“…Found in tropical and subtropical regions, 54 species of bats belonging to the family Emballonuridae are currently known (Simmons et al 2005;Goodman et al 2006Goodman et al , 2008Lim et al 2010). Among those, 17 are recognized in Brazil (Nogueira et al 2014).…”

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.

“…Coleura afra is the smallest species of the family in Africa and is distinguished from all other Emballonuridae by the absence of a gular sack and radio carpal pouches, a body weight of 10-12 g, its deep brown fur which is paler at the base than at the tip, its smaller size (Fore Arm < 55 mm) and the three pairs of lower incisors [1,9,10,28,33,34,35]. The bat generates sound through tongue clicks or vocalization that occurs as paired clicks and stretches into the ultrasonic range (20 kHz -100 kHz); essential in communication and navigation purposes [12,17,25].…”

“…The Ankarana bat species assemblage is also notable in including one of only two known occurrences in Madagascar of colonies of Coleura afra (Peters 1852) (Emballonuridae), which occurs in Africa as well (Goodman et al. , 2005; Goodman, Cardiff & Ratrimomanarivo, 2008a). Previous work at Ankarana suggested that hunting, which is illegal in the Reserve but legal most of the year outside of it, and roost site disturbance by tourists and artisanal miners were potential concerns for at least some of these species (Wilson et al.…”

Surveys and monitoring of 37 caves in and around the Ankarana Special Reserve, northern Madagascar, yielded evidence of hunting of bats and potential disturbance of bats by miners and tourists, and colony counts for several bat species of potential conservation concern. Colony size decreased by 95% and 14% for a colony of Hipposideros commersoni and a colony of Eidolon dupreanum, respectively, when recent evidence of hunting occurred at those colonies and those declines are probably attributable to hunting. Evidence of hunting occurred commonly at the roosts of those species and most commonly at the roosts of Rousettus madagascariensis. Hunting of pteropodids was associated with high vulnerability of roosts to hunters, little forest buffer between the cave and open savannah and the absence of tombs in the cave. Roost sites of the hunted species persisted for at least several years and this regularity may facilitate hunting. This work supports the ranking of E. dupreanum, R. madagascariensis and H. commersoni as species of conservation concern. Managers should consider the impact of tourist visits on bats and of increasing access to caves for tourism. Conservation efforts for the hunted species should also seek to protect vulnerable and unprotected cave roosts.
