Available in PDF, EPUB and Kindle. Book excerpt: "Parallel evolution, the repeated, independent evolution of similar traits in similar environments, has played an important role in evolutionary biology, in part because repeated, habitat-associated divergence provides evidence for a deterministic role of natural selection in evolution. However, non-parallelism (variation in the direction or magnitude of divergence among ecotype pairs) has increasingly been reported in ostensibly parallel traits. In my thesis, I first demonstrate that non-parallelism is both common and underappreciated in studies of parallel evolution in fishes. The ubiquity of non-parallelism motivates my subsequent chapters, which investigate different potential drivers of non-parallelism in separate study systems. By comparing wild-caught and common-garden lake-stream stickleback (Gasterosteus aculeatus) from three evolutionary replicates, I show that plasticity is especially important in certain traits and in one replicate. In general, plasticity leads to greater parallelism in body shape than has been achieved by genetic divergence in these three watersheds. Next, I consider non-parallelism between the sexes in the body shape divergence between beach-creek spawning sockeye (Oncorhynchus nerka). My results suggest that sexual dimorphism leads to non-parallelism between the sexes to the extent that excluding either sex would lead to different conclusions regarding the extent of parallelism, which demonstrates the importance of considering individuals from both sexes in studies of parallel evolution. Finally, I investigate the role of evolutionary history in independent lineages of pink salmon (O. gorbuscha) in common habitats, and find that evolutionary history plays a relatively minor role in shaping migratory phenology, but does contribute to non-parallelism. Overall, my thesis points to the fact that although non-parallelism is underappreciated and rarely formally quantified, seeking to identify the drivers of non-parallelism could provide many valuable insights into the processes that shape adaptive divergence and speciation." --
Download or read book Ecology of North American Freshwater Fishes written by Stephen T. Ross Ph. D. and published by Univ of California Press. This book was released on 2013-06-01 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American freshwater fish fauna is the most diverse and thoroughly researched temperate fish fauna in the world. Ecology of North American Freshwater Fishes is the only textbook to provide advanced undergraduate and graduate students and researchers with an up-to-date and integrated view of the ecological and evolutionary concepts, principles, and processes involved in the formation and maintenance of this fauna. Ecology of North American Freshwater Fishes provides readers with a broad understanding of why specific species and assemblages occur in particular places. Additionally, the text explores how individuals and species interact with each other and with their environments, how such interactions have been altered by anthropogenic impacts, and the relative success of efforts to restore damaged ecosystems. This book is designed for use in courses related to aquatic and fish ecology, fish biology, ichthyology, and related advanced ecology and conservation courses, and is divided into five sections for ease of use. Chapter summaries, supplemental reading lists, online sources, extensive figures, and color photography are included to guide readers through the material and facilitate student learning. Part 1: Faunal origins, evolution, and diversity Presents a broad picture—both spatially and temporally—of the derivation of the fauna, including global and regional geological and climatological processes and their effects on North American fishes. Part 2: Formation, maintenance, and persistence of local populations and assemblages Focuses on how local fish populations and assemblages are formed and how they persist, or not, through time. Part 3: Form and function Deals with the relationship of body form and life history patterns as they are related to ecological functions. Part 4: Interactions among individuals and species Discusses the numerous interactions among individuals and species through communication, competition, predation, mutualism, and facilitation. Part 5: Issues in conservation Focuses on several primary conservation issues such as flow alterations and the increasing biotic homogenization of faunas.
Download or read book The Ecology of Adaptive Radiation written by Dolph Schluter and published by OUP Oxford. This book was released on 2000-08-31 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can cause a single ancestral species to differentiate into an impressively vast array of species inhabiting a variety of environments. Much of life's diversity has arisen during adaptive radiations. Some of the most famous recent examples include the East African cichlid fishes, the Hawaiian silverswords, and of course, Darwin's Gal--aacute--;pagos finches,. This book evaluates the causes of adaptive radiation. It focuses on the 'ecological' theory of adaptive radiation, a body of ideas that began with Darwin and was developed through the early part of the 20th Century. This theory proposes that phenotypic divergence and speciation in adaptive radiation are caused ultimately by divergent natural selection arising from differences in environment and competition between species. In The Ecology of Adaptive Radiation the author re-evaluates the ecological theory, along with its most significant extensions and challenges, in the light of all the recent evidence. This important book is the first full exploration of the causes of adaptive radiation to be published for decades, written by one of the world's best young evolutionary biologists.

