Practical Skills in Biology is an indispensable book for undergraduate students in the life sciences. The book provides useful support at all stages of a degree course and underpins any practical course in biology. It is also a valuable resource for teachers of biology in colleges and secondary schools. Laboratory and field studies are essential components of undergraduate training in biology. Practical work must be fully understood and effectively presented, but many students under-perform because they lack basic laboratory skills. This book, now in its fourth edition, continues to provide students with easy-to-use guidance for laboratory and field studies, but in addition it now covers broader transferable skills. As a result the new edition provides guidance and support over the entire range of a typical undergraduate course in biology.
