Download or read book Flora of North America North of Mexico written by Flora of North America Editorial Committee, and published by OUP USA. This book was released on 2006-04-06 with total page 952 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flora of North America brings together for the first time ever in a concise and easy to understand format information on all of the plants growing spontaneously in North America north of Mexico. Volume 24 of Flora North America is one of two volumes on grasses to be published in this series (Volume 25, though it follows sequentially, was published in 2003). Together they will provide a comprehensive, authoritative, illustrated account of this important group of plants. Most of the species treated are either native to North America north of Mexico or are introduced species that are now established in the region, but there are many that do not fit into these categories. Among the additional species are several that the USDA has identified as major weed threats; and others that are known only as cultivated plants, some being cultivated for their ornamental value, others as sources for human food or animal forage. For instance, volume 24 includes such ecologically important genera as Elymus (wheatgrasses), Poa (bluegrasses), and Festuca (fescues), economically important species such as Triticum (wheat), Hordeum (barley), Oryza (rice), and Zizania (wild rice), several ornamental species, including some bamboos, and noxious weeds such as Elymus repens (quackgrass), and Bromus tectorum (cheatgrass). The volume includes identification keys, descriptions, line drawings, and ecological characteristics for each of the species; distribution maps for the native and established species; and a list of commonly encountered synonyms for the accepted names. The treatments, each of which has been extensively reviewed, are based on a combination of original observations and critical review of the literature.
Download or read book Aquatic Monocotyledons of North America written by Donald H. Les and published by CRC Press. This book was released on 2020-05-10 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together information on the natural history, ecology and systematics of North American aquatic monocotyledons. The book is an overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference sources. Information on more than 300 species in 87 genera of monocotyledons will be included. Recent phylogenetic analyses will be incorporated. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. Key Selling Features: The primary source of natural history information on aquatic plants Comprehensive lists of ecological associates Synthetic overview of systematic relationships of aquatic species and genera Practical information for rare and invasive plant managers Essential guide to facilitate wetland delineation

Download or read book Wildland Fire in Ecosystems written by and published by Forest Service. This book was released on 2008 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This state-of-knowledge review of information on relationships between wildland fire and nonnative invasive plants can assist fire managers and other land managers concerned with prevention, detection, and eradication or control of nonnative invasive plants. The 16 chapters in this volume synthesize ecological and botanical principles regarding relationships between wildland fire and nonnative invasive plants, identify the nonnative invasive species currently of greatest concern in major bioregions of the United States, and describe emerging fire-invasive issues in each bioregion and throughout the nation. This volume can help increase understanding of plant invasions and fire and can be used in fire management and ecosystem-based management planning. The volume's first part summarizes fundamental concepts regarding fire effects on invasions by nonnative plants, effects of plant invasions on fuels and fire regimes, and use of fire to control plant invasions. The second part identifies the nonnative invasive species of greatest concern and synthesizes information on the three topics covered in part one for nonnative invasives in seven major bioregions of the United States: Northeast, Southeast, Central, Interior West, Southwest Coastal, Northwest Coastal (including Alaska), and Hawaiian Islands. The third part analyzes knowledge gaps regarding fire and nonnative invasive plants, synthesizes information on management questions (nonfire fuel treatments, postfire rehabilitation, and postfire monitoring), summarizes key concepts described throughout the volume, and discusses urgent management issues and research questions.

Download or read book Aquatic Dicotyledons of North America written by Donald H. Les and published by CRC Press. This book was released on 2017-09-01 with total page 3174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic Dicotyledons of North America: Ecology, Life History, and Systematics brings together a wealth of information on the natural history, ecology, and systematics of North American aquatic plants. Most books on aquatic plants have a taxonomic focus and are intended primarily for identification. Instead, this book provides a comprehensive overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference materials. Included dicotyledon species are those having an obligate (OBL) wetland status, a designation used in the USACE National Wetland Plant List. Recent phylogenetic analyses are incorporated and rationale is provided for interpreting this information with respect to species relationships. This diverse assemblage of information will be useful to a wide range of interests including academic researchers, wildlife managers, students, and virtually anyone interested in the natural history of aquatic and wetland plants. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. This book is an essential resource for assisting with wetland delineation.
