Available in PDF, EPUB and Kindle. Book excerpt: Pantosteus, a subgenus of Catostomus, includes the mountain sucker (Catostomus playthyrnchus), whose speculated older origins in the Miocene/Pliocene can provide insight into the ancient geographical events of western North America. We believe that major geologic events influencing the diversification of mountain suckers include the rise of the Colorado Plateau, the connections between the ancient Snake River system and the Lahontan system and subsequently the connection of the Snake River system to the Columbia Basin, dispersal of mountain suckers across the continental divide, as well as the Pleistocene Bonneville flood. If this is true, we should see evidence of geologic separation and timing through studying the phylogenetics of the mountain sucker. In order to clarify relationships of the mountain sucker with respect to other Pantosteus species, we examined cytochrome b (cyt b) sequences for 144 mountain suckers, 24 other Pantosteus species, and ten outgroup species. Phylogenetic relationships among haplotypes were constructed based on maximum likelihood and Bayesian criterion. In an effort to provide better resolution at some nodes, we also sequenced additional mitochondrial genes (ND1, ND2, ATPase, ND4L, ND4, ND5, ND6, and cyt b) for a subset of 44 individuals taken from the major clades obtained from the cyt b phylogentic analyses. Trees from this data set were also constructed under maximum likelihood and Bayesian criterion. All phylogenetic analysis revealed that mountain sucker are paraphyletic, with two major clades of mountain suckers separated by other members of the subgenus Pantosteus. One clade included two sub-clades, one from the upper Snake River drainage/northern Bonneville/Green River drainage Basins and the other from the southern Bonneville Basin. The other major clade included sub-clades from the Lahontan Basin, Columbia River Basin, and Upper Missouri River Basin. Molecular clock analysis revealed that Pantosteus likely split from Catostomus during the Miocene and that major speciation events within Pantosteus occurred during the Pliocene and Pleistocene. Genetic structuring and gene flow estimates for mountain sucker populations, with groupings based on major drainage basins, were calculated with AMOVA and Fst estimates in Arlequin and revealed that most of the genetic structuring was explained by variation among drainage basins with limited gene flow occurring between drainage basins. Based on this study, the role of the Colorado Plateau's geologic history in the evolution of the mountain sucker remains unclear. However, all other geologic events as discussed in this study seem to have played a significant role in the evolution of the mountain sucker.
Download or read book Phylogeography of California written by Kristina A. Schierenbeck and published by Univ of California Press. This book was released on 2014-08-26 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phylogeography of California examines the evolution of a variety of taxaÑancient and recent, native and migratoryÑto elucidate evolutionary events both major and minor that shaped the distribution, radiation, and speciation of the biota of California. The book also interprets evolutionary history in a geological context and reviews new and emerging phylogeographic patterns. Focusing on a region that is defined by physical and political boundaries, Kristina A. Schierenbeck provides a phylogeographic survey of CaliforniaÕs diverse flora and fauna according to their major organismal groups. Life history and ecological characteristics, which play prominent roles in the various outcomes for respective clades, are also considered throughout the work. Supporting scholars and researchers who study evolutionary diversification, the book analyzes research that helps assess one of the major challenges in phylogeographic studies: understanding changes in population structures shaped by geological and geographical processes. California is one of only twenty-five acknowledged biological hotspots worldwide, and the phylogeographic history of the state can be extrapolated to study other regions in western North America. Further consideration is given to implications for conservation, recommendations concerning the biogeographic provinces that roughly define the state of California, and predictions related to climate change.

