Combining anecdote, scientific theory and practical experience the Sound Approach to birding is a step-by-step guide through tone, pitch, rhythm, reading sonagrams, acoustics, and using sounds to age and sex birds." -- Back cover.
Asked about his forthcoming book, Anthony replied," Having worked myself up from The Observers Book of Birds and pawnshop opera glasses to Swarovski ELs (and abject poverty) it is has been a cathartic experience to survey a life directed by birdwatching. Looking back and writing about what happened has given me a chance to don rose-coloured binoculars and make sure that, with the passage of time and the onset of a failing memory, truth did not get in the way of a good story.

The objective of this manual is to provide guidance to risk assessors on the use of quantitative toxicokinetic and toxicodynamic data to address interspecies and interindividual differences in dose and concentration-response assessment. Section 1 focuses on the relevance of this guidance in the context of the broader risk assessment paradigm and other initiatives of the International Program on Chemical Safety (IPCS) project on the Harmonization of Approaches to the Assessment of Risk from Exposure to Chemicals. Technical background material is presented in section 2, followed by generic guidance for the development of chemical-specific adjustment factors in section 3 and accompanying summary figures. Illustrative case-studies are included in an Appendix, and a glossary of terms is also provided.--Publisher's description.
This volume reviews the current state of knowledge regarding the effects of low-frequency sound on marine mammals and makes recommendations for research. In addition, the book describes current federal regulations prescribed under the Marine Mammal Protection Act that govern the taking of marine mammals by scientific research activities, and it recommends changes to expedite the regulatory process dealing with scientific research activities.
