The bat fauna (Mammalia: Chiroptera) of Carlos Botelho State Park, Atlantic Forest of Southeastern Brazil, including new distribution records for the state of São Paulo

Abstract

Carlos Botelho State Park (PECB) is a large remnant of Atlantic Forest in Southeastern Brazil, with more than 37,000 ha. As its bat fauna is still unknown, we performed the first bat survey on PECB, to provide data on the distribution, natural history and taxonomy of the species. Fieldwork was conducted monthly, from October 2016 to September 2017. Captures were made using ground-level mist-nets (39600 m2.h), canopy mist-nets (2017.5 m2.h) and searches for roosts (42 hours).We captured 412 bats from 34 species of Phyllostomidae, Molossidae and Vespertilionidae. A total of 11 species were captured only in ground-level mist-nets, five in canopy mist-nets, and seven in roosts. Dermanura cinerea Gervais, 1856, Eptesicus taddeii Miranda, Bernardi & Passos, 2006, Glyphonycteris sylvestris Thomas, 1896 and Lampronycteris brachyotis (Dobson, 1879) are rare on surveys conducted in the Atlantic Forest of São Paulo and were captured in canopy mist-nets. Micronycteris schmidtorum Sanborn, 1935 and Molossus currentium Thomas, 1901 constitute the first record for the state of São Paulo, and were captured in canopy mist-nets and roosts, respectively. The species richness registered for PECB surpasses other surveys conducted in Atlantic Forest localities that use only ground-level mist-nets. Our results reinforce the importance of employing mixed capture methods, such as elevated mist-nets and searches for roosts.

New records of Lophostoma brasiliense Peters, 1867 (Chiroptera, Phyllostomidae) from São Paulo and Mato Grosso do Sul, Brazil

“…With the new record, there are now 81 species of bats confirmed to occur in the state of São Paulo (Garbino 2016;Cláudio et al 2020). The western region of São Paulo is one of the least known areas of the state in terms of mammal diversity, and new findings are still being made in the region (Garbino 2016;Prist et al 2020).…”

Occurrence of Sturnira tildae De La Torre, 1959 (Chiroptera: Phyllostomidae) in the state of Maranhão, Brazil

“…As for distribution, S. tildae is considered a common species within its geographic distribution (Wilson 1996;Miretzki et al, 2002), with a distinct preference for more humid forest environments (Trajano, 1984;Marques, 1985;Brosset et al, 1996;Simmons & Voss, 1998;Miretzki et al, 2002;Novaes & Laurindo, 2014), such as the locality surveyed during the present study. Even so, S. tildae has been captured relatively infrequently in most bat field studies, in all different biomes (Oliveira, 2000;Marques-Aguiar et al, 2002;Miretzki et al, 2002;Carvalho et al, 2013;Luz et al, 2013;Menezes et al, 2015;Maas et al, 2018;Cláudio et al, 2020;Martins et al, 2020).…”

Revisiting Molossus (Mammalia: Chiroptera: Molossidae) diversity: Exploring southern limits and revealing a novel species in Argentina

“…nov.). Measurements were taken using a digital caliper, supplemented in some cases by data obtained from the existing literature (Thomas 1901;Cláudio et al 2020;Montani et al 2021;2023;Pavé et al 2023;Olímpio et al 2024). We included five external [total length (ToL), tail length (TL), hindfoot length (HFL), ear length (EL), forearm length (FA)] and 14 cranial measurements [greatest length of skull with incisors (GLS w.i), greatest length of skull excluding incisors (GLS wo.i), condylobasal length (CBL), postorbital constriction (PC), braincase breadth (BB), zygomatic breadth (ZB), mastoideal breadth (MB), maxillary toothrow length (LMxT), palatal length (PL), width across canines (C-C), width across second molars (M2-M2), mandible length (LM), mandibular toothrow length (LMdT), height of the sagittal crest (SAR)] for each species.…”
