Most of the 170 species of grasshoppers and crickets included in this book can be identified instantly by their songs – and often more reliably than from their appearance. Orthopterans have recently become important subjects in evolutionary biological studies and are also increasingly used in the field of conservation as indicators of undisturbed habitat. The book comprises the following chapters: Introduction; Acoustic Methods; Sound Production and Reception of European Orthoptera; The Nature and Function of the Songs; The Value of the Songs in Taxonomy and Identification; Key to the singing Orthoptera of Western Europe, based primarily on their Songs; and other Animal Sounds that could be confused with Orthoptera Songs – illustrated with over 1600 oscillograms; three Appendixes (Check-list of the species included; Summary of Nomenclatural Changes; Data for the Song Recordings); Glossary; References; Index to Vernacular Names; and General Index.

'Wisdom Songs' is a collection of five Centuries on the Holy Name, the Song of Songs, Holy Wisdom, the Mysteries of Glory and the Wisdom of Stillness.This ancient monastic wisdom genre was much loved by the desert fathers and hermits of old, nourishing saints and seers for hundreds of years. The crises of the environment, informational technology, interfaith and gender issues all call for wisdom. So it is no surprise to find orthodox wisdom offering ancient remedies to renew the living tradition in order to address the most urgent needs of our time. Priest-monk Silouan lives in the Monastery of St Antony and St Cuthbert, a hermitage within the Romanian jurisdiction of the Orthodox Church. He lives a life of prayer, silence, liturgy and work in the ancient tradition of Orthodox monasticism.
