A system of classifying and coding entomological information from the world literature on arthropods which affect the health and comfort of man onto punch cards was developed to provide a method for readily recovering this information for immediate use. More than 700 journals and other scientific publications from which data for coding may be drawn are listed. Titles are arranged alphabetically nd are numbered for entry on punch cards, which also indicate the author and date of publication. A geographic code for the world listing major administrative subdivisions for most countries, indicates the geographical areas for recording entomological data on punch cards. A world map is inclosed to aid in the identification of the major geographic l entries. The classification for subject matter co ins 9 categories of information for which space is assigned on the cards. Included are designations for genus, species, geographical range, seasonal activity, breeding habitat, and disease relationships. (Author).

A stunning diversity of frog species can be found from coastal swamps to lofty mountain peaks, and from the Florida Keys to the Arctic Ocean. They live in subtropical lowlands, grassland prairies, deserts, and alpine-tundra habitats. Some species have restricted habitat requirements, whereas others occur contiguously from the arid plains or humid southeastern forests to the high tundra. In this new edition of Frogs of the United States and Canada, C. Kenneth Dodd Jr. tours the reader through the marvelous world of North American frogs. Covering 114 native and introduced species from all US states and Canadian provinces, this comprehensive reference on the biology, behavior, and conservation of the Order Anura includes detailed and updated information on • past and present distribution • life history and demography • reproduction and diet • landscape ecology and evolution • diseases, parasites, and threats from toxic substances • conservation and management Hundreds of occurrence maps, line drawings, and new color photographs of frogs and their habitats enhance the text. The most thorough treatment of the life histories, distribution, and status of North American frogs ever produced, Frogs of the United States and Canada has been the go-to reference for naturalists, scientists, and resource managers in their efforts to understand and conserve frogs, their habitats, and biodiversity for over a decade. Based on a meticulously updated examination of more than 8,000 references current through 2021, this second edition ensures Dodd's master work will remain an unparalleled resource for years to come.
