Researching your family history can take a lifetime. It can be very frustrating but also rewarding. Gladys has been exploring her genealogy for many years. She has encountered pitfalls and brick walls, but has produced a comprehensive tree that is the envy of many people. Using the story of her research, she takes us through the process of her investigations and gives us an insight into how we could build our own family tree.

This study, first published in 1942, helped to revolutionize evolutionary biology by offering a new approach to taxonomic principles, and correlating the ideas and findings of modern systematics with those of other life disciplines. This book is one of the foundational documents of the Evolutionary Synthesis. It is the book in which Ernst Mayr pioneered his concept of species based chiefly on such biological factors as interbreeding and reproductive isolation, taking into account ecology, geography and life history. In the introduction to this edition, Mayr reflects on the place of this work in the subsequent history of his field.

Ecology: Principles and Applications is a comprehensive textbook for A-level students and first-year undergraduates taking courses in biology, geography and Earth sciences, who require an introduction to ecology. Studies of human ecology are integrated into the text, and the links to related disciplines are emphasised. The text begins with the ecology of individual organisms and moves on, through communities and ecosystems, to global considerations of biogeography, co-evolution and conservation. Case histories, historical perspectives, controversial theories and extension material are highlighted throughout the book. The second edition has been brought up to date with current syllabuses by the addition of further material on the key issue of conservation, giving excellent coverage of the principles of conservation and using case studies to provide examples of conservation policies in practice. The authors are experienced teachers of ecology at sixth form and undergraduate level.
