“…As the recording of calls became more accessible (Adams et al 2012), echolocation techniques are now being used for multiple purposes, from simply detecting the presence of bats (Estrada et al 2004;Ford et al 2006) to more elaborated approaches for studying bat foraging behavior (Britton and Jones 1999;Greif and Siemers 2010), niche differentiation (Sattler et al 2007;Jacobs and Barclay 2009) or species identification (Russo and Jones 2002;Barataud et al 2013;Horta et al 2015). Specifically for species identification, several cryptic species of bats have been discovered based on their echolocation calls alone, or in combination with morphology and genetics (Jones and Parijs 1993;von Helversen et al 2001;Jacobs et al 2006;Ramasindrazana et al 2011).…”

Seventeen species of emballonurid bats are known in Brazil, but their distribution is often determined by patchy records. However, due to almost species-specific calls, echolocation can help to refine the distribution of emballonurids. Here we use acoustic samplings to assess and complement the list of emballonurids of Reserva Biológica Saltinho, an important Atlantic Forest remnant in Pernambuco state, Northeastern Brazil. We positively matched calls of Saccopteryx bilineata (Temminck, 1838) that was foraging along forest edges. However, a series of calls significantly different from those emitted by S. bilineata indicate the presence of a second Saccopteryx sonotype in the area. The lower frequencies in this sonotype presumably came from a larger species, indicating the possible existence of an undescribed cryptic species of Saccopteryx. We also detected Centronycteris maximiliani (Fischer, 1829), recorded 35 years after its first record in Pernambuco, and an undetermined species of Peropteryx Peters, 1867. Our data proved that echolocation is a very useful technique for inventorying poorly known and hard-to-capture emballonurid species, with the potential to reveal the cryptic richness.

“…These calls identify this free-tailed bat with regard to the Egyptian free-tailed bat, Nyctinomus aegyptiacus, reported once in Tunisia [23], which emits calls of higher frequencies (FMAXE: 19.6 ± 1.6 kHz in Morocco [39]). The call frequencies of E. isabellinus were still higher, fell within the range of individuals recorded in Morocco [34], and were only slightly higher than individuals recorded both in Algeria and Spain [37,40].…”

Increasing aridity usually results in decreasing bat abundance and species richness, and the Saharan desert is an example of such impoverishment. Moreover, the harsh climatic and field conditions in this area restrict the feasibility of surveys. Therefore, the bat fauna of the Tunisian Sahara was unstudied until an expedition was conducted in May 2021. A total of seven species were recorded using passive bat detectors set mainly at water bodies, which concentrate bat activity. Echolocation calls of these species did not depart from published records for the Mediterranean area. Our data failed to identify the two ecomorphotypes of Pipistrellus kuhlii but confirmed the adaptability of this species to local conditions. For the first time in Tunisia, we recorded echolocation calls of Taphozous nudiventris, a species that has been rarely reported in North Africa. The highest species richness was identified at the largest wetlands of Oued Daghsen (Oued Dkouk Nature Reserve) and at Bordj el Khadra (only six and four species, respectively). Most Mediterranean species were recorded in the northern locality, while desert species were more active in the most southern one. The importance of water bodies for bats was confirmed once more. No sign of competition among species was detected, as the Mediterranean and desert-dwelling bat species were active at the same time. Additional surveys should be planned in order to enlarge the list of seven species recorded in only one week.
