Download or read book Systematics Evolution and Biogeography of Compositae written by Vicki Ann Funk and published by . This book was released on 2009 with total page 1008 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This spectacular book does full justice to the Compositae (Asteraceae), the largest and most successful flowering plant family with some 1700 genera and 24,000 species. It is an indispensable reference, providing the most up-to-date hypotheses of phylogenetic relationships in the family based on molecular and morphological characters, along with the corresponding subfamilial and tribal classification. The 2009 work not only integrates the extensive molecular phylogenetic analyses conducted in the last 25 years, but also uses these to produce a metatree for about 900 taxa of Compositae. The book contains 44 chapters, contributed by 80 authors, covering the history, economic importance, character variation, and systematic and phylogenetic diversity of the family. The emphasis of this work is phylogenetic; its chapters provide a detailed, current, and thoroughly documented presentation of the major (and not so major) clades in the family, citing some 2632 references. Like the Compositae, the book is massive, diverse, and fascinating. It is beautifully illustrated, with 170 figures, and an additional 108 cladograms (all consistently color-coded, based on the geographic range of the included taxa); within these figures are displayed 443 color photographs, clearly demonstrating the amazing array of floral and vegetative form expressed by members of the clade." --NHBS Environment Bookstore.

Available in PDF, EPUB and Kindle. Book excerpt: Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.
