Download or read book Paleontology of the Upper Eocene Florissant Formation Colorado written by Herbert William Meyer and published by Geological Society of America. This book was released on 2008 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Florissant formation's fossil beds and petrified forest are interesting in themselves but also shed light on questions of paleoecology, macroevolution, and taphonomy (the study of the process of fossilization). Meyer (National Park Service. Florissant Fossil Beds National Monument, Colorado) and Smith (U. of Colorado Museum of Natural History--Paleontology/geological sciences, UC, Boulder) introduce 11 papers examining Florissant fossil flora, fauna, mineralogy and geochemistry through different periods and via a model of the role of microbial mats in its preservation. An integrated database/Web site to further related research is also discussed. The monograph is well-illustrated with geologic maps and images of historical figures in the field and specimens, but is not indexed.

Available in PDF, EPUB and Kindle. Book excerpt: Spiders are wonderful creatures. Their varied and complex range of behavior and highly developed sensory systems are excellently adapted to the environmental conditions - as is proven by their evolutionary success. Over 400 million years, spiders have developed their sensory organs to a fascinating technical perfection and complexity. In his intriguing book, Professor Friedrich G. Barth puts this technical perfection into the context of "biology", in which the interaction between environment and sensory organs and the selectivity of the senses as a link between environment and behavior play a major role.

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 Fossil Spiders written by David Penney and published by Siri Scientific Press. This book was released on 2011 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Spiders of Great Britain and Ireland Compact Edition written by Michael Roberts and published by BRILL. This book was released on 1993 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title has been out of print for some years, but has now been reprinted. It is now generally recognised as the definitive text on British spiders. Roberts' first edition of this work (3 vols, in 1987) superseded and updated the previous bible for British Arachnologists (Locket and Millidge, 1951, 1953 and 1974). This newer edition with additional Appendix, Addenda and Corrigenda in turn updates and revises the1987 edition. The first volume contains all the text, starting with a series of introductory notes on spider biology and some information on classification and nomenclature as it applies to spiders. Following this is a key to families and the species descriptions including 105 genera and 267 species of Linyphiidae. These two volumes are both a work of art and a work of science and so bring together the highest possible achievements of a human being. Their presence in the libraries of all academic as well as private Arachnid libraries is a must in order that their great value to the science of arachnology in Europe be allowed to bear fruit abundantly.

Download or read book Systematics conservation and morphology of the spider genus Tayshaneta Araneae Leptonetidae in Central Texas Caves written by Joel Ledford and published by PenSoft Publishers LTD. This book was released on 2012-01-23 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spider genus Tayshaneta is revised based on results from a three gene phylogenetic analysis (Ledford et al. 2011) and a comprehensive morphological survey using scanning electron (SEM) and compound light micros-copy. The morphology and relationships within Tayshaneta are discussed and five species-groups are supported by phylogenetic analyses: the anopica group, the coeca group, the myopica group, the microps group and the sandersi group. Short branch lengths within Tayshaneta contrast sharply with the remaining North American genera and are viewed as evidence for a relatively recent radiation of species. Variation in troglomorphic morphology is discussed and compared to patterns found in other Texas cave invertebrates. Several species previously known as single cave endemics have wider ranges than expected, suggesting that some caves are not isolated habitats but instead form part of interconnected karst networks. Distribution maps are compared with karst faunal regions (KFR?s) in Central Texas and the implications for the conservation and recovery of Tayshaneta species are discussed. Ten new species are described: T. archambaulti sp. n., T. emeraldae sp. n., T. fawcetti sp. n., T. grubbsi sp. n., T. madla sp. n., T. oconnorae sp. n., T. sandersi sp. n., T. sprousei sp. n., T. vidrio sp. n. and T. whitei sp. n. The males for three species, T. anopica (Gertsch, 1974), T. devia (Gertsch, 1974) and T. microps (Gertsch, 1974) are described for the first time. Tayshaneta furtiva (Gertsch, 1974) and T. uvaldea (Gertsch, 1974) are declared nomina dubia as the female holotypes are not diagnosable and efforts to locate specimens at the type localities were unsuccessful. All Tayshaneta species are thoroughly illustrated, diagnosed and keyed. Distribution maps are also provided highlighting areas of taxonomic ambiguity in need of additional sampling.
