Book Description
"Wildlife in a Changing World" presents an analysis of the 2008 IUCN Red List of Threatened Species. Beginning with an explanation of the IUCN Red List as a key conservation tool, it goes on to discuss the state of the world s species and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world, highlighting the reasons behind their declining status. Areas of focus in the report include: freshwater biodiversity, the status of the world s marine species, species susceptibility to climate change impacts, the Mediterranean biodiversity hot spot, and broadening the coverage of biodiversity assessments."

Book Description
Drawn from a 2005 international symposium, these essays explore current tyrannosaurid current research and discoveries regarding Tyrannosaurus rex. The opening of an exhibit focused on “Jane,” a beautifully preserved tyrannosaur collected by the Burpee Museum of Natural History, was the occasion for an international symposium on tyrannosaur paleobiology. This volume, drawn from the symposium, includes studies of the tyrannosaurids Chingkankousaurus fragilis and “Sir William” and the generic status of Nanotyrannus; theropod teeth, pedal proportions, brain size, and craniocervical function; soft tissue reconstruction, including that of “Jane”; paleopathology and tyrannosaurid claws; dating the “Jane” site; and tyrannosaur feeding and hunting strategies. Tyrannosaurid Paleobiology highlights the far ranging and vital state of current tyrannosaurid dinosaur research and discovery. “Despite being discovered over 100 years ago, Tyrannosaurus rex and its kin still inspire researchers to ask fundamental questions about what the best known dinosaur was like as a living, breathing animal. Tyrannosaurid Paleobiology present a series of wide-ranging and innovative studies that cover diverse topics such as how tyrannosaurs attacked and dismembered prey, the shapes and sizes of feet and brains, and what sorts of injuries individuals sustained and lived with. There are also examinations of the diversity of tyrannosaurs, determinations of exactly when different kinds lived and died, and what goes into making a museum exhibit featuring tyrannosaurs. This volume clearly shows that there is much more to the study of dinosaurs than just digging up and cataloguing old bones.” —Donald M. Henderson, Royal Tyrrell Museum of Palaeontology

Book Description
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.

Book Description
The romantic landscapes and exotic cultures of Arabia have long captured the int- ests of both academics and the general public alike. The wide array and incredible variety of environments found across the Arabian peninsula are truly dramatic; tro- cal coastal plains are found bordering up against barren sandy deserts, high mountain plateaus are deeply incised by ancient river courses. As the birthplace of Islam, the recent history of the region is well documented and thoroughly studied. However, legendary explorers such as T.E. Lawrence, Wilfred Thesiger, and St. John Philby discovered hints of a much deeper past during their travels across the subcontinent. Drawn to Arabia by the magnifcent solitude of its vast sand seas, these intrepid adventurers learned from the Bedouin how to penetrate its deserts and returned with stirring accounts of lost civilizations among the wind-swept dunes. We now know that, prior to recorded history, Arabia housed countless peoples living a variety of lifestyles, including some of the world’s earliest pastoralists, c- munities of incipient farmers, fshermen dubbed the “Ichthyophagi” by ancient Greek geographers, and Paleolithic big-game hunters who were among the frst humans to depart their ancestral homeland in Africa. In fact, some archaeological investigations indicate that Arabia was inhabited by early hominins extending far back into the Early Pleistocene, perhaps even into the Late Pliocene.

Book Description
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.

Book Description
For the first two thirds of our evolutionary history, we hominins were restricted to Africa. Dating from about two million years ago, hominin fossils first appear in Eurasia. This volume addresses many of the issues surrounding this initial hominin intercontinental dispersal. Why did hominins first leave Africa in the early Pleistocene and not earlier? What do we know about the adaptations of the hominins that dispersed - their diet, locomotor abilities, cultural abilities? Was there a single dispersal event or several? Was the hominin dispersal part of a broader faunal expansion of African mammals northward? What route or routes did dispersing populations take?
