Download or read book Measuring and Monitoring Plant Populations written by Caryl Elzinga and published by Createspace Independent Publishing Platform. This book was released on 2015-01-02 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical reference applies to monitoring situations involving a single plant species, such as an indicator species, key species, or weed. It was originally developed for monitoring special status plants, which have some recognized status at the Federal, State, or agency level because of their rarity or vulnerability. Most examples and discussions in this technical reference focus on these special status species, but the methods described are also applicable to any single-species monitoring and even some community monitoring situations.We thus hope wildlife biologists, range conservationists, botanists, and ecologists will all find this technical reference helpful.

Download or read book Pollination Biology written by Dharam P. Abrol and published by Springer Science & Business Media. This book was released on 2011-10-05 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Download or read book Ex Situ Plant Conservation written by Center for Plant Conservation and published by Island Press. This book was released on 2013-02-22 with total page 536 pages. 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.

Download or read book 100 Plants to Feed the Bees written by The Xerces Society and published by Storey Publishing. This book was released on 2016-11-29 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international bee crisis is threatening our global food supply, but this user-friendly field guide shows what you can do to help protect our pollinators. The Xerces Society for Invertebrate Conservation offers browsable profiles of 100 common flowers, herbs, shrubs, and trees that support bees, butterflies, moths, and hummingbirds. The recommendations are simple: pick the right plants for pollinators, protect them from pesticides, and provide abundant blooms throughout the growing season by mixing perennials with herbs and annuals! 100 Plants to Feed the Bees will empower homeowners, landscapers, apartment dwellers — anyone with a scrap of yard or a window box — to protect our pollinators.

Download or read book The Biology of Rarity written by W.E. Kunin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book began life as a review article. That article spawned a symposium which was, in turn, greatly expanded to form the present volume. As the project moved through these developmental stages (hopefully, towards attainment of its full maturity), a number of people have provided invaluable assistance to us, and we would like to take this opportunity to thank them. Gordon Orians must certainly take a high place in that list. He has been both a friend and mentor to W.E.K., and many of the topics explored in this book have emerged from the resultant dialogue. His thought processes, ideas and perhaps even some of his turns of phrase emerge throughout much ofthe book. Gordon also played a pivotal role in inviting in motion, and so he has served as a catalyst the article that set this project to the book as well as one of its reagents. While he has not served as an editor of this book, he is one of its authors in more than just the literal sense.

Book excerpt: This book provides a compact, up-to-date and detailed overview of the vegetation of the Iberian Peninsula, a highly diverse part of Europe in the Mediterranean area. Written by a group of experienced researchers, the volume includes a first section with general chapters discussing the climate, the biogeography and the flora, and a second section with detailed descriptions of the 14 regional sectors into which the peninsula and Balearic Islands have been divided. A third section explores special features, such as aquatic vegetation, gypsum and dolomite vegetation, coastal vegetation, mountain flora and vegetation, conservation issues and alien flora.

Download or read book The Pollen Wasps written by Sarah K. Gess and published by . This book was released on 1996 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 25 color plates and 60 black-and-white illustrations offer readers a rare close look at this little-known and endangered group of insects. Three appendixes list all known flower-visiting records, all hymenopteran visitors to the flowers included in the pollination chapter, and all published species names for Masarinae. Pollen wasps are of interest to a wide range of scholars (including entomologists, ethologists, ecologists, and evolutionary biologists) because of their close associations with flowering plants and because of the ability of certain species to produce silk for nest building--an intriguing case of convergent evolution. For these readers, and for students of natural history and proponents of species preservation, The Pollen Wasps will prove an invaluable resource.
