For Whom Is The Rural Economy Resilient? Initial Effects Of Drought In Western Sudan, Leslie C. Gray, Michael Kevane

Economics

This discussion piece addresses two recent debates: entitlement theory and the resilience of rural systems. The authors find that in western Sudan entitlement theory provides a specific and useful framework for understanding the nature of the crisis confronting the society. Arguments about the resilience of rural systems, however, need to be more closely examined and will depend on site-specific factors. The rural economy and society of western Sudan were not found to be resilient.

Field Manual For The Identification Of Selected North American Freshwater Fish By Fillets And Scales, David W. Oates, Lisa M. Krings, Karen L. Ditz

Other Publications in Wildlife Management

This manual is designed for use in the field to help conservation officers identify fish that have been filleted or skinned. Many North American freshwater gamefish and those caught by commercial fishermen are included. Our goal was to collect six fish of each species for measurement purposes. Several states and provinces including Alaska, Colorado, Florida, Idaho, Iowa, Michigan, Missouri, Nebraska, New York, Ontario, Saskatchewan, Texas, Virginia, Washington, Washington D.C., Wisconsin and Wyoming furnished samples. Fish may vary from location to location; these differences were not corrected for in this manual.

For identification of fish, we will first examine fillets. Fish …

Preserves At Risk: An Investigation Of Resource Management Strategies, Implications And Opportunities, R. J. Lilieholm

Elusive Documents

Human activities already threaten the globe's physical and biological systems. Worldwide, species extinction rates are estimated to be one thousand times what they would be in the absence of human activity (Wilson 1988). Raven (1988) estimates that 25% of the world's plant and animal species existing in 1985 may be extinct by 2015, with most extinctions occurring in tropical regions. While these extinction rates are staggering, global warming would greatly accelerate extinction rates that some scientists believe may already exceed those accompanying the decline of the dinosaurs 65 million years ago (Wolf 1987).

Development Of A Hypermedia Database For The Elementary Classroom, Jane Pattison Brown

All Graduate Projects

A hypermedia database including selected flora and fauna in Kittitas County, Washington, was developed using HyperCard software for researching information about 400+ species. students had the opportunity to use the database in school libraries and in the author's fifth-grade classroom. The database cards accessed videodisc images where available. On the basis of limited study to date, it appears that when studying the environment, student learning was enhanced by the use of database material created by the author.

Iceberg Severity Off The Canadian East Coast (An Analysis Of The 1991 Iceberg Season), Jerome Edward Salloum

Theses and Dissertations (Comprehensive)

The 1991 iceberg season on the Grand Banks was the second most severe on record. Over a 218-day period, a total of 2002 icebergs traversed latitude 48°N. Percentages of sightings involving medium and large icebergs greatly exceeded normal values. Thus, the season was mxtstanding, not only in terms of flux numbers, but in terms of total ice mass delivered. Assuming that this flux anomaly is the product of more efficient advection and less efficient ablation and notzsome sudden surge in upstream berg production, the study investigates various atmospheric and sea surface conditions as contributing factors to a near record iceberg …

The Potential Environmental Consequences Of Utilizing Sewage Sludge As Fertilizer On Agricultural Lands: A Case Study Of The Region Of Waterloo (Ontario), Benjamin C. Mohabir

Theses and Dissertations (Comprehensive)

With the advent of increased volumes of liquid sewage sludge being produced in the world annually, means of disposal and recycling have become a serious issue. The disposal of sludge onto agricultural lands has raised concern regarding its environmental implications. The concern stems from the presence of toxic substances often found in sludge which can be harmful to the environment. The sludge utilization programme in the Regional Municipality of Waterloo has shortcomings in the areas of site evaluation and monitoring, and setting an application agenda tied in with a weather forecasting system. These shortcomings combined with the physical characteristics of …

Remote Detection Of Coral 'Bleaching' Using Pulsed-Laser Fluorescence Spectroscopy, J. T. Hardy, F. E. Hoge, J. K. Yungel, Richard E. Dodge

Marine & Environmental Sciences Faculty Articles

Despite their biological and economic importance coral reefs are increasingly threatened by human activities. Recently, 'bleaching' of reefs, i.e. loss of photosynthetic pigmentation, has occurred at numerous globally-distributed sites. A number of environmental stressors, including increased water temperature, can induce bleaching. Several investigators have suggested that the widespread occurrence of coral bleaching represents an early warning signal of global greenhouse warming. Regardless of the cause, the extent of coral bleaching, both regionally and globally, needs to be documented and monitored. We conducted laboratory studies to evaluate the potential of using remotely-sensed laser-induced fluorescence to monitor coral pigmentation. Five species of …

