Wetland Ecology and Management: Case Studies
This book contains papers on the topics of brought together wetland SCientists from all wetland ecology and management, most of continents and provided an opportunity to exchange valuable information on a variety of which were presented at the 2nd International Wetlands Conference in Trebon, Czechoslovakia aspects on the ecology and management of wetlands. (13-22 June 1984). The conference, hosted by the Hydrobotany Department of the Institute of Botany, was organized by the Czechoslovak This volume contains papers that represent aspects of wetland management. Like most Academy of Sciences and the International ecological topics, the papers clearly Wetlands Working Group of the International...
Allelopathy in Sustainable Agriculture and Forestry
Simply put, allelopathy refers to an ecological phenomenon of plant-plant interference through release of organic chemicals (allelochemicals) in the environment. These chemicals can be directly and continuously released by the donor plants in their immediate environment as volatiles in the air or root exudates in soil or they can be the microbial degradation products of plant residues. The chemicals may interfere with survival and growth of neighboring or succeeding plants. Black walnut, eucalyptus, sunflower, sorghum, sesame and alfalfa are common examples of plants with allelopathic property as well as some staple crops such as rice, wheat, barley and sorghum. Plants can emit chemicals tha...
Environmental Law for Biologists
Environmental law has an unquestionable effect on the species, ecosystems, and landscapes that biologists study—and vice-versa, as the research of these biologists frequently informs policy. But because many scientists receive little or no legal training, we know relatively little about the precise ways that laws affect biological systems—and, consequently, about how best to improve these laws and better protect our natural resources. With Environmental Law for Biologists, ecologist and lawyer Tristan Kimbrell bridges this gap in legal knowledge. Complete with a concise introduction to environmental law and an appendix describing the most important federal and international statutes and ...
Canadian Environmental Philosophy
Canadian Environmental Philosophy is the first collection of essays to take up theoretical and practical issues in environmental philosophy today, from a Canadian perspective. The essays cover various subjects, including ecological nationalism, the legacy of Grey Owl, the meaning of “outside” to Canadians, the paradigm shift from mechanism to ecology in our understanding of nature, the meaning and significance of the Anthropocene, the challenges of biodiversity protection in Canada, the conservation status of crossbred species in the age of climate change, and the moral status of ecosystems. This wide range of topics is as diverse and challenging as the Canadian landscape itself. Given the extent of humanity's current impact on the biosphere – especially evident with anthropogenic climate change and the ongoing mass extinction – it has never been more urgent for us to confront these environmental challenges as Canadian citizens and citizens of the world. Canadian Environmental Philosophy galvanizes this conversation from the perspective of this place.
Allelopathic Potential of Large Leaved Aster (Aster Macrophyllus L.)
Describes laboratory studies conducted to determine the allelopathic potential of water extracts of leaves and soil of large-leaved aster (Aster macrophyllus L.) using lettuce and black spruce seedling bioassays. Effects of the extracts on seed germination and seedling growth on the two plants are described and discussed, with reference to the possible presence of water-soluble phytotoxic substances in aster leaves.
