Ecology and Conservation of Great Plains Vertebrates

Pages : 329
Book Description
The frontier images of America embrace endless horizons, majestic herds of native ungulates, and romanticized life-styles of nomadie peoples. The images were mere reflections of vertebrates living in harmony in an ecosystem driven by the unpre dictable local and regional effects of drought, frre, and grazing. Those effects, often referred to as ecological "disturbanees," are rather the driving forces on which species depended to create the spatial and temporal heterogeneity that favored ecological prerequisites for survival. Alandscape viewed by European descendants as monotony interrupted only by extremes in weather and commonly referred to as the "Great American Desert," this country was to be rushed through and cursed, a barrier that hindered access to the deep soils of the Oregon country, the rich minerals of California and Colorado, and the religious freedom sought in Utah. Those who stayed (for lack of resources or stamina) spent a century trying to moderate the ecological dynamics of Great Plains prairies by suppressing fires, planting trees and exotic grasses, poisoning rodents, diverting waters, and homogenizing the dynamies of grazing with endless fences-all creating bound an otherwise boundless vista. aries in Historically, travelers and settlers referred to the area of tallgrasses along the western edge of the deciduous forest and extending midway across Kansas as the "True Prairie. " The grasses thlnned and became shorter to the west, an area known then as the Great Plains.
Ownership and Productivity of Marine Fishery Resources

Book Description
At a time when the health and future viability of the world's ocean is becoming a subject of growing social, political and ecological concern, Elmer A. Keen has offered a timely and thought provoking analysis of the present use of the marine fishery resources. To permit marine fisheries to remain viable, Keen argues that their current management as common resources must be changed and suggests a paradigm by which a top-to-bottom reformation of the industry to one based on ownership of the resource, coupled with profit incentives for the resource owner, might be accomplished. Revisionary when new, this book is now considered near the mainstream of thinking about the management of marine fisheries and the conservation of this important resource.

Research Trends on Fish & Fisheries in Mountain Waters of Eastern Himalayan Region
Author: Debangshu Narayan Das, Santoshkumar Abujam, Achom Darshan SinghPublisher: Notion Press
ISBN: 1645468437
Category : Nature
Languages : en
Pages : 342
Book Description
This book contains a total of 25 unpublished research articles. In this edition, we have kept parity with each other’s outcomes, concisely in a unique style to depict the trends of research in the mountain fishery sector. We have also appended a list of contributors at the end of the book. The strategies observed in fisheries and aquaculture developments in the mountain waters clearly reveal that the on-going dimensions are nothing but broad ecosystem-based approached where both subsistence and commercial expansion of the systems could be possible. The research trend also directs that several fishery components, like ornamental fisheries, recreational fisheries, integrated fish farming, freshwater crab fishery, shellfish aquaculture, etc., exist. They may also be strengthened in mountain waters to improve the economic status of the mountain regions. Thus for exploiting huge mountain aqua-resources, Arunachal Pradesh targets the ecosystem-based approach of raising native mahseers, like Tor tor, Tor putitora, Neolissochilus hexagonolepis, and exotic species of trout in its mountain waters as a preliminary endevour.
