title: Nutrient and pesticide data collected from the USGS National Water Quality Network and previous networks, 1963-2017

description: The National Water Quality Network (NWQN) for Rivers and Streams includes 111 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program, National Water-Quality Assessment (NAWQA) Project. The NWQN includes 20 large river coastal sites, 41 large river inland sites, 30 wadeable stream reference sites, 10 wadeable stream urban sites, and 10 wadeable stream agricultural sites. In addition to the 111 NWQN sites, 3 large inland river monitoring sites from the USGS Cooperative Water Program are also included in this annual water-quality reporting Web site to be consistent with previous USGS studies of nutrient transport in the Mississippi-Atchafalaya River Basin. This data release provides streamflow, nutrient, pesticide and sediment data collected and analyzed by NWQN and other historical water-quality networks from 1963-2017. Data from this release are presented at the USGS Tracking Water Quality page: http://cida.usgs.gov/quality/rivers/home.

title: Pesticide concentration and streamflow datasets used to evaluate pesticide trends in the Nations rivers and streams, 1992-2012

description: In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitoring has been conducted on streams and rivers throughout the Nation. Outside of the NAWQA project, the USGS also has collected long-term water-quality data to support additional assessments of changing water-quality conditions. These data have been combined to provide insight into how natural features and human activities have contributed to water-quality changes over time in Nations streams and rivers. This USGS data release contains all of the input and output files necessary to reproduce the results from the SEAWAVE-Q pesticide models described in the associated U.S. Geological Survey Scientific Investigations Report (http://dx.doi.org/10.3133/sir20175006). Data preparation for input to the model is also fully described in the above mentioned report.

title: Salinity tolerance of non-native suckermouth armoured catfish (Loricariidae: Pterygoplichthys sp.) from Kerala, India

description: Loricariid catfish of the genus Pterygoplichthys have been introduced in many localities around the world. They are freshwater fishes, but may also use low-salinity habitats such as estuaries for feeding or dispersal. Here we report results of a field survey and salinity-tolerance trials for a population of Pterygoplichthys sp. collected in Kerala, India. In both chronic and acute salinity-tolerance trials, fish were able to withstand salinities up to 12 ppt with no mortality; however, fish transferred to salinities &gt; 12 ppt did not survive. The experimental results provide evidence that non-native Pterygoplichthys sp. are able to tolerate mesohaline conditions for extended periods, and can easily invade the brackish water ecosystems of the state of Kerala. In the light of results of the present study and considering the reports of negative impacts of the species in invaded water bodies, the management authorities may consider taking appropriate action and awareness programmes to prevent the spread of this nuisance aquatic invasive species in Kerala.

title: Independent evolutionary origin for insect deterrent cucurbitacins

description: The cucurbitacins are highly oxygenated triterpenoid, occurring widespread in cucurbitaceous species and in a few other plant families. Iberis spp. are Brassicaceae contain unique feeding inhibitors, cucurbitacins, that are free from insect <em>Pieris rapae</em> and <em>Phyllotreta nemorum</em> which specialized in Brassicaceae. Using de-novo assembled transcriptomics from Iberis amara, gene co-expression analysis and comparative genomics, we unraveled the evolutionary origin of the insect deterrent cucurbitacins in I. amara. Phylogenetic analysis of five oxidosqualene cyclases and heterologous expression allowed us to identify the first committed enzyme in cucurbitacin biosynthesis in I. amara, cucurbitadienol synthase. In addition, two species-specific cytochrome P450s (CYP708A16 and CYP708A15) were identified that catalyse the unique C16 and C22 hydroxylation of the cucurbitadienol backbone, enzymatic steps that have not been reported before. Furthermore, the unlinked genomic position of the cucurbitacin biosynthetic genes in I. amara contrasts with the highly organized gene cluster in the cucurbits. These results reveal that cucurbitacin biosynthesis has evolved convergently via different biosynthetic routes in different families rather than through divergence from an ancestral pathway. This investigation thus provides new insight into the mechanism of recurrent defensive chemical evolution and diversification.

title: Telemetry and reproductive data for Lake Trout in Yellowstone Lake, 2011-2016

description: We initiated a project in 2011 to identify lake-wide movement patterns and spawning areas of invasive lake trout in Yellowstone Lake, WY. We implanted acoustic transmitters in lake trout and established a network of stationary telemetry receivers in Yellowstone Lake. Lake Trout tagged with acoustic transmitters (Vemco V - series) were tracked with stationary acoustic receivers (Vemco VR2W - 69 kHz) from 2011 to 2015. In 2015-2016, we assessed the lake trout maturation cycle and reproductive potential in Yellowstone Lake by sampling lake trout that had been captured in suppression nets and euthanized. A gonadal-somatic index (GSI) was developed to provide an initial index of the lake trout maturation cycle and gonadal development was assessed by histological examination of reproductive tissue samples. These data were used to determine the frequency and pattern of spawning. In addition, a precise estimate of fecundity (mean individual and population) were estimated for egg masses removed from female lake trout.

title: Effects of metals and metal mixtures on aquatic insect communities in experimental streams: cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni), and zinc (Zn)

description: The objectives of the Metals Mixtures Project included developing quantitative models that describe and predict harm or lack thereof to aquatic organisms from multiple metals in mineralized rock drainages. Work consists of data analyses and model development using existing data, and original data from laboratory mesocosm and field studies. This product reports data generated from a series of four experiments conducted over four years, testing the toxicity of several metals with aquatic insect communities that were colonized in the field and then transferred and tested in experimental streams at the Fort Collins Science Center. The results are expected to be of interest to those preparing environmental impact statements to evaluate prospective new or expanding mining activities in relevant geologies, those evaluating remedial strategies for legacy mining operations, mining companies, ecological risk assessors, environmental managers, and other scientists. While the various mixture experiments should be relevant to a variety of mineralized watersheds, one emphasis of the project was to mimic and test conditions relevant to PGE (platinum-group elements) deposits in the North American Mid-Continental Rift/Duluth complex area of Minnesota, Michigan, and Wisconsin.