Download or read book The Zoogeography of North American Freshwater Fishes written by Charles H. Hocutt and published by Wiley-Interscience. This book was released on 1986-04-30 with total page 888 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Zoogeography of North American Freshwater Fishes is a timely, authoritative monograph which serves a twofold purpose. First, it discusses the distribution of North American freshwater fish throughout the continent. It then attempts to explain these observed distribution patterns and develops a theory for the dispersal and evolution of these fishes through historical drainage alterations, plate tectonics, and Pleistoscene glaciation. The Zoogeography of North American Freshwater Fishes is a comprehensive treatment of the freshwater biogeography of North America, with implications for other disciplines. It stresses the intimate relationship between geological changes in the landscape on fish dispersal and evolution. For biologists, geologists, and geographers actively involved in biogeography, this book serves as a valuable-and practical-reference.
Download or read book Freshwater Fishes written by Lionel Cavin and published by Elsevier. This book was released on 2017-05-31 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 15,000 species, nearly a quarter of the total number of vertebrate species on Earth, freshwater fishes are extremely varied. They include the largest fish species, the beluga at over 7 meters long, and the smallest, the Paedocypris at just 8 millimeters, as well as the carnivorous, such as the piranha, and the calm, such as the Chinese algae eater. Certain species evolve rapidly, cichlids for example, while others transform very slowly, like lungfish. The fossils of these animals are very diverse in nature, sometimes just small scattered bones where sites correspond to ancient river beds or magnificent fossils of entire fish where there was once a lake. This book covers the history of these fishes over the last 250 million years by exploring the links between their biological evolution and the paleogeographic and environmental transformations of our planet, whether these be gradual or sudden. Gathers and synthetizes data from a vast number of publications regarding past freshwater assemblages and several fish lineages that invaded freshwaters Describes the work of the author's own team, concerning fauna from the Cretaceous of France, Morocco, and Thailand Presents the recent results of the tempo of diversification in freshwater environments and the evolutionary histories of clades and gar lineages
Download or read book The Evolutionary Biology of the Threespine Stickleback written by Michael A. Bell and published by Oxford University Press on Demand. This book was released on 1994 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threespine stickleback is a small fish of temperate coastal and fresh waters that exhibits extraordinary phenotypic diversity. Benefiting from its amenability to observation in the field and manipulation in the laboratory, Niko Tinbergen pioneered the threespine stickleback's use in behavioral studies and established it as a model system in ethology. This up-to-date volume incorporates reviews from active researchers who use studies of the fish to address a broad variety of evolutionary issues, including optimal foraging, armor variation, speciation, and the endocrine basis for correlated behavioral characters. The work demonstrates the value of viewing the biology of a single organism simultaneously from multiple perspectives. Students and researchers in ecology, evolution, animal behavior, and vertebrate zoology will find much of interest in this useful book.

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 Meat written by Sushmita Chatterjee and published by Duke University Press. This book was released on 2021-02-15 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is meat? Is it simply food to consume, or a metaphor for our own bodies? Can “bloody” vegan burgers, petri dish beef, live animals, or human milk be categorized as meat? In pursuing these questions, the contributors to Meat! trace the shifting boundaries of the meanings of meat across time, geography, and cultures. In studies of chicken, fish, milk, barbecue, fake meat, animal sacrifice, cannibalism, exotic meat, frozen meat, and other manifestations of meat, they highlight meat's entanglements with race, gender, sexuality, and disability. From the imperial politics embedded in labeling canned white tuna as “the chicken of the sea” to the relationship between beef bans, yoga, and bodily purity in Hindu nationalist politics, the contributors demonstrate how meat is an ideal vantage point from which to better understand transnational circuits of power and ideology as well as the histories of colonialism, ableism, and sexism.
