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).
Download or read book Vascular Plants of Texas written by Stanley D. Jones and published by University of Texas Press. This book was released on 2014-09-11 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everyone with a professional interest in the flora of Texas will welcome this checklist of the vascular plants. This comprehensive list also includes crops, persistent perennials, and naturalized plants and encompasses over 1,000 changes to the previous (Hatch, 1990) checklist. The authors have arranged this checklist phylogenetically by classes following the Cronquist system. Several features make this checklist especially useful. Chief among them is the relative synonymy (name history). An extensive index makes current classification and correct nomenclature readily accessible, while the botanical bibliography is the most extensive ever compiled for Texas. The authors also note which plants have been listed as threatened or endangered by the Texas Organization of Endangered Species, which are designated as Federal Noxious Weeds, and which have been chosen as state tree, flower, fruit, etc. by the Texas Legislature.
Download or read book Brush Management written by Wayne T. Hamilton and published by Texas A&M University Press. This book was released on 2004-10-14 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of brush in rangeland environments continually tops the list of priority issues among landowners, and not just in Texas. Whether they manage their land for livestock, hunting, or wildlife watching, what to do about unwanted woody plants remains a serious and pervasive question for landowners everywhere. In the pages of this book, leading range management professionals introduce and explain not only the mechanisms of managing brush but also the changes in management philosophy and technology that have taken place over time. From the futile attempts at eradication to the successes of integrated brush management, expert practitioners examine mechanical, biological, chemical, and fire-related methods from three perspectives—the past, the present or “state-of-the-art,” and the future. In a final discussion, three specialists address the timely and important subject of brush management as it relates to water yield, economics, and wildlife. Brush Management: Past, Present, Future gives readers a straightforward and comprehensive view of a topic that remains a consistent concern for livestock, wildlife, and land management—one that will serve as a useful and interesting summary of the subject for teachers, students, landowners, and management professionals.

Download or read book 1997 IUCN Red List of Threatened Plants written by World Conservation Monitoring Centre and published by IUCN. This book was released on 1998 with total page 934 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the most comprehensive compilation of data on threatened vascular plants ever published. It includes the names of some 33,000 plant species determined to be rare or threatened on a global scale. Conservation assessments were provided by the IUCN Species Survival Commission, the National Botanical Institute (South Africa), Environment Australia, and CSIRO, The Nature Conservancy, the Smithsonian Institution, and the Royal Botanic Gardens, Kew, together with hundreds of botanic gardens and botanists throughout the world. The Royal Botanic Gardens Edinburgh and the New York Botanical Garden have made major in-kind contributions.The result of 20 years work by botanists and conservationists around the world, it is intended as a conservation tool, a provider of baseline information to measure conservation progress and as a primary source of data on plant species. Most importantly, however, it provides the building blocks on which to base a worldwide effort to conserve plant species.
