DOWNLOAD EBOOK →Monitor lizards (genus Varanus) have attracted a great deal of interest--these large and impressive lizards are often the centerpiece of reptile house exhibits. Monitors tend to be fairly wary and difficult to observe--therefore they are not particularly tractable research subjects, but they have nevertheless received an extraordinary amount of attention from devoted students.Varanoid Lizards of the World is a comprehensive account of virtually everything important that is known about monitor lizards, beginning with detailed species accounts and proceeding to various modern comparative analyses. Where possible, people who have had detailed field experience with a particular species have assembled species accounts. In the process of reporting what is known, we also identify what remains to be learned about these lizards. We hope to establish a prototype showing how such a diverse monophyletic group can be exploited both to identify and to understand the actual course of evolution. As such, this effort becomes a protocol for future workers to follow for other groups of closely-related species.

Although the authors pay particular attention to reproductive behavior, from initial recognition and evaluation of potential partners to decisions about reproduction, they also deal with other survival behaviors.

DOWNLOAD EBOOK →This book presents perspectives on the past and present state of the understanding of snake origins. It reviews and critiques data and ideas from paleontology and neontology (herpetology), as well as ideas from morphological and molecular phylogenetics. The author reviews the anatomy and morphology of extant snakes. Methods are also critiqued, including those empirical and theoretical methods employed to hypothesize ancestral ecologies for snakes. The modern debate on squamate phylogeny and snake ingroup phylogeny using molecules and morphology is examined critically to provide insights on origins and evolution. Key Features Important major evolutionary transformation in vertebrate evolution Continuing historical debate in vertebrate paleontology Of wide interest to a core audience of paleontologists, herpetologists, and morphologists Author acknowledged as prominent contributor to debate over snake origins Based on remarkable well preserved fossil specimens

DOWNLOAD EBOOK →The early Mesozoic period was a critical period in the evolution of life on land when most of todays major groups of terrestrial vertebrates arose and dinosaurs and pterosaurs rose to prominence. In recent years this period has received a great deal of attention from palaeontologists, and it is now felt that the small vertebrates which lived in the shadows of the first dinosaurs tell us a great deal about the evolution of modern terrestrial ecosystems. This book is an attempt to collate all the information on the small vertebrates and features contributions by experts with international reputations in their fields. There are chapters on the taxonomy and phylogeny of the key vertebrate groups followed by a section dealing with the most significant fossiliferous assemblages worldwide. The final section looks at how faunal turnover at this time is measured and examines the possibility of mass extinctions.

DOWNLOAD EBOOK →Deserts, whether hot or cold, are considered to be one of the most difficult environments for living systems, lacking the essential free water which ac counts for approximately 60-70% of their body mass and more than 98% of their constituent atoms {Macfarlane 1978}. Amongst vertebrates, reptiles are usually thought of as the animals most adapted or suited to such environments because of their diurnal habit, based on a need for external heat, and their ability to survive far from obvious sources of water. This impression is rein forced when one examines the composition of vertebrate faunae characteristic of deserts and arid zones: reptiles predominate and they are often the only vertebrates to be found in hyper-arid areas, such as some parts of the Sahara {Monod 1973}. I recently had occasion to examine this assumption carefully, however, and was led inexorably to the conclusion that reptiles represent a particularly successful desert group, not because of their evolution of superior adaptations, but because of their possession of a basic suite of behavioural and physiologi cal characteristics that suit them uniquely to this very resource-limited environment {Bradshaw 1986a}. These fundamental reptilian characteristics are: 1. their low rates of metabolism, compared with birds and mammals, which result in extremely low rates of resource utilisation and lead to considerable economy in the handling of water 2.

DOWNLOAD EBOOK →Evolutionary Biology, of which this is the twenty-second volume, continues to offer its readers a wide range of original articles, reviews, and commentaries on evolution, in the broadest sense of that term. The topics of the reviews range from anthropology, molecular evolution, and paleobiology to principles of systematics. In recent volumes, a broad spectrum of articles have appeared on such subjects as asymmetric sexual isolation, biochemical systematics in plants, species selection, DNA hybridization and phylogenetics, modes of evolution in Pleistocene rodents, and development and evolution of the vertebrate limb. We have also attempted to provide a forum for con flicting ideas. Articles such as these, often too long for standard journals, are the material for Evolutionary Biology. The editors continue to solicit manuscripts on an international scale in an effort to see that everyone ofthe many facets of biological evolution is covered. Manuscripts should be sent to anyone of the following: Max K.
