida physiological and morphological data from wild and recently captive Python bivittatus 2018-2019

This dataset provides morphological and blood-derived physiological data from invasive Burmese pythons (Python bivittatus) captured in Florida. Data were collected on pythons at capture in the field and in varying lengths of time in captivity. Samples were collected immediately at handling (baseline) and 1 hour post-restraint. Physiological data include circulating corticosterone hormone levels, f

Maui Island Modeling Scenarios for the Management of Axis Deer 1959-2014

Our objectives were to examine the population history of axis deer on Maui, estimate observed population growth, and then use species-specific demographic parameters in a VORTEX population viability analysis to examine removal scenarios that would most effectively reduce the population. Only nine deer were introduced in 1959, but recent estimates of less than 10,000 deer suggest population growth

Lanai Island Spatial Prioritization of Native Plant Habitat and Hunting Areas, 2021

This data release includes data and metadata on all native plant species, native habitat, and hunting areas included in the spatial prioritization analyses. Broadly, recovery of threatened and endangered species requires specific management actions by natural resource managers at a fine scale. We used a systematic conservation planning framework to outline conservation goals across multiple land-u

Hawaii Volcanoes National Park Forest Composition and Hawaii Elepaio Breeding Behavior 1992-1994 and 2015-2019

This data release contains the tabular data and metadata to record changes in forest composition (tree species relative abundance, tree density, tree height, and tree diameter) over a span from 1993-1994 and 2015-2019. The data also includes Hawaii elepaio breeding territory sizes, and nest site selection (nest tree species, nest tree height, nest tree diameter).
