Book Description
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.

Book Description
At a time when night-singing insects have slipped beyond our notice—indeed, are more likely to be heard as NatureSounds than in a backyard—John Himmelman seeks to reconnect us to creatures whose songs form a part of our own natural history. On warm summer evenings, night-singing insects produce a whirring, chirping soundscape—a calming aural tapestry celebrated by poets and naturalists for millennia. But “cricket radio” is not broadcast for the easy-listening pleasure of humans. The nocturnal songs of insects are lures and warnings, full of risks and rewards for these tiny competitive performers. What moves crickets and katydids to sing, how they produce their distinctive sounds, how they hear the songs of others, and how they vary cadence, volume, and pitch to attract potential mates, warn off competitors, and evade predators is part of the engaging story Cricket Radio tells. Himmelman’s narrative weaves together his personal experiences as an amateur naturalist in search of crickets and katydids with the stories of scientists who study these insects professionally. He also offers instructions for bringing a few of the little singers into our homes and gardens. We can, Himmelman suggests, be reawakened to these night songs that have meant so much to the human psyche. The online insect calls that accompany this colorfully illustrated narrative provide a bridge of sound to our past and to our vital connection with other species.

Book Description
Orthoptera is one of the most important and interesting Orders of the Class Insecta. They include grasshoppers and crickets that have a fundamental role in many terrestrial ecosystems. In this complete and updated publication all the 382 taxa (species and subspecies) of Orthoptera nowadays known from Italy are treated; 162 of these are endemic! Unfortunately, as well as for other groups of organisms, also orthopterans have many species suffering from maximum degree of threat, according to the Red List of Threatened Species compiled by the International Union for Conservation of Nature (IUCN). Therefore, Grasshoppers & Crickets of Italy is very important also from a conservation point of view; it allows to recognize the endangered species for planning interventions to safeguard them. This new volume is an absolutely innovative tool in the field of nature handbooks. The authors have succeeded in realizing a text with a new and appealing graphic design, easy to consult, full of photos of morphological details useful to identify the species also by non-experts. Furthermore, very useful for the field work are the maps of the distribution areas, detailed at provincial level, for each species. This book will be useful not only for orthopterists, but also for young entomologists who will be able to measure their ability in identifying species, for agricultural technicians and for all nature and entomology lovers. Gli Ortotteri sono uno degli ordini più importanti e interessanti della grande classe degli insetti. Essi comprendono grilli e cavallette, che rivestono un ruolo fondamentale negli ecosistemi terrestri. In questa pubblicazione completa e aggiornata sono trattati tutti i 382 taxa (specie e sottospecie) di Ortotteri conosciuti oggi in Italia; di questi ben 162 risultano endemici, cioè esclusivi del nostro Paese! Purtroppo, come per altri gruppi di organismi, anche tra gli Ortotteri figurano specie al massimo grado di minaccia, secondo la lista rossa stilata dall’IUCN. Grasshoppers & Crickets of Italy è utile, quindi, anche dal punto di vista conservazionistico, per conoscere le specie in pericolo e attuare interventi in grado di garantirne la tutela. Questa nuova guida è uno strumento assolutamente innovativo nel campo dei manuali naturalistici di campagna. Si tratta di un volume con una veste grafica moderna e accattivante, di facile consultazione, ricchissimo di immagini di particolari morfologici utili all’identificazione delle specie anche da parte di non esperti. Utilissime, per il lavoro sul campo, anche le mappe degli areali di distribuzione, dettagliate a livello di singola provincia. Una guida utile, non solo agli ortotterologi, ma anche ai giovani entomologi che vorranno misurarsi con la loro capacità di identificare le specie, ai tecnici agricoli e a tutti gli amanti della natura e dell’entomologia.

Book Description
Bat detector surveys are carried out by ecological consultants, researchers, conservationists and hobbyists. Understanding and categorising non-bat sounds in surveys offers the potential of knock-on benefits for informing development projects (e.g. other important records discovered within a site), as well as the possibility of associated conservation benefits. In recent years the number of people carrying out these surveys and recording calls with bat detectors has grown considerably. These surveys often generate vast amounts of audio recordings, resulting in the heavy workload associated with completing the sound analysis and reporting process. Those carrying out analysis can be distracted, intrigued or delayed owing to the occurrence of recordings that are unfamiliar and not identifiable to them. These recordings can relate to ‘difficult to ID’ bat species, but also, often, sounds not related to bats. This can be especially true when noise triggers such as insects, small mammals or birds look like bat-related noise. Therefore, only knowing what bats sound like is not enough. It is extremely useful to know what other sources of noise look and sound like within the same soundscape. This resource will help bat workers, in whatever environment they are in, to be more confident in recognising, categorising and dismissing other sounds. The book includes a substantial downloadable sound library (.wav format) that readers can listen to by ear or process through sound analysis software. Is That a Bat? also caters for sounds that are also heard by ear alone, in the field, during the hours of darkness. These scenarios often have bat surveyors intrigued or confused as to what they are listening to. Occasionally, knowing what these sounds are could be important, or at the very least, of interest. The first chapter caters for the subject overall, including suggestions from the author as to why the subject matter is of value. It also discusses bat-related calls (including social calls) with a view to offering comparisons against the other sources of sound discussed in separate chapters. Continuing through the book, there are chapters covering the following: small mammals; amphibians; insects; birds; electrical/mechanical noise; and other noise/nuisances. Within each chapter there are sub-sections about bat detector recorded sound, sound by ear, as well as advice on techniques and methods to reduce or increase the likelihood of recording other sounds. The book concludes with associated appendices, including a ‘Problem Solving Key’ to help those encountering an unfamiliar sound to narrow it down to the likely source. With technology advancing at pace, the technical ability of the analyst is of huge importance. With a wider perspective and more knowledge, those responsible for interpreting field encounters can be more confident when making decisions about sources of sound. Apart from that, ‘knowing stuff’ makes the job far more interesting and gives the bat worker a greater appreciation of the natural world within which they are working.
