A complete natural history of the Hebrides – an area of great natural beauty, which draws back thousands of visitors year after year to its wonderful scenery and abundant wildlife.The Hebrides is an area of great natural beauty, which draws back thousands of visitors year after year to its wonderful scenery and abundant wildlife. Yet, until now, there has been no up-to-date, complete natural history for its many followers to refer to. This title fills the gap.In a style at once both readable and informative the Drs. J. M. and I. L. Boyd cover every aspect of the islands. Starting with a clear explanation of the geology, climate and hydrography, they move on to a fascinating description of the many varies habitats, from the sea and inland waters through to woodlands and moor and hill. Part II deals with the characteristics of individual islands and their species, while in part III the islands are discussed in the context of their relation to people – starting with the old naturalists, and ending on a topical note with the current interest in conservation.

The sustainable exploitation of the marine environment depends upon our capacity to develop systems of management with predictable outcomes. Unfortunately, marine ecosystems are highly dynamic and this property could conflict with the objective of sustainable exploitation. This book investigates the theory that the population and behavioural dynamics of predators at the upper end of marine food chains can be used to assist with management. Since these species integrate the dynamics of marine ecosystems across a wide range of spatial and temporal scales, they offer new sources of information that can be formally used in setting management objectives. This book examines the current advances in the understanding of the ecology of marine predators and will investigate how information from these species could be used in management.
