Publisher's Synopsis
Grasshoppers and crickets are used widely in ecological, cytogenetic and bio-acoustic research, and have recently become important subjects in evolutionary biological studies. They are also increasingly used in the field of conservation as indicators of undisturbed habitat.;This boxed set of two compact disks is a companion to a reference work on the songs of grasshoppers and crickets which covers Europe as far as the eastern borders of Germany, Austria and Italy, but nevertheless includes the vast majority of species found in Eastern Europe. The disks include 341 excerpts from the recorded songs of 170 species of bush-cricket, true cricket, mole-cricket and grasshopper - all the common Western European species and most of the rarer ones - as well as four cicadas, two toads and five birds. The commentary is by David R. Ragge, one of the co-compilers.
