Download or read book Identification and Ecology of Southwest Australian Orchids written by Mark Brundrett and published by . This book was released on 2014-08-29 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the orchid family and describes unique features of their biology and ecology. Key topics include the global importance of Western Australia as an orchid diversity hotspot and the amazing interactions between orchids and pollinating insects. An overview on orchid conservation issues in WA and advice for orchid tourists are also provided along with a guide to identification with keys to orchid genera. Most chapters concern orchid identification with additional information on the pollination, ecology, cultivation and taxonomy of each genus. For each species, a brief description focuses on defining features with the majority of space used for photos. These chapters were designed to be user friendly and make identification as easy and accurate as possible.

This book was released on 2007 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Orchidaceae is characterized by a remarkably diverse range of life forms and some of the most highly specialized interactions with soil fungi and insect pollinators found in the flowering plants. Many species are rare or threatened with extinction either directly through loss of habitat or over-collection or, indirectly through debilitation or loss of mycorrhizal association or pollinator capacity. Australian temperate terrestrial orchids represent one of the most threatened groups in the Australian flora with many taxa clinging to existence in urban and rural bushland remnants, road verges and unprotected bushland. The aim of this study is to research and develop integrated conservation based on critical aspects of terrestrial orchid biology and ecology, towards the recovery of the rare and endangered Western Australian terrestrial orchid Caladenia huegelii. This study identified key aspects involved in an integrated conservation approach and research focused on conservation genetics, mycorrhizal interactions and in situ and ex situ conservation strategies for this species. Using polymorphic microsatellite molecular markers, high levels of genetic diversity were found within remnant populations of C. huegelii, while weak differentiation was observed among populations over the species geographic range. These results indicate historic genetic exchange between C. huegelii populations, a possible consequence of the sexually deceptive pollination strategy and the capacity for widespread seed dispersal. Symbiotic germination studies revealed compatibility barriers to C. huegelii germination with the orchid possessing a highly specific orchid-mycorrhizal association relative to common sympatric congeners. These results were reflected in a phylogenetic analysis of DNA sequences, revealing C. huegelii associates with only one endophyte species within the fungal family Sebacinaceae across its geographic range. Large scale in situ seed baiting demonstrated that endophytes compatible with C. huegelii were limited in distribution relative to common and widespread orchid species, a feature for C. huegelii that may be a major contributing factor in limiting the distributional range of the species. Detailed, within site seed baiting methods identified hotspots for mycorrhizal fungus compatible with C. huegelii that were unoccupied by the orchid. These mycorrhizal hotspots where used to investigate the effect of endophyte presence on survival of transplanted mature plants and seedling outplants. The in situ survival of glasshouse propagated seedlings was further optimized by incubating seedlings in growth containers before transfer to soil and outplanting seedlings in their second growing season. The findings of this study will substantially advance the recovery of C. huegelii and provide benchmark knowledge for similar projects with other rare and threatened terrestrial orchid species.

Available in PDF, EPUB and Kindle. Book excerpt: Written by world leaders in the field, this first ever comprehensive reference on terrestrial orchids concisely explains the procedures necessary for their conservation and restoration. It includes beautiful color illustrations, methods and techniques in the utilization of modern technology and case studies to illustrate key principles and success stories. It covers topics such as monitoring, approaches used for mycorrhizal isolation and culture, seed sowing techniques, soil baiting, symbiotic culture of terrestrial species, translocation of propagated plants, pollination, genetic approaches for orchid biology and conservation, innovations in alginate encapsulation of seed and mycorrhizal fungus, and more. With terrestrial orchids now among the worlds most threatened plants, the need for conservation is paramount. It will equip orchid biologists, botanists, conservationists, students, and hobbyists with the necessary methodologies to facilitate the conservation of this endangered group of orchids. Although the focus is on terrestrial orchids, the techniques described in this book can also be applied equally to epiphytic (tree) orchids. Key Features -Clearly and concisely explains the procedures necessary for terrestrial orchid conservation and restoration -Offers methods and techniques complete in their detail, utilization of modern technology, simplicity, and ease of application across species from different parts of the world -Provides stand-alone guidance in each chapter and collectively enables practitioners to undertake what were previously considered complex scientific procedures -Includes relevant case studies to illustrate key principles and success stories in orchid conservation, written by world leaders in orchid conservation practice and science -Relates many of the techniques and procedures to epiphytic orchids to increase the appeal of the book to all orchid conservationists

Available in PDF, EPUB and Kindle. Book excerpt: Faced with widespread and devastating loss of biodiversity in wild habitats, scientists have developed innovative strategies for studying and protecting targeted plant and animal species in "off-site" facilities such as botanic gardens and zoos. Such ex situ work is an increasingly important component of conservation and restoration efforts. Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr., Kayri Havens, and Mike Maunder, is the first book to address integrated plant conservation strategies and to examine the scientific, technical, and strategic bases of the ex situ approach. The book examines where and how ex situ investment can best support in situ conservation. Ex Situ Plant Conservation outlines the role, value, and limits of ex situ conservation as well as updating best management practices for the field, and is an invaluable resource for plant conservation practitioners at botanic gardens, zoos, and other conservation organizations; students and faculty in conservation biology and related fields; managers of protected areas and other public and private lands; and policymakers and members of the international community concerned with species conservation.
