Bats are fascinating mammals about which we still have much to learn. As well as using ultrasonic echolocation calls for orientation and while foraging, they also have a complex array of vocalisations for communication. These are known as social calls and are an essential component of their colonial lifestyle. This book brings together the current state of knowledge of social calls relating to the bat species occurring within Britain and Ireland, with some additional examples from species represented elsewhere in Europe. It includes access to a downloadable library of calls to be used in conjunction with the book. Downloadable call library Social calls are complex and intriguing to listen to; they are after all produced with listeners in mind (other bats). To enjoy and fully appreciate social calls the reader must also have the opportunity to become a listener: each of the presented sonograms in the book is cross-referenced to downloadable ‘time expanded’ .wav sound files which are contained within a much wider library of calls for you to explore. Included in Social Calls of the Bats of Britain and Ireland The authors start with an overview of the species of bats in Britain and Ireland (Chapter 1), and then introduce us to communication within the social world of bats (Chapter 2). Referencing the latest research, the authors explore how these calls can be classified according to their structure, and in many cases the context in which the calls are thought to be emitted (Chapter 3). Chapter 4 addresses aspects of survey methodology to be considered by those studying social calls. This leads on to the analysis of calls (Chapter 5), detailing the specific methods used and parameters commonly measured by researchers. The final, and main chapter (Chapter 6) introduces the 23 species covered in the book giving each a detailed profile including: habitat preferences, typical roosting locations, roost emergence times, mating strategies and maternity behaviour. Each species profile includes what is known about the social calls for that species and this text is supported by colour sonograms (created using Pettersson BatSound V4.1) of most of the calls discussed. Each sonogram is linked to a .wav sound file (Time Expansion x10) within the downloadable library. The sound files allow the reader to hear, as well as see, the calls produced using any bat sound analysis software that supports the .wav format. The authors conclude with a bibliography and an extensive list of references directly cross-referenced throughout the book.

The Competition Commission (CC) has cleared the anticipated acquisition by BATS Global Markets, Inc of Chi-X Europe Limited. Both companies operate Multilateral Trading Facilities which enable market participants (investment banks, brokers and dealers) to trade equities through a single platform as an alternative to trading on exchanges such as the London Stock Exchange.In this final report, the CC confirms its provisional findings published last month and concludes that the acquisition is not likely to result in a substantial lessening of competition in trading services for UK-listed equities. The CC found that customers would have the power to prevent any attempt by the merged company to raise trading fees or worsen service quality, by taking, or threatening to take, their business elsewhere or even potentially sponsoring new entry. Such sponsored entry has occurred in this sector before: large customers have strong incentives to ensure that trading conditions remain competitive.

Over the past 20 years dramatic declines have taken place in UK insect populations. Eventually, such declines must have knock-on effects for other animals, especially high profile groups such as birds and mammals. This authoritative, yet accessible account details the current state of the wildlife in Britain and Ireland and offers an insight into the outlook for the future. Written by a team of the country's leading experts, it appraises the changes that have occurred in a wide range of wildlife species and their habitats and outlines urgent priorities for conservation. It includes chapters on each of the vertebrate and major invertebrate groups, with the insects covered in particular depth. Also considered are the factors that drive environmental change and the contribution at local and government level to national and international wildlife conservation. Essential reading for anyone who is interested in, and concerned about, UK wildlife.
