Available in PDF, EPUB and Kindle. Book excerpt: South American ecosystems suffered one of the greatest biogeographical events, after the establishment of the Panamian land bridge, called the “Great American Biotic Interchange” (GABI). This refers to the exchange, in several phases, of land mammals between the Americas; this event started during the late Miocene with the appearance of the Holartic Procyonidae (Huayquerian Age) in South America and continues today. The major phases of mammalian dispersal occurred from the Latest Pliocene (Marplatan Age) to the Late Pleistocene (Lujanian Age). The most important and richest localities of Late Miocene-Holocene fossil vertebrates of South America are those of the Pampean region of Argentina. There are also several Late Miocene and Pliocene localities in western Argentina and Bolivia. Other important fossils have been collected in localities of Pleistocene age outside Argentina: Tarija (Bolivia), karstic caves of Lagoa Santa and the recently explored caves of Tocantins (Brasil), Talara (Perú), La Carolina (Ecuador), Muaco (Venezuela), and Cueva del Milodon (Chile), among others. The book discusses basic information for interpreting the GABI such as taxonomic composition (incorporating the latest revisions) at classical and new localities for each stage addressing climate, environments, and time boundaries for each stage. It includes the chronology and dynamics of the GABI, the integration of South American mammalian faunas through time, the Quaternary mammalian extinctions and the composition of recent mammalian fauna of the continent.

Download or read book Conceptualization of xihuitl written by Mutsumi Izeki and published by BAR International Series. This book was released on 2008 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is concerned with how the Postclassic Mexica people developed their unique perspective of history and environment in a dynamic cultural context. By focusing on the process of conceptualization of the Nahuatl word 'xihuitl', the author analyzes the way the Mexica expressed their cognition. Xihuitl covers a range of meanings: 'turquoise', 'grass', 'solar year', 'comet', 'preciousness', 'blue-green' and 'fire'. The correlations of the meanings of xihuitl can be explained from a structural point of view. However, structural analysis does not reveal the dynamic experiential processes that produced such correlations in the minds of the Mexica. In order to account for this dynamic aspect of the concept, the author employs a theory drawn from cognitive science. This theory argues that the meanings and representations of a concept are metaphoric extensions that derive from the central sense of the concept. Applying this theory, the author examines the metaphoric extension of each xihuitl representation from the central sense. The author also analyzes the four media of expression-linguistic, iconographic, material and ritual-in which representations of xihuitl occur. The representations of xihuitl in each medium embody a particular aspect of the concept. At the same time, the concept as a whole was affected by the Mexica conceptual system-the way the Mexica saw their world-rooted in the connections they believed existed between themselves and those who established earlier Central Mexican civilizations.

Download or read book The Mastodonts of Brazil written by George Gaylord Simpson and published by . This book was released on 1957 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: "One. A large collection, mainly of isolated molars, from Águas do Araxá, Brazil, seems to represent a single population within a species identified as Haplomastodon waringi. The variation, described in some detail, is far greater than has hitherto usually been taken into consideration in the diagnosis of supposed species of mastodonts. 2. Mastodonts have been found at many localities scattered throughout Brazil. A few specimens are anomalous, but the great majority belong to, or are at least inseparable from, H. waringi on the basis of known characters. 3. Ecuadorian Haplomastodon is not at present specifically separable from H. waringi, and neither in Brazil nor in Ecuador is there good evidence of the presence of more than one species (or subgenus). 4. The only species and genera that now seem to be clearly distinct among South American mastodonts are Cuvieronius hyodon, Haplomastodon waringi, and Stegomastodon platensis. All these names have numerous synonyms. The species Stegomastodon superbus and the genus and species Notiomastodon ornatus are also tentatively listed as distinct, but are of doubtful status. 5. Haplomastodon is believed to be about as closely related to Cuvieronius as to Stegomastodon. 6. All the South American mastodonts seem to represent end terms of divergence within a single broad stock. Cuvieronius, Stegomastodon, and probably also Haplomastodon were already differentiated before they spread from North America to South America. The North American Rhynchotherium may belong to the same complex. All may ultimately have arisen from early Old World Anancinae, and all are tentatively referred to that subfamily"--P. 185.

Download or read book Amphibians and Reptiles of Baja California Including Its Pacific Islands and the Islands in the Sea of Cort s written by L. Lee Grismer and published by Univ of California Press. This book was released on 2002-09-16 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 and remote region. The culmination of Grismer's quarter century of fieldwork on the Baja peninsula and his exploration of more than one hundred of its islands in the Pacific Ocean and the Sea of Cortés, this book gives information on the identification, distribution, natural history, and taxonomy of each species of amphibian and reptile found there. Preliminary accounts of the life history of many of the salamanders, frogs, toads, turtles, lizards, and snakes are reported here for the first time, and several species that were almost unknown to science are illustrated in full color. The book also contains new data on species distribution and on the effect of the isolated landscape of the peninsula and its islands on the evolutionary process. Much of the information gathered here is presented in biogeographical overviews that consider the extremely varied environments of Baja California in both a contemporary and a historical framework. An original and important contribution to science, this book will generate further research for years to come as it becomes a benchmark reference for both professionals and amateurs.
