Basic information
Sample name: Kansas Agricultural Experiment Station (Kentucky bluegrass)
Reference: D. A. Wilbur and R. F. Fritz. 1940. Grasshopper populations (Orthoptera, Acrididae) of typical pastures in the Bluestem region of Kansas. Journal of the Kansas Entomological Society 13(3):86-100 [ER 2164]
Geography
Country: United States
State: Kansas
Coordinate: 39° 12' N, 96° 36' W
Coordinate basis: based on nearby landmark
Geography comments: none given (the Station was in Manhattan, basis of coordinate, and is apparently not the same as Konza Prairie Biological Station)
Environment
Habitat: temperate savanna
Substrate: ground surface
Habitat comments: "The area considered as the Kentucky bluegrass pasture started out with a fine stand of this grass but the drouth of 1934 practically eliminated it... The Kentucky bluegrass has scarcely gained during the past five years"
Methods
Life forms: orthopterans
Sampling methods: no design,sweep nets
Sample size: 1002 individuals
Years: 1933 - 1939
Sampling comments: "Each year the collections were started during April... and were continued throughout the growing season... Semi-weekly collections were intended but occasionally rains interfered... collecting was done by means of a specially constructed, long-handled, square net, the mouth of which was one square foot in area. Twenty-five sweeps of this net in each plot, each sweep covering about three feet, constituted a collection"
