Available in PDF, EPUB and Kindle. Book excerpt: Reading the Shape of Nature vividly recounts the turbulent early history of the Museum of Comparative Zoology at Harvard and the contrasting careers of its founder Louis Agassiz and his son Alexander. Through the story of this institution and the individuals who formed it, Mary P. Winsor explores the conflicting forces that shaped systematics in the second half of the nineteenth century. Debates over the philosophical foundations of classification, details of taxonomic research, the young institution's financial struggles, and the personalities of the men most deeply involved are all brought to life. In 1859, Louis Agassiz established the Museum of Comparative Zoology to house research on the ideal types that he believed were embodied in all living forms. Agassiz's vision arose from his insistence that the order inherent in the diversity of life reflected divine creation, not organic evolution. But the mortar of the new museum had scarcely dried when Darwin's Origin was published. By Louis Agassiz's death in 1873, even his former students, including his son Alexander, had defected to the evolutionist camp. Alexander, a self-made millionaire, succeeded his father as director and introduced a significantly different agenda for the museum. To trace Louis and Alexander's arguments and the style of science they established at the museum, Winsor uses many fascinating examples that even zoologists may find unfamiliar. The locus of all this activity, the museum building itself, tells its own story through a wonderful series of archival photographs.
Download or read book Zoogeography Taxonomy and Conservation of West Virginia s Ohio River Floodplain Crayfishes Decapoda Cambaridae written by Zachary J. Loughman and published by PenSoft Publishers LTD. This book was released on 2011-01-06 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crayfish fauna of West Virginia consists of 23 species and several undescribed taxa. Most survey efforts documenting this fauna have been conducted in lotic waterways throughout the Appalachian plateau, Allegheny Mountains, and Ridge and Valley physiographic provinces. Bottomland forests, swamps, and marshes associated with large river floodplains such as the Ohio River floodplain historically have been under-surveyed, though these habitats harbor the richest primary burrowing crayfish fauna in West Virginia. The crayfish fauna of West Virginia?s Ohio River floodplain was surveyed from 2004 through 2009.ÿ From this survey, nine species from four genera were documented inhabiting the floodplain. Zoogeography, biology, and conservation status is provided for the nine species encountered in the survey, as well as a review of crayfish collection methods and a dichotomous key to West Virginia Ohio River floodplain crayfish species.

Download or read book Freshwater Crayfish Aquaculture in North America Europe and Australia written by Jay Huner and published by CRC Press. This book was released on 1994-04-25 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Crayfish Aquaculture in North America, Europe, and Australia is the first text to summarize the methods of culture for the eight most important crayfish species in the world. Methods developed to culture crayfishes around the world differ significantly, and this book enables readers to develop workable strategies for cultivating different crayfish species in specific environments. Huner and associate authors cover the following topics in detail: methods of crayfish culture crayfish diseases crayfish processing economics of crayfish culture Each of the the three major crayfish industries are well-represented in this new book and special attention is given to the specific needs and accomplishments of each area, which is beneficial to producers in other countries. For example, while hatching technology has been important in Australia and Europe, it hasn?t yet been applied to any degree in North America. At the same time, North America has developed a major crayfish processing industry. Disease problems have resulted in more emphasis on that subject in Europe and yet it is vital to all involved in crayfish aquaculture. Businessmen, farmers, scientists, laymen, or students need to be exposed to the methods and problems associated with crayfish production in different parts of the world if they are to be successful in any crayfish project, whether it be research- or profit-oriented. Freshwater Crayfish Aquaculture in North America, Europe, and Australia is intended to provide all readers with one source of information on the subject of freshwater crayfish aquaculture. Professional staff, advanced students, and extension personnel will find the entire text beneficial. Those in corporate organizations and the agriculture field, especially decisionmakersin operations, will find the methods, markets, and financial considerations in this book a helpful guide.

