Checklist of Brazilian bats, with comments on original records

Lists of Brazilian bats have been compiled since the late 19th century, with remarkable variation in the criteria for species inclusion and use of nomenclature. To update the list of extant bat species that occur in Brazil, the Brazilian Bat Research Society created the Committee of the List of Brazilian Bats. Here we report the first result of the work of this Committee: a list with nine families, 68 genera, and 178 species with documented occurrence in Brazil, including nomenclatural comments. We also present two additional species lists: one with doubtful records (10 species) and other with erroneous records (six species). Since the beginning of the 21st century, 35 new bat species have been recorded for Brazil, and we anticipate that more species will be uncovered over the next years.

FIG-SEED PREDATION BY 2 SPECIES OF CHIRODERMA: DISCOVERY OF A NEW FEEDING STRATEGY IN BATS

Abstract The feeding ecology of most neotropical bat species is still poorly known, indicating that many complex ecological relationships may be obscured. During a study of bats and their potential role as seed dispersers at the Botanical Garden of Rio de Janeiro, southeastern Brazil, we obtained data on 2 species, Chiroderma doriae and C. villosum, that act as seed predators rather than as seed dispersers. Fecal sample analyses and captive-feeding experiments confirmed this previously undocumented feeding strategy in bats. Both species use a specialized strategy of fig-seed predation, ingesting the rich nutrient content of seeds and discarding most of the coat fragments as compact oral pellets. Evidence from the more abundant C. doriae showed that seeds were consumed in both drier and wetter seasons and by individuals of both sexes, all age classes, and all reproductive stages. Use of seeds, in addition to fruit pulp, probably represents an improvement in the acquisition of nutrients available in figs, showing that the degree of feeding specialization of Chiroderma on this resource may be higher than previous data have shown.

Ecomorphological analysis of the masticatory apparatus in the seed-eating bats, genus Chiroderma (Chiroptera: Phyllostomidae)

Recent data have shown that owing to their seed-predator capacity Chiroderma doriae and Chiroderma villosum trophically depart from all previously studied species within the canopy fruit-bat ensemble. In this paper, the hypothesis that morphological adaptations related to granivory have evolved in these bats is investigated and discussed. A canonical variate analysis was used to search for possible divergent trends between the masticatory apparatus of Chiroderma and other stenodermatines currently recognized in the same ensemble. A total of 142 specimens representative of eight species was included in the analysis. Species of Chiroderma can be discriminated from all other species in the sample based on the increased development of masseter-related variables (height of the anterior zygomatic arch, masseter moment arm, and masseter volume), which, in conjunction with other morphological characteristics (dentition and gape angle) discussed herein, corroborates the evolution of durophagy in this group. A complementary analysis based on a Mantel test revealed that the pattern of morphological differentiation that emerged from the canonical variate analysis does not agree with the one expected based solely on the phylogenetic relationships adopted for the canopy fruit-bats studied here. This result is consistent with the hypothesis that morphological adaptations related to granivory have evolved in Chiroderma.

Quirópteros da Reserva Biológica do Tinguá, estado do Rio de Janeiro, sudeste do Brasil (Mammalia: Chiroptera)

Here we describe the bat community found at the Tingua Biological Reserve, Nova Iguacu County, in the state of Rio de Janeiro, southeastern Brazil. Captures at 14 sites included a total of 31 nights at altitudes from 65 to 1270 m. Bats were captured in nets at ground level in forest trails and clearings, near flowering and fruiting trees, buildings, natural cavities and over streams. The reserve is species rich, with 28 species in 655 captures. Four families were found: Emballonuridae (two species), Phyllostomidae (19), Vespertilionidae (five) and Molossidae (two). Three species are especially important for being considered vulnerable in the Brazilian Threatened Species List: Lonchophylla bokermanni Sazima, Vizotto & Taddei, 1978, Platyrrhinus recifinus (Thomas, 1901) and Myotis ruber (E. Geoffroy, 1806). Forearm length and 13 cranial measurements were studied for each species. The measurements of male and female specimens were treated separately. Taxonomic comments for each species are provided.

