The jaguars presented furuncular myiasis caused by the human botfly Dermatobia hominis (L.) on the rear thighs and tail. This is the first record of infestation of D. hominis in P. onca in the Amazon region.

Essa associacao comumente leva a especializacao ecologica que, em plantas, envolve fatores abioticos como nutrientes e agua. Nesse trabalho nos investigamos como os gradientes hidrico (Altura acima da drenagem mais proxima - HAND) e fertilidade (teor de fosforo e soma de bases K +, Ca2+e Mg2+) restringem a distribuicao de especies de seis formas de vida de comunidades vegetais em uma floresta tropical na Amazonia Central.

One of these, Nerodia fasciata (Linnaeus, 1766), is a species endemic to the Coastal Plain of South and North Carolinas and throughout the state of Florida (Gibbons and Dorcas, 2004, 2005). The species is considered a habitat generalist, living in bayous, lakes, and ponds, where individuals can stay submerged up to 24 min (Palmer, 1995; Werler and Dixon, 2000; Gibbons and Dorcas, 2004). In these environments, the species feeds mainly on fishes and anurans (Gibbons and Dorcas, 2005). The bittern Botaurus lentiginosos (Racket, 1813) also lives in these humid habitats. The species is migratory and in the summer ranges from central Nevada and Colorado, east to southern Wisconsin, eastern Pennsylvania, New England, and the southern half of Canada (breeding season) (Gibbs and Melvin, 1992; Alderfer, 2006; Huschle et al., 2013). Conversely, in the wintering season, it ranges from the southern portion of the Atlantic coastal Un...

Although there is no consensus on the evolution of nocturnality in bats, many authors mention risk of predation, overheating, competition and mobbing by non-competitor species as arguments to justify nocturnal instead of daytime flight in bats. Herein we describe the first records of three genera of phyllostomid bats flying, foraging and drinking water during daytime in the Brazilian Amazon. All taxa were recorded drinking water, and some Phyllostomus sp. individuals were recorded foraging on termites, alongside birds. Risk of dehydration and overheating in roosts, as well as low competition in daytime, may explain the emergence of phyllostomid bats before sunset.

The diet and foraging patterns of this species are poorly known. We analyzed the composition of the diet of a population of T. bidens and how the temperature influences the consumption of vertebrates and invertebrates. To describe diet composition, we conducted weekly collections of food scrap from two monospecific night-perches. Data of temperature for the study period were taken from the meteorological station installed 300 m from the collection perches. The influence of temperature was evaluated using generalized linear models (GLMs) with negative binomial distribution. Tonatia bidens consumed 28 taxons (204 records), being at least 17 Artropods and 11 Passeriformes birds. Temperature explained a greater proportion of vertebrate abundance (R2 = 0.23) than invertebrate (R2 = 0.16) or to both pooled (R2 = 0.11). The relation with t...

This species has few confirmed records throughout its distribution. Here we report the first record of L. egregius from the northern coast of Paraná state, southern Brazil. We captured a female individual of L. egregius using an ultrathin mist-net installed over a river knee, at Salto Morato Natural Reserve, municipality of Guaraqueçaba. This is the fourteenth locality with confirmed occurrence of L. egregius, being eight of them in Brazil. The knowledge on the bat fauna in Paraná has been increasing in recent decades, mainly due to the new studies in coast areas of this state. In addition to contributing to the knowledge of the bat fauna from Paraná, the new record of L. egregius reinforces the essential role of the Salto Morato Natural Reserve in conserving bats in the southern portion of the Atlantic Forest.

Data on the exploration of these resources help ecologists to understand how interspecific relations shape the community dynamic and structure food webs and energy flux in ecosystems (Werner and Peacor, 2003; Falico et al., 2012; Linares et al., 2016). Knowledge on trophic relations in pairs of exotic invasive and native species is particularly relevant to conservation, because invasive species are considered the second main threat to native biodiversity worldwide after habitat destruction (Vitousek et al., 1996; Salinas, 2006). Exotic invasive species are the most serious threat of the native ecosystems in North America (Peterson et al., 2003). Florida State (southern United States) owns the greatest diversity of exotic invasive anuran species in the World (Krysko et al., 2011). Among them the Cuban Tree-frog Osteopilus septentrionalis (Duméril & Bibron, 1841) (Anura, Hylidae), which had been accidently introduced in the state by a Cuban ...

De maneira didática e com linguagem simplificada, os leitores poderão conhecer as espécies de morcegos que ocorrem ao longo da BR-319, entender do que elas se alimentam, sua importância para o meio ambiente, os serviços ecológicos que desempenham e, o principal, que as ameaças que os morcegos representam para a população local existem mais no inconsciente coletivo do que na própria realidade. Esperamos que gostem do livro e compartilhem as informações contidas nele.

This book takes a clear, educational approach to teach readers about the bat species living along the BR-319 highway. This road runs through the rainforest between the cities of Manaus and Humaitá. Readers will also learn aboutwhat these bats eat, their role in nature, and how they help the environment. We especially want to highlight that bats don’t threaten people nearly as much as some think. We hope you find this book interesting and will share what you learn. Enjoy reading and learning!
