Book Description
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.
Crayfishes of Alabama

Book Description
"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"--
