Biology of Populus and Its Implications for Management and Conservation
"Poplar is increasingly recognized as an excellent model tree for the study of tree growth and its underlying physiology and genetics. By studying trees of the genus Populus (poplars, cottonwoods, aspens), which in their native ecosystems play a major role in the re-colonization of sites after disturbances, new insights have been gained into plantation culture and the development of improved cultivars. Of the 20 chapters in this publication, editored by an international group of researchers, one section deals with systematics, genetics, genetic manipulation and biotic interactions of Populus, while the other deals with stress response and the physiology of growth and productivity" --
Guide to the Parasites of Fishes of Canada
This guide arranges information on trematode parasites of Canadian fishes by subclass (Aspidogastrea and Digenea), order, superfamily, family, subfamily, and genera. No descriptions are included for individual species because of the large number of taxa involved, but illustrations of members of each genus are provided. Data supplied in the guide include scientific name, synonyms, the position or organ in the fish where the parasite has been reported, hosts, distribution in Canadian waters, authors responsible for the published records of a particular parasite, and comments on the systematics, nomenclature, records, or other aspects of the biology of the parasite. Diagnoses are presented for all taxa down to generic level, and keys are included down to the species level.
A Boy's Cottage Diary, 1904
Fred Dickinson’s diary opens a window on youth and the world of Ontario lakeside cottages at the beginning of the twentieth century.
Science, Agriculture, and Food Security
This book examines the differing concepts of food security and the practicalities, policies, and resources that shape issues of food security. It begins with discussion of the nature of food security, its components, and related concepts such as self-sufficiency and global carrying capacity. It then reviews food consumption patterns in developed nations and developing regions, and discusses the complexities of determining what constitutes an adequate diet, taking into account recommended dietary allowances, variability in food composition, dietary balance and imbalance, diet and disease, nutrient deficiencies, intolerances, and food allergies. The book also reviews divergent concepts of sust...
Water, Science and the Public
This volume is a compilation of current research papers on the aquatic ecosystem of the Miramichi River in New Brunswick. The papers are organized in four sections: historical overview, the physical environment, the biological environment, and evaluating human impacts. Specific topics of the papers include the estuarine structure of the river, hydrology of the drainage basin, plankton, diadromous fish, estuary sediments, forestry impacts, and biological indicators. The volume also includes a summary and selected abstracts from the Miramichi Environmental Science Workshop held in Newcastle in 1994.
Synopsis of the Parasites of Fishes of Canada
Information on the parasites of Canadian fishes published between the years 1978 and 1993, inclusive, is assembled as Parasite-Host and Host-Parasite lists. The 925 named species of parasites are reported on 292 species of Canadian fishes. The Parasite-Host list is organized on a taxonomic basis and identifies for each species its habitat (freshwater, marine, or brackish), site of occurence in its host(s), species host(s), known geographic distribution within Canadian waters, and the published source for each host and localty record. The Host-Parasite list is organized according to the taxonomy of the hosts and is accompanied by data on the known Canadian distribution of the parasites. For both the Parasite-Host and Host-Parasite lists, a "Remarks" section containing explanatory comments concerning systematics, nomenclature, and notes on other specific items is included as warranted. In addition to listing the cited references, as supplentary list of references is included to cover other Canadian literature on fish parasites.
Perspectives on Canadian Marine Fisheries Management
Co-published by: National Research Council of Canada.
Management of Marine Fisheries in Canada
This report describes and evaluates the impact of the major changes in the management of Canada's marine fisheries in recent decades. The report covers the historical and jurisdictional context; biological and economic aspects; objectives of fisheries management; techniques of resources management in general and those used for specific species; managing the common property through allocation of access, limited entry licensing, and individual quotas; the international dimension; the social dimension; habitat management; fisheries enforcement; and fisheries management in the United States, Australia, New Zealand, Norway, Iceland, and the European Community.
Climate Change and Northern Fish Populations
These documents summarize some of the recent studies of the relationships among climate, the aquatic environment, and the dynamics of fish populations. The studies are mostly from the North Pacific ocean, but there are reports of investigations from the North Atlatic Ocean and from fresh water. Various papers include numerous examples of the relationships between fish abundance trends and the environment.
