Winner of the 2021 Gerald Lampert Memorial Award! Winner of the Stephan G. Stephansson Award for Poetry Winner of a 2021 High Plains Book Award for First Book! Finalist for the 2020 City of Calgary W.O. Mitchell Book Prize! A 2020 CBC Poetry Book of the Year! Finalist for a 2021 High Plains Book Award for Poetry Bertrand Bickersteth's debut poetry collection explores what it means to be black and Albertan through a variety of prisms: historical, biographical, and essentially, geographical. The Response of Weeds offers a much-needed window on often overlooked contributions to the province's character and provides personal perspectives on the question of black identity on the prairies. Through these rousing and evocative poems, Bickersteth uses language to call up the contours of the land itself, land that is at once mesmerizing as it is dismissively effacing. Such is black identity here on this paradoxical land, too.

This book presents a whole-plant perspective on plant integrated responses to multiple stresses, including an analysis of how plants have evolved growth forms and phenological responses to cope with changing stress patterns in natural environments. - Explores stress responses at both the structural and process levels - Outlines structural, phenological, and physiological responses that optimize production under multiple stresses - Combines physiological and evolutionary perspectives

Social Justice Poetry Spoken-word poet Valerie Mason-John unsettles readers with potent images of ongoing trauma from slavery and colonization. Her narratives range from the beginnings of the African Diaspora to the story of a stowaway on the Windrush, from racism and sexism in Trump’s America to the wide impact of the Me Too movement. Stories of entrapment, sexual assault, addictive behaviours, and rave culture are told and contrasted to the strengthening and forthright voice of Yaata, Supreme Being. I Am Still Your Negro is truth that needs to be told, re-told, and remembered. I was your Negro Captured and sold I am still your negro Arrested and killed —from “I Am Still Your Negro”

Responses of Plants to Air Pollution examines the effects of air pollutants, individually and synergistically, on both higher and lower plants. The subject matter overlaps into a wide range of disciplines including agronomy, plant anatomy, biochemistry, cryptogamic botany, ecology, entomology, forestry, horticulture, landscape architecture, meteorology, microscopy, plant pathology, plant physiology, and soil science. The opening chapter presents an overview of sources of air pollution, costs of air pollution, and mechanisms of pollution injury to plants. Separate chapters on sulfur dioxide, ozone, fluorides, peroxyacyl nitrates, oxides of nitrogen, and particulates follow. Subsequent chapters are devoted to plant responses to combinations of pollutants; to effects of pollutants on plant ultrastructure, on forests, and on lichens and bryophytes; to interactions of pollutants with canopies of vegetation; to interactions of pollutants and plant diseases; and to interactions of pollutants with agricultural practices. This book will be useful to scientists in many disciplines as well as those who share the concern that clean air can no longer be expected to be the normal environment for plants or animals. The book will also be a valuable a reference work or text for upper level undergraduate students, graduate students, researchers, and growers of plants.

Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.

Weeds are problematic both in agricultural and non-agricultural areas so that they potentially cause economic losses. Weed interference in crops also date back to the beginning of agriculture and they have been able to persist, in spite of long term control operations. They are able to adapt and survive in the environment due to their specific characteristics. Thus, to control weeds efficiently knowledge of weed biology, in particular their survival mechanisms, ecological responses and interactions, is of important value in weed management systems. "Weeds and their Ecological Functions" provides information on weeds functional behaviours in their cultivations including weed seed dormancy, germination and seedling emergence, examples of beneficial and detrimental interactions between weeds and other organisms, weed behaviours in perennial crops and response of weeds to cover crops. This information is useful for students and weed scientists to analyse some of the functional behaviour of weeds and to develop integrated weed management systems.

Invasive Plants of the Upper Midwest is an informative, colorful, comprehensive guide to invasive species that are currently endangering native habitats in the region. It will be an essential resource for land managers, nature lovers, property owners, farmers, landscapers, educators, botanists, foresters, and gardeners. Invasive plants are a growing threat to ecosystems everywhere. Often originating in distant climes, they spread to woodlands, wetlands, prairies, roadsides, and backyards that lack the biological controls which kept these plant populations in check in their homelands. Invasive Plants of the Upper Midwest includes more than 250 color photos that will help anyone identify problem trees, shrubs, vines, grasses, sedges, and herbaceous plants (including aquatic invaders). The text offers further details of plant identification; manual, mechanical, biological, and chemical control techniques; information and advice about herbicides; and suggestions for related ecological restoration and community education efforts. Also included are literature references, a glossary, a matrix of existing and potential invasive species in the Upper Midwest, an index with both scientific and common plant names, advice on state agencies to contact with invasive plant questions, and other helpful resources. The information in this book has been carefully reviewed by staffs of the Wisconsin Department of Natural Resources Bureau of Endangered Resources and the University of Wisconsin-Madison Arboretum and other invasive plant experts.
