This dataset documents results from 1,041 groundwater samples collected during 1986‒2015 from 16 geologic units in Pennsylvania associated with 25 or more groundwater samples with activities or concentrations of radon-222. Radon-222 is hereafter referred to as “radon.” These 16 geologic units were evaluated in an effort to identify variations in radon concentrations and to classify potential radon exposure from groundwater and indoor air. This dataset was developed for the Pennsylvania Environmental Public Health Tracking (PAEPHT) Program to describe the spatial distribution of radon concentrations in groundwater in Pennsylvania and to illustrate data gaps that exist throughout the State. The PAEPHT Program is part...

This dataset describes the storm event mean concentrations and loads of total and dissolved forms of phosphorus and nitrogen from paired samples collected in the control and test catchment during the calibration and treatment phase of a leaf removal study in Madison, Wisconsin, USA. Samples were collected in spring 2013 through fall 2015 and are parsed by season where spring represents April – May, summer represents June – September and fall represents October – November. Measured weather parameters for each sampled storm event are also described. These data are interpreted in a journal article published in Science of the Total Environment.

The U.S. Geological Survey (USGS) and the National Park Service (NPS) have collaborated on monitoring the chloride flux in the major rivers of Yellowstone National Park by periodically sampling the rivers and analyzing chloride concentrations in discrete water samples since the 1970's. However, restrictions of winter travel, great distances between sites, and sampling and analytical costs have limited collection to approximately 28 samples per site annually. Electrical conductivity data can be used as a proxy for chloride concentrations in many of the major rivers of Yellowstone National Park. Electrical conductivity is a measure of the ability of water to pass an electrical current, and it is affected by the presence...

MethodsStudy area: Our initial study area included the entire globe. We began with a seamless grid of cells with a resolution of 0.5 degrees (i.e., ~50 km at the equator). Next, we created polylines representing coastlines using SRTM (Shuttle Radar Topographic Mission) v4.1 global digital elevation model data at a resolution of 250 m (Reuter et al. 2007). We used these coastline polylines to identify and retain cells that intersected the coast. We excluded 192,227 cells that did not intersect the coast. To avoid cells with minimal potential coastal wetland habitat, we used the coastline data to remove an additional 1,056 coastal cells that contained less than or equal to 5% coverage of land. We also removed 176...

This U.S. Geological Survey (USGS) Data Release represents geospatial and tabular data on irrigation water use in Kansas. The data release was produced in compliance with open data requirements. The dataset consists of 3 separate items with similar attributes aggregated to different geographic extents: 1. Kansas counties; 2. Kansas regional planning areas used in the Kansas Water Plan; and 3. Kansas irrigation water-use analysis regions. Reported 2014 water withdrawn for irrigation, acres irrigated, and application rates along with the published application rate statistics from the previous 4 years (2010–13) are shown with the 2014 statistics and are used to calculate a 5-year average. The 2014 annual total...

This data was generated from a study in which five experiments were conducted that tested whether and how dissolved chemicals might assist food recognition in two filter-feeding fishes, the silver (Hypophthalmichthys molitrix) and the bighead carp (H. nobilis). The buccal-pharngeal pumping (BPP), a behavior in which fish pump water into their buccal cavities, was observed in both silver and bighead carps after exposure to a a variety of food filtrates and mixtures. In addition, occlusion experiments to determine if the olfactory sense has a very important, but not exclusive, role in bigheaded carp feeding behaviors were conducted.

Interactions and feedbacks between abundant surface waters and permafrost fundamentally shapelowland Arctic landscapes. Sublake permafrost is maintained when the maximum ice thickness (MIT) exceedslake depth and mean annual bed temperatures (MABTs) remain below freezing. However, decliningMIT since the1970s is likely causing talik development below shallow lakes. Here we show high-temperature sensitivity towinter ice growth at the water-sediment interface of shallow lakes based on year-round lake sensor data.Empirical model experiments suggest that shallow (1m depth) lakes have warmed substantially over the last30years (2.4°C), withMABT above freezing5 of the last 7years.This is incomparison to slower ratesofwarming...

In this first worldwide synthesis of in situ and satellite-derived lake data, we find that lakesummer surface water temperatures rose rapidly (global mean = 0.34°C decade1) between 1985 and2009. Our analyses show that surface water warming rates are dependent on combinations of climate andlocal characteristics, rather than just lake location, leading to the counterintuitive result that regionalconsistency in lake warming is the exception, rather than the rule. The most rapidly warming lakes are widelygeographically distributed, and their warming is associated with interactions among different climatic factors—from seasonally ice-covered lakes in areas where temperature and solar radiation are increasing whilecloud...

Rapid expansion of cropland threatens grassland ecosystems across western North America and broad-scaleplanning can be a catalyst motivating individuals and agencies to accelerate conservation. Sprague’s Pipit(Anthus spragueii) is an imperiled grassland songbird whose population has been declining rapidly in recent decades.Here, we present a strategic framework for conservation of pipits and their habitat in the northern GreatPlains.We modeled pipit distribution across its million-km2 breeding range in Canada and the U.S.We describefactors shaping distribution, delineate population cores and assess vulnerability to future grassland losses. Pipitsselected landscapes with a high proportion of continuous grassland...

Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions immediately south of a focal landscape, to maintain or increase aboveground biomass, productivity, and species and functional diversity. We modeled forest change with the LANDIS-II forest simulation model for 100 years (2000–2100) at a 2-ha cell resolution and five-year time steps within two landscapes in the Great Lakes region...

The influence of recent climate change on the world’s biota has manifested broadly, resulting in latitudinal range shifts, advancing dates of arrival of migrants and onset of breeding, and altered community relationships. Climate change elevates conservation concerns worldwide because it will likely exacerbate a broad range of identified threats to animal populations. In the past few decades, grassland birds have declined faster than other North American avifauna, largely due to habitat threats such as the intensification of agriculture. We examine the effects of local climatic variations on the breeding performance of a bird endemic to the shortgrass prairie, the Lark Bunting (Calamospiza melanocorys) and discuss...

Playa wetlands on the west-central Great Plains of North America are vulnerable to sediment infilling from upland agriculture, putting at risk several important ecosystem services as well as essential habitats and food resources of diverse wetland-dependent biota. Climate predictions for this semi-arid area indicate reduced precipitation which may alter rates of erosion, runoff, and sedimentation of playas. We forecasted erosion rates, sediment depths, and resultant playa wetland depths across the west-central Great Plains and examined the relative roles of land use context and projected changes in precipitation in the sedimentation process. We estimated erosion with the Revised Universal Soil Loss Equation (RUSLE)...

Article Abstract: Although riparian and aquatic ecosystems make up a small fraction of the area in arid and semi-arid lands, they are critical for the survival of desert life. There are, however, few compendia of efforts to define the quantity of water needed to maintain these ecosystems and understand the risks and stressors to them. Through our analysis we found that 62% of the rivers examined in the deserts of the U.S. and Mexico have had just one study over the past four decades and 67% of studies used qualitative methods. Furthermore, only one-third of the 312 species catalogued in our work have been studied more than once and only 5% have been considered five or more times. The most common risks or stressors...

Our primary goal for this dataset was to obtain the population and number of dwellings at the finest common scale possible. Because the Canadian government first began to collect the pertinent census information at our desired scale in 2006, we used 2006 as the baseline for this product on the Canadian CCE. However, because (1) U.S. Census takes place every 10 years, and (2) our desired baseline date for the protocol was 2000, the census 2000 blocks were used on the U.S. CCE. This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant at the...
