Habitat loss, together with less obvious land-use changes such as intensified farming practice, can have significant adverse impacts on biodiversity. An important factor in determining the ability of species to cope is their potential sustain a populations network by dispersal across landscape. quality and structure are particularly for surface-dwelling low abilities, amphibians. To assess this ecological function, ponds coastal typically rural area northern France were surveyed amphibians...

Forest restoration requires monitoring to assess above‐ and belowground communities, which is challenging due practical resource limitations. Ecological acoustic survey methods––also known as “ecoacoustics”––are increasingly available provide a rapid, effective, non‐intrusive means of biodiversity. Aboveground ecoacoustics widespread, but soil has yet be utilized in despite its demonstrable effectiveness at detecting soniferous meso‐ macrofauna. This study applied ecoacoustic tools indices...

Abstract Ecoacoustics, the study of environmental sound, is a rapidly growing discipline offering ecological insights at scales ranging from individual organisms to whole ecosystems. Substantial methodological developments over last 15 years have streamlined extraction information audio recordings. One widely used set methods are acoustic indices, which offer numerical summaries spectral, temporal and amplitude patterns in Currently, specifics each index's background, methodology soundscape...

Effective monitoring of rare and declining species is critical to enable their conservation, but can often be difficult due detectability or survey constraints. However, developments in acoustic recorders are enabling an important new approach for improved that especially applicable long-term studies, use environments with cryptic species. Bioacoustic data may effectively analysed within occupancy modelling framework, as presence/absence determined, repeated events accommodated. Hence, both...

Abstract Forest restoration requires monitoring to assess changes in above- and below-ground communities, which is challenging due practical resource limitations. With emerging sound recording technologies, ecological acoustic survey methods—also known as ‘ecoacoustics’—are increasingly available. These provide a rapid, effective, non-intrusive means of biodiversity. Above-ground ecoacoustics widespread, but soil has yet be utilised despite its demonstrable effectiveness at detecting meso-...

Capsule: Automated acoustic recording can be used as a valuable survey technique for Capercaillie Tetrao urogallus leks, improving the quality and quantity of field data this endangered bird species. However, more development work testing against traditional methods are needed to establish optimal working practices.Aims: This study aims determine whether vocalizations recognized in lek recordings, automated using readily available software, number calls resulting varies with location,...

Abstract Freshwater conservation is vital to the maintenance of global biodiversity. Ponds are a critical, yet often under‐recognized, part this, contributing overall ecosystem functioning and diversity. They provide habitats for range aquatic, terrestrial, amphibious life, including rare declining species. Effective, rapid, accessible survey methods needed enable evidence‐based action, but freshwater taxa viewed as “difficult”—and few specialist surveyors available. Datasets on ponds...
