Woodlice are one of the few land-living groups of the class Crustacea. In order to live in such a harsh environment, they have evolved many structural and behavioural mechanisms to conserve water. This book covers not only the morphology and physiology of woodlice but also the behaviour, genetics and population ecology. The parasites and predators, and distribution and range of the British species are described. A checklist of British species of woodlice accompanies an illustrated identification key. Practical ideas of study techniques are supported by many suggestions for further investigation - many of which are accompanied by detailed instructions

The common woodlouse is one of nature’s most recognizable insects, though many people call it a pill bug or rolly-polly. Readers will learn all about this small and gross insect, discovering what it looks like, where it lives, how its special body acts as a defense against predators. Age-appropriate language makes elementary science content accessible to readers, while colorful photographs reinforce the text in an exciting and engaging way.

Readers learn about wood lice, their life cycle, behavior and more.

The book traces the ways in which terrestrial animals have evolved from aquatic ancestors and discusses the means by which they are adapted to life on land. The most important physiological adaptations are those involving salt and water balance, the excretion of nitrogen, reproductive mechanisms and the sense organ and these are given priority. Evidence from fossil history is combined with that from the ecology and physiology of present-day species to assess the probable routes along which various evolutionary lines had moved on to land. Individual chapters are concerned with specific animal groups and emphasis is placed on comparisons of physiological mechanisms between closely related animals before attempting wider generalisations. The book closes with a brief account of the recolonisation of the sea and fresh waters by terrestrial animals.

The Science Web series provides resources that cover National Curriculum Key Stage 3 science and the approaches outlined in the QCA scheme of Work for Science. This enquiry pack includes student and teacher materials back-to-back for easy reference and management, guidance and notes for technicians, materials suitable for individual and group work and suggestions on the use of ICT to support the development of enquiry skills.
