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.

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 Thorp and Covich s Freshwater Invertebrates written by James H. Thorp and published by Elsevier. This book was released on 2014-09-06 with total page 1149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich’s Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. Global coverage of aquatic invertebrate ecology Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group Separate chapters on invasive species and economic impacts and uses of invertebrates Eight additional chapters on insect orders and a chapter on freshwater millipedes Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series Identification keys to lower taxonomic levels

Download or read book Reading the Shape of Nature written by Mary P. Winsor and published by University of Chicago Press. This book was released on 2011-05-04 with total page 345 pages. 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.
