Bat frugivory in a remnant of Southeastern Brazilian Atlantic forest

nr 1

Knowledge of bat diets may be important for the conservation of small Atlantic Forest fragments because these animals play an important role in seed dispersal and natural recovery of tropical forests. The ‘Reserva Particular do Patrimônio Natural Feliciano Miguel Abdala’ (RPPN-FMA) is a 886-hectare Atlantic forest fragment consisting of a mosaic of distinct successional phases resulting from logging and natural causes, in the state of Minas Gerais, Brazil. We collected 216 fecal samples containing blood, arthropods, pollen-nectar, vegetation (leaflets and fruit peel), fruit pulp (fibers and juice) and seeds, from 18 bat species at the RPPN-FMA. Piperaceae, Solanaceae, Cecropiaceae, and Guttiferae were the most important food resources for frugivorous bats at RPPN-FMA. Piper infrutescences were consumed by Artibeus obscurus, A. fimbriatus, Carollia perspicillata, and Sturnira lilium throughout the year, functioning as key species, as already observed for other tropical rainforest sites.

nr 4

A total of 71 bat flies belonging to families Nycteribiidae and Streblidae, and 37 mites were collected on 12 species of bats (Phyllostomidae and Vespertilionidae) from the Chapada do Abanador (Minas Gerais, Brazil), between July 2009 and April 2010. Two new occurrences of ectoparasites were recorded on Histiotus velatus (bat fly Basilia producta) and on Carollia perspicillata (mite Parichoronyssus bakeri). Five new occurrences were recorded for the state of Minas Gerais, increasing the range for bat flies Anatrichobius passosi, Paraeuctenodes similis, Basilia juquiensis, Basilia producta and for mite Periglischrus vargasi. Moreover, two new species of mites were recorded for Brazil (P. bakeri and Macronyssus aff. leislerianus). With regard to infracommunities, the most frequent association was between Anastrebla modestini and Exastinion clovisi on bat Anoura geoffroyi. This study contributed to characterize the fauna of bat ectoparasites in representative but poorly-sampled environments of the Atlantic Forest, the campos de altitude (high altitude grasslands) and cloud forests of southern Minas Gerais.

Two species and one subspecies are described as new: Trichobius machadoallisoni sp. n., from Pteronotus personatus, is a member of caecus group, and closely related to T. bilobus Wenzel, 1976; however, T. machadoallisoni has the syntergite 1+2 lightly convex and with more than 21 setae. Trichobius anducei sp. n., from Carollia perspicillata, a member of parasiticus complex, differs from all other species in having a strip of long lateral connexival setae, in the number and position of setae in tergite 7 and epiproct in females, in the shape of gonopods, the number of setae in syntergosternite 7+8 and tergite 9 in males. Trichobius dugesioides phyllostomus subsp. n., from Phyllostomus elongatus differs from T. d. dugesioides Wenzel, 1966 in having more denticles in male gonopods and longer posterior setae in the tergite 7 of females. Trichobius d. dugesioides is redescribed, showing sexual dimorphism in distribution of microtrichia in the presutural area of scutum. Some morphotypes of Trichobius joblingi Wenzel, 1966 are compared with Trichobius persimilis Wenzel, 1976, reducing geographical distribution of the latter to the North of Orinoco river.
