Available in PDF, EPUB and Kindle. Book excerpt: T. J. MABRY and G. W AGENITZ The half-day symposium on "Multidisciplinary approaches to the systematics of Compositae", held as part of the XIV International Botanical Congress in Berlin, on July 26, 1987, was designed to complement the University of Reading Compositae Conference (1975). The latter had yielded two impressive and thorough volumes on "The biology and chemistry of the Compositae", which were edited by HEYWOOD, HARBORNE & TURNER (1977). The 1987 Berlin Symposium did not attempt to update the information from the earlier conference but instead focussed on selected new methods for investigating the systematics of the family as well as a few examples of new systematic approaches with classical methods. From mapping chloroplast DNA restriction sites JANSEN, PALMER, and MI CHAELS reported the astonishing fact that, with the exception of one group (the subtribe Barnadesiinae of the tribe Mutisieae), all investigated other members of Compositae exhibit a characteristic inversion in their chloroplast DNA, suggesting that the inversion occurred early in the evolution of the family and that at least its major part is monophyletic. Within those groups with the inverted segment, chloroplast DNA also suggests that most of the conventionally recognized tribes are also monophyletic. This lends high credit to our predecessors who laid the foundations for the taxonomic system of the Compositae. These chloroplast DNA studies have already been published and are not included here (JANSEN & PALMER 1987, 1988).

Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Study Institute on Numerical Taxonomy took place on the 4th - 16th of July, 1982, at the Kur- und Kongresshotel Residenz in Bad Windsheim, Federal Republic of Germany. This volume is the proceedings of that meeting, and contains papers by over two-thirds of the participants in the Institute. Numerical taxonomy has been attracting increased attention from systematists and evolutionary biologists. It is an area which has been marked by debate and conflict, sometimes bitter. Happily, this meeting took place in an atmosphere of "GemUtlichkeit", though scarcely of unanimity. I believe that these papers will show that there is an increased understanding by each taxonomic school of each others' positions. This augurs a period in which the debates become more concrete and specific. Let us hope that they take place in a scientific atmosphere which has occasionally been lacking in the past. Since the order of presentation of papers in the meeting was affected by time constraints, I have taken the liberty of rearranging them into a more coherent subject ordering. The first group of papers, taken from the opening and closing days of the meeting, debate philosophies of classification. The next two sections have papers on congruence, clustering and ordination. A notable concern of these participants is the comparison and testing of classifications. This has been missing from many previous discussions of numerical classification.
Download or read book Biological Metaphor and Cladistic Classification written by Henry M. Hoenigswald and published by University of Pennsylvania Press. This book was released on 2016-11-11 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamic aspect of biological systems—the birth, growth, and death of individual organisms, the evolution of one form into another over time—has formed the basis for metaphors used in many fields for both artistic and heuristic purposes. Cladistic classification uses a tree whose branch points are based on the possession of derived or relatively recent characteristics, rather than primitive ones.

Download or read book Phylogeny Ecology and Behavior written by Daniel R. Brooks and published by University of Chicago Press. This book was released on 1991 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The merits of this work are many. A rigorous integration of phylogenetic hypotheses into studies of adaptation, adaptive radiation, and coevolution is absolutely necessary and can change dramatically our collective 'gestalt' about much in evolutionary biology. The authors advance and illustrate this thesis beautifully. The writing is often lucid, the examples are plentiful and diverse, and the juxtaposition of examples from different biological systems argues forcefully for the validity of the thesis. Many new insights are offered here, and the work is usually accessible to both the practiced phylogeneticist and the naive ecologist."—Joseph Travis, Florida State University "[Phylogeny, Ecology, and Behavior] presents its arguments forcefully and cogently, with ample . . .support. Brooks and McLennan conclude as they began, with the comment that evolution is a result, not a process, and that it is the result of an interaction of a variety of processes, environmental and historical. Evolutionary explanations must consider all these components, else they are incomplete. As Darwin's explanations of descent with modification integrated genealogical and ecological information, so must workers now incorporate historical and nonhistorical, and biological and nonbiological, processes in their evolutionary perspective."—Marvalee H. Wake, Bioscience "This book is well-written and thought-provoking, and should be read by those of us who do not routinely turn to phylogenetic analysis when investigating adaptation, evolutionary ecology and co-evolution."—Mark R. MacNair, Journal of Natural History

