Download or read book Biodiversity Conservation and Sustainability in Asia written by Münir Öztürk and published by Springer Nature. This book was released on 2021-04-24 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the world’s seven continents, Asia is the largest. Its physical landscapes, political units, and ethnic groups are both wide-ranging and many. Southwest, South and Middle Asia are highly populated regions which, as a whole, cover an extremely large area of varied geography. In total, this domain is unique in its plant diversity and large vegetation zones with different communities and biomes. It is rich in endemics, with specific and intraspecific diversity of fruit trees and medicinal plants, including a number of rare, high value, species. At the same time, much of the land in the region is too dry or too rugged, with many geographical extremes. Overgrazing, oil and mineral extraction, and poaching are the major threats in the area. This two-volume project focuses on the dynamic biodiversity of the region with in-depth analysis on phytosociology, plants, animals and agroecology. There are also chapters that explore new applications as well as approaches to overcome problems associated with climate change. Much of the research and analysis are presented here for the first time. We believe this work is a valuable resource for professionals and researchers working in the fields of plant diversity and vegetation, animal diversity and animal populations, and geo-diversity and sustainable land use, among others. The first volume guides our readers to West Asia and the Caucasus region, while volume two focuses on issues unique to South and Middle Asia.

Color photos of over 700 weeds including seeds, seedlings, flowers, and mature plants. Appendix of non-native plants rarely or occasionally naturalized in California. Glossary of botanical terms. Bibliography of some of the most pertinent publications. Index to common names, scientific names, and synonyms. Each entry describes the plant category, family name, common name, and synonyms along with a summary of the important aspects of the plant’s life cycle, size, growth form, impact, method of introduction, and toxicity. You'll also find a description of the seedling, mature plant, roots and underground structures, flowers, fruits and seeds, spikelets and florets, spore-bearing structures, and post senescence characteristics for each entry. Also includes a description of the habitat where each is typically found and distribution in California, other states, and worldwide, along with maximum elevation at which the species is found. Rounding out each entry is a description of the methods of reproduction, seed dispersal, germination requirements and conditions, seed survival and longevity, early establishment characteristics and requirements, cultural practices and management options that have proven effective or ineffective in controlling infestations, and a notation of the species' inclusion on federal or state noxious weed lists.
