The first single, comprehensive source for locating North American public prairies, grasslands, and savannas, Prairie Directory of North America is a guide unlike any other. First published in 2001, the book uniquely catalogs the continent's most well-known prairie sites by country and state for easy reference. With the addition of over three hundred newly located, preserved, or restored sites, the second edition is the prairie enthusiast's ideal guide to locating countless North American sites-from the well-documented to the remote. Readers can use the guide to plan both convenient visits to close-to-home prairies and journeys to sites well across the continent. Also included is an expanded state-by-state index, ideal for locating specific prairies in any given state. The victim of destructive plowing and construction at the hands of European settlers, North American grassland ecosystems that once spanned the entire continent have suffered degradation and fragmentation. With the Prairie Directory as a guide, however, ecologists, environmental scientists, and tourists can experience the essence of this ancient ecosystem and, in some locations, even its vastness. The book lists tiny, hidden half-acre prairies spared by the plow as well as popular sites covering millions of acres. It documents prairies hidden deep in forests or in plain sight in American Indian reservations. The only one of its kind, this book will allow readers to experience the prairie as a colorful, fragrant, wildlife-rich North American landscape.

Africa has been and continues to be a significant source of medicinal and aromatic plants and botanicals to the world's food, drug, herb and dietary supplement market, and in the past decade numerous African plant materials have established a strong international market presence. This book provides an excellent opportunity to delve into the current and future contributions that African plants can and will continue to make both internal to Africa and on the global stage. This book expertly covers various medicinal plants of African origin and the some of the latest basic and clinical research supporting their ongoing and potential uses in self-care and healthcare. This work also examines various issues and trends in medicinal plants from their uses in Traditional Medicine and ethnobotany, to our modern understanding of the plants chemistry and pharmacognosy, natural products chemistry and applications of medicinal plants, quality control, and models of benefit sharing.

Viruses that infect plants are responsible for reduction in both yield and quality of crops around the world, and thus are of great economic importance. This has provided the impetus for the extensive research into the molecular and cellular biology of these pathogens and into their interaction with their plant hosts and their vectors. However, interest in plant viruses extends beyond their ability to damage crops. Many plant viruses - for example, tobacco mosaic virus - have been used as model systems to provide basic understanding of how viruses express genes and replicate. Others permitted the elucidation of the processes underlying RNA silencing, now recognized as a core epigenetic mechanism underpinning numerous areas of biology. This book attests to the huge diversity of research in plant molecular virology. Written by world authorities in the field, the book opens with two chapters on the translation and replication of viral RNA. Following chapters cover topics such as viral movement within and between plants, plant responses to viral infection, antiviral control measures, virus evolution, and newly emerging plant viruses. The book concludes with two chapters on biotechnological applications of plant viruses. Throughout, the focus is on the most recent, cutting-edge research, making this book essential reading for everyone working with plant viruses.

Volume 4 of the critically acclaimed Flora of North America series is one of 19 volumes on dicots to be published in this collection. 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. It also includes many important species that do not fit into these categories.

Although the problem of controlling the spread of exotic invasive plant and animal species in the United States has been recognized for quite some time, it has been lacking an adequate legislative mandate, public awareness, and sufficient funding to meet the challenge. This ACS Symposium Series title showcases the many diverse efforts being made to control invasive species at the federal, state, and local levels. It recognizes the global extent of the problem and compares the methods used in other countries with those of the U.S., and includes recommendations of how best to proceed from here.

Flora of North America, Volume 3, provides information on many of the most familiar wildflowers and trees in North America. Included are treatments of the buttercup family (Ranunculacaeae), with such plants as delphiniums and columbines, and the poppy family (Papveraceae). Most of the important broadleaf tree species are covered, including the oaks (Fagaceae), elms (Ulmaceae), birches (Betulaceae), walnuts (Juglandaceae), plane trees (Plantanaceae), and magnolias (Magnoliaceae). Many striking families are covered, such as the dutchman's pipe family (Aristochiaceae), and the aquatic families Nymphaeceae (water lilies), and Melumbonaceae (lotus).

