Download or read book The velvet spiders an atlas of the Eresidae Arachnida Araneae written by Jeremy A. Miller and published by PenSoft Publishers LTD. This book was released on 2012-05-18 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The name velvet spider describes the dark and shiny appearance of members of the family Eresidae. Some species also have brightly-colored highlights, such as the red, white, and black ladybird spiders of Europe and North Asia. This family also includes some of the world?s most cooperative spider species. Social species can be very abundant in parts of tropical Africa and Asia with conspicuous colonies dotting the landscape. Social colonies may consist of hundreds of closely-related individuals that participate in dramatic mass attacks on prey and care for their young. The ecology of these social species is fascinating and has been the subject of several landmark scientific papers. By contrast, most kinds of velvet spider are rarely encountered. Most species keep well hidden or dig burrows and live underground. This monograph provides a generic-level review of Eresidae documented with collections of photographs, scanning electron micrographs, and illustrations. A key to the nine genera and other major lineages is provided. A new phylogeny of Eresidae based on molecular sequence data expands on a previously published analysis. Cybertaxonomic enhancements include an interactive map of the specimens used in the study explorable using Google Earth, specimen records uploaded to GBIF, and molecular sequence alignments and other data archived on Dryad. An EDIT Integrated Research grant provided principal funding for this project.

Download or read book All You Need to Know About Spiders written by Wolfgang Nentwig and published by Springer Nature. This book was released on 2022-04-07 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: All You Need to Know About Spiders Spiders are super predators and devour everything they can overpower. To do this, they have developed incredibly good catching techniques and, with spider silk, a tool that makes material technology green with envy. The males are usually smaller than the females and, in order to have sex, they have to come up with a lot to avoid being misunderstood as easy prey: Dancing, drumming, and gifts almost always help. Spiders use their venom in very precise doses, and since humans are not on their menu, they are harmless to us. Many people's (unnecessary) fear of spiders finds cultural roots as early as the Middle Ages. Nevertheless, spider fear is easily treatable. There is no habitat or building without spiders. And that's a good thing, because spiders have fascinating properties and their world is full of surprises. Everything you need to know about them is explained in this book in understandable language by experts for laymen. In addition, some of the most common spider species in the house and garden are briefly presented with tips for observation. The authorsThis book is authored by eight scientists, all of them members of the Association for the Promotion of Spider Research: Wolfgang Nentwig, Jutta Ansorg, Angelo Bolzern, Holger Frick, Anne-Sarah Ganske, Ambros Hänggi, Christin Kropf und Anna Stäubli
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 The Lives of Spiders written by Ximena Nelson and published by Princeton University Press. This book was released on 2024-06-04 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: A beautifully illustrated guide to the natural history and breathtaking diversity of spiders around the world Spiders are dominant predators in virtually every terrestrial ecosystem on the planet. A marvel of evolution with species numbering in the tens of thousands, they have been walking the earth since before the dinosaurs. Spiders manipulate the silk strands of their webs to act as a sensory field, which vibrates across wide frequencies that they can read in detail, while young spiders spin silk lines that interact with the electrical fields in the atmosphere, enabling them to balloon across huge distances. Some spiders even gather in groups to impersonate ants in astonishing displays of collective mimicry. The Lives of Spiders explores these and other wonders, blending stunning imagery, lively writing, and the latest science to explore the natural history of the world's diverse arachnid life. Features a wealth of color illustrations Sheds invaluable light on the life history, ecology, and stunning diversity of spiders Covers silk and web building, venoms, predators and prey, mating and dancing, spider cognition, and much more Discusses the impacts of human activity on spiders

Download or read book Consider the Platypus written by Maggie Ryan Sandford and published by Black Dog & Leventhal. This book was released on 2019-08-27 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: *FINALIST FOR THE 2020 GENERAL NONFICTION MINNESOTA BOOK AWARDS* Interested in the origins of the species? Consider the Platypus uses pets such as dogs and cats as well as animal outliers like the axolotl and naked mole rat to wittily tackle mind-bending concepts about how evolution, biology, and genetics work. Consider the Platypus explores the history and features of more than 50 animals to provide insight into our current understanding of evolution. Using Darwin's theory as a springboard, Maggie Ryan Sandford details scientists' initial understanding of the development of creatures and how that has expanded in the wake of genetic sequencing, including the: Peppered Moth, which changed color based on the amount of soot in the London air; California Two-Spotted Octopus, which has the amazing ability to alter its DNA/RNA not over generations but during its lifetime; miniscule tardigrade, which is so hearty it can withstand radiation, lack of water and oxygen, and temperatures as low as -328°F and as high 304 °F; and, of course, the platypus, which has so many disparate features, from a duck's bill to venomous spur to mammary patches, that scientists originally thought it was a hoax. Surprising, witty, and impeccably researched, Sandford describes each animal's significant features and how these have adapted to its environment, such as the zebra finch's beak shape, which was observed by Charles Darwin and is a cornerstone of his Theory of Evolution. With scientifically accurate but charming art by Rodica Prato, Consider the Platypus showcases species as diverse as the sloth, honey bee, cow, brown kiwi, and lungfish, to name a few, to tackle intimidating concepts is a accessible way.

Book excerpt: Soil invertebrates make up diverse communities living in soil pores and on the soil surface, digging burrows and tunnels, processing organic matter and interacting with microbes. Soil is also a habitat of growing concern as many human activities cause soil degradation. This book documents the evolutionary history of soil invertebrates and their multitude of adaptations. Soil invertebrates live in a twilight zone: some have gone down to seek stability, constancy and rest, others have gone up and faced environmental variation, heat, cold and activity. And it all happens in a few decimetres, millimetres sometimes. Check out the wonderful life below ground in this book.
