This book was released on 2014-01-28 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.

Download or read book Field Guide to South African Spiders written by Ansie Dippenaar-Schoeman and published by Penguin Random House South Africa. This book was released on 2014-02-20 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first-ever field guide to provide information on a vast spectrum of spider species based on their morphology, behaviour and distribution. It’s the first book to introduce all 70 South African spider families including 370 major genera and more than 860 of the more common species. It includes illustrations of all of the families, genera and species as well as more than 2 000 colour photographs and 843 maps. - A thorough summary of morphology, biology and habitat requirements is provided - Species with medical importance are discussed - The morphological characters of all known spider families from South Africa are provided and illustrated with notes on their behavior as well as further reading material - Short morphological data with notes on behaviour and distribution of 370 major genera and 860 species is provided This field guide’s purpose is to enable observers to identify spiders in the field. One of the difficulties facing a spider-watcher is that a large number of spider species are small and extremely well camouflaged and are therefore not easily seen. For some genera you will need a magnifying glass or microscope to be able to identify the specimen to generic or species level. Many species can only be identified by a specialist who has access to a good microscope and the relevant literature. Most of the spiders were photographed alive in their natural settings and only some rare and smaller species were photographed using a camera mounted on a microscope. The illustrations and descriptions make it easy for an inexperienced spider-watcher to identify many of the common species encountered in and around the house. The spiders were divided according to the free-living species and those that build intricate webs to catch their prey. The free-living spiders were further divided according to those found on the vegetation and those living on the ground. Spiders are an abundant, diverse and highly successful group of animals. They are commonly found on farms, in gardens and also in houses. They are important predators in all terrestrial ecosystems and are regarded as the “best friends” of gardeners and farmers in sustainable agriculture because they have the important task of regulating the numbers of potentially harmful insects and mites. However, they are feared and maligned because of the venom they produce. We hope this field guide will help save the lives of a few spiders. It will be valuable for the man on the street, researchers, conservation agencies, students, gardeners, farmers, as well as spider-watchers and photographers.

Download or read book Revision and Phylogenetic Analysis of the Spider Genus Philisca Simon Araneae Anyphaenidae Amaurobioidinae written by Eduardo M. Soto and published by . This book was released on 2012 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: We review the spider genus Philisca Simon, an endemic of the southern forests in Chile and Argentina, and present a phylogenetic analysis including 15 species, of which five are newly described (P. atrata, P. robinson, P. viernes, P. pizarroi and P. robusta), together with other 98 representatives of the family Anyphaenidae. Four species names are considered nomina dubia (Clubiona gayi Nicolet, Drassus mirandus Nicolet, Clubiona altiformis Nicolet, P. obscura Simon). Cluilius chilensis Mello-Leitão is newly synonymized with P. accentifera Simon. The phylogenetic analysis resulted in P. puconensis Ramírez branching off basally in the genus, because of its numerous leg spines and unmodified male chelicerae, all plesiomorphic for the group; the remaining species form two clear groups. The first one, formed by P. hahni Simon, P. tripunctata (Nicolet), P. amoena (Simon), P. hyadesi (Simon) and P. doilu (Ramírez), are grouped by the loss of spines on legs I and II. The second, formed by P. huapi Ramírez, P. ingens Berland, P. ornata Berland, P. accentifera Simon, P. atrata and four new species endemic to the Robinson Crusoe Island in the Juan Fernández Archipelago, have the male chelicerae, and in most cases also the endites, modified. In total, six species of Philisca are endemic to Juan Fernández, but our dataset is not conclusive for the distinction of alternative colonization scenarios. We analyze the evolution of leg macrosetae, and show two independent instances of reduction of spination, one on the continent and another on the Juan Fernández islands.

Download or read book A World in One Cubic Foot written by David Liittschwager and published by University of Chicago Press. This book was released on 2012-11-21 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twelve inches by twelve inches by twelve inches, the cubic foot is a relatively tiny unit of measure compared to the whole world. With every step, we disturb and move through cubic foot after cubic foot. But behold the cubic foot in nature—from coral reefs to cloud forests to tidal pools—even in that finite space you can see the multitude of creatures that make up a vibrant ecosystem. For A World in One Cubic Foot, esteemed nature photographer David Liittschwager took a bright green metal cube—measuring precisely one cubic foot—and set it in various ecosystems around the world, from Costa Rica to Central Park. Working with local scientists, he measured what moved through that small space in a period of twenty-four hours. He then photographed the cube’s setting and the plant, animal, and insect life inside it—anything visible to the naked eye. The result is a stunning portrait of the amazing diversity that can be found in ecosystems around the globe. Many organisms captured in Liittschwager’s photographs have rarely, if ever, been presented in their full splendor to the general reader, and the singular beauty of these images evocatively conveys the richness of life around us and the essential need for its conservation. The breathtaking images are accompanied by equally engaging essays that speak to both the landscapes and the worlds contained within them, from distinguished contributors such as Elizabeth Kolbert and Alan Huffman, in addition to an introduction by E. O. Wilson. After encountering this book, you will never look at the tiniest sliver of your own backyard or neighborhood park the same way; instead, you will be stunned by the unexpected variety of species found in an area so small. A World in One Cubic Foot puts the world accessibly in our hands and allows us to behold the magic of an ecosystem in miniature. Liittschwager’s awe-inspiring photographs take us to places both familiar and exotic and instill new awareness of the life that abounds all around.
