Every biological system is the outcome of its evolution; therefore, the deciphering of its evolutionary history is of tremendous importance to understand the biology of a system. Since 1997 scientists of different disciplines have held an annual "Evolutionary Biology Meeting" at Marseille (France) in order to discuss their research developments, exchange ideas and start collaborations. Consisting of the most representative talks of the 11th meeting, this book provides an up-to-date overview of evolutionary concepts and how these concepts can be applied to a better understanding of various biological aspects. It is divided into the following four parts: Modelization of Evolution - Concepts in Evolutionary Biology - Knowledge - Applied Evolutionary Biology. This book is an invaluable source of information not only for evolutionary biologists, but also for biologists in general.
Inspired by an intrinsic and powerful passion for horses, Lloyd Gillespie and Isabel Wolf- Gillespie set off on a life changing epic adventure journey across the far corners of South Africa eventually covering a total of over 7411 kilometers. Theirs is a story of determination, commitment, humility and love on an inspiring journey alongside their horses. There is a very interesting and often at times trying relationship dynamic between the different personalities. On the one hand there is the relationship between humans, between humans and horses and between horses themselves, all the while faced with a variety of challenges and difficulties with the result being a life changing experience.The book is written from a South African male and German female perspective sharing the extreme conditions of traveling in the African wilderness for one year and 7 months alongside a herd of horses!
Fully revised and updated, Filmer’s Spiders: an Identification Guide to Southern Africa features all 63 families of spider that occur in this region. A fresh layout, full-colour photographs throughout – many of them new – and diagrams of diagnostic features make this a quick and easy guide for use in the field. The spiders are grouped into web-living, ground-living and plant-Iiving species to aid identification. Each family is described in terms of the spiders’ lifestyle, habitat, size, behaviour and venom potential, and the best collecting methods are given in each case. For those species whose venom is potentially harmful to man, the effects and recommended treatment of bites are discussed. This handy format book will appeal to anybody wishing to gain insight into the daily lives of spiders.
Scorpions have captured the imagination of humans from early times, arousing a morbid interest that no doubt stems from their venomous tendencies. Misunderstood and persecuted as they often are, it is only relatively recently that we have begun to understand their complex behaviour and biology. This book, written by one who confesses to a passion for scorpions, describes in layman's terms the way scorpions' bodies are constructed, the strategies that enable them to survive harsh conditions, their use of venom and other aspects of their successful existence over millions of years. It will help amateur naturalists as well as professionals in associated fields to identify southern Africa's rich scorpion fauna and, it is hoped, will shed new light on these secretive creatures. The species included here are those most likely to be encountered. Many are readily identifiable with the naked eye and have very wide distributions. As far as possible, the book avoids complicated terminology and includes practical information on where to look for scorpions and how best to handle them.
"This book is intended to introduce readers to the great beauty, diversity and ecological importance of South African insects as found on the so-called Diamond Route. This is a range of nine properties scattered across South Africa that are owned by De Beers and the Oppenheimer family and that exist primarily to promote conservation and research. The invertebrates investigated in this book were observed in the range of habitat types found on the Diamond Route, which include mopane woodland, riverine forest, bankenveld grasslands and the evocative sandscapes of the Kalahari."--P. xv.
Among the world’s most fascinating living fossils, scorpions have been around for some 420 million years. South Africa is home to an astonishing variety, with 108 species in three families occurring in most of the region’s biomes, from desert and grassland to fynbos, savanna and forest. Scorpions are even found in urban gardens. Field Guide to Scorpions of South Africa is the first comprehensive guide to describe and illustrate all known species in the country. The clear, detailed species accounts cover appearance, habitat and behaviour, and discuss the variation within species according to region. Up-to-date distribution maps are included for all species and exceptional photographs, car...
