DOWNLOAD EBOOK →The horse has frequently been used as a classic example of long-term evolution because it possesses an extensive fossil record. This book synthesizes the large body of data and research relevant to an understanding of fossil horses from perspectives such as biology, geology, paleontology.

DOWNLOAD EBOOK →This book provides an update on the phylogeny, systematics and ecology of horses in South America based on data provided over the past three decades. The contemporary South American mammalian communities were shaped by the emergence of the Isthmus of Panama and by the profound climatic oscillations during the Pleistocene. Horses were a conspicuous group of immigrant mammals from North America that arrived in South America during the Pleistocene. This group is represented by 2 genera, Hippidion and Equus, which include small species (Hippidion devillei, H. saldiasi, E. andium and E. insulatus) and large forms (Equus neogeus and H. principale). Both groups arrived in South America via 2 different routes. One model designed to explain this migration indicates that the small forms used the Andes corridor, while larger horses used the eastern route and arrived through some coastal areas. Molecular dating (ancient DNA) suggests that the South American horses separated from the North American taxa (caballines and the New World stilt-legged horse) after 3.6 - 3.2 Ma, consistent with the final formation of the Panamanian Isthmus. Recent studies of stable isotopes in these horses indicate an extensive range of 13C values cover closed woodlands to C4 grasslands. This plasticity agrees with the hypothesis that generalist species and open biome specialist species from North America indicate a positive migration through South America.

DOWNLOAD EBOOK →Many students have only a limited knowledge of biology beforestarting a variety of equine courses, from BHS stages to NationalCertificate and Diploma and HND/degree. Introduction to HorseBiology provides all the information students of equine subjectsrequire, particularly those without a GCSE or A level inbiology. This book will be invaluable to all students of equine subjectsincluding First Diploma, National Diploma, National Certificate,Higher National Diploma and Higher National Certificate and allstudents studying for BHS or other equine related examinations. Itis also ideal for serious horse owners searching for a betterunderstanding of horses and how they function. The Author Zoe Davies is a former lecturer in equine science, a consultantequine nutritionist, author and external examiner for highereducation courses. She has substantial experience in equinemanagement and training.

The result is that climatic/tectonic events in earth history can now be placed in a more precise and global time frame, that permit their evaluation as abiotic causal factors which might trigger extinction and dispersal events in vertebrate history. Great strides have also been made in genetics and cell biology, providing new insight into phylogenetic relationships among many vertebrates. These new data, along with data on chronologie resolution of earth history, provide tests of previous interpretations regarding ancestral-descendant relationships based solely on the fossil record. It is fitting and proper that a volume on European Neogene mammal chronology is produced at this time, to ensure that new interpretations of vertebrate evolution and chronology are based on the most accurate and current data. Vertebrate paleon tologists believe that the fossil record is the only secure data for measuring the actual course and tempo of vertebrate evolution. Knowledge of the fossil record must keep pace with advances in other areas of science so that inferences on vertebrate evolu tion are accurate and meaningful.

DOWNLOAD EBOOK →This new treatise is comprised of 24 papers covering virtually every recent development regarding fossil horses, rhinos, tapirs, and their extinct relatives. It includes materials currently available in no other reference, such as information on the oldest known rhino and the oldest known perissodactyl, as well as papers debunking myths about the evolution of horses, and strong evidence that hyraxes are not related to elephants. The summary chapter includes useful charts which show the relationships of all perissodactyl genera, their distribution in time and space, and a new classification of the order.

Greece stands between 3 continents and its vertebrate fossil record is of great importance for paleontological and evolutionary studies in Europe, Asia and Africa. Fossils from classic, world-famous localities (e.g., Pikermi, Samos) form an essential part of the collections of the most important museums in the world and have been studied by numerous scientists. Recent paleontological research led to the discovery and study of numerous new sites. The volumes contain a taxonomic review of all named and identified taxa, their taxonomic history and current status, as well as historical, phylogenetic and biogeographic information. Volume 2 contains a synopsis of the fossil record and taxonomy of important groups of mammals represented in the fossil record of Greece. The volume starts with specific chapters on laurasiatherians like insectivores and bats, moving on to the main part of the book that deals with three of the most important fossil groups in the country. The fossil record of even-toed animals is summarized with chapters on bovids, cervids, suoids, anthracotheres, hippos, giraffes, and tragulids. The fossil record of odd-toed animals is presented with special chapters on horses, tapirs, rhinos, and chalicotheres. The last part of this volume deals with meat-eating, carnivoran groups, like felids, viverrids, hyaenas, canids, bears, ailurids, mephitids and mustelids. The volume ends with a special chapter on insular endemic mammals from the various islands of Greece.