Quirópteros do Parque Estadual da Pedra Branca, Rio de Janeiro, Brasil (Mammalia, Chiroptera)

A survey of chiropteran fauna was conducted during the period from March 1994 to May 1998 in Pedra Branca State Park, Rio de Janeiro, Rio de Janeiro State. A total of 681 specimens of 24 species were recorded: Chrotopterus auritus (Peters, 1856); Micronycteris megalotis (Gray, 1842); Micronycteris minuta (Gervais, 1856); Mimmon bennettii (Gray, 1838); Phyllostomus hastatus (Pallas, 1767); Tonatia bidens (Von Spix, 1823); Lonchophylla bokermanni Sazima, Vizotto & Taddei, 1978; Lonchophylla mordax Thomas, 1903; Anoura caudifera (E. Geoffroy, 1818); Glosso-phaga soricina (Pallas, 1766); Carollia perspicillata (Linnaeus, 1758); Artibeus fimbriatus Gray, 1838; Artibeus lituratus (Olfers, 1818); Artibeus obscuras Schinz, 1821; Chiroderma doriae Thomas, 1891; Platyrrhinus lineatus (E. Geoffroy, 1810); Platyrrhinus recifinus (Thomas, 1901); Sturnira lilium (E. Geoffroy, 1810); Vampyressa pusilla (Wagner, 1843); Desmodus rotundus (E. Geoffroy, 1810); Diphylla ecaudata Von Spix, 1823; Eptesicus brasiliensis (DesMarest, 1819); Myotis nigricans (Schinz, 1821) and Molossus molossus (Palas, 1766). One external (forearm length) and 13 cranial meansurements were studied for 23 species. The meansurements of male and female specimens were treated separately. Comments about some taxonomic respects for some species studied are also included.

Morcegos (Chiroptera) da área urbana de Londrina, Paraná, Brasil

Study carried out within the urban perimeter of Londrina, which is located in the North of the state of Parana. The objectives were the identification of urban species of bats and diurnal roosts used by them and the verification of the problems they can cause to the population. The fire brigade, the Autarquia Municipal do Ambiente de Londrina (Municipal Environment Autarchy of Londrina), the Biology Department of the Universidade Estadual de Londrina (State University of Londrina) and local residents helped spot the roosts. The collections were carried out in regular intervals between April 1998 and March 1999. By the end of them, 815 bats of 23 different species had been captured. Among these, 12 were found near or inside human constructions: Noctilio albiventris Desmarest, 1818; Artibeits lituratus (Olfers, 1818); Platyrrhinus lineatus (E. Geoffroy, 1810); Eptesicus brasiliensis Desmarest 1819; Lasiurus bore-alls (Muller 1776); Lasiurus ega (Gervais, 1856); Eumops glaucinus (Wagner, 1843); Molossus rufus (E. Geoffroy, 1805); Molossus molossus (Pallas, 1766); Nyctinomops laticaudatus (E. Geoffroy, 1805); Nyctinomops macrotis (Gray, 1840) e Tadarida brasiliensis (i. Geoffroy, 1824). Roost sites comprised expansion joints, roofs, attics and parks, among others. It can be concluded that bats are treated as undesirable animals by the population due to the lack of knowledge about the subject.

Deslocamento de Artibeus lituratus (Olfers, 1818) (Mammalia, Chiroptera) entre ilha e continente no Estado do Rio de Janeiro, Brasil

One individual of Artibeus lituratus, marked with a colored and numbered plastic color necklace was recaptured on July 18 th , 2007 at the Parque Natural Municipal da Serra do Mendanha, Rio de Janeiro, Brazil, 96 days after being captured and marked at Itacuruca Island, located on southern Rio de Janeiro State. The linear distance between the plots of marking and recapture suggests a minimum movement of 35 km, being 500 m oversea.

New Genus and Species of Nectar-Feeding Bat from the Atlantic Forest of Southeastern Brazil (Chiroptera: Phyllostomidae: Glossophaginae)

ABSTRACT The lowland Atlantic Forest of southeastern Brazil is well known for its biological diversity and numerous endemic taxa. Among bats collected recently at the Reserva Natural Vale and previously in the Floresta Nacional de Goytacazes, in the state of Espírito Santo, are specimens easily recognized as nectar-feeding glossophagines, but that exhibit a suite of morphological traits that preclude assignment to any of the 10 genera currently recognized in the subfamily Glossophaginae. Here we describe a new genus and species based on this material. This new taxon, named Dryadonycteris capixaba, is diagnosed based on both external and craniodental features, including traits not seen in other nectar-feeding phyllostomids, such as similar-sized calcar and foot and inflated maxillary bones. The combination of character states seen in Dryadonycteris suggests that it belongs in the Tribe Choeronycterini, subtribe Choeronycterina, but the mosaic nature of primitive and derived states seen in this taxon precludes easy assessment of its relationships to other choeronycterine genera. Future explicit phylogenetic analyses of morphological data and DNA sequencing studies will be necessary to resolve its phylogenetic position within Choeronycterini.
