10-year (2003-2012) bird and vegetation data collected at wind facilities in North Dakota and South Dakota 10-year (2003-2012) bird and vegetation data collected at wind facilities in North Dakota and South Dakota
This data release contains eight datasets that represent the entirety of the data collected for a study that examined breeding-bird densities in native mixed-grass prairie from 2003 to 2012 at and adjacent to wind facilities in North Dakota and South Dakota, USA. Data were collected to determine breeding-bird density per 100 hectares (ha) by distance bands from turbines and by excluding...
Pre-mining environmental baseline characterization of the Aynak copper deposit: 2019 field season Pre-mining environmental baseline characterization of the Aynak copper deposit: 2019 field season
These data include geochemical analyses of rock, mine waste, sediment, and soil samples collected from the Aynak copper deposit, Logar Province, Afghanistan in 2019. In addition, these data include geochemical analyses of water samples collected from the Aynak copper deposit, Logar Province, Afghanistan in 2019.
Spatial and temporal surveys of salmon eDNA in Seattle urban creeks, Washington, 2018 - 2020 Spatial and temporal surveys of salmon eDNA in Seattle urban creeks, Washington, 2018 - 2020
The data support a study that surveyed the spatial and temporal distribution of salmon eDNA in Seattle urban creeks, Washington, 2018 - 2020. The metadata represent qPCR quantification cycle (Cq) values for Chinook salmon, coho salmon, and coastal cutthroat trout assays performed on water samples collected on specific days at specific sites on Thornton Creek, Taylor Creek, and Mapes...
Proximal and distal factors associated with the decline in secondary invertebrate prey production in the Colorado River, Glen Canyon, Arizona. Proximal and distal factors associated with the decline in secondary invertebrate prey production in the Colorado River, Glen Canyon, Arizona.
Using a bioenergetic model, demographic data for the Rainbow Trout (Oncorhynchus mykiss) population were compiled and used to estimate total prey consumption in the Colorado River, Glen Canyon , AZ. Additionally, other data including invertebrate diet, drift, and benthic measurements were used to make generalized estimates of daily production rates for the most common benthic...
Histochemical study of nitrogen-transfer endosymbiosis Histochemical study of nitrogen-transfer endosymbiosis
Plant roots have the best-understood mutualisms with microbes, but leaf and bract cell endosymbiosis have not been previously reported. Leaf and bract cells of more than 30 species in 18 families of seed plants were surveyed for the presence of intracellular bacteria and several experiments were designed to find and analyze nutrient exchanges between bacteria and plant cells. This...
Surface water estimates for a complex study site derived from traditional and emerging methods Surface water estimates for a complex study site derived from traditional and emerging methods
These data describe the area of different habitat covered in water as determined via three approaches: manual surveys, digitized aerial imagery, and categorization of the newly available dynamic surface water extent dataset derived from satellite imagery. These data support a scientific publication.