Download or read book The Major Metaphors of Evolution written by Salvatore J. Agosta and published by Springer Nature. This book was released on 2020-08-29 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a unified evolutionary framework based on three sets of metaphors that will help to consolidate discussions on evolutionary transitions. Evolution is the unifying principle of life, making identifying ways to apply evolutionary principles to tackle existence-threatening crises such as climate change crucial. A more cohesive evolutionary framework will further the discussions in this regard and also accelerate the process itself. This book lays out a framework based on three dualistic classes of metaphors – time, space, and conflict resolution. Evolutionary transitions theory shows how metaphors can help us understand selective diversification, as Darwin described with his “tree of life”. Moreover, the recently proposed Stockholm paradigm demonstrates how metaphors can help shed light on the emergence of complex ecosystems that Darwin highlighted with his “tangled bank” metaphor. Taken together, these ideas offer proactive measures for coping with existential crises for humanity, such as climate change. The book will appeal to biologists, philosophers and historians alike.

Download or read book The Trees of Sonora Mexico written by Tucson Richard Stephen Felger Executive Director Drylands Institute, AZ and published by Oxford University Press, USA. This book was released on 2001-03-31 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive treatment of the trees and tree-like plants of Sonora, a remarkably diverse and biologically important region, ranging from some of the driest and hottest areas in North America to cool, temperate woodlands and the northernmost tropical regions in the New World. The majority of the trees in this semi-arid region are at their northern limits in the Americas in this state and many range to South America. Thus, this book will be important to biologists in regions well outside of the area covered. Felger is the recognized expert in the area, and the book contains an enormous body of information nowhere else obtainable. The introductory chapter contains biotic and climatic information and an analysis of the geographical distributions of the trees of a state that is poorly known biologically. Two hundred eighty-five species of native and naturalized trees are covered, featuring extensive identification keys and illustrations, most of them newly produced for this book. The descriptive species accounts include common names, indigenous names, and synonyms, detailed botanical descriptions, ecological and geographic data, geographic ranges, natural history, economic uses, and, in many cases, other information such as horticultural uses and conservation status.

Available in PDF, EPUB and Kindle. Book excerpt: All living things on earth—from individual species to entire ecosystems—have evolved through time, and evolution is the acknowledged framework of modern biology. Yet many areas of biology have moved from a focus on evolution to much narrower perspectives. Daniel R. Brooks and Deborah A. McLennan argue that it is impossible to comprehend the nature of life on earth unless evolution—the history of organisms—is restored to a central position in research. They demonstrate how the phylogenetic approach can be integrated with ecological and behavioral studies to produce a richer and more complete picture of evolution. Clearly setting out the conceptual, methodological, and empirical foundations of their research program, Brooks and McLennan show how scientists can use it to unravel the evolutionary history of virtually any characteristic of any living thing, from behaviors to ecosystems. They illustrate and test their approach with examples drawn from a wide variety of species and habitats. The Nature of Diversity provides a powerful new tool for understanding, documenting, and preserving the world's biodiversity. It is an essential book for biologists working in evolution, ecology, behavior, conservation, and systematics. The argument in The Nature of Diversity greatly expands upon and refines the arguments made in the authors' previous book Phylogeny, Ecology, and Behavior.
Download or read book The Origin Expansion and Demise of Plant Species written by Donald A. Levin and published by Oxford University Press. This book was released on 2000-05-04 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining insights from observation, experimentation, and theory, The Origin, Expansion, and Demise of Plant Species offers a broad overview of species as dynamic entities that arise, have unique evolutionary histories, and ultimately go extinct. It begins with a review of species concepts and the exposition of a new concept; it then addresses plant speciation, the expansion of species from their narrow centers of origin, intraspecific differentiation, and contact zones between differentiated population systems. Special attention is given to the breakdown of cohesion among populations by reproductive and spatial barriers. Also, the ecological and genetic properties of small populations and fragmented population systems are discussed with a focus on the role of hybridization in the demise of species. It ends with an exploration of the longevity of species and the tempo of diversification, contrasting different groups of plants in these respects as well as in rates of chromosomal differentiation. This book provides a new synthesis of evolutionary biology and ecology. It examines species from their origins, then follows them through their expansion, differentiation and loss of cohesion, and decline and extinction. The stages in the lives of species are viewed through ecological and genetic theory, and topics typically addressed independently are woven into a continuous fabric. As the first synthetic treatment of the stages through which plant species pass, this book is very useful for botanists, evolutionary biologists, conservation biologists, as well as all curious students of the biological sciences.
