Habitat requirements of the endangered heath bush-cricket Gampsocleis glabra (Orthoptera, Tettigoniidae) in an isolated population

摘要: Steppes and xerothermic grasslands are hotspots of biodiversity, but threatened by habitat destruction fragmentation. The heath bush-cricket, Gampsocleis glabra, is considered to be a specialist habitats appears in national red lists as species several European countries. goal the current research was determine requirements G. glabra an isolated patch Poland, at northern edge its range. By comparing composition plant vegetation architecture vacant occupied sites summers 2018 2019, it found that this population still maintained strict specialisation for xerothermofilous Festuco-Brometea community. On contrary previous studies, however, Stipa-type grasses were not essential occurrence majority areas based on Brachypodium pinnatum. physiognomy communities crucial abundance stridulating males, which showed preference dense 10 cm high. characteristics patches males females did differ significantly. study endangered Orthoptera could serve prelude restoration similar locations before becomes extinct. This may also underpin development global conservation strategy glabra.
