Book Description
Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book categoryLesser Prairie-Chickens have experienced substantial declines in terms of population and the extent of area that they occupy. While they are an elusive species, making it difficult at times to monitor them, current evidence indicates that they have been persistently

Book Description
Paul Johnsgard, one of the world's leading ornithologists, has written this book as a call to action. Conservationists have seen a marked decline in the populations of North American grouse, particularly the grassland-adapted species. Unless action is taken swiftly, at least one species -- Attwater's prairie-chicken -- is certain to follow the heath hen into extinction. Johnsgard begins with the tragic history of the heath hen, which became extinct in 1932. He devotes a chapter each to the greater and lesser prairie-chickens, greater and Gunnison sage-grouse, and sharp-tailed grouse. Johnsgard argues that habitat loss and excessive hunting are major factors contributing to the decline of each species, particularly the lesser prairie-chicken and the Gunnison sage-grouse, which have been proposed for threatened federal status. This narrative history is troubling but not without hope. Johnsgard discusses places where populations exist that have yet to be preserved, and outlines the steps necessary to conserve these species. A possible future does exist for grassland grouse, and Johnsgard's book points the way toward securing it.

Book Description
Grouse—an ecologically important group of birds that include capercaillie, prairie chickens, and ptarmigan—are distributed throughout the forests, grasslands, and tundra of Europe, Asia, and North America. Today, many grouse populations are in decline, and the conservation and management of these charismatic birds is becoming a global concern. This volume summarizes current knowledge of grouse biology in 25 chapters contributed by 80 researchers from field studies around the world. Organized in four sections—Spatial Ecology, Habitat Relationships, Population Biology, and Conservation and Management—the chapters offer important insights into spatial requirements, movements, and demography of grouse. Much of the research employs emerging tools in ecology that span biogeochemistry, molecular genetics, endocrinology, radio-telemetry, and remote sensing. The chapters explore topics including the impacts of climate change, energy development, and harvest, and give new evidence for life-history changes in response to human activities.

Book Description
This volume contains two sections: Mechanisms of herbicidal action (chapters 1-4) and Mode of action of selected herbicides on controlling diseased, weed growth and productivity and/or growth and development of field crops (chapters 5-10). Topics by chapters are: molecular mechanism of action, immunosensors , laboratory studies, molecular modeling, weed resistance, community response, use of herbicides in biotech culture, gene flow, herbicides and risk, herbicides persistence. These recurring themes reinforce my view, held over a very long time, that experience with one crop or problem can sometimes be relevant, often to an unexpected extent, to an apparently dissimilar situation in a different crop. I hope that readers interested in herbicides and pesticides will be satisfied with all the chapters in the book as its content might be of interest and value to them in the future.
