Recent studies predict a future decrease in precipitation across the tropics, particularly the Amazon, likely causing significant droughts that have negative consequences for Amazonian freshwater biomes, especially lakes. Furthermore, immediate consequences of global warming for terrestrial fauna associated with tropical lakes are poorly understood as the vast majority of studies come from temperate regions. Here, we assess the seasonal importance of lakes for the conservation of aerial insectivorous bats in the Central Amazon using passive bat recorders. We compared richness, general bat activity and foraging activity between lakes and adjacent forest. Of a total of 21 species/sonotypes recorded in both habitats, all were detected over lakes, and 18 were significantly more active over lakes than in forest. Only two species had significantly higher activity levels in the forest than at the lakes. Species richness and general bat activity over the lakes were higher in the dry than in the rainy season. Foraging activity was also greater over the lakes than within the forest in both seasons. Moreover, both variables were positively correlated with lake size, although the effect on activity was species-specific. Climate change-driven shrinking of lakes may have detrimental consequences for aerial insectivorous bats, especially for the most water-dependent species. Compared to permanent water bodies of other regions, the value of tropical lakes for functionally important taxa, such as bats, has been understudied. Higher bat activity levels over lakes than in forest in both seasons and comprising the whole ensemble of aerial insectivorous bats of the study region, indicate that lakes embedded in Amazonian terra firme forests deserve special attention for future bat conservation.

Bats in urban areas of Brazil: roosts, food resources and parasites in disturbed environments

2016

Urbanization is a widespread intense land use that generally results in biodiversity decline. Among the taxa capable to adapt to urban landscapes, bats are particularly ubiquitous. Brazil has one of the world's largest diversity of bat species and one of the highest urbanization rates of the world. Yet, few studies have synthesized the biology of bats in urban environments, especially in Brazil. To fill this gap, we systematically reviewed the published scientific literature on the bat fauna found in urban areas of Brazil. The knowledge of urban bats is still incipient and heterogeneously spatially distributed, mostly concentrated in the southeastern region of the country. The assembled list of 84 urban species, of which nineteen are new species records for urban areas (including one new family), represents 47% of the bat richness registered in the country. Thirty-one bat species (37%) were captured exclusively inside forest fragments. Moreover, we provide information on the resources used within the urban matrix by summarizing the roosting sites for 38 bat species, as well as 31 plants consumed by at least twelve bat species. Regarding parasitological aspects, we listed eleven zoonotic parasites hosted by 27 bat species and discussed their potential to become a public health threat. Likewise, we considered the different features linked to urbanization, including impacts on immunity, body condition and susceptibility to acquiring parasites, as possible bat conservation issues. Finally, we defined an agenda for bat studies in urban areas of Brazil.

“…Yet, several studies indicate higher capture rates of insectivorous bats, especially molossids and vespertilionids, on water body margins (Myers and Wetzel 1983;Esbérard 2003;Silva 2007;Lourenço et al 2010;Costa et al 2012). Thus, we attribute our successful capture rates of M. lavali (and N. leporinus) to the placing of mist nets in in a V-shape, on the edge of water bodies where these bats forage.…”

Structure and natural history of an assemblage of bats from a xerophytic area in the Caatinga of northeastern Brazil

The Caatinga biome is restricted to Brazil, and its bat fauna is among the least studied in South America, with scarce information on species occurrence, distributions, and structure of assemblages. Moreover, most of the information available on bats from this biome comes from relicts of other ecosystem formations. From 2010 to 2012 we conducted bat surveys in different sites along the Serra da Jitirana, a xerophytic locality in the Caatinga of Piauí state, northeastern Brazil. We recorded 20 species in six families. Representatives of animalivorous guilds predominated in both the number of individuals and species. We speculate that the low numbers of frugivores is a response to the environmental constraints imposed by the drought. Along with an analysis of this assemblage, we also report here new information on roosts, behavior, and feeding items for several species about which little is yet known.
