Download or read book The Timetree of Life written by S. Blair Hedges and published by OUP Oxford. This book was released on 2009-04-23 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary history of life includes two primary components: phylogeny and timescale. Phylogeny refers to the branching order (relationships) of species or other taxa within a group and is crucial for understanding the inheritance of traits and for erecting classifications. However, a timescale is equally important because it provides a way to compare phylogeny directly with the evolution of other organisms and with planetary history such as geology, climate, extraterrestrial impacts, and other features. The Timetree of Life is the first reference book to synthesize the wealth of information relating to the temporal component of phylogenetic trees. In the past, biologists have relied exclusively upon the fossil record to infer an evolutionary timescale. However, recent revolutionary advances in molecular biology have made it possible to not only estimate the relationships of many groups of organisms, but also to estimate their times of divergence with molecular clocks. The routine estimation and utilization of these so-called 'time-trees' could add exciting new dimensions to biology including enhanced opportunities to integrate large molecular data sets with fossil and biogeographic evidence (and thereby foster greater communication between molecular and traditional systematists). They could help estimate not only ancestral character states but also evolutionary rates in numerous categories of organismal phenotype; establish more reliable associations between causal historical processes and biological outcomes; develop a universally standardized scheme for biological classifications; and generally promote novel avenues of thought in many arenas of comparative evolutionary biology. This authoritative reference work brings together, for the first time, experts on all major groups of organisms to assemble a timetree of life. The result is a comprehensive resource on evolutionary history which will be an indispensable reference for scientists, educators, and students in the life sciences, earth sciences, and molecular biology. For each major group of organism, a representative is illustrated and a timetree of families and higher taxonomic groups is shown. Basic aspects of the evolutionary history of the group, the fossil record, and competing hypotheses of relationships are discussed. Details of the divergence times are presented for each node in the timetree, and primary literature references are included. The book is complemented by an online database (www.timetree.net) which allows researchers to both deposit and retrieve data.

Download or read book Spider Behaviour written by Marie Elisabeth Herberstein and published by Cambridge University Press. This book was released on 2011-01-27 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spiders are often underestimated as suitable behavioural models because of the general belief that due to their small brains their behaviour is innate and mostly invariable. Challenging this assumption, this fascinating book shows that rather than having a limited behavioural repertoire, spiders show surprising cognitive abilities, changing their behaviour to suit their situational needs. The team of authors unravels the considerable intra-specific as well as intra-individual variability and plasticity in different behaviours ranging from foraging and web building to communication and courtship. An introductory chapter on spider biology, systematics and evolution provides the reader with the necessary background information to understand the discussed behaviours and helps to place them into an evolutionary context. Highlighting an under-explored area of behaviour, this book will provide new ideas for behavioural researchers and students unfamiliar with spiders as well as a valuable resource for those already working in this intriguing field.

It brings together the dimensions of biodiversity and examines both the services it provides and the measures to protect it. Major themes of the work include the evolution of biodiversity, systems for classifying and defining biodiversity, ecological patterns and theories of biodiversity, and an assessment of contemporary patterns and trends in biodiversity. The science of biodiversity has become the science of our future. It is an interdisciplinary field spanning areas of both physical and life sciences. Our awareness of the loss of biodiversity has brought a long overdue appreciation of the magnitude of this loss and a determination to develop the tools to protect our future.

Book excerpt: This book, dedicated to the influential Danish spider ecologist Edwin Ngaard, contains contributions by authors from 16 European countries, and reflects the current areas of interest for researchers working with spiders, scorpions and related animals in Europe. It contains 46 original research articles and reviews covering a wide range of disciplines such as ecology and conservation, behavior, physiology, morphology and systematics. A particular section is devoted to reproductive behavior, with papers on sexual selection, sperm competition is relation to the structure of female genitalia, emasculation and sexual cannibalism in spiders, and parthenogenesis in scorpions. Silk and the structure and construction of spider webs form another section. There are papers on sampling methods and faunistic analyses of the biodiversity and conservation value of spider communities from several types of habitats (forests, dunes, bogs etc.) in various European countries. Other papers deal with the value of spiders for agriculture, prey capture strategies, spiders parasites, life cycles, neuronal mapping of reflex behavior, the systematic classification of spiders and local faunistics.
