Book Description
Systematics, geographic variation, and postglacial dispersal patterns are examined in Hybognathus hankinsoni (brassy minnow) and Couesius £l u mbe us (lake chub)• Morphological differences between Missouri River basin and Great Lakes basin H. ha n k ins oni were discovered. Northern Alberta and British Columbia populations most closely resemble those from the Great Lakes region. It is postulated that the Missouri form originated in 'he "Preglacial Plains Stream" and survived glaciation in the Missouri basin. The form presently found in the Great Lakes region most likely originated in the pre-Pleistocene Laurentian River system and/or Missouri River system and survived glaciation in the upper Mississippi basin. Dispersal into northern Alberta and British Columbia was probably via Campbell phase Lake Agassiz and glacial Lake Peace. Taxonomic recognition of the two forms does not seem warranted. Existence of three morphological forms of C. plumbeus is confirmed - an upper Columbia River basin "greeni", a Missouri basin "dissimilis", and an eastern and Great Lakes "plumbeus". All three forms intergrade extensively throughout the northwest portion of the geographic range, while in the Lake Superior region "dissimilis" and "plumbeus" seem to be good biological species. Morphological differences between the "dissimilis" and "pluabeus" forms appear related to ecological differences. The "greeni 1 ' form most likely originated in the Columbia River basin, while the "dissimilis" form probably originated in the Missouri River basin. The "plumbeus" form may have originated in the pre-Pleistocene Laurentian River system and survived glaciation in an eastern lower Great Lakes refugium. Phenetic and cladistic analyses suggest that the genus Couesius is most closely related to the nominal genus Margari neus and it is suggested that they be combined into a single genus, Couesius. Proposals to unite Couesius with Hy bopsis or Sesotilus are not supported. Evidence indicating possible hybridization between Couesius olu mbe us and Semotilus (Xargariscus) sarcrarita is presented.

Book Description
The Cyprinidae is one of the two largest families of vertebrates in the world. This book draws together the experience of more than 30 international experts to provide the first comprehensive account of the biology of this family. The book is divided broadly into three sections. First, the origins and present day geographical distributions of these fishes are discussed in the light of recent research. This is followed by detailed accounts of cyprinid biology, in terms of feeding, physiology, reproduction and behaviour. The final chapters of the book cover the cyprinids' considerable applied importance with respect to environmental management, fisheries and aquaculture. As this family is extremely important as forage fish for other animals, as food fish for humans and are commonly used as models in experimental work, the book will be of great interest to all those with an interest in freshwater fish, fish ecology, fisheries biology and aquaculture systems.

Book Description
In 'Geographic Variation in the North American Cyprinid Fish, Hybopsis gracilis,' editors Leonard J. Olund and Frank B. Cross compile a comprehensive anthology that delves into the diverse biological adaptations and geographic distributions of Hybopsis gracilis. This collection not only showcases a range of scientific methodologies and theories but also places the species within the broader context of North American freshwater biodiversity. The anthology stands out for its detailed comparative analyses, committing to a holistic understanding of the species' ecological niche and evolutionary trajectory. The contributions within offer a cogent reminder of the complexity and beauty of nature's designs, vividly encapsulating the variance across climates and habitats without leaning excessively on any single narrative or hypothesis. The backgrounds of Olund and Cross, along with their selected contributing authors, encompass a rich tapestry of expertise in ichthyology, ecology, and evolutionary biology. Their collective work aligns with current conservation priorities and offers essential insights into the adaptive strategies of freshwater fish. This unification of perspectives does more than highlight individual accomplishments; it underscores the value of collaborative research in addressing broader ecological questions. Within this anthology lies an invitation to both the scholarly community and enthusiasts of natural sciences to explore the nuanced interactions between species and their environments. Fostering a deeper appreciation for geographic variation, this volume promises not only to educate but to inspire further inquiry into the biodiversity that underpins our world.

Book Description
The threat of deteriorating habitats and a loss of biodiversity make this reference work on the freshwater fishes of British Columbia more necessary than ever before. Eighty-one comprehensive species accounts aid accurate identification and consist of an illustration, the scientific and common names of the fish, its distinguishing characteristics, taxonomic comments, geographic distribution, a life-history summary, a habitat-use summary, and conservation comments. The book is a critical resource for biologists, naturalists, management and conservation officers, anglers, and members of the public who are concerned about our natural heritage.

Book Description
Among the fishes. a remarkably wide range ofbiological adaptations to diverse habitats has evolved. As weIl as living in the conventional habitats of lakes. ponds. rivers. rock pools and the open sea. fish have solved the problems of life in deserts. in the deep sea. in the cold Antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations. we find the most impressive specializations of morphology. physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas. air breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover. fish are of considerable importance of the survival of the human species in the form ofnutritious and delicious food ofnumerous kinds. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology. but an additional aim is for the books to be accessible to a wide spectrum of non specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

Now Fishes of Oklahoma, the only comprehensive handbook available for identifying fishes across the state of Oklahoma, is available to scientists and to anglers interested in knowing more about the fish they catch. Precise keys and clear black-and-white photos or drawings of every species allow for the ready identification of all Oklahoma fishes. Within each species account is a map showing where the fish can be found in the state, as well as information on its habitat and biology. Also included is a color section showcasing brilliant paintings by Rudolph J. Miller. Noteworthy features: • Common and scientific names • Black-and-white photos or drawings of each species • Detailed descriptions of each species • Distribution maps of each species • Habitat and biology information • Recent research on endangered species • Glossary of terms • Color paintings of many species
