Book excerpt: Natural history has always been the foundation of conservation biology. For centuries, botanists collected specimens in the field to understand plant diversity; now that many habitats are threatened, botanists have turned their focus to conservation, and, increasingly, they look to the collections of museums, herbaria, and botanical gardens for insight on developing informed management programs. Plant Conservation explores the value of these collections in light of contemporary biodiversity studies. Plant Conservation opens with a broad view of plant biodiversity and then considers evolutionary and taxonomic threats and consequences of habitat alteration; specific threats to plant diversity, such as invasive species and global climate change; consequences of plant population decline at the ecological, evolutionary, and taxonomic levels; and, finally, management strategies that protect plant biodiversity from further decline. With a unique perspective on biodiversity and scientific collections, Plant Conservation ultimately emphasizes the role museums and botanical gardens will play in future conservation.

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.

Download or read book Recent Advances in Lichenology written by Dalip Kumar Upreti and published by Springer. This book was released on 2016-10-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses in detail molecular, mycobiont culture, biomonitoring and bioprospection of lichens, providing insights into advances in different fields of lichenology by applying modern techniques and approaches and examining how their application has enhanced or changed classical approaches. It offers a valuable resource, especially for beginners, students and researchers from different academic backgrounds interested in the study of lichens. In recent years, the introduction of modern analytical techniques and approaches has significantly improved our understanding of the environment, including lichens. Lichens are unique organisms which possess untapped potential as effective and reliable bioindicators, sources of therapeutic phytochemicals, and as excellent extremophiles. The unique and peculiar characteristics of lichens underline the need for a multidimensional approach to explore their potential in various fields of environment science, botany and chemistry. Modern techniques, especially molecular techniques, have greatly enriched the field of lichen taxonomy and its position in the plant kingdom, revealing little-known species and exploring their evolutionary history, while multivariate analysis and GIS approaches have established lichens as an ideal and reliable tool for monitoring air pollution. Advanced culture techniques have expanded the pharmacological applications of lichens, which was formerly restricted due to their small biomass. The advent of sophisticated analytical instrumentation has now facilitated the isolation and characterization of lichens’ bioactive constituents, even in lower concentrations, as well as the estimation of their stress responses at different levels of pollution. As lichen diversity is adversely affected by increasing air pollution, there is a pressing need to develop effective management practices to conserve, restore and document lichen diversity.
