“…For a wide range of sound-producing taxa, acoustic information has been extensively used to make inferences about presence in a given area (e.g. O'Farrell & Gannon, 1999; Kimura et al ., 2009; Bucci, Petryszyn & Krausman, 2010; Clark, Brown & Corkeron, 2010) or relative abundance (e.g. Forrest, 1988; Van Parijs, Hastie & Thompson, 1999; Ichikawa et al ., 2006; Van Parijs & Clark, 2006; Oleson et al ., 2007; Stafford et al ., 2007; Širović et al ., 2009).…”

Estimating animal population density using passive acoustics

Reliable estimation of the size or density of wild animal populations is very important for effective wildlife management, conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting animals from transect lines or some form of capture-recapture on marked or uniquely identifiable individuals. However, many species are difficult to sight, and cannot be easily marked or recaptured. Some of these species produce readily identifiable sounds, providing an opportunity to use passive acoustic data to estimate animal density. In addition, even for species for which other visually based methods are feasible, passive acoustic methods offer the potential for greater detection ranges in some environments (e.g. underwater or in dense forest), and hence potentially better precision. Automated data collection means that surveys can take place at times and in places where it would be too expensive or dangerous to send human observers.Here, we present an overview of animal density estimation using passive acoustic data, a relatively new and fast-developing field. We review the types of data and methodological approaches currently available to researchers and we provide a framework for acoustics-based density estimation, illustrated with examples from real-world case studies. We mention moving sensor platforms (e.g. towed acoustics), but then focus on methods involving sensors at fixed locations, particularly hydrophones to survey marine mammals, as acoustic-based density estimation research to date has been concentrated in this area. Primary among these are methods based on distance sampling and spatially explicit capture-recapture. The methods are also applicable to other aquatic and terrestrial sound-producing taxa.We conclude that, despite being in its infancy, density estimation based on passive acoustic data likely will become an important method for surveying a number of diverse taxa, such as sea mammals, fish, birds, amphibians, and insects, especially in situations where inferences are required over long periods of time. There is considerable work ahead, with several potentially fruitful research areas, including the development of (i) hardware and software for data acquisition, (ii) efficient, calibrated, automated detection and classification systems, and (iii) statistical approaches optimized for this application. Further, survey design will need to be developed, and research is needed on the acoustic behaviour of target species. Fundamental research on vocalization rates and group sizes, and the relation between these and other factors such as season or behaviour state, is critical. Evaluation of the methods under known density scenarios will be important for empirically validating the approaches presented here.

“…Although bats have been documented near or roosting in buildings in the southeastern United States (O'Keefe and LaVoie , Fagan et al ), to our knowledge no research has been conducted to investigate roost selection by building‐roosting bats in the region. Similarly, limited studies have examined roost selection by bats in historical buildings used for tourism in North America (Bucci et al , Bucci et al ), and roost selection by other North American Vespertilionids known to use buildings, including the eastern small‐footed bat ( Myotis leibii ) and Rafinesque's big‐eared bat ( Corynorhinus rafinesquii ). In this context, our study is among the first to examine summer roosting ecology of building‐roosting bats in the southeastern United States, providing region‐specific information necessary for informed management actions.…”

Roost selection by bats in buildings, Great Smoky Mountains National Park

Bats roosting in buildings are a challenge for wildlife managers because of their conservation needs, capacity to transmit disease, and potential to damage structures. An understanding of roost selection by bats in buildings is important for effective management but was lacking in the southeastern United States. During 2015 and 2016, we surveyed 140 buildings in Great Smoky Mountains National Park in eastern Tennessee and western North Carolina, USA for bats, identifying 48 roost sites and detecting 5 species. We compared the microclimate conditions, building features, and habitat patch characteristics of buildings used and unused by bats using an information-theoretic approach. Averaged parameter estimates from logistic regression models developed with survey data indicated bat presence was more likely in old buildings with dark conditions surrounded by low road density. Of all roost buildings surveyed, 65.9% were accessed regularly by tourists and 68.2% were managed as historical structures. We present alternative management strategies that may be implemented to ensure human health and safety and preserve historical sites while protecting bats during the reproductive period.

“…Our study shows clearly that the presence of bats in archeological structures should be studied to implement policies and strategies of management and maintenance that ensure the integrity of the structures, the health and safety of personnel and visitors, and the conservation and welfare of bats (Bucci et al., 2010; Fagan et al., 2017; Howard, 2009). Their ability to fly dozens or more kilometers away from their roosts increases AZ benefits regarding bat ecosystem services associated with seed dispersal, insect pest consumption, and plant pollination (Boyles et al., 2013; Medellín, 2023; Medellín et al., 2017).…”

The role of archeological zones in biological conservation has been highlighted because of their restrictions over land‐use change, size, and maintenance of upstanding vegetation. The Yucatan Peninsula in Mexico has over 2000 archeological zones amidst biological, ecological, and culturally diverse landscapes. However, due to population centers and tourism growth, the peninsula is experiencing high deforestation and habitat fragmentation rates. To explore the role of archeological zones in biological conservation, we focused on bat species because of their high mobility, use of human structures as refugia, and the ecosystem services they provide. Using mist nets and roost surveys, we compared the bat diversity in four highly visited archeological zones during the dry and wet seasons. In a total effort of 34,560 m2 mist net hours, we found 23 species from six families and seven guilds, representing 53% of all bat species known from the Yucatan state, including two endangered species for Mexico: Mimon cozumelae and Micronycteris schmidtorum. We found between 12 and 19 species in each archeological zone, and the communities were similar between the four sites and between seasons. The Phyllostomidae family was dominant across all sites, accounting for 92% of all the captures. We also recorded 12 species across 52 diurnal and nocturnal roosts, suggesting that Mayan archeological structures could offer several advantages to bats despite the high visitation of tourists. Our results emphasize the need to conduct research beyond natural protected areas to complement conservation policies and incentivize the inclusion of archeological zones in Yucatan's bat conservation plans.Abstract in Spanish is available with online material.