title: Impact of Hemlock Woolly Adelgid on Canopy Throughfall in Southern New England 2002

description: Exotic insect pests may strongly disrupt forest ecosystems and trigger major shifts on nutrient cycling, structure and composition. Although the immediate impact of these pests are frequently examined as physical disturbances (i.e., defoliation, decline in leaf area, and tree mortality) that initiate changes in ecosystem function, the insects often generate fundamental biochemical and trophic changes in tree canopies that may be equally important in altering ecosystem dynamics. Consequently, investigation of the linkages between canopy-level, ecosystem and environmental impacts may be critical for a thorough understanding of functional, structural, and compositional changes resulting from pest infestation. We sought to establish a better understanding of these linkages for the hemlock woolly adelgid (HWA), which is devastating hemlock forests in an expanding region across eastern North American and has the potential to eliminate this long-lived and extremely shade-tolerant species across much of its range. We examined the impact of the adelgid on hemlock needle chemistry and epiphytic microorganisms, litter production, and shoot growth in stands differing in their levels of infestation and linked these to shifts in canopy nutrient cycling and stand and landscape dynamics. HWA initiated major changes in canopy biomass and distribution. Whereas uninfested trees exhibit a decline in canopy biomass from the center to the periphery and a positive correlation between total needle litter and estimated biomass, infested trees support predominantly woody biomass, have significantly less total canopy biomass, produce less new foliage and exhibit no correlation between litter and canopy biomass. Foliar %N was strongly influenced by needle age and the level of infestation and was highest in young foliage supporting the highest densities of HWA. Foliar %C was unaffected by HWA or foliar age. Epiphytic microorganisms on hemlock needles exhibited little variation in abundance within canopies, but bacteria, yeasts and filamentous fungi were significantly more abundant on medium and heavily infested than uninfested trees. Throughfall chemistry, quantity, and spatial pattern were strongly altered by HWA. Beneath uninfested trees throughfall exhibits a strong gradient, decreasing in volumes from the canopy periphery to the trunk. Beneath infested trees the amount of throughfall is greatly increased, spatially unpatterned and characterized by higher concentrations of nitrogen compounds, carbon and cations. Across the southern New England landscape there is a strong south to north gradient of decreasing tree and sapling mortality and understory compositional change that correspond to the duration of infestation. Regionally, black birch, a nitrogen demanding species that is competitively enhanced by increasing nitrogen availability is profiting most from hemlock decline.

title: Co-Creating a Healthier NHS: Survey Data, 2017-2020

description: The aim of this project was to work with employees within a select number of NHS Trusts to co-design, deliver, and evaluate a series of mental health and wellbeing interventions for staff in these organisations. The project began with a cross-organisational survey to understand the working conditions and psychological wellbeing of employees, followed by a series of interviews and focus groups with staff. This led to the development of a wellbeing smartphone app and associated toolkit. 6-8 months following intervention dissemination, the survey and interviews were re-distributed. Within this dataset, quantitative data collected from organisations pre-and-post intervention is presented. The survey data consists of the management standards indicator tool, perceived stress, Warwick Edinburgh Mental Wellbeing Scale, Utrecht Work Engagement Scale, and hour disparity (i.e. difference between contracted hours and average hours worked each week), as well as whether the data was pre- or post-intervention.

title: Implementation of conservation tillage and cover crops in the Chesapeake Bay watershed, 1985 to 2012

description: Conservation tillage practices and cover crops are used throughout the Chesapeake Bay watershed to reduce soil loss and improve water quality. Implementation of these Best Management Practices (BMPs) were reported to the Chesapeake Bay Program (CBP) by each state in the watershed (New York, Pennsylvania, Maryland, Delaware, West Virginia, and Virginia). Estimates of acres of implementation per CBP land river modeling segment for the years 1985 through 2014 were provided to the U.S. Geological Survey. These data were distributed to agricultural land use cells in the National Land Cover Dataset (NLCD) dataset and summed for National Hydrography Dataset (NHD) Plus version 1 catchments to provide estimates of implementation at spatial scales commonly used for modeling purposes for the years 1985, 1992, 2002, and 2012 for conservation tillage, as well as 2002 and 2012 for cover crops.

title: Bull Trout (Salvelinus confluentus) Telemetry and Associated Habitat Data Collected in a Geodatabase from the Upper Boise River, Southwestern Idaho

description: Bull trout (Salvelinus confluentus), listed as threatened under the Endangered Species Act, are among the more thermally sensitive of coldwater species in North America. The Boise River upstream of Arrowrock Dam in southwestern Idaho (including Arrowrock Reservoir) provides habitat for one of the southernmost populations of bull trout. The presence of the species in Arrowrock Reservoir poses implications for dam and reservoir operations. From 2011 to 2014, the Bureau of Reclamation and the U.S. Geological Survey collected fish telemetry data to improve understanding of bull trout distribution and movement in Arrowrock Reservoir and in the upper Boise River tributaries. The U.S. Geological Survey compiled the telemetry (fish location) data, along with reservoir elevation, river discharge, precipitation, and water-quality data in a geodatabase. The geodatabase includes metadata compliant with Federal Geographic Data Committee content standards. Reclamation plans to incorporate the data in a decision-support tool for reservoir management.
