Book excerpt: The IUCN/SSC Cycad ACtion Plan brings together the best available information on this ancient and fascinating group of plants. Cycads were a dominant part of the earth's flora during the age of the dinosaurs and many species were common even in more recent times. However, many of the 297 species and subspecies dealt with in the Cycad Action Plan have been badly affected by habitat destruction and plant collecting within the last century. As a result, more than half the known species are now classified as threatened, and the cycads stand out as one of the most threatened groups of plants in this world.The Action Plan provides an overview of all the cycads and the threats to their survival. This is followed by separate assessments for the four broad regions where cycads now occur, namely Africa and the Indian Ocean Islands, Australia, Asia, and the New World. Trade in cycads has had a substantial impact on wild cycad populations and there is a separate chapter on trade and the effectiveness of control measures such as CITES. In addition, with so many species facing extinction in the wild, garden collections have become increasingly important and we have assessed the global status of cycad collections.Finally, the Cycad Action Plan presents a set of objectives and actions to reduce the threat to cycads in the wild and to provide ex situ conservation for those that almost certainly will become extinct in the wild. Wherever possible, we have tried to identify and build on innovative projects, such as community-based nurseries, and to link cycad consideration with other global and local initiatives such as the conservation of biodiversity hotspots.

Download or read book Under the Shade of Thipaak written by Michael D. Carrasco and published by University Press of Florida. This book was released on 2022-08-30 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Society for Ethnobotany Daniel F. Austin Award The important cultural role of an ancient, endangered plant Under the Shade of Thipaak is the first book to explore the cultural role of cycads, plants that evolved over 250 million years ago and are now critically endangered, in the ancient and modern Mesoamerican and Caribbean worlds. This volume demonstrates how these ancient plants have figured prominently in regional mythologies, rituals, art, and foodways from the Pleistocene-Holocene transition to the present. Contributors discuss the importance of cycads from a variety of disciplinary perspectives, including biology and population genetics, historical ecology, archaeology, art history, linguistics, and conservation and sustainability. Chapters pay special attention to the enduring conceptual relationships between cycads and maize. This book demonstrates how a close examination of cycad-human relationships can motivate conservation of these threatened plants in ways that engage local communities, as well as promote the significance of ancient and modern practices that unite nature and culture.

Download or read book Biodiversity Conservation and Phylogenetic Systematics written by Roseli Pellens and published by Springer. This book was released on 2016-02-24 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.

Download or read book The Writings of Ferdinand Lindheimer written by John E. Williams and published by Texas A&M University Press. This book was released on 2020-09-25 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferdinand Jacob Lindheimer is known as the “father of Texas botany.” While he was not the first botanist to collect plants for scientific examination in Texas, his collections are credited with helping botanists around the world to understand the nature, extent, and significance of the diversity of plants in the state. In partnership with Asa Gray of Harvard University, Lindheimer spent eight years collecting Texas plants to distribute to a list of paying subscribers—including places like the British Museum, the Royal Botanic Gardens at Kew, and the Smithsonian Institution. Today, no fewer than 362 plant names are based, at least in part, on Lindheimer collections, and 65 plants have been named in his honor. Lindheimer was a founding settler of New Braunfels, raising his family on the banks of the Comal River while he continued to collect and ship plant specimens. He was “elected” as the first editor of the Neu-Braunfelser Zeitung (still published today as the Herald-Zeitung), and served from 1852 to 1872. He wrote a number of articles for the Zeitung on topics ranging from plants, climate, and agriculture to Texas Indian affairs, optimism, and teaching schoolchildren. In the last year of Lindheimer’s life, one of his students worked with him to collect an assortment of his essays and articles from the Zeitung. In 1879, the collection was published as Aufsätze und Abhandlungen von Ferdinand Lindheimer in Texas (Essays and Articles of Ferdinand Lindheimer in Texas). John E. Williams now offers the first English translation of these essays, which provides valuable insight into the natural and cultural history of Texas.

Download or read book The Biology of the Cycads written by Knut Norstog and published by Comstock Publishing Associates. This book was released on 1997 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thoroughly referenced and generously illustrated, this book discusses all aspects of cycadology. A small group of ancient palmlike seed plants noted for their beautiful foliage and often brightly colored cones and seeds, cycads are believed to have been among the first seed-bearing plants. Seed bearing was the basis for their worldwide dominance from about 300 million years ago to about 70 million years ago, when today's familiar flowering plants gained ascendancy. In recent years, interest in cycads has increased, partly as a result of the need for a more complete identification of the range of toxic and carcinogenic substances these plants produce and partly because of the recognition that some compounds from cycads may prove valuable in biomedical research. Many cycads have recently been identified as endangered species, including some that seem to have survived virtually unchanged since the Mesozoic era. Cycads have a specific importance, now at risk of being lost forever, for the information they offer on the origins and evolution of seed plants. Knut J. Norstog and Trevor J. Nicholls discuss cycad anatomy, reproduction, physiology, and growth. They also focus on population biology and the fossil cycadophytes, as well as genera and species from both the Old World and the New World. The Biology of the Cycads is illustrated with numerous maps, diagrams, and drawings, as well as more than 350 photographs, in black and white and in color.
