Download or read book Geology of U S Parklands written by Eugene P. Kiver and published by John Wiley & Sons. This book was released on 1999-06-15 with total page 916 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating and accessible introduction to the principles of physical and historical geology. For the millions who visit them each year, U.S. national parklands offer a glittering spectacle of natural wonders. But beyond the spectacular scenery, these national treasures have a much bigger, more awe-inspiring tale to tell--a sprawling story of upheaval and transformation, involving forces and time-spans almost beyond imagining. The purpose of this book is to provide you with the knowledge you need to read and interpret that story, and to make visits to the parklands even more special. Requiring no prior familiarity with the geological sciences, this region-by-region exploration of the U.S. parklands teaches the principles of physical and historical geology by example. It begins with a general introduction to all important concepts, terms, and principles. In the chapters that follow, the authors take you on a tour through the geological regions of the United States. Beginning with Hawaii and the Pacific borderlands and moving progressively eastward to the Appalachian Mountains and the coastal plains of the East Coast, they provide you with a geologist's-eye view of the landforms, mountains, and bodies of water encountered in over 70 national parks and monuments, and tell the fascinating story of their evolution. Lavishly illustrated with nearly 300 stunning photographs and maps and featuring greatly expanded coverage of the geological story, history, and culture of U.S. parks and monuments, this new edition of Dr. David Harris's classic text is an ideal introduction to the principles of geology for students and nature enthusiasts alike.

Download or read book Biology and Conservation of Musteloids written by David W. Macdonald and published by Oxford University Press. This book was released on 2017-11-17 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: The musteloids are the most diverse super-family among carnivores, ranging from little known, exotic, and highly-endangered species to the popular and familiar, and include a large number of introduced invasives. They feature terrestrial, fossorial, arboreal, and aquatic members, ranging from tenacious predators to frugivorous omnivores, span weights from a 100g weasel to 30kg giant otters, and express a range of social behaviours from the highly gregarious to the fiercely solitary. Musteloids are the subjects of extensive cutting-edge research from phylogenetics to the evolution of sociality and through to the practical implications of disease epidemiology, introduced species management, and climate change. Their diversity and extensive biogeography inform a wide spectrum of ecological theory and conservation practice. The editors of this book have used their combined 90 years of experience working on the behaviour and ecology of wild musteloids to draw together a unique network of the world's most successful and knowledgeable experts. The book begins with nine review chapters covering hot topics in musteloid biology including evolution, disease, social communication, and management. These are followed by twenty extensive case studies providing a range of comprehensive geographic and taxonomic coverage. The final chapter synthesises what has been discussed in the book, and reflects on the different and diverse conservation needs of musteloids and the wealth of conservation lessons they offer. Biology and Conservation of Musteloids provides a conceptual framework for future research and applied conservation management that is suitable for graduate level students as well as professional researchers in musteloid and carnivore ecology and conservation biology. It will also be of relevance and use to conservationists and wildlife managers.

Download or read book Fossil Legends of the First Americans written by Adrienne Mayor and published by Princeton University Press. This book was released on 2023-04-11 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: The burnt-red badlands of Montana's Hell Creek are a vast graveyard of the Cretaceous dinosaurs that lived 68 million years ago. Those hills were, much later, also home to the Sioux, the Crows, and the Blackfeet, the first people to encounter the dinosaur fossils exposed by the elements. What did Native Americans make of these stone skeletons, and how did they explain the teeth and claws of gargantuan animals no one had seen alive? Did they speculate about their deaths? Did they collect fossils? Beginning in the East, with its Ice Age monsters, and ending in the West, where dinosaurs lived and died, this richly illustrated and elegantly written book examines the discoveries of enormous bones and uses of fossils for medicine, hunting magic, and spells. Well before Columbus, Native Americans observed the mysterious petrified remains of extinct creatures and sought to understand their transformation to stone. In perceptive creation stories, they visualized the remains of extinct mammoths, dinosaurs, pterosaurs, and marine creatures as Monster Bears, Giant Lizards, Thunder Birds, and Water Monsters. Their insights, some so sophisticated that they anticipate modern scientific theories, were passed down in oral histories over many centuries. Drawing on historical sources, archaeology, traditional accounts, and extensive personal interviews, Adrienne Mayor takes us from Aztec and Inca fossil tales to the traditions of the Iroquois, Navajos, Apaches, Cheyennes, and Pawnees. Fossil Legends of the First Americans represents a major step forward in our understanding of how humans made sense of fossils before evolutionary theory developed.

Download or read book Lothagam written by Meave G. Leakey and published by Columbia University Press. This book was released on 2003-01-23 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: Located at the southwest corner of Lake Turkana in northern Kenya, Lothagam represents one of the most important intervals in African prehistory. Early human remains are restricted in distribution to Africa and the acquisition of an upright bipedal striding gait, the hallmark of humanity, appears to be at least circumstantially linked to the reduction of equatorial forests and the spread of grasslands on that continent. The diverse Lothagam fauna documents the end-Miocene transition from forested to more open habitats that were exploited by grazing horses and antelopes, hippos, giant pigs, and true elephants. It also includes spectacularly complete fossil carnivore skeletons and some of the oldest human remains. Enlisting a team of highly qualified specialists, this book provides the geologic context and dating framework for the Lothagam fossiliferous sequences, describes the immense diversity of vertebrate fossils recovered from the Late Miocene and Early Pliocene sediments, and synthesizes the results to interpret the changing paleoenvironments that prevailed at this site. The book will interest anthropologists, paleontologists, geologists, and anyone interested in human origins.

Download or read book Timetrees Incorporating Fossils and Molecules 2nd edition written by Michel Laurin and published by Frontiers Media SA. This book was released on 2022-09-15 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calibrating phylogenies to time is central to addressing many questions in evolutionary biology and macroevolution. The fossil record once provided our only source for establishing a timeline for evolution. However, the incompleteness of the fossil record and the non-uniformity of fossil recovery rate make it challenging to obtain precise estimates of divergence times from fossil evidence alone. Molecular dating, which combines evidence from the geological and molecular records, enables us to generate a much more complete and precise timeline of events. The molecular clock can be time-calibrated using temporal evidence from fossils and used to estimate divergence times based on the assumption that the rate of sequence evolution will be approximately constant over time and among lineages. Methodological challenges to applying this concept in practice have been to relax the assumption of constant evolutionary rates and to model the uncertainty associated with paleontological and geological calibrations. To this end, available statistical methods have become increasingly complex in order to capture key features of empirical data. These are typically applied using Bayesian inference, which provides a powerful framework for incorporating multiple sources of uncertainty. Although overall more effort has been expended in developing models of molecular sequence evolution, critical advances have also included approaches to modeling taxonomic diversification and fossilization. In particular, recent advances in birth-death process models have allowed for continuous sampling along lineages, enabling more information from the fossil record to be incorporated into dating analyses in a statistically coherent way. In addition, available dating methods can now be applied to scenarios in which no molecular data may be available, allowing for novel insights into the evolution of entirely extinct clades. Other recent innovations enable us to date divergence times among taxa that have no fossil record, including the use of gene duplication events or biogeographic evidence. Furthermore, time-calibrated trees are necessary for obtaining phylogenetic estimates of taxonomic diversification and extinction rates, which can now be jointly inferred along with lineage divergence times. These approaches offer an exciting opportunity to understand the evolution of life in deep time, although key challenges remain, especially with regards to modeling the processes of genome evolution, taxonomic diversification and fossil recovery. In this Research Topic, we focus on recent advances in methodology, outstanding challenges, and the application of molecular and paleontological dating methods to empirical case studies across the Tree of Life.
