Whitebark Pine- Wildfire Severity As a result of climate change, a warmer and drier climate has led to an increase in wildfire severity. Severe wildfires can cause whitebark pine mortality during all life stages. Conversely, low intensity fires may enhance whitebark pine persistence by removing competing species that are less fire tolerant. However, low intensity fires have been suppressed because of an increase in recreational development and urbanization. Thus, a decline in low intensity fires has reduced whitebark pine persistence by increasing species encroachment while simultaneously, increases in wildfire severity are increasing whitebark pine mortality Categories: Data; Tags: BIOSPHERE, BIOSPHERE, BIOSPHERE, Data, EARTH SCIENCE, All tags...

Surveys were conducted within occupied Lahontan cutthroat trout habitat, as designated by the U.S. Fish and Wildlife Service. Data represent reach-based surveys conducted in accordance with the Lahontan cutthroat trout habitat status assessment (LCTHSA) protocol (USGS). LCTHSA uses a probabalistic sampling design (i.e., Generalized Random Tessellation Stratified), standardized collection of habitat attributes, electronic data capture and management, and integration with remote sensing and geospatially-derived data products.

Hydroacoustic data were collected along 10, randomly-selected, 5-kilometer transects and two cross-basin transects between the US and Canadian shorelines in central Lake Erie during July 2021. Software-generated raw variables were used for calculating estimates of hydroacoustic fish densities presented here in tabular form.

Surveys were conducted between 1968 & 2022 generally for the purposes of assessing fishery statuses in inland lakes. The species in these data represent only a subset of all species present in DNR surveys, and were selected for our study because of relevance to stakeholders and relative vulnerability to the gears used to survey the populations. Categories: Data; Tags: Minnesota, effects of climate change, freshwater ecosystems, inland fishery resources Ecological Implications of Mangrove Forest Migration in the Southeastern U.S. Coastal wetlands purify water, protect coastal communities from storms, sequester (store) carbon, and provide habitat for fish and wildlife. They are also vulnerable to climate change. In particular, changes in winter climate (warmer temperatures and fewer freeze events) may transform coastal wetlands in the northern Gulf of Mexico, as mangrove forests are expected to expand their range and replace salt marshes. The objective of this research was to evaluate the ecological implications of mangrove forest migration and salt marsh displacement. As part of this project, researchers identified important thresholds for ecosystem changes and highlighted coastal areas in the southeastern U.S. (e.g., Texas, Louisiana,...

These spring sites include Salt Spring (USGS Site ID: 360439112094101) and Willow 1 Spring (Site ID: 363357112440801). The MiniSipper auto sampler collects up to 250 five-mL, 0.45 um filtered and acidified water samples. Samples are stored in a 500' teflon tubing sample coil and adjacent water samples are separated by air bubbles (Chapin and Todd, 2012). Water samples are analyzed for a suite of elements using... Categories: Data Data release: early warning indicators for harmful algal bloom assessments in the Illinois River, 2013 - 2020 Harmful algal blooms (HABs) have recently been observed in rivers, including the Illinois River in the Midwest United States. The Illinois River Basin has a history of eutrophication issues, primarily caused by the excessive loading of nitrogen and phosphorus from urban and agricultural sources. Recent events have seen the emergence of cyanobacterial harmful algal blooms in the area. This data release provides early warning indicator (EWI) metrics derived from a continuous chlorophyll concentration dataset obtained from seven water quality monitoring sites along the Illinois River. These metrics include the first-order autoregressive process (Ar1) and the standard deviation (SD) of chlorophyll, which serve as leading...

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.

Vegetation surveys spanned ten years, from July 2008 to January 2018. A total of 5,112 plots were surveyed. Plots were positioned on transects along an elevation gradient and evenly distributed across each site, where possible, to capture spatial variability along elevation and distance gradients. At each plot, percent cover of all plant species, bare ground, and litter as well as average height was visually assessed within a 0.25 m2 quadrat. Total plant cover in a plot could exceed 100 percent due to vegetation layering. Bare ground and litter...

Expert-based fire risk scores derived from field experiences with 49 invasive species in Hawai′i were used to train a machine learning model that predicts expert fire risk scores from among 21 plant traits obtained from literature and databases. The model revealed that just four variables can identify species categorized as higher fire risk by experts with 90% accuracy, while low risk species were identified with 79% accuracy. We then used the predictive model to screen 365 naturalized...