Download or read book Crayfishes of Alabama written by Guenter A. Schuster and published by University of Alabama Press. This book was released on 2022-04-19 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book represents the most in-depth treatment of crayfishes for the state of Alabama to date. Alabama is currently known to host 99 species of crayfishes. The findings in this book are based on more than 9,000 records gathered from across the entire state. The authors collected specimens and data from all of Alabama's major and minor waterways and lakes, as well as specialized habitats such as burrows, roadside ditches, marshes, swamps, and temporary autumnal ponds. They visited all the major museums with holdings of crayfish specimens from Alabama, yielding a list of historical records including 4,259 specimen lots from approximately 2,200 unique locations. These records were used to build a database containing all available specimen metadata, including, but not limited to: species identification, number of individuals collected, location, date of collection, names of collectors, who identified the specimens, and the museum in which they are stored. Field work was conducted over a 14-year period during which a total of 4,487 specimen lots were collected and added to the database from approximately 2,600 unique locations sampled across Alabama. Prior to this book, no single comprehensive book or reference has ever been published on the crayfishes of Alabama. This book compiles 166 years of crayfish distributional and biological data for the 99 known Alabama species. It begins with chapters on the physiography and waterways of Alabama. One chapter discusses the general distributional patterns and habitat associations of Alabama crayfishes. Subsequent chapters discuss crayfish biology, ecology, conservation, and anatomy. Detailed species accounts include descriptions of morphological characters, life color, maximum size, comparative species, distribution and habitat, biology, crayfish associates, and conservation status. Color photographs, morphological plates, and dot maps showing distributions are included for each species; for many species, multiple color photos demonstrate the known color variations within each species. An illustrated key is provided to guide the identification of all 99 species. As the most up-to-date and comprehensive source of information on Alabama crayfishes to date, "Crayfishes of Alabama" provides a new perspective on Alabama's unique place as a biodiversity hotspot. It will be of lasting value to aquatic biologists and ecologists throughout the Southeast and crayfish biologists around the world, as well as of interest to natural resource managers, aquaculture farmers, and naturalists"--
Download or read book Crustaceans and the Biodiversity Crisis written by Frederick R. Schram and published by BRILL. This book was released on 2023-07-03 with total page 1033 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important and extensive volume presents part of the Proceedings of the Fourth International Crustacean Congress held in Amsterdam in 1998. As the title implies, 'Crustaceans and the Biodiversity Crisis' was the general, underlying theme of all contributions at the congress. With the turn of the century, someone ought to 'assess the balance' of our natural environment and of the various branches of biology that study its rapidly declining diversity. From the five subthemes covered at the conference, those of (1) Diversity in Time and Space (including Systematics, Phylogeny, and Palaeontology), (2b) Biogeography, (3c) Larvae, and (4) Physiology and Biochemistry (including Molecular Biology and Genetics) are represented in this volume, along with a few contributions from other subthemes (e.g. (2a) Invasive Crustacea, (3a) Ecology, (3b) Behaviour, and (5) Fisheries and Aquaculture). The book is primarily meant for scientists working at institutes involved in research on the group (Crustacea: marine, freshwater, or terrestrial) and/or the disciplines covered. Individual carcinologists working on one of the themes discussed in this volume, will find a wealth of interesting and timely contributions, as will other scientists working in marine or freshwater biology or in soil ecology.

Download or read book Crawfishes of Louisiana written by Jerry G. Walls and published by LSU Press. This book was released on 2009-04-01 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everyone in Louisiana knows something about crawfish -- especially how tasty they can be when boiled with just the right combination of spices. Yet these small crustaceans -- known as "crayfishes" by scientists and "mudbugs" by many fishermen -- offer more than a delicious meal. In Crawfishes of Louisiana, Jerry G. Walls identifies the state's thirty-nine types of crawfishes, explains their biology, and explores their importance in Louisiana's history, culture, and economy. Walls briefly describes each species and subspecies of crawfish currently known to live in Louisiana, as well as their natural history and complicated breeding biology. Detailed illustrations depict pertinent taxonomic features, color photographs of living specimens aid in identification, and maps indicate species distribution throughout the state. Two identification keys further assist users in classifying any crawfish they encounter. Drawing on his experiences collecting crawfishes over the past fifty years, Walls explores changes in their populations and in the environmental health of their habitats. In the early part of the twentieth century, many Louisianans thought eating crawfish outside of Lent was an embarrassing admission of poverty. Now crawfish is a celebrated delicacy in restaurants and at festivals offering crawfish boils, crawfish races, crawfish cook-offs -- even the election of a crawfish queen and court. Crawfish provide recreational fishing opportunities in ditches and lakes across southern and central Louisiana, and commercial fishermen net roughly 70,000 tons of crawfish each year and process them in a fishery employing over 2,500 people. Walls offers insights into all of these areas along with cooking tips and recipes and, at the other extreme, instructions for keeping crawfish as pets. Crawfishes of Louisiana is an invaluable and enjoyable resource for all fans of this famous Louisiana crustacean.
