Sound level measurements from audio recordings provide objective distance estimates for distance sampling wildlife populations

A Unifying Model for Capture–Recapture and Distance Sampling Surveys of Wildlife Populations

A fundamental problem in wildlife ecology and management is estimation of population size or density. The two dominant methods in this area are capture-recapture (CR) and distance sampling (DS), each with its own largely separate literature. We develop a class of models that synthesizes them. It accommodates a spectrum of models ranging from nonspatial CR models (with no information on animal l...

Audio Information Extraction from Arbitrary Sound Recordings

Numerous archives of entertainment soundtracks and other recordings such as environmental noise samples have imposed a big data challenge in audio related industries. This necessitates the use of machine audition and retrieval tools to extract semantic information for various applications. Speech recognition, environmental noise classification and music information retrieval tools haven been de...

Distance Sampling

Sampling of Bobwhite Populations Estimating Sample Sizes for Distance Sampling of Autumn Northern Bobwhite Calling Coveys

Point transect sampling of calling coveys has been advocated for estimating autumn abundance of northern bobwhite (Colinus virginianus; hereafter bobwhite). We conducted power analysis, over a range of expected bobwhite calling covey densities to determine levels of sampling required to obtain density estimates for calling coveys over a wide range of precision. We used distance/detection inform...

Social Distance in COVID-19 Pandemic and Older Adults Populations

    World Health Organization (WHO) data show higher vulnerable rates of COVID-19 among older adults especially in those with underlying diseases. WHO recommended particularly limitations of social communications for older adults so that control virus transmission among these vulnerable populations. Recommended restrictions included social distancing and stay at home (1). Social distancing is a...