Download or read book The Ecology of Marine Fishes written by Dr. Larry G. Allen and published by Univ of California Press. This book was released on 2006-02-15 with total page 1353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes have been intensively studied, and some of the fundamental ideas in the science of marine ecology have emerged from the body of knowledge derived from this diverse group of organisms. This unique, authoritative, and accessible reference, compiled by 35 luminary ecologists, evolutionary biologists, and ichthyologists, provides a synthesis and interpretation of the large, often daunting, body of information on the ecology of marine fishes. The focus is on the fauna of the eastern Pacific, especially the fishes of the California coast, a group among the most diverse and best studied of all marine ecosystems. A generously illustrated and comprehensive source of information, this volume will also be an important launching pad for future research and will shed new light on the study of marine fish ecology worldwide. The contributors touch on many fields in biology, including physiology, development, genetics, behavior, ecology, and evolution. The book includes sections on the history of research, both published and unpublished data, sections on collecting techniques, and references to important earlier studies.
Download or read book Standing between Life and Extinction written by David L. Propst and published by University of Chicago Press. This book was released on 2021-02-15 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American deserts—lands of little water—have long been home to a surprising diversity of aquatic life, from fish to insects and mollusks. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In this book, conservationists dedicated to these creatures document the history of their work, the techniques and philosophies that inform it, and the challenges and opportunities of the future. A precursor to this book, Battle Against Extinction, laid out the scope of the problem and related conservation activities through the late 1980s. Since then, many nascent conservation programs have matured, and researchers have developed new technologies, improved and refined methods, and greatly expanded our knowledge of the myriad influences on the ecology and dynamics of these species. Standing between Life and Extinction brings the story up to date. While the future for some species is more secure than thirty years ago, others are less fortunate. Calling attention not only to iconic species like the razorback sucker, Gila trout, and Devils Hole pupfish, but also to other fishes and obscure and fascinating invertebrates inhabiting intermittent aquatic habitats, this book explores the scientific, social, and political challenges of preserving these aquatic species and their habitats amid an increasingly charged political discourse and in desert regions characterized by a growing human population and rapidly changing climate.
Download or read book Inland Fishes of the Greater Southwest written by W. L. Minckley and published by University of Arizona Press. This book was released on 2009 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive new book replaces and substantially expands upon the landmark Fishes of Arizona, which has been the authoritative source since it was first published in 1973. Inland Fishes of the Greater Southwest is a one-volume guide to native and non-native fishes of the lower Colorado River basin, downstream from the Grand Canyon, and of the northern tributaries of the Sea of Cortez in the United States and Mexico. In all, there are in-depth accounts of more than 165 species representing 30 families. The book is not limited to the fish. It provides insights into their aquatic world with information on topography, drainage relations, climate, geology, vegetational history, aquatic habitats, human-made water systems, and conservation. A section of the book is devoted to fish identification, with keys to native and non-native families as well as family keys to species. The book is illustrated with more than 120 black-and-white illustrations, 47 full-color plates of native fishes, and nearly 40 maps and figures. Many native fish species are unique to the Southwest. They possess interesting and unusual adaptations to the challenges of the region, able to survive silt-laden floods as well as extreme water temperatures and highly fluctuating water flows ranging from very low levels to flash floods. However, in spite of being well-adapted, many of the fish described here are threatened or endangered, often due to the acts of humans who have altered the natural habitat. For that reason, Inland Fishes of the Greater Southwest presents a vast amount of information about the ecological relationships between the fishes it describes and their environments, paying particular attention to the ways in which human interactions have modified aquatic ecosystemsÑand to how humans might work to ensure the survival of rapidly disappearing native species.

Download or read book Mammalogy written by George A. Feldhamer and published by JHU Press. This book was released on 2015-01-15 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the expertise and perspective of five leading mammalogists, the fourth edition of Mammalogy: Adaptation, Diversity, Ecology significantly updates taxonomy, includes a new chapter on mammalian molecular phylogenetics, and highlights several recently described species. There are close to 5,500 species in the class Mammalia, including the blue whale—the largest animal that has ever lived—and the pygmy shrew, which weighs little more than a penny. The functional diversity of mammals has allowed them to play critical roles in every ecosystem, whether marine, freshwater, alpine, tundra, forest, or desert. Many mammal species are critically endangered and present complex conservation and management challenges. This book touches on those challenges, which are often precipitated by overharvesting and habitat loss, as well as emerging threats, such as the impact of wind turbines and white nose syndrome on bats and chronic wasting disease on deer. Among the updates and additions to the fourth edition of Mammalogy are numerous new photos, figures, and cladograms, over 4,200 references, as well as • A completely new chapter on mammalian phylogeny and genomics • Current taxonomy—including major changes to orders, suborders, and superfamilies of bats and rodents • An explanation of the recent inclusion of whales with terrestrial even-toed ungulates • Updates on mammalian structural, functional adaptations, and fossil history • recent advances in our understanding of phylogeny, biogeography, social behavior, and ecology • A discussion of two new orders and thirteen newly recognized extant families • Reflections on the implications of climate change for mammals • Thorough examinations of several recently described species, including Durrell's vontsira (Salanoia durrelli) and the Laotian rock rat (Laonastes aenigmamus) • An explanation of mammalian biomechanics, such as that seen in lunge feeding of baleen whales • Breakout boxes on unique aspects of mammals, including the syntax of bat songs, singing mice, and why there are no green mammals (unless we count algae-covered sloths) Maintaining the accessible, readable style for which Feldhamer and his coauthors are well known, this new edition of Mammalogy is the authoritative textbook on this amazingly diverse class of vertebrates.

Download or read book Oaks Physiological Ecology Exploring the Functional Diversity of Genus Quercus L written by Eustaquio Gil-Pelegrín and published by Springer. This book was released on 2017-12-12 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future.
