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).

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
