Aspects of Littorinid Biology
Members of the family Littorinidae are among the most widely studied gastropod molluscs and the more questions we answer about this group, the more questions are inevitably posed. Littorinid research spans diverse disciplines, from molecular biology, physiology, ecology, systematics and evolutionary biology to elegant anatomical studies. The papers n this volume reflect the current research being carried out on littorinids, and fall into three broad themes: systematics, ecology, and pollution studies. This book is primarily targeted at the research level, while providing useful information for advanced first-degree students conducting research projects.
Clash of Cultures?
The general perception of the west midlands region in the Roman period is that it was a backwater compared to the militarized frontier zone of the north, or the south of Britain where Roman culture took root early – in cities like Colchester, London ,and St Albans – and lingered late at cities like Cirencester and Bath with their rich, late Roman villa culture. The west midlands region captures the transition between these two areas of the ‘military’ north and ‘civilized’ south. Where it differed, and why, are important questions in understanding the regional diversity of Roman Britain. They are addressed by this volume which details the archaeology of the Roman period for each o...
Snails on rocky sea shores
The snails found living on rocky sea shores are among the most rewarding invertebrate animals to study. Species such as dog-whelks, topshells and winkles are easy to find, capture, identify, measure and mark. This book provides a key to common species, background ecology, an overview of rocky shore habitats and the techniques required for anyone to study this fascinating and accessible fauna.
Advances in Littorinid Biology
Members of the gastropod family Littorinidae are common throughout the world. They form a very abundant component of many intertidal and shallow subtidal ecosystems and, by their grazing, often play a central role in shaping these communities. They also display a wide range of life history strategies and many are polymorphic, making them attractive model organisms for ecologists, evolutionary biologists and physiologists alike. Areas of particular interest include ecological interactions with other animals and with algae, the effects of pollutants and the use of littorinids as sentinel species for monitoring pollution, the effects of parasites on growth and ecology, taxonomy, and the study of genotypic/phenotypic responses to environmental factors. There is still much to be done, and the littorinids are proving to be an ideal group on which to work. Audience: Primarily targeted at the research level. Will also provide useful information for advanced first-degree students conducting research projects.
British Seashells
Using original Victorian prints, by collectable artist George Sowerby, marine biologist and author Paul Chambers has produced the first comprehensive guide to shells for over a century. The original prints are intricately detailed (much better than photographs which lack the exact detail of these drawings) and are a selling point in themselves but will be complemented by informative but accessible text, including families and to show what's edible, dangerous or belongs to mollusc families and in what part of the country they can be discovered. A delightful study by the leading expert and a must for anyone interested in learning more about shells - or who just enjoys beachcombing with the family.

The Natural History of Inbreeding and Outbreeding
Inbreeding, the mating of close kin, and outbreeding, the mating of distant relatives or unrelated organisms, have long been important subjects to evolutionary biologists. Inbreeding reduces genetic diversity in a population, increasing the likelihood that genetic defects will become widespread and deprive a population of the diversity it may need to cope with its environment. Most plants and animals have evolved behavioral and morphological mechanisms to avoid inbreeding. However, today many endangered species exist only in small, very isolated populations where inbreeding is unavoidable, so it has become a concern for conservationists. In this volume, twenty-six experts in evolution, behav...
