“…The absence of noctilionids and Macrophyllum macrophyllum (Phyllostominae) in our mistnet data may be correlated with the almost complete absence of large rivers and other large water bodies in our study area. Noctilio leporinus is well known for its fish-eating habits and N. albiventris mainly for its insect-eating habits (e.g., Hooper & Brown, 1968;Hood & Pitocchelli, 1983). Both species of Noctilio forage predominantly over water surfaces (e.g., Hood & Jones, 1984;Schnitzler et al, 1994;Kalko et al, 1998).…”

In our study of bat diversity in the Amazon Basin, we captured bats in undisturbed continuous forest and in forest fragments at the Biological Dynamics of Forest Fragments Project (BDFFP) near Manaus, Brazil, from January 1996 until July 1999. We recorded 72 species of bats in a sample of more than 7700 individuals caught during 29,900 mistnet hours in terra-firme forest. Species accumulation curves and mathematical estimates of species numbers based on the number of species captured with standardized methodology suggest that we sampled about 95% of the entire expected bat fauna of the area, including aerial insectivorous bats. Our results are similar to those of other mistnetting inventories of Amazonian bat assemblages in terms of species composition and number of species per bat family. Some species considered widespread in Central Amazonia and expected at our study site were not recorded. We interpret their absence as effects of sampling bias and of local ecological conditions. We know from acoustic monitoring (i.e., identification of bats by their echolocation calls) that our mistnet data are incomplete for aerial insectivorous species. We conclude that the development of comprehensive inventories of key vertebrate taxa such as bats derived from a combination of several standardized sampling procedures is essential to develop meaningful, conservation-oriented plans for land-use and management of protected areas.

“…Outros fatores que também poderiam influenciar na partilha de alimento são a estratificação vertical e o padrão de atividade das espécies (McNab, 1971). Estudando populações simpátricas de N. albiventris e Noctilio leporinus, Hooper & Brown (1968) sugeriram ainda que, além dos fatores citados, um período reprodutivo distinto também contribuiria para redução da competição interespecífïca.…”

“…Contudo, os resultados aqui obtidos permitem concluir que N. albiventris apresenta de um a dois períodos de atividade e que ambos se sobrepõem aos de R. naso. Um padrão bimodal de atividade tem sido referido não só para N. albiventris (Brown, 1968;Hooper & Brown, 1968;Brown et al, 1983), como para outros morcegos insetí-voros (Anthony & Kunz, 1977;Marques, 1986;Chase et al, 1991) e pode refletir uma maior abundância na disponibilidade de insetos, como sugerido por Marques (1986).…”

“…Em certas partes de sua distribuição, entretanto, essa espécie pode se reproduzir ao longo de todo o ano (Plumpton & Jones, 1992). Segundo Taddei (1980), variação geográfica também ocorre no padrão reprodutivo de N. albiventris, e enquanto na região amazôni-ca a poliestria bimodal foi sugerida por , na América Central essa espécie tem sido referida como monoestra (Anderson & Wimsatt, 1963;Hooper & Brown, 1968). O caráter assincrônico dos partos, característico em R. naso (Bradbury & Vehrencamp, 1976), também foi registrado no presente estudo através da constatação simultânea de uma fêmea grávida e filhotes em diferentes estágios de desenvolvimento.…”

Observations about Rhynchonycteris naso (WIED-NEUWIED, 1820) and Noctilio albiventris DESMAREST, 1818 (MAMMALIA, CHIROPTERA)Observations about Rhynchonycteris naso and Noctilio albiventris were carried out in the Jaíba region, northern Minas Gerais State, Brazil. Colonies of these bats were found in association with watercourses in areas under considerable antropic influence. The night activity of both species began about half an hour after sunset during approximately one hour. A second period of activity was noted in R. naso, and in the majority of N. albiventris. These bats used temporary night roosts, observing formation of clusters in the later. Capture, with mist-nets, of lactating females in April and October suggest that in this area both species present a bimodal poliestric reproductive pattern, with peaks of births at the beginning and the end of wet season (October to March). The occurrence in sympatry of these species must be facilitated by the greater opportunism of N. albiventris in relation to the foraging areas and due to its capacity of exploring aquatic insects.

“…Bats that use the same food resources and the same vertical space can fly at different times (Hooper and Brown 1968). Time can be used by species in different ways, such as variation throughout the year or periods of the night (Marinho-Filho and Sazima 1989, Aguiar and Marinho-Filho 2004, Ortencio Filho et al 2010.…”

Resources partitioning in a fruit bat community of the southern Atlantic Forest, Brazil

Bat species have differences in diet composition, use of vertical space, and nocturnal activity period. We analyzed diet and partitioning of spatial and temporal resources among fruit bats, and the influence of fruit availability on the number of bat captures in the southern boundary of the Atlantic Forest. Artibeus lituratus and A. fimbriatus fed mainly on Ficus, whereas Sturnira lilium fed on Solanaceae, Piperaceae, and Ficus. However, we did not find correlation between number of fruit bat captures with fruit availability. S. lilium was more active at dusk, whereas A. fimbriatus and A. lituratus were more active at dawn. S. lilium flew more in the understory than canopy and A. lituratus and A. fimbriatus did not show differences in the use of vertical space. There was no difference in the use of vertical space among these fruit bats. We showed that differences in one dimension of the niche, such as food, can help to explain differences in another dimension, such as space use. Niche overlap is greater for related species and studies about niche overlap addressing more than one spatial dimension can elucidate the patterns in use of these resources and also the understanding about bat community composition.
