Compared to insects, fossil spiders have received only scant attention in the literature. Previously, the only works available were numerous scientific papers, many published in foreign languages. Most of these are basic descriptive taxonomic works, with very few considering broader biological concepts. Despite a significant increase in the discovery and description of fossil spiders within the last quarter Century this void remained unfilled. Thus, this short monograph aims to achieve several objectives. Firstly, to provide general and up to date background information on the overall importance and diversity of fossils spiders, including an indication of those groups for which the taxonomy ...
For many in the nineteenth century, the spoken word had a vivacity and power that exceeded other modes of communication. This conviction helped to sustain a diverse and dynamic lecture culture that provided a crucial vehicle for shaping and contesting cultural norms and beliefs. As science increasingly became part of public culture and debate, its spokespersons recognized the need to harness the presumed power of public speech to recommend the moral relevance of scientific ideas and attitudes. With this wider context in mind, The Voice of Science explores the efforts of five celebrity British scientists—John Tyndall, Thomas Henry Huxley, Richard Proctor, Alfred Russel Wallace, and Henry Dr...
Fossil arachnids date back more than 400 million years to the Silurian period, making them one of the first animal groups to appear in terrestrial ecosystems. This book provides information on what the arachnids are and their relationships to one another.
This special edition of ZooKeys contains papers on systematics presented at the 15th International Congress of Myriapodology held in Brisbane, Australia, 18?22 July 2011. Non-systematics papers from the congress are beingÿ published concurrently in International Journal of Myriapodology volume 6. The International Congress of Myriapodology is held every three years under the auspices of the Centre International de Myriapodologie.
With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.
For many people, long-legged spiders, blood-sucking ticks and venomous scorpions are the stuff of nightmares, but to others they are a source of constant fascination. Arachnids dispels common myths and misconceptions to reveal the truth about these weird, wonderful and often beautiful creatures. The class of Arachnida does not consist of spiders alone but also contains ten other orders a harvestmen, ticks and mites, wind spiders, tailless whip spiders, whip spiders, scorpions, palpigrades, pseudoscorpions, schizomids and ricinuleids a nearly all of which have eight legs and two parts to their body. Discover the ritual 'dance' of scorpion courtship, the mite species which can be found living in monkey lungs, and the thoughtful spider that actually regurgitates food to feed its young.
