Abstract The rise of passive acoustic monitoring and the rapid growth in large audio datasets is driving development analysis methods that allow ecological inferences to be drawn from data. Acoustic indices are currently one most widely applied tools ecoacoustics. These numerical summaries sound energy contained digital recordings relatively straightforward fast calculate but can challenging interpret. Misapplication misinterpretation have produced conflicting results led some question their...
Abstract Acoustic indices are increasingly employed in the analysis of soundscapes to ascertain biodiversity value. However, conflicting results and lack consensus on best practices for their usage has hindered application conservation land‐use management contexts. Here we propose that sensitivity acoustic ecological change fidelity communities negatively impacted by signal masking. Signal masking can occur when responses taxa sensitive effect interest masked less‐sensitive groups, or target...
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...
Acoustic monitoring has proven to be an effective tool for biotic soundscapes in the marine, terrestrial, and aquatic realms. Recently it been suggested that could also method soil soundscapes, but used very few studies, primarily temperate polar regions. We present first study of using passive acoustic tropical forests, a novel analytical pipeline allowing use in-situ recording with minimal disturbance. found significant differences index values between burnt unburnt forests indications...
Abstract Long‐term biodiversity monitoring is needed to track progress towards ambitious global targets reduce species loss and restore ecosystems. The recent development of cheap robust acoustic recording devices offers a cost‐effective means gathering standardised long‐term datasets. Accounting for sources bias in ecological research fundamental part the study design process. To highlight this issue context terrestrial ecoacoustic monitoring, here we collate discuss arising from (i)...
Abstract Estimation of avian biodiversity is a cornerstone measure ecosystem condition. Surveys conducted using autonomous recorders are often more efficient at estimating diversity than traditional point‐count surveys. However, there limited research into the optimal temporal resolution for sampling—the trade‐off between number samples and sample duration when sampling survey window with fixed effort—despite allowing easy repeat compared to methods. We assess whether additional coverage...
Abstract Conservation translocations are an important tool in wildlife management, but monitoring of has traditionally suffered from a lack techniques for effective post‐release monitoring. Increasing understanding movements is vital improving the success translocations, few methods exist to efficiently monitor highly mobile and cryptic species post‐release. We present novel approach using dynamic occupancy modelling combination with data derived autonomous acoustic recording units behaviour...
Abstract Passive acoustic monitoring can be an effective method for species, allowing the assembly of large audio datasets, removing logistical constraints in data collection and reducing anthropogenic disturbances. However, analysis datasets is challenging fully automated machine learning processes are rarely developed or implemented ecological field studies. One greatest uncertainties hindering development these methods spatial generalisability—can algorithm trained on from one place used...
Abstract Estimation of avian biodiversity is a cornerstone measure ecosystem condition, with turnover in community composition underpinning many studies land-use change tropical forests. Surveys conducted using autonomous recorders have been frequently found to be more efficient than traditional point-count surveys. However, there has limited research into optimal survey duration, despite recordings allowing for repeats short-duration surveys relative ease comparison methods. We use an...
Abstract PAM has proven to be an effective tool for monitoring biotic soundscapes in the marine, terrestrial, and aquatic realms. Recently it been suggested that could also method soil fauna, but so far used only four studies temperate polar regions. We present first study of tropical forests, using a novel analytical pipeline allowing use in-situ recording with minimal disturbance. found significant differences between burnt unburnt forests indications diel cycle soundscapes. These...
A recent Game and Wildlife Conservation Trust (GWCT) report (Hesford & MacLeod 2022) suggested densities of mountain hares (Lepus timidus) may reach 52 - 125/km2 in parts the Peak District, England. These are notably higher than previous current estimates 5 33 hares/km2 (Matthews et al. 2018; Bedson 2022). We review Hesford (2022) who based their methods on those used a hare survey Scotland (Newey 2018). This demonstrated weak, non-significant relationship between encounter rates using...
