Serendipity versus proactive search of elusive species - the Encounter Predictability Scorecard (EPS), a new customizable tool for field researchers
Full text linkSince field research requires a lot of effort, time, economic and resource investment, it necessitates fact-based tools for a sound preliminary evaluation of the actual possibility to achieve its objective. Such a tool, the Encounter Predictability Scorecard (EPS), is here described for the first time. The rediscovery of the endemic Orthopteran Uromenus annae proved that field research is performed under strong biases including blind faith in previous scientific literature, and expectations about the biology and ecology of the target species. U. annae escaped field researches in the documented localities, and was rediscovered serendipitously in two new unrelated locations. This casts doubt on the capacity of field researchers to assess, even in general terms, the possibility of success of field expeditions. We conceived a method inspired by the performance management tools from the world of corporate strategy: scorecards. The most famous among closed-choice, qualitative-quantitative checklists, is the Balanced Scorecard, based on original work from the late 1980’s. We adapted those methods to the constraints of field research, and field-tested in a retrospective way for the search of U. annae. The EPS is freely available as a digital spreadsheet, and can be tested and customised at any time. Although in its infancy, the EPS looks like a promising operational tool to help saving time and money, and to identify which objectives and organizational setups are more promising. Besides providing a clearer, more rational basis for operational decisions, the straightforward compilation of an EPS may also mitigate the impact of cognitive biases

Full text linkLa scoperta fortuita di Acheta pantescus Massa, Cusimano, Fontana, Brizio, 2022, nata dall’osservazione di un canto di grillo non riconosciuto durante la revisione di registrazioni di monitoraggio acustico passivo (PAM), ha rivelato il potenziale dei registratori non supervisionati come strumenti per la valutazione della diversità degli ortotteri. Questo studio, basato su una campagna PAM notturna di un mese in due località pugliesi, copre le problematiche del riconoscimento delle specie di ortotteri mediante mezzi bioacustici e delinea un flusso di lavoro di analisi e diagnosi per paesaggi sonori contestati, con particolare riferimento a registrazioni di media qualità (frequenza di campionamento di 24 kHz, banda 0 kHz - 12 kHz), scelte come il miglior compromesso tra qualità e capacità di archiviazione. Al prezzo di un significativo impiego di tempo, il metodo si è dimostrato adatto per una valutazione preliminare della diversità degli ortotteri a canto notturno. I risultati includono diverse lezioni apprese, un elenco delle specie osservate e alcune nuove osservazioniThe fortuitous discovery of Acheta pantescus Massa, Cusimano, Fontana, Brizio, 2022, born from the observation of an unknown cricket song during the review of passive acoustic monitoring (PAM) recordings, disclosed the potential of unsupervised recorders as tools for the assessment of orthopteran diversity. This case study, based on a one-month, nightly PAM campaign in two Apulian locations, covers the issues of orthopteran species recognition by bioacoustical means and outlines an analysis and diagnosis workflow for contested soundscapes, with special reference to the medium-quality record settings (24 kHz sampling frequency, 0 kHz - 12 kHz band), chosen as the best compromise between quality and storage capacity. At the price of substantial labour, the method proved suitable for a preliminary assessment of the diversity of the night-singing orthoptera. Results include several lessons learned, a list species observed and some novel observation
