The Californian Floristic Province, located on the Pacific Coast of North America, is a region recognized as a ?biodiversity hotspot?.ÿ The area?s rich floristic diversity is also reflected in its remarkable diversity of mygalomorph spiders ? the group that includes trapdoor spiders, tarantulas, funnel spiders, and their other close relatives.ÿ This monograph documents the species diversity currently attributed to the euctenizid genus Aptostichus Simon distributed primarily throughout California, but also found in the habitats of Arizona and Nevada.ÿ Based on the examination of approximately 2000 specimens from museum and field collections, 40 species are assessed, 33 of which are new to science ?

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.

Latin names – frequently unpronounceable, all too often wrong and always a tiny puzzle to unravel – have been annoying the layman since they first became formalised as scientific terms in the eighteenth century. Why on earth has the entirely land-loving Eastern Mole been named Scalopus aquaticus, or the Oxford Ragwort been called Senecio squalidus – 'dirty old man'? What were naturalists thinking when they called a beetle Agra katewinsletae, a genus of fish Batman, and a Trilobite Han solo? Why is zoology replete with names such as Chloris chloris chloris (the greenfinch), and Gorilla gorilla gorilla (a species of, well gorilla)? The Naming of the Shrew will unveil these mysteries, exploring the history, celebrating their poetic nature and revealing how naturalists sometimes get things so terribly wrong. With wonderfully witty style and captivating narrative, this book will make you see Latin names in a whole new light.

The Theraphosidae are the most famous and diverse mygalomorph spiders, and include some of the largest arachnids on earth. Their unique defense mechanisms, predatory tactics, reproductive strategies and ecological adaptations are displayed by a wide range of terrestrial, burrowing and arboreal species. These arachnids are familiar to the general public thanks to horror movies and a growing interest in tarantulas as pets; however, scientific information on the group is scattered throughout the literature and not easily available. This book reviews all major aspects of New World Theraphosid tarantulas and provides in-depth information on their evolution, taxonomy, behavior, physiology, ecology, reproduction, conservation and biogeography. As a comprehensive guide to the biology of tarantulas, it will appeal to researchers, students and terrarium hobbyists alike.

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 is spurious and in need of reassessment. Secondly, to discuss the techniques available for working with fossil spiders and some of the problems encountered by palaeoarachnologists, including bias and limitations of the spider fossil record. Thirdly, the overall evolutionary history of spiders is summarized in the form of an evolutionary tree, which is subsequently used to address key issues of broad interest, such as origins, diversifications and extinctions, including the effects of mass extinctions and predator-prey co-radiations. Finally, the contribution that fossil data can make to understanding the past and present biogeography of the order is considered. This book should be of interest to both amateur and professional arachnologists and palaeontologists and will also serve as a general palaeontological reference work for neonologists studying extant spiders.

The book includes collection of theoretical papers dealing with the species problem, which is among most fundamental issues in biology. The principal topics are: consideration of the species problem from the standpoint of modern non-classical science paradigm, with emphasis on its conceptual status presuming its analysis within certain conceptual framework; evolutionary emergence of the species as discrete unit of certain level of generality; epistemological consideration of the species as a particular explanatory hypotheses, with respective revised concepts of biodiversity and conservation; considerations of evolutionary and phylogenomic species concepts as candidates for the universal one; re-appraisal of the biological species concept based on the "friend-foe" recognition system; species delimitation approach using multi-locus coalescent-based method; a re-consideration of the Darwin's species concept.

Spiders are among the most diverse groups of terrestrial invertebrates, yet they are among the least studied and understood. This first comprehensive guide to all 68 spider families in North America beautifully illustrates 469 of the most commonly encountered species. Group keys enable identification by web type and other observable details, and species descriptions include identification tips, typical habitat, geographic distribution, and behavioral notes. A concise illustrated introduction to spider biology and anatomy explains spider relationships. This book is a critical resource for curious naturalists who want to understand this ubiquitous and ecologically critical component of our biosphere.
