Tracker Manual by
This practical guide to animal tracking is a one-of-its-kind manual, based on
information developed with the help of southern Africa's few remaining traditional
trackers and their centuries-old wisdom in the fi eld.
It presents the more concrete and obvious wildlife signs for some 160 animals
and teams them with a host of seemingly unrelated details to give a comprehensive
picture of recent - and not-so-recent - traffic through the bush.

The Constituents of Medicinal Plants by
A classic in the literature of herbal medicine, this book explains in simple terms the commonly occurring chemical constituents of medicinal plants, and how these react with the human body. The major classes of plant constituents, such as phenols, terpenes and polysaccharides, are described both in terms of their chemical structures and their pharmacological activities.
The last 20 years has seen huge growth in research output in phytochemistry, and this edition has been thoroughly revised to incorporate up-to-date research. It contains a new chapter on resins and cannabinoids, and additional content on macrocarpals, essential oil chemotypes, mushroom polysaccharides, phytochemical synergy, and toxicology of phytochemicals
Two Oceans by

The most frequently encountered species of this rich assemblage - fish to whales, algae to sponges, and seaweeds to dune forests - are covered in detail in this newly revised and comprehensively updated edition of the best-selling Two Oceans - A Guide to the Marine Life of Southern Africa.
