Book excerpt: Excerpt from A Revision of the Astacidae, Vol. 10: Part I. The Genera Cambarus and Astacus The following Revision of the crayfishes of the Northern hemisphere is based mainly upon the material in the Museum of Comparative Zoology. Through gifts from friends, and through a system of exchanges carried on during the past few years, the Museum now possesses all the known species of Astacus from Europe and Asia, together with all the American species of Astacus and Cambarus excepting Cambarus angustatiis (Le Conte), C.Wicgmanni Erichs., and C.Mexicanus Erichs., and the doubtful species C.mamcuMus (Le Conte), C.Stygius Bundy, C.Nebrascensis Girard, and Asiacus Orcgamis Randall. In this collection is included the chief part of the material used by Dr. Hagen in the preparation of his Monograph of the North American Astacida?, a work which forms the foundation of our knowledge of the crayfishes of this continent. One may form some notion of the importance of the material received since the publication of Hagens memoir, from the fact that twenty new species of Cambarus are made known in the following pages, while Dr. Hagen described but ten unknown to previous authors. Besides the collection in the Museum of Comparative Zoology, I have examined these: - 1.The collection in the United States National Museum at Washington. Next to that at Cambridge this is the richest collection of Astacidae in the United States, and both have been much benefited by interchanges. All of the new material received at the National Museum during the preparation of this Revision has been promptly sent to me for study.

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 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.
