This dataset includes the location and associated summarized temperature and soil moisture values associated with each seedling outplanted in this experiment. Temperature range (Temp.diff) is the average monthly temperature range for the life of the plant and/or experiment. Soil water content (Avg.wc) is the average soil water content for the life of the plant and/or experiment. Each plot and the associated elevation (Elev) are recorded. Each seedling has a unique identifier and all information associated used for data analysis. Survival of each seedling is noted with a 1 (survived) or 0 (died). An index of growth per day, 'slope' is provided for each seedling. Seedlings were planted across eight plots (Plot: A-H)...

This dataset was developed to model habitat suitability for two ungulate species on the island of Lanai. This includes raster data derived from WorldView-2 data to create a normalized difference vegetation index (NDVI). This index, in addition to other datasets, was used to develop habitat suitability models for Axis deer and mouflon sheep. Datasets and indices derived for use in modeling efforts, as well as suitability models, are included within this data release.
Montane plant communities throughout the world have responded to changes in precipitation and temperature regimes by shifting ranges upward in elevation. Continued warmer, drier climate conditions have been documented and are projected to increase in high-elevation areas in Hawai‘i, consistent with climate change effects reported in other environments throughout the world. Organisms that cannot disperse or adapt biologically to projected climate scenarios in situ may decrease in distributional range and abundance over time. Restoration efforts will need to accommodate future climate change and account for the interactive effects of existing invasive species to ensure long-term persistence. As part of a larger, ongoing...

This dataset was developed to model habitat suitability for two ungulate species on the island of Lanai. This includes raster data derived from WorldView-2 data to create a bare ground index. This index, in addition to other datasets, was used to create the habitat suitability models. Datasets and indices derived for use in modeling efforts, as well as suitability models, are included within this data release.
Dataset includes publicly available geologic and rainfall data, and environmental and ecological data derived or collected for this project. Specifically, water infiltration measurements, interepreted field-saturated hydraulic conductivity values, ungulate activity, vegetation cover, general soil and weather conditions data are included. Soil samples were collected, lab analyzed, and are included in the dataset. Field-collected data are associated with plots that encompassed approximately a 3 x 3 m area; site data represent approximately 20 x 20 m. First posted: 4 March 2020 (available from author) Revised: April 13, 2020 (version 2.0) The revision is provided due to minor refinement of the dataset and updated...

Precipitation in HawaiĘ»i’s higher elevation upland areas provides needed water to both people and ecosystems. Once it reaches the ground, rain can either run off and contribute to water flow in streams, or it can infiltrate into the ground and provide water for plants and recharge aquifers and groundwater. The exact route that water takes is controlled by many factors, including the duration and intensity of rainfall, the topography of the land, soil properties, and vegetation. The introduction and spread of invasive plants and animals in Hawaiian forests, which alters the water-use and soil characteristics of ecosystems, can have large impacts on downstream water users. Increased demand and competition for limited...

Watershed degradation due to invasion threatens downstream water flows and associated ecosystem services. While this topic has been studied across landscapes that have undergone invasive-driven state changes (e.g., native forest to invaded grassland), it is less well understood in ecosystems experiencing within-system invasion (e.g. native forest to invaded forest). To address this subject, we conducted an integrated ecological and ecohydrological study in tropical forests impacted by invasive plants and animals. We measured soil infiltration capacity in multiple fenced (i.e., ungulate-free)/unfenced and native/invaded forest site pairs along moisture and substrate age gradients across Hawaii to explore the effects...

This series of five raster datasets includes three input rasters developed to model habitat suitability for two ungulate species on the island of Lanai; the two habitat suitability model raster datasets are also part of this data release. Input datasets were derived from WorldView-2 data to create vegetation (hereafter, NDVI) and bare ground indices, and from a Digital Elevation Model (DEM) to create a ground surface slope dataset. These indices and data, in addition to other datasets, were used to create habitat suitability models for Axis deer and mouflon sheep.
This dataset was developed to model habitat suitability for two ungulate species on the island of Lanai. Slope was derived from a 10-m resolution DEM raster dataset created by NOAA. This dataset, in addition to other datasets, was used to create the habitat suitability models. Datasets and indices derived for use in modeling efforts, as well as suitability models, are included within this data release.

This dataset was developed to model habitat suitability for mouflon sheep on the island of Lanai. Model parameters include: cloud cover at 1400 HST, ground surface slope, mean annual precipitation, NDVI, elevation, bare soil, and deer habitat suitability. Datasets and indices derived for use in modeling efforts, as well as the suitability model developed for axis deer, are included within this data release.

The datasets used in the the research project entitled, "Facilitating Adaptation in Montane Plants to Changing Precipitation along an Elevation Gradient," are presented. One dataset includes survival of individual seedlings after 20 weeks, along with the seedling location and associated summarized temperature and soil moisture values. Another dataset includes growth over time of individual seedlings, along with the seedling location and associated summarized temperature and soil moisture values. All weather data (temperature, soil moisture, and relative humidity summary statistics) considered for the analyses are provided in another file.
