Abstract Assessing the impact of forest management on bat communities requires a reliable method for measuring patterns of habitat use by individual species. A measure of activity can be obtained by monitoring echolocation calls, but identification of species is not always straightforward. We assess the feasibility of using analysis of time-expanded echolocation calls to identify free-flying bats in the Tomakomai Experimental Forest of Hokkaido University, Hokkaido, northern Japan.

Echolocation Calls of the Bats of Trinidad, West Indies: Is Guild Membership Reflected in Echolocation Signal Design?

Overall classification rates were low compared to similar studies conducted in the Palaeotropics, suggesting that this may be due to a combination of ecological plasticity for certain species and a loose relationship between echolocation call shape, fine-grained resource partitioning and resource acquisition in phyllostomids.

Echolocation Call Structure of Fourteen Bat Species in Korea

The results show that acoustic monitoring could be a powerful tool for assessing bat activity and distribution in Korea, at least for FM/QCF and FM/CF/FM species.

Plasticity in echolocation calls of Myotis macrodactylus (Chiroptera: Vespertilionidae): implications for acoustic identification

This work studied the echolocation behaviors of an ecologically poorly known bat species, Myotis macrodactylus, while they were commuting in three types of habitats differing significantly in the amount of background clutter, as well as searching for prey above the water surface in a river.

Characterization of the Echolocation Calls of Bats from Exuma, Bahamas

The echolocation calls of six species of bats on Exuma, a small island in the Bahamas, are studied, focusing on three species whose calls have not been previously described, Erophylla sezekorni, Macrotus waterhousii, and Nyctiellus lepidus.

Echolocation calls of Natalus primus (Chiroptera: Natalidae): Implications for conservation monitoring of this species

Short, high frequency-modulated multiharmonic calls for N. primus are found; these could be used to identify this species in acoustic inventories conducted in Cuba, constituting a noninvasive approach to study this vulnerable species without causing disturbances on its roosts and foraging areas.

Acoustic identification of two morphologically similar bat species, Miniopterus magnater and Miniopterus fuliginosus (Chiroptera, Miniopteridae)

It is concluded that echolocation calls are valuable characters for the identification of morphologically similar bat species for field identification in China.

Identification of sympatric bat species by the echolocation calls

These parameters of echolocation calls play an important role in identifying bat species and can be used to test the accuracy of general predictions based on bats’ morphology in the same forest and can provide essential information for assessing patterns of bat habitat use.

Dietary composition and echolocation call design of three sympatric insectivorous bat species from China

The results suggest that in the study area the dramatic differences in the dietary composition of these three bat species are mainly based upon Differences in their foraging behaviors, including differences in their echolocation signal structure.

Acoustic Detection of an Unknown Bat Species in Okinawa

Abstract. Pipistrelles of the genus Hypsugo are among the rarest bats in Japan, known from a handful of records. In June 2018, a sequence of echolocation calls apparently by a bat of this genus was

Recent Surveys of Bats (Mammalia: Chiroptera) from China. I. Rhinolophidae and Hipposideridae

Two rhinolophids (Rhinolophus marshalli and R. stheno) and one hipposiderid (Hipposideros cineraceus) represent new species records for China, and some notes on ecology and conservation status are presented.



Identification of British bat species by multivariate analysis of echolocation call parameters

A method for the identification of bat species from time-expanded broad-band recordings of their echolocation calls is presented and may be used for the assessment of habitat use by bats.

Identification of twenty‐two bat species (Mammalia: Chiroptera) from Italy by analysis of time‐expanded recordings of echolocation calls

Spectral and temporal features of echolocation calls emitted by 22 bat species from Italy (three rhinolophids, 18 vespertilionids and the molossid Tadarida teniotis) are described and discriminated functions may be applied to bat habitat surveys in southern Italy since they cover most of the species occurring in the area.

Use of foraging habitats by bats in a Mediterranean area determined by acoustic surveys: conservation implications

We determined habitat use by foraging bats by broad-band acoustic surveys in 10 habitat types from a Mediterranean area (southern Italy). We applied discriminant functions to identify time-expanded

Variation in the echolocation calls of the hoary bat (Lasiurus cinereus) : influence of body size, habitat structure, and geographic location

This work studied the variation in echolocation call design of the hoary bat by analyzing calls from free-flying bats at one site in Manitoba and at four sites in the Hawaiian islands, finding that individuals from the larger subspecies used lower frequency calls than did smaller individuals in Hawaii.

Acoustic identification of insectivorous bats (order Chiroptera) of Yucatan, Mexico

The aim is to provide a catalogue of bat sounds that can be used for acoustic inventories of insectivorous bats using the Pettersson heterodyne and time-expansion bat detectors, suitable for the low-intensity echolocators (mainly the phyllostomids), which are difficult to monitor acoustically.

Echolocation by Insect-Eating Bats

This article describes the echolocation behavior of insect-eating bats and shows how differing circumstances such as habitat type, foraging mode, and diet favor different signal types, and outlines the perceptual tasks that must be performed by foraging bats.

Flexible bat echolocation: the influence of individual, habitat and conspecifics on sonar signal design

The results allow to discuss the problems of echo recognition and jamming avoidance in vespertilionid bats and the role of morphometric differences as the source of individually distinct vocalizations is discussed.

Echolocation call structure and intensity in five species of insectivorous bats.

It is argued that the low-intensity calls of P. auritus allow it to approach tympanate moths more closely before triggering their escape response, and to calculate the energy flux density of the call.

Identification of New Zealand bats (Chalinolobus tuberculatus and Mystacina tuberculata) in flight from analysis of echolocation calls by artificial neural networks

This study represents the first use of neural networks for the identification of bats from their echolocation calls and is the first study to use power spectra of time-expanded and heterodyned calls for identification of chiropteran species.