Identification keys, summaries of habitats and geographic ranges, distribution maps, pertinent synonymies, descriptions, chromosome numbers, phenological information, and other significant biological observations are given for each species. The treatments, written and reviewed by experts throughout the systematic botanical community, are based on original observations of herbarium specimens, and wherever possible, on living plants. These observations are supplemented by critical reviews of the literature.

Sunday Times Bestseller 'A paradigm-smashing chronicle of joyous entanglement' Charles Foster Waterstones Non-Fiction Book of the Month (September) Are trees social beings? How do trees live? Do they feel pain or have awareness of their surroundings? In The Hidden Life of Trees Peter Wohlleben makes the case that the forest is a social network. He draws on groundbreaking scientific discoveries to describe how trees are like human families: tree parents live together with their children, communicate with them, support them as they grow, share nutrients with those who are sick or struggling, and even warn each other of impending dangers. Wohlleben also shares his deep love of woods and forests, explaining the amazing processes of life, death and regeneration he has observed in his woodland. A walk in the woods will never be the same again.

Flora of North America, Volume 22, is the first of five volumes covering monocots in North America, north of Mexico.

In this book Adrian Koopman details the complex relationship between plants, the Zulu language and Zulu culture. Zulu plant names do not just identify plants, they tell us a lot more about the plant, or how it is perceived or used in Zulu culture. For example, the plant name umhlulambazo (what defeats the axe’ tells us that this is a tree with hard, dense wood, and that usondelangange (come closer so I can embrace you) is a tree with large thorns that snag the passer-by. In a similar vein, both umakuphole (let it cool down) and icishamlilo (put out the fire) refer to plants that are used medicinally to treat fevers and inflammations. Plants used as the base of love-charms have names that are particularly colourful, such as unginakile (she has noticed me), uvelabahleke (appear and they smile) and the wonderfully named ungcingci-wafika-umntakwethu (how happy I am that you have arrived, my sweetheart!). And then there are those plant names that are just plain intriguing, if not mystifying: umakhandakansele (the heads of Mr Ratel), isandlasonwabu (hand of a chameleon), intombikayibhinci (the girl does not wear clothes) and ukhuningomile (piece of firewood, I am thirsty).

Andre Laurendeau was the most widely respected French-Canadian nationalist of his generation. The story of his life is to a striking degree also the story of French-Canadian nationalism from the 1930s to the 1960s, that period of massive societal change when Quebec evolved from a traditional to a modern society. The most insightful intellectual voice of the nationalist movement, he was at the tumultuous centre of events as a young separatist in the 1930s; an anti-conscription activist and reform-minded provincial politician in the 1940s; and an influential journalist, editor of the Montreal daily Le Devoir, in the 1950s. At the same time he played an important role in Quebec's cultural life both as a novelist and playwright and as a well-known radio and television personality. In tracing his life story, this biography sheds indispensable light not only on the development of Laurendeau's own nationalist thought, but on his people's continuing struggle to preserve the national values that make them distinct.

In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this "chemical network" is still negligible. Chemical interactions can be divided into two larger sub-areas based on the function of the chemical substance. First, there are interactions where chemical substances are toxic to other organisms and are used as a defence against consumers (including both herbivores and predators) or a weapon against competitors (allelopathy). Second, chemical substances may be used as a source for information of the environment; for example: how can I find the optimal habitat, the best food, the nicest partner, and avoid being eaten? Aquatic organisms are able to detect and respond to extremely low concentrations of chemical cues to answer all these questions. The book aims at connecting these intriguing chemical interactions with traditional knowledge of organism interactions. Chemical Ecology of Aquatic Systems covers a wide range of studies, both plant and animal, from different geographic regions and habitats - pelagic as well as benthic. Most of the chemical interactions are similar in freshwater and marine habitats and this book therefore strives at integrating work on both systems.
