Why are there so many species in tropical rainforests? How can so many species coexist at one site? Is there interspecific competition?Neotropical leaf-nosed bats (Phyllostomidae) form assemblages with higher species richness than any other mammalian family. This book gives an insight into diversity, assemblage structure, interspecific competition and resource partitioning of both food and foraging space in three leaf-nosed bat assemblages with different species richness. First, a validation of species richness estimation methods is presented revealing the most species rich bat assemblage reported in literature. Furthermore, evidence is produced showing that large scale floral patternsmay influence species composition of phyllostomid bat assemblages. Resource partitioning among species appears to occur evenly throughout the entire assemblage, thus interspecific competition is not restricted to groups such as dietary ensembles (guilds). Vertical stratification of species is studied using stable carbon isotopes and the results indicate that species share foraging space evenly along the vertical axis of the forest. Dietary analyses based on fecal samples andnitrogen isotopes indicate that leaf-nosed bats are opportunistic omnivores, able to adjust their diet to local and seasonal differences in food availability. This dietary flexibility is likely to be a key factor in maintaining the extraordinarily high local diversity in phyllostomid bat assemblages.

In recent years researchers have discovered that bats play key roles in many ecosystems as insect predators, seed dispersers, and pollinators. Bats also display astonishing ecological and evolutionary diversity and serve as important models for studies of a wide variety of topics, including food webs, biogeography, and emerging diseases. In Bat Ecology, world-renowned bat scholars present an up-to-date, comprehensive, and authoritative review of this ongoing research. The first part of the book covers the life history and behavioral ecology of bats, from migration to sperm competition and natural selection. The next section focuses on functional ecology, including ecomorphology, feeding, and physiology. In the third section, contributors explore macroecological issues such as the evolution of ecological diversity, range size, and infectious diseases (including rabies) in bats. A final chapter discusses conservation challenges facing these fascinating flying mammals. Bat Ecology is the most comprehensive state-of-the-field collection for scientists and researchers.

This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.

Bats are highly gregarious mammals that have been extensively studied for their ability to echolocate (i.e., gain information from the echoes of ultrasonic calls) to navigate and find food. Perhaps less well studied are social vocalizations, which bats use to communicate with conspecifics. Some bat species have been shown to possess rich vocal repertoires, supporting intricate social interactions. While the roost is likely where the majority of a bat's social interactions occur, on account of higher densities, there are also behavioral contexts that occur predominantly, if not solely in flight, that are associated with social calls. Bats exhibit an extensive range in social group size, social group organization, and mating systems, making them interesting for comparative, phylogenetically controlled analyses. Group size is often correlated with vocal complexity, as more complex vocalizations can encode more information about individual identity. Vocal learning has been observed in some species of bats. The full vocal repertoires of relatively few bat species have been studied thus far, as they are nocturnal, volant animals that produce predominately ultrasonic vocalizations. With more data available, bats would be a very useful taxon for studying the evolution of social communication, as they exhibit not only a high diversity of social group size and complexity but also sophisticated vocalizations. Social vocalizations can be structurally diverse and are highly important for bat sociality. Calls often vary notably between species. Research in this field has barely scratched the surface, and there is still much to learn about social communication in bats.

Insect trapping is a basic field research tool for many biologists, whether they are studying insect pests, disease vectors or insect ecology for its own sake. Any field entomologist contemplating a new insect trapping program or looking to improve or develop an existing scheme will benefit from this broad review of flying insect traps, in which the author draws on a wide variety of methods used by different research projects from all over the world. Over the years a great many traps have been developed and endlessly modified to suit particular species, habitats, and research requirements. In virtually every case the design of the trap interacts with the specific behavior of the insects involved to bias trap efficiency. In addition, the limited dialogue between workers in different subject disciplines and habitats has caused a shortage of new information available to field entomologists as a whole. Describes and evaluates the main methods of trapping flying insects Brings together results from agricultural/forest/pest studies and those from medical entomology

The average kilometer of tropical rainforest is teeming with life; it contains thousands of species of plants and animals. As The Ornaments of Life reveals, many of the most colorful and eye-catching rainforest inhabitants—toucans, monkeys, leaf-nosed bats, and hummingbirds to name a few—are an important component of the infrastructure that supports life in the forest. These fruit-and-nectar eating birds and mammals pollinate the flowers and disperse the seeds of hundreds of tropical plants, and unlike temperate communities, much of this greenery relies exclusively on animals for reproduction. Synthesizing recent research by ecologists and evolutionary biologists, Theodore H. Fleming and W. John Kress demonstrate the tremendous functional and evolutionary importance of these tropical pollinators and frugivores. They shed light on how these mutually symbiotic relationships evolved and lay out the current conservation status of these essential species. In order to illustrate the striking beauty of these “ornaments” of the rainforest, the authors have included a series of breathtaking color plates and full-color graphs and diagrams.

With more than two hundred species distributed from California through Texas and across most of mainland Mexico, Central and South America, and islands in the Caribbean Sea, the Phyllostomidae bat family (American leaf-nosed bats) is one of the world’s most diverse mammalian families. From an insectivorous ancestor, species living today, over about 30 million years, have evolved a hyper-diverse range of diets, from blood or small vertebrates, to consuming nectar, pollen, and fruit. Phyllostomid plant-visiting species are responsible for pollinating more than five hundred species of neotropical shrubs, trees, vines, and epiphytes—many of which are economically and ecologically important—and they also disperse the seeds of at least another five hundred plant species. Fruit-eating and seed-dispersing members of this family thus play a crucial role in the regeneration of neotropical forests, and the fruit eaters are among the most abundant mammals in these habitats. Coauthored by leading experts in the field and synthesizing the latest advances in molecular biology and ecological methods, Phyllostomid Bats is the first overview in more than forty years of the evolution of the many morphological, behavioral, physiological, and ecological adaptations in this family. Featuring abundant illustrations as well as details on the current conservation status of phyllostomid species, it is both a comprehensive reference for these ecologically vital creatures and a fascinating exploration of the evolutionary process of adaptive radiation.
