CBS04 Sweep sample data: prey estimates for Grasshopper Sparrows on Konza Prairie


This data set includes data on the contents of sweep samples. We collected sweeps in select years during May, June, and/or July in 3 locations on each of the focal watersheds. Sweeps were 80m long and centered at veg points. Data consist of information about the sampling events, and sample wet mass, edible mass (combined mass of selected orders listed below). Additionally, the dataset includes the number of individuals in each of a series of size categories, total N, and mass (in grams) of the following groups: Tettigoniidae, Acrididae, other Orthoptera, Gryllidae, Odonata, Ephemeroptera, Coleoptera, Hymenoptera, Lepidoptera, Arachnida, Hemiptera, Neuroptera, Diptera, Phasmatidae, Mantidae, and “other”.
