“…Likewise, the registration of threatened species such as Furipterus horrens and Natalus macrourus , which are strongly associated with subterraneans habitats, should be enough to apply such regulations. F. horrens , despite being a rare species throughout its distribution area, showed a high frequency of occurrence in the caves studied – indicating that these shelters have occupancy characteristics suitable for the species’ requirements (for example, related to abiotic factors such as light, relative humidity and temperature [Rocha & Bichuette, 2016]); however, previous studies conducted in the Carajás region have shown a decline in its populations, mainly due to its sensitivity to anthropogenic impacts, cave destruction and habitat alterations promoted by mining activities (Bredt, Pinna, & Escalarte‐Tavares, 2018; Bredt, Sbragia, et al, 2018). On the other hand, N. macrourus , although widely distributed throughout Brazil, is infrequent throughout its distribution area and tends to form colonies with hundreds of individuals (as observed in this study); and considering its distribution pattern and the destruction of caves, mainly by mining, its populations are projected to be reduced by around 30 per cent by the year 2028 (Bredt, Pinna, & Escalarte‐Tavares, 2018; Bredt, Sbragia, et al, 2018).…”
