Key to the Herpetofauna of the Continental United States and Canada
This profusely illustrated comprehensive key for identifying amphibians and reptiles from the continental United States and Canada incorporates a wealth of scientific findings. Since the first edition was published in 1998 and the second in 2012, the number of currently recognized species of native amphibians and reptiles in the area covered by this key has increased from 545 to 634 to 685, and the number of established non-native species has increased from 39 to 58 to 67. The increase in native taxa reflects the dynamic nature of modern systematics and the use of new (especially molecular) techniques to elucidate relationships and redefine species boundaries. The increase in non-native spec...
Amphibians and Reptiles of Baja California, Including Its Pacific Islands and the Islands in the Sea of Cortés
The Baja California peninsula is home to many forms of life found nowhere else on earth. This, combined with the peninsula's rugged and inaccessible terrain, has made the area one of the last true biological frontiers of North America. L. Lee Grismer is not only the foremost authority on the amphibians and reptiles of Baja California, but also an outstanding photographer. He has produced the most comprehensive work on the herpetofauna of the peninsula and its islands ever published. With its stunning color images, detailed accounts of many little-known species, and descriptions of the region's diverse environment, this is the definitive guide to the amphibians and reptiles of a fascinating a...

Intersexuality in the Animal Kingdom
When Richard Goldschmidt' coined the term "intersexuality" in 1915, he intended it to apply to normally dioecious species which exhibit some kind of mixture between male and female characters. However, as knowledge of the bewildering variability present in the sexual orga nization of members of the animal kingdom has increased, the original meaning of the word has changed. Today many authors define inter sexuality as "the presence of both male and female characteristics, or of intermediate sexual characteristics, in a single individual".2 This more extensive and widely accepted concept justifies the title of our book •. Among all the anatomical and physiological features of living organism...
Alle Reptilien der Welt
Wie kommt man auf die Idee, alle Reptilien der Welt inklusive der Unterarten aufzulisten und allen Reptilien deutsche Namen zu geben? Es gibt einen Grund dafür - mein Lieblingsspruch, dessen Verfasser unbekannt ist: "Alle sagten, das geht nicht - dann kam einer, der wusste das nicht und tat es einfach!" Ich bin Tierfotograf und wohl auch ein wenig verrückt. Ich habe in den letzten zehn Jahren eine komplette Tierdatenbank für Säugetiere, Vögel und Reptilien aufgebaut. Das erleichtert mir die Arbeit bei der Bestimmung, der Bildarchivierung und Stichwortvergabe, vor allem bei den vielen Unterarten. Warum nun die Reptilien der Welt in Buchform? Mit diesem Buch möchte ich allen Tier-Freunde...

Biotic Evolution and Environmental Change in Southeast Asia
The flora and fauna of Southeast Asia are exceptionally diverse. The region includes several terrestrial biodiversity hotspots and is the principal global hotspot for marine diversity, but it also faces the most intense challenges of the current global biodiversity crisis. Providing reviews, syntheses and results of the latest research into Southeast Asian earth and organismal history, this book investigates the history, present and future of the fauna and flora of this bio- and geodiverse region. Leading authorities in the field explore key topics including palaeogeography, palaeoclimatology, biogeography, population genetics and conservation biology, illustrating research approaches and themes with spatially, taxonomically and methodologically focused case studies. The volume also presents methodological advances in population genetics and historical biogeography. Exploring the fascinating environmental and biotic histories of Southeast Asia, this is an ideal resource for graduate students and researchers as well as environmental NGOs.
