The fish faunas of continental South and Central America constitute one of the greatest concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living vertebrate species. Historical Biogeography of Neotropical Freshwater Fishes explores the evolutionary origins of this unique ecosystem. The chapters address central themes in the study of tropical biodiversity: why is the Amazon basin home to so many distinct evolutionary lineages? What roles do ecological specialization, speciation, and extinction play in the formation of regional assemblages? How do dispersal barriers contribute to isolation and diversification? Focusing on whole faunas rather than individual taxonomic groups, this volume shows that the area’s high regional diversity is not the result of recent diversification in lowland tropical rainforests. Rather, it is the product of species accumulating over tens of millions of years and across a continental arena.
"Of all the literature I use while preparing field guides for the Food and Agriculture Organization of the United Nations, Nelson's Fishes of the World is, by far, the one I refer to most often. [This] book is a standard reference . . . I continue to use it extensively in the ichthyology courses I teach, particularly in laboratory sessions." -Kent E. Carpenter Old Dominion University "Fishes of the World is a unique and essential resource for anyone seriously interested in the diversity and evolution of fishes. The family accounts provide quick summaries of current knowledge on all groups of living fishes and many key fossil taxa. It is a required work for every student in my laboratory." -W...
The Amazon and Orinoco basins in northern South America are home to the highest concentration of freshwater fish species on earth, with more than 3,000 species allotted to 564 genera. Amazonian fishes include piranhas, electric eels, freshwater stingrays, a myriad of beautiful small-bodied tetras and catfishes, and the largest scaled freshwater fish in the world, the pirarucu. Field Guide to the Fishes of the Amazon, Orinoco, and Guianas provides descriptions and identification keys for all the known genera of fishes that inhabit Greater Amazonia, a vast and still mostly remote region of tropical rainforests, seasonally flooded savannas, and meandering lowland rivers. The guide’s contribut...
The cichlid fishes are an important group, being widely used in scientific research and as popular fish with aquarists. This group contains mainly small species which adjust quickly to captivity, exhibiting a readiness to breed and long periods of parental care for the young. This books comprehensive volume describes the current knowledge on the behaviour and ecology of the cichlid fishes.
#1 in the Saxon mystery series. Introducing L.A.-based private eye Saxon. A transplanted Easterner trying to make it as an actor, Saxon stays solvent (and sane) between roles by running an investigating agency. When someone takes a potshot at famous pulp detective writer Buck Weldon, Saxon agrees to help—especially after meeting Weldon’s tall blonde daughter. Turns out, the writer’s enemy list is longer than some of his novels and is headed by his agent, his publisher, and one of the biggest producers in Hollywood. Baffling leads involve a major cocaine dealer and a professor specializing in private eye literature. Saxon’s investigation takes him from Westwood to Palm Springs and back to the San Fernando Valley before its violent culmination in a backwater Mexican village on the Baja peninsula.
The Hormones: Physiology, Chemistry, and Applications, Volume V provides information pertinent to the nature and function of hormones. This book provides a variety of topics, including pituitary hormones, thyroid, thyroid hormones, mammalian hormones, tumors and hormones, and some problems in endocrine medicine. Organized into seven chapters, this volume begins with an overview of the knowledge of the structure and other chemical aspects of the hormones. This text then examines the effects of growth hormone on nitrogen retention and body composition and discusses the metabolic basis for the nitrogen-retaining action of growth hormone. Other chapters consider the biochemical pathways of metabolism and their control in thyroid tissue. This book discusses as well tumor induction in endocrine organs following hormonal imbalance. The final chapter deals with the many and varied causes of the spontaneous endocrine disorders. This book is a valuable resource for organic chemists, biochemists, endocrinologists, morphologists, physiologists, students, and research workers.
