Geographical variation in Isophya camptoxypha (Orthoptera, Tettigoniidae) male songs: Part 1—Solo performance across different microphones

Through the analysis of male-song characteristics in Isophya camptoxypha (Fieber), a Curve-tailed plump bush-cricket species prevalent in the highlands of the Alps and the Carpathians, this study establishes that acoustic signals not only serve for species identification among closely related counterparts but also contribute to biogeographical assumptions and constructions. The investigation delves into the formation of a relict locality on Stinka Mountain, situated at the junction of two Carpathian biogeographical regions. Additionally, the research explores the implications of using different types of microphones for bioacoustic measurements.
