This practical handbook of reptile field ecology and conservation brings together a distinguished, international group of reptile researchers to provide a state-of-the-art review of the many new and exciting techniques used to study reptiles. The authors describe ecological sampling techniques and how they are implemented to monitor the conservation status and population trends of snakes, lizards, tuatara, turtles, and crocodilians throughout the world. Emphasis is placed on the extent of statistical inference and the biases associated with different techniques and analyses.The chapters focus on the application of field research and data analysis for achieving an understanding of reptile life history, population dynamics, movement patterns, thermal ecology, conservation status, and the relationship between reptiles and their environment. The book emphasises the need for thorough planning, and demonstrates how a multi-dimensional approach incorporates information related to morphology, genetics, molecular biology, epidemiology, statistical modelling, animal welfare, and biosecurity. Although accentuating field sampling, sections on experimental applications in laboratories and zoos, thermal ecology, genetics, landscape ecology, disease and biosecurity, and management options are included. Much of this information is scattered in the scientific literature or not readily available, and the intention is to provide an affordable, comprehensive synthesis for use by graduate students, researchers, and practising conservationists worldwide.

The Behavior Guide to African Mammals" is as different from a conventional field guide as motion pictures are from a snapshot. Whether we are able to look at them face to face, on television, or in the hundreds of illustrations provided here by Daniel Otte, this guide allows us to understand what animals do and what their behavior means. Drawing on his own extensive fieldwork and on the research of many other scientists, Richard Despard Estes describes and explains the behavior of four major groups of mammals. Estes'' remarkably informative guide is as up-to-date for the zoologist as it is accessible for the interested onlooker.

Horses, just horses--sans riders, saddles, and bridles--unless they're in a stall, it's not something you see anymore. But this is precisely what Tony Stromberg, equine photographer extraordinaire, gives us. He photographs these graceful animals in a pure and natural way that no other photographer can match. And now, his most beautiful shots are collected in one breathtaking photo book: Horses. Whether they're in stalls, in the paddock, or in fields and woods-Stromberg employs a perfect balance between light and shadow, unique composition, and a superlative feel for the right moment to make these majestic animals come alive, creating an authentic homage to a glorious creature. However, his pictures go far beyond merely depicting horses' beauty. Stromberg, a former advertising photographer, had his first encounters with horses in the 1990s at a time when he was suffering from terrible burnout himself. But in these gentle companions, he found in his words, teachers and soulmates who helped him regain a sense of peace. The deep connection to horses he has built since then is clearly evident in his photos, which is what makes them so special.

The fifth edition of this world-renowned guide provides detailed information on the origins, discovery, study, and conservation of Madagascars lemurs and comprehensive species accounts for all currently known taxa. The guide is illustrated with more than 600 drawings, photos, and maps to assist in field identification. It also introduces the concept of primate-watching and primate life-listing to encourage readers to see as many primates as possible in the wild and to help conserve them in their natural habitats.

Nuestra civilización se habría desarrollado de una forma diferente si no hubiesen existido los caballos, dada la inmensa influencia que este animal ha tenido en la marcha de la humanidad. De hecho, desde los albores de la historia, cuando el hombre lo transformo de apreciada presa en señorial y distinguido trono, el caballo se convirtio, en un periodo relativamente corto, en medio de transporte, herramienta de trabajo o maquina de guerra. Posteriormente, levantando pasiones y ambiciones, provoco inenarrables epopeyas, favorecio conquistas y migraciones y determino destinos y vivencias humanas. Al mismo tiempo inspiro a pintores y escultores, poetas y musicos, reflejando en su naturaleza y en sus formas las preferencias esteticas de cada civilizacion y cultura. En la mitologia, el caballo se fundio con el hombre dando origen a los centauros, y hasta fue dotado de alas como en los hipogrifos, mientras en realidad se fue adaptando en cada clima y a cada medio, acercandose cada vez mas a los usos y costubres de cada pueblo. Todavia hoy es enorme la influencia que en todo el mundo continua teniendo el caballo sobre nuestra forma de vivir,de hablar, de vestir, de pensar y hasta de soñar, lo que en el fondo es un testimonio de otros tiempos en los que el hombre y caballo no podian vivir el uno sin el otro.
