Habitat associations of grasshoppers (orthoptera: Acrididae) in the heterogeneous cedar glade landscape of the central basin of tennessee

Abstract

Grasshopper communities were sampled in three associated habitats of the Central Basin of Tennesee: cedar glades, xeric limestone prairies, and cedar hardwood forest. Twenty-five grasshopper species were collected across all three habitats. Eleven species were found in the cedar glades, 12 species were collected in the xeric limestone prairies, and six species were collected from the cedar-hardwood forests. A Principal Component Analysis of the resulting species lists indicated that grasshopper community composition differed significantly between each habitat. Four new state records for Tennessee were documented during this survey. An annotated species list is presented.
