“…The lack of bat pollination and seed dispersal may affect not only plant populations, but also people that count on their fruit production, quality and availability . Bats are also important in the control of agricultural pests, a service studied in the northern hemisphere (Lee & McCracken 2005), but ignored in Brazil (Aguiar & Antonini 2008). The identification and conservation of the bat species involved with these environmental services are important in a country that has agro-business as a main source of income, and that seeks a more sustainable model for its agro-economy.…”

1. Brazil is the second most bat species-rich country in the world, but the available information on the occurrence and distribution of bat species in Brazil is still heterogeneous and fragmented. 2. We review the occurrence and distribution of bat species in Brazil, analyse the spatial performance of inventories conducted to date and identify knowledge gaps. We also identify the main factors contributing to the recent increase in the knowledge of the Brazilian bat fauna, and make suggestions for maintaining this momentum into the near future. 3. We plotted record coordinates on a map, grouped them in 0.5 degrees of latitude ¥ 0.5 degrees of longitude grid cells, and analysed records for each of the five terrestrial biomes in Brazil, and for the 1439 priority polygons for the conservation of Brazilian biodiversity. 4. We identified 5502 formal bat records in Brazil, indicating that less than 10% of the country is minimally surveyed, and that for nearly 60% of Brazil there is not a single record of bat species. Record coverage varies from 79% in the Atlantic Forest to 24% in Amazonia, but none of the Brazilian biomes is well surveyed for bats. Bat species have been recorded in only 15% of the priority areas for Brazilian biodiversity conservation. 5. If the current rate of recording bats in empty grid cells (10% every 4 years) was maintained, it would take 33 years for all cells to have a single record. If the current rate of recording Ն20 species in a grid cell (0.8% per year) was maintained, it would take 200 years for the bat fauna of Brazil to be minimally surveyed. Alarmingly, most of the data-poor areas are at the expansion frontiers of the agro-business, near the surrounding deforestation fronts. 6. We make recommendations for scientific research on bats in Brazil, to ensure the conservation of this ecologically important taxon.

“…Its biology and natural history have been extensively investigated (Wilson and Findley 1970, Wilson and Findley 1971, Wilson 1971i, LaVal 1973, Wilson and LaVal 1974, Siemers et al 2001). The species has been classified as an aerial insectivorous that forages in forested and open habitats (Findley 1993), feeding on a variety of insects in the orders Coleoptera, Diptera, Ephemeroptera, Homoptera, Hymenoptera, and Lepidoptera, and small spiders as well (Wilson and LaVal 1974, Aguiar and Antonini 2008). …”

BackgroundMyotis occurs from tropical to temperate regions throughout the globe, and it is the largest bat genus with more than 100 species. Most species are insect-eaters, but a few also feed on other invertebrates and fishes; there is no confirmed evidence of a plant item in their diet.New informationDuring fieldwork in the Brazilian Atlantic Forest, small seeds were retrieved from the feces of one adult female of the Black Myotis, Myotis nigricans—one of the most common Neotropical bats. In a germination experiment, 40% of those seeds grew into seedlings. Our findings are the first evidence of fruit consumption for any Myotis species. We reject a possible contamination because the cotton bag was never used before for bats. This study is the first evidence of frugivory in the genus Myotis.

“…Such bats (e.g., Pipistrellus spp. and Myotis nigricans ) feed aerially on flying insects; non-volant prey such as spiders is almost entirely missing in their diets [75]–[77]. In contrast, there are some bats that feed heavily on web-building spiders (e.g., Phoniscus papuensis , Myotis emarginatus , Myotis nattereri , Myotis bechsteinii , Myotis keenii , Myotis lucifugus , Myotis aurascens ; see [78]–[85]).…”

In this paper more than 50 incidences of bats being captured by spiders are reviewed. Bat-catching spiders have been reported from virtually every continent with the exception of Antarctica (∼90% of the incidences occurring in the warmer areas of the globe between latitude 30° N and 30° S). Most reports refer to the Neotropics (42% of observed incidences), Asia (28.8%), and Australia-Papua New Guinea (13.5%). Bat-catching spiders belong to the mygalomorph family Theraphosidae and the araneomorph families Nephilidae, Araneidae, and Sparassidae. In addition to this, an attack attempt by a large araneomorph hunting spider of the family Pisauridae on an immature bat was witnessed. Eighty-eight percent of the reported incidences of bat catches were attributable to web-building spiders and 12% to hunting spiders. Large tropical orb-weavers of the genera Nephila and Eriophora in particular have been observed catching bats in their huge, strong orb-webs (of up to 1.5 m diameter). The majority of identifiable captured bats were small aerial insectivorous bats, belonging to the families Vespertilionidae (64%) and Emballonuridae (22%) and usually being among the most common bat species in their respective geographic area. While in some instances bats entangled in spider webs may have died of exhaustion, starvation, dehydration, and/or hyperthermia (i.e., non-predation death), there were numerous other instances where spiders were seen actively attacking, killing, and eating the captured bats (i.e., predation). This evidence suggests that spider predation on flying vertebrates is more widespread than previously assumed.
