Do you think identifying bats in Europe or in North America is difficult? Well, try it in the Amazon. The planet’s green lung is home to the most diverse bat communities on the planet with more than 160 species currently described. Local species richness often surpasses 100 and for many, their identification in the field is, to say the least, challenging. This task will now become easier with the publication of the Field Guide to the Bats of the Amazon: a landmark handbook aimed at facilitating species identification in the field.

The book, written and designed by an international bat research team mainly based in the University of Lisbon in collaboration with the National Institute of Amazonian Research (INPA), is a guide for anyone conducting field work on bats in the Amazon or interested in bat biodiversity. It is largely based on previous published keys with modifications derived from both personal observations and years of field experience in the Brazilian Amazon at the Biological Dynamics of Forest Fragments Project (BDFFP), as well as a thorough revision of available bat keys and species descriptions.

The field guide also features the first acoustic key for Amazonian bats, illustrated with the echolocation spectrogram of most species. This represents a major step towards alleviating the daunting task of identifying the numerous species of aerial insectivorous bats that occur in the Amazon based on their echolocation calls. It further constitutes an important tool to improving the knowledge and optimizing surveys of aerial insectivorous Neotropical bats, a group which remains largely understudied.

The field guide provides an essential tool, not only for researchers, but also for bat conservationists, consultancies and anyone interested in Neotropical bats in general, and Amazonian bats in particular.

Acerca de los autores

Adri� L�pez-Baucells started working with the Bat Research Group, Granollers Museum of Natural Sciences (Catalonia), in 2005. Since then he has collaborated on several projects in fields such as habitat selection, biogeography, behaviour, and migration. He finished his BSc in Biology at the University of Barcelona in 2010 with a final project on neotropical bats based on fieldwork undertaken in Colombia. His MSc thesis was carried out in Sydney (Australia) on behavioural ecology and physiology in megachiroptera.

Currently, he is studying as a PhD student under the supervision of Dr. Christoph Meyer, and Prof. Jorge Palmeirim. His PhD project uses autonomous ultrasound recording stations as a means of investigating the long-term impact of forest fragmentation on aerial insectivorous bats.

Ricardo Rocha has a BSc in Biology by the University of Lisbon and MSc in Conservation Science by Imperial College London with thesis dedicated to S�o Tom� endemic birds’ response to agricultural intensification. Following his MSc, he worked on the ecology of seabirds and endemic reptiles of the Selvagens archipelago (Portugal) and then moved to the Metapopulation Research Centre (Finland) to investigate the efficiency of Malagasy protected areas in reducing deforestation.

He has since worked with bird and bat ecology in Madagascar, Kenya and Brazil. His PhD, based at the Universities of Lisbon and Helsinki and supervised by Christoph Meyer, Jorge Palmeirim and Mar Cabeza, addresses the effects tropical forest fragmentation on the spatiotemporal dynamics of phyllostomid bat communities. He has recently moved to the University of Madeira where he lectures biosystematics and zoology.

Paulo Bobrowiec is a bat researcher at the National Institute for Amazonian Research (INPA). He undertook a BSc in Biological Science at the Universidade Federal de Uberl�ndia and both a MSc and PhD at INPA. His main area of expertise is bat ecology and community structure, feeding strategies, and bat pollination and seed dispersal. His MSc was focused on the effect of secondary vegetation on bat communities, while his PhD was devoted to the feeding ecology of D. rotundus.

Enrico Bernard is a bat researcher and Professor of Conservation Biology at Universidade Federal de Pernambuco, Brazil. He carried out his BSc in Biology in the Universidade de S�o Paulo in Ribeir�o Preto. His MSc was conducted in Ecology at INPA (Manaus), where he worked on the vertical stratification of bat communities. His PhD was obtained from York University, Toronto, Canada, and focused on the effects of forest fragmentation on Amazonian bats.

Jorge Palmeirim is Associate Professor at the University of Lisbon and member of its cE3c research center, where he coordinates the Conservation Ecology. He is also a member of the IUCN Species Survival Commission (Chiroptera Specialist Group). He studied Biology at the Universities of Luanda and Lisbon, followed by an MA and PhD in Systematics and Ecology at the University of Kansas. His main research interests are the ecology and conservation biology of bats and birds, and tropical ecology.
