Flea abundance and body condition data for black-tailed prairie dogs on sites treated and not treated with "FipBit" fipronil pellets, South Dakota, 2018-2020 Flea abundance and body condition data for black-tailed prairie dogs on sites treated and not treated with "FipBit" fipronil pellets, South Dakota, 2018-2020
Flea abundance and body condition data for black-tailed prairie dogs on sites treated and not treated with "FipBit" fipronil pellets. We sampled prairie dogs at Conata Basin, Buffalo Gap National Grassland, and Badlands National Park, South Dakota, USA. We sampled fleas from live-trapped prairie dogs during June-October 2018, May-October 2019, and July-August 2020. Prairie dogs were...
2006-2009 Phytoplankton data collected in the Mississippi River Navigation Pools 8, 13, and 26 2006-2009 Phytoplankton data collected in the Mississippi River Navigation Pools 8, 13, and 26
The dimensions of each organism were measured with a Whipple grid and the biovolume was estimated using the simplest geometric shape (e.g., cylinder, cone, sphere, etc.) that best fit the shape of each taxon. Shapes were assigned according to Hillebrand et al. (1999). Biovolume was calculated for the first five organisms/counting units of each taxon identified in a sample. The average...
Grass Carp (Ctenopharyngodon idella) egg capture data from tributaries to western Lake Erie, 2015-2020 Grass Carp (Ctenopharyngodon idella) egg capture data from tributaries to western Lake Erie, 2015-2020
The data includes dates, places, and times of sampling events for eggs and larvae of invasive Grass Carp (Ctenopharyngodon idella) in tributaries to Lake Erie between 2015 and 2020. Reference data on locations and dates sampled, gears used, and effort are included. Developmental stages for a subset of undamaged, fertilized eggs are provided. Tables include common fields to allow for...

Nutrient Load Data used to Quantify Regional Effects of Agricultural Best Management Practices: An application of the 2012 SPARROW models for the Midwest, Northeast, and Southeast United States Nutrient Load Data used to Quantify Regional Effects of Agricultural Best Management Practices: An application of the 2012 SPARROW models for the Midwest, Northeast, and Southeast United States
Nitrogen and phosphorus losses from agricultural areas have impacted the water quality of downstream rivers, lakes, and oceans. As a result, investment in the adoption of agricultural best management practices (BMPs) has grown but assessments of their effectiveness at large spatial scales have been sparse. This study applies regional Spatially Referenced Regression On Watershed...
