Vegetation change is an important issue facing managers at Isle Royale National Park (ISRO). These data were created using high-resolution imagery collected in the winter of 2017 which was compared to the vegetation map of the National Park published in 2000 (project imagery collected in 1994 and 1996). These data review where vegetation cover type, density, and pattern have changed since imagery collection for the 2000 publication and provide a proposed reason for the change.

These data represent trapping effort and captures of deer mice at Point Reyes National Seashore, Marin County, California. Deer mice were captured and marked with ear tags to allow identification of individuals. The location of captures can be used in a spatially explicit capture recapture model to estimate density of mice and how mouse density varies by site and habitat type.

The Hawaii Forest Bird Survey (HFBS) systematically characterized plant and bird communities across transects spanning all major Hawaiian Islands except O‘ahu. This extensive dataset has now been organized into a database and associated geographic information system (GIS) layers. This baseline provides an opportunity to assess how forest ecosystems and their constituent bird and plant populations have changed over time. As part of the HaBiTATS (Hawaiian Biodiversity Trends Across Time and Space) project, a select area on Hawai‘i Island was surveyed in 2015 with the objective of demonstrating the potential of using the HFBS methodology to reassess the status of bird and plant communities across multiple geographic...

In Hawai‘i and other oceanic islands with few native land mammals, black rats (Rattus rattus) are among the most damaging invasive vertebrate species to native forest bird populations and habitats, due to their arboreal behavior and generalist foraging habitats and habitat use. This is a selected data set used to assess the impacts of rodenticide treatment on black rat (Rattus rattus) abundance within Hawaii Volcanoes National Park (HAVO). The key objective was to identify rat abundance before and after rodenticide treatment, using paired non-treatment and treatment plots at high elevation (1700-1830m) and low elevation (1220-1340 m). This dataset includes the results of a mark recapture study that took place within...

These data address experimental evaluations of dietary preference by captive brown treesnakes on Guam. Snakes were collected from the wild in areas with birds present and in areas without birds present 2018–2019. Snakes were then run through preference trials during which they were offered first live lures (mouse and finch) in snake traps on opposite sides of the arena. On the second night, snakes were offered dead carrion (baits) of each prey type (mouse, chicken chick) equal to 30% of their mass. Choices were monitored overnight using game cameras and then transcribed the following day. Individuals were classified as BIRD or NOBIRD snakes based on whether they had birds in their gut contents at the time of capture....

This data release includes data and metadata on 1) the coverage and composition of plants 2) species specific plant traits 3) sampling locations and 4) environmental data. All sites were within Hawaii Volcanoes National Park on Hawaii Island. Plant cover data were obtained from National Park Service Inventory and Monitoring Program. Plant trait data was collected for these plots in 2014. This study aims to evaluate how traits of native and exotic plant species change along environmental gradients and what this suggests for plant competition and invasion.

These data include Ceratocystis culture viability results from ambrosia beetle (Coleopetera: Scolytinae) frass. Frass is defined as fine particles of macerated wood or boring dust, beetle parts, and feces. Frass was collected from individual ambrosia beetle galleries in Ceratocystis-infected ʻōhiʻa (Metrosideros polymorpha) trees on Hawaiʻi Island, a phenomenon referred to as Rapid ʻŌhiʻa Death (ROD). We recorded the height at which these beetles produced frass, how long we collected frass from galleries, and the total number of culturing tests from individual galleries.

We examined Hawaiian hoary bat (Lasiurus semotus) presence and foraging activity at Hakalau Forest National Wildlife Refuge and Lāupahoehoe 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 nightly from May 2013 through September 2013. We compared these data to data collected at similar locations during 2007-2011 to determine the response of bats to increased moth abundance during 2013. In this abstract we refer to the Hawaiian hoary bat as a full species, Lasiurus semotus, following updated taxonomy for Hawaiian hoary...

This data release documents specificity of quantitative polymerase chain reaction (qPCR) assays to detect environmental DNA (eDNA) from tilapia, western mosquito fish and guppies. These assays provide new tools for resource managers to monitor effectiveness of management efforts to remove invasive fish from anchialine pools in Hawaii and to also survey pools for presence and absence of invasive fish. The lab work was conducted during 2019-2022.

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. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. Broadly, this study asks what thresholds of seed rain and native and exotic plant cover are needed for passive forest regeneration.

This data set consists of digital data describing wetlands and uplands habitats for the Mississippi Coastal Improvements Program (MsCIP) area, consisting of Cat, Ship, Horn and Petit Bois Islands for the year 2020. Wetlands were classified using the Cowardin, et al., wetlands classification scheme to the level of freshwater and tidal, salinity modifiers. Uplands were classified using a customized classification scheme which can be cross-referenced to Anderson, et. al. For this dataset, upland dunes were delineated as areas at or above 1.524 meters (5 feet) as determined in the Lidar data that was referenced without modification for this classification. With this elevation criteria some delineated upland dune features...
