Available in PDF, EPUB and Kindle. Book excerpt: This book takes a non-technical approach in covering the evolution of South American mammalian fauna throughout geological history, and discusses how South America has changed due to mammalian invasions. Unlike other works on the subject, this book attempts to answer several crucial questions that often go unmentioned together in one cohesive monograph. What was the fauna like before the American interchange? What were the origins of the now-extinct groups when northern species arrived and out-competed them? How did the modern mammalian fauna come into being with such disparate animal groups? This information is given from a historical perspective throughout the book's 15 chapters, and is presented in an easily graspable fashion by mostly avoiding technical language. The book is written for academics, scientists and scholars engaged in paleontology, zoology and evolutionary biology, but may also appeal to a larger audience of general readers interested in mammalian evolution. The book begins with an introduction, describing the tools necessary to interpret the evolutionary history of South American mammals in geological terms and some of the early people who helped found South American mammalian paleontology. Chapter 2 describes the Mesozoic first mammals of Gondwana and what we are learning about them, dominant before the K/T extinction event. Then chapters 3 through 8 cover the Cenozoic, or "Age of Mammals", highlighting the major mammalian groups of South America that replaced the earlier mammals of Gondwana. These groups include the marsupials, native ungulates, the xenarthrans (armadillos, anteaters, sloths), the caviomorphs (rodents), and the platyrrhine monkeys. Chapters 9 and 10 address the Antarctic La Meseta fossils and the Colombian La Venta fossil faunal assemblages. Chapter 11 discusses the neotropical mammals that invaded the Caribbean Islands, and illustrates the influence South America has had on adjacent faunas. Chapter 12 describes the origin of the Amazon River and the role it has played in the evolution of the mammals and other flora and fauna. Chapter 13 tells the story of the Great American Biotic Interchange (GABI), and chapter 14 follows this up with a discussion of the Pleistocene mammal communities and their eventual extinction. Chapter 15 concludes the text by discussing the modern mammals of South America, and how despite the extensive Pleistocene extinctions there is still a lot of mammalian diversity in South America.

Available in PDF, EPUB and Kindle. Book excerpt: "One. The organization of a school of Jenkinsia is based on visual cues which become inoperative at just about the visual limit in man under certain conditions or before it under others. 2. Normally a school of Jenkinsia maintains a specified distance from solid vertical objects such as piles, and approaches twice as close to light-colored ones as to dark-colored. 3. The formation of a mill in Jenkinsia, typically based on extrinsic factors, may evidently under certain conditions be based on strictly intrinsic factors. 4. A mill of 3 feet in diameter of about 500 fish had members at the periphery traveling at about 3 inches per second. 5. Such a mill traveling around the wall of a circular tank traveled at the rate of about 1.4 feet per minute. 6. Individual fish near the center of a mill are more closely spaced than are those at its periphery. 7. A mill passing along a wall moves in a direction that a wheel would in rolling along a similar surface but with many more revolutions than a wheel would show without slipping. 8. Isolation of an individual or a small group for as short a time as a week will cause them to show reluctance to join a larger group. 9. Effects of weather such as rippled surface of the water or passing clouds tend to loosen the school, so that it is found in its most striking cohesive form close to the surface on days of clear skies and no wind. 10. Small differences in water temperature control the form and location of a school to a marked extent, certain isothermal lines acting as an effective barrier to the passage of such schools. 11. Within a school of somewhat mixed sizes there appears to be continual self-sorting, resulting in fish of the most nearly similar sizes being found together. 12. Aggressive behavior and aggregating tendencies are considered in theoretical terms in reference to school formation, simple aggregation, and solitary habits. 13. Further analytical suggestions are indicated with reference to future work extending to greater refinement of method than has been possible up to the present"--P. 25.

This book was released on 2013-12-01 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now well known that the concept of drifting continents became an estab lished theory during the 1960s. Not long after this "revolution in the earth sciences," researchers began applying the continental drift model to problems in historical biogeography. One such problem was the origin and dispersal of the New World monkeys, the Platyrrhini. Our interests in this subject began in the late 1960s on different conti nents quite independent of one another in the cities of Florence, Italy, and Berkeley, California. In Florence in 1968, A. B. Chiarelli, through stimulating discussions with R. von Koenigswald and B. de Boer, became intrigued with the possibility that a repositioning of the continents of Africa and South America in the early Cenozoic might alter previous traditional conceptions of a North American origin of the Platyrrhini. During the early 1970s this con cept was expanded and pursued by him through discussions with students while serving as visiting professor at the University of Toronto. By this time, publication of the Journal of Human Evolution was well underway, and Dr. Chiarelli as editor encouraged a dialogue emphasizing continental drift models of primate origins which culminated in a series of articles published in that journal during 1974-75. In early 1970, while attending the University of California at Berkeley, R. L. Ciochon was introduced to the concept of continental drift and plate tectonics and their concomitant applications to vertebrate evolution through talks with paleontologist W. A. Clemens and anthropologist S. L. Washburn.
