Download or read book Taxonomic Revision and Phylogenetic Analysis of the Flightless Mancallinae Aves Pan Alcidae written by N. Adam Smith and published by PenSoft Publishers LTD. This book was released on 2011-04-20 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flightless Mancallinae (Aves, Pan-Alcidae) from the Pacific Ocean are represented by one of the richest fossil records among Charadriiformes. A detailed review of previously published and previously undescribed fossils referred to Mancallinae resulted in taxonomic revision of the clade and the identification of three new species from the Miocene and Pliocene of California, USA. This monograph includes descriptions of new Mancallinae species and provides the first species-level phylogenetic hypothesis of Mancallinae relationships. Phylogenetic hypotheses were generated through the combined analysis of molecular sequence data and newly identified morphological character data for extant and extinct charadriiforms. The results of the combined phylogenetic analysis places hypotheses regarding the ethology and morphological convergence of Mancallinae to other flightless wing-propelled divers in phylogenetic context and facilitates comparisons between alcid paleodiversity and paleoclimatic events that have been hypothesized as drivers of alcid evolution.

This book was released on 1996-12-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: How were the tropical Americas formed? This ambitious volume draws on extensive, multidisciplinary research to develop new views of the geological formation of the isthmus linking North and South America and of the major environmental changes that reshaped the Neotropics to create its present-day marine and terrestrial ecosystems. Recent discoveries show that dramatic changes in climate and ocean circulation can occur very quickly, and that ecological communities respond just as rapidly. Abrupt changes in the composition of fossil assemblages, formerly dismissed as artifacts of a poor fossil record, now are seen as accurate records of swift changes in the composition of ocean communities. The twenty-four contributors use current work in paleontology, geology, oceanography, anthropology, ecology, and evolution to paint this challenging portrait of rapid environmental and evolutionary change. Their conclusions argue for a revision of existing interpretations of the fossil record and the processes—including invading Eurasian peoples—that have produced it.

Download or read book Phosphate Deposits of the World Volume 3 Neogene to Modern Phosphorites written by P. J. Cook and published by Cambridge University Press. This book was released on 1986 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of marine phosphorites, the principal raw material for phosphatic fertilizers, appears to be related mainly to marine biological productivity, often associated with upwelling currents during certain intervals of geological time. This book examines the environmental setting and resulting phosphorites which formed during the Miocene period, and investigations of modern oceanic environments where phosphorites are presently forming are also described.
