This data release contains three 10-meter resolution GeoTIFFs representing 10-meter (35-foot), 30-meter (100-foot) and 90-meter (300-foot) riparian buffer zones along shorelines, rivers, streams, and other lotic (flowing) water features. The layers are binary, where the value of each cell represents the presence or absence of the buffer zone. In addition, the data release contains shapefile layers that document the extent of corrections that were made to the data to address errors in the stream network (see processing steps section for more details). The methodology combines various fine-scale input layers, including a 1:24k stream network and Chesapeake Bay 1-meter resolution Land Use/Land Cover to approximate...

Data consist of presence / absence records of planktic foraminifer species from 5 core samples at 3 localities in southeast Florida. Samples are placed in biostratigraphic zones and ages are estimated from calibrated first and last appearances of select taxa.

Previous research identified species of invasive plants in Hawai'i which are highly flammable and act as fuels in wildfires across Hawai'i. This work aimed to map the distribution of these species (largely grasses) around the islands of Hawai'i with the goal of using the locations for species distribution modeling. All data represents presence data, no absence data were recorded. Data are largely from within the past 20 years, but some georeferenced herbarium specimens go as far back as 1905. Data were obtained from georeferenced herbarium specimens, vegetation plot data, citizen science data (iNaturalist) reviewed by the authors, and data from roadside surveys conducted as part of this research to map these species....

This data release contains the concentration results for basic water-quality constituent class parameters (water temperature, pH, turbidity, and specific conductance), total nitrogen, total phosphorous, chloride, and trace elements in surface-water samples collected from two subsites within two vernal pools near Pleasant Grove, New Jersey in 2022-23. In the winter (December 2022 and February 2023) samples were collected at opposing ends of the ponds, or wherever ponding was sufficient for a sample to be taken. An additional sample was collected in July 2023 during the amphibian breeding season. The number of samples collected during each sampling event varied based on water availability and in July 2023 only one...

These model objects are the outputs of three Boosted Regression Tree models (for three different time periods) to explore the role of climate change and variability in driving ecological change and transformation. Response variables were the proportion of sites in each ecoregion with peak rates of change at 100-year time steps. Predictor variables included temperature anomaly, temperature trend, temperature variability, precipitation anomaly, precipitation trend, precipitation variability and ecoregion, also at 100-yr time steps. Models focused on the most distant time periods (0-21000 BP and 7500 - 21000 BP) show that rapid vegetation change was initiated across these landscapes once a 2 ℃ temperature increase...

These model objects are the outputs of two Bayesian hierarchical models (one for the Middle Rockies and one for the Southern Rockies) to explore the role of landscape characteristics in climate-driven ecological change and transformation. We used the rate of change for each site at 100-yr time steps as the response variable, and included elevation, CHILI, aspect, slope, and TPI as fixed effects in the models, run separately for each ecoregion. We included a random intercept of site to quantify the magnitude of site-level variation in rate-of-change that may be unaccounted for by our covariates.

The East Pisco Basin is one of several forearc basins situated on the coastal plain of Peru between the Andean Cordillera and Peru-Chile Trench. During the Cenozoic, successive marine transgressions across the East Pisco Basin deposited sequences of Paleogene and Neogene age. Biochronologic studies suggest that a hiatus of approximately 12 million years (~32-20 Ma) separates the youngest Paleogene deposits from the oldest Neogene deposits. A newly recognized lower Miocene sequence, provisionally named the Tunga Formation, shortens that hiatus. The following database provides location and description of samples from the East Pisco Basin, checklists of microfossil assemblages, and taxonomic notes for those assemblages.

This database integrates a list of vegetation transformations that occurred across the Southern and Middle Rockies since 21,000 years ago, the age of occurrence, the type of vegetation switch that occurred, whether the rates of vegetation change peaked at that time, and when applicable, the duration of peak rates of vegetation change.