Lake Trout Spawning In Lake Tahoe: Egg Incubation In Deepwater Macrophyte Beds, D. A. Beauchamp, B. C. Allen, R. C. Richards, Wayne A. Wurtsbaugh, C. R. Goldman

Watershed Sciences Faculty Publications

Although most populations of lake trout Salvelinus namaycush spawn over rocky shoals, use of these substrates by lake trout has not yet been found in Lake Tahoe. Large cobble substrate exists at depths less than 20 m, and steep, fractured, rocky substrate can be found in isolated areas from the surface down to at least 100 m, but no evidence of spawning activity in these areas has been found. Instead, at least a portion of the population spawns on deepwater mounds (40–60 m deep) over beds of the macrophyte Chara delicatula. This is the first known report of lake trout …

Phytoplankton Community Abundance And Diversity In Dardanelle Reservoir, Arkansas, 1981-1990, John D. Rickett, Robert L. Watson

Journal of the Arkansas Academy of Science

Phytoplankton samples were collected quarterly from 1981-1990 at five stations representing discharge water from Arkansas Nuclear One, a nuclear generating station, and four "control" or "dispersal evaluation" stations. Seventy-five taxa representing five divisions were identified and enumerated. Community structure was evaluated using abundances, number of taxa, and Margalef's Richness, Shannon's Heterogeneity and Pielou's Evenness indices. No long-term trends were identified, but the beginning of cyclic variations, with a 7-year periodicity, in abundance, number of taxa, and Shannon's and Pielou's indices were apparent. Margalef's index values were constant during most of the study period. For all samples, t-tests and Mann-Whitney U …

Argonne National Laboratory, a U.S. Department of Energy facility that is operated by the University of Chicago and located southwest of Chicago, Illinois, has proposed a collaborative effort by the United States and Poland to conduct applied research on energy and environmental topics of common interest. Through this collaboration, evaluative studies on energy and environmental assessment issues could be developed and implemented by Argonne and one or more sister institutions in Poland, which could lead to active research, development, and demonstration joint activities. The objective of this initiative is to produce strategies and options for review by Poland's decision makers …

The Energy Crisis: The Case Of The Economic Community Of West African States (Ecowas), With Special Reference To Nigeria, Ghana And Burkina Faso, Francis Bliss Lagbo

Theses and Dissertations (Comprehensive)

The energy crisis of West African countries has assumed major importance over the past few decades. The oil price increases of the 1970s have posed innumerable problems to these countries. But that is hardly the entire story. The vegetation cover of most places have been stripped so bare that people must walk for hours to find the day's supply of firewood, the traditional energy source. Doing something about the problem involves, first of all, understanding what the situation really is. This study provides an analysis of the spatial, sectoral and social inequalities in energy production and consumption in BCOWAS. Scrutiny …

Hydrologic Investigations Of Meltwaters Draining Gornergletscher And Findelengletscher, Switzerland Using Hydrochemistry And Isotopic Analyses, Robert A. Metcalfe

Theses and Dissertations (Comprehensive)

The purpose of this thesis is to investigate the hydrological dynamics of Gornerglestcher and Findelengletscher, Switzerland by performing hydrochemical analyses on the bulk runoff exiting the portal of these two alpine glaciers. The hydrochemical analyses utilized electrical conductivity, as a surrogate for total dissolved solids, to determine the flow of routing of the bulk runoff (englacial or subglacial as defined by Collins, 1979b) and 8^18O to determine the contributions of pre-event and event water to bulk runoff during precipitation events. The pre-event water was defined as a combination of snow meltwater, ice meltwater and groundwater as these flow components could …

The primary objectives were to: examine the types of external threats and their implications to ecosystems in the selected parks; examine the responses of park managers to prevent changes in ecological integrity; determine whether or not the management techniques of park managers are rehabilitating and/or preventing ecological change induced by external threats: and make an initial comparison of national …

Investigation Of Hydrometeorological Relationships, Pasu Glacier Basin, Northern Pakistan, Bob Boyce

Theses and Dissertations (Comprehensive)

Records of air temperature, global radiation and discharge from the Pasu Glacier basin in the Upper Indus River Basin have been examined with a view to developing a modest understanding of the simple physically based processes in action within this globally extreme mountainous region. Some glaciological data are also reported but in a preliminary manner. Relationships between air temperature characteristics, global radiation and discharge were investigated using correlation techniques. Daily average air temperatures recorded at the highest meteorological station, Parundas (4200m), provide the strongest degree of association with discharge. The data shows that this highly glacierised Karakoram basin exhibits similar …

The Role Of The Vadose Zone In The Generation Of Runoff From A Headwater Basin In The Canadian Shield, Robert Alex Maclean

Theses and Dissertations (Comprehensive)

Hydrological processes occurring within the vadose zone, especially in heterogeneous soils and tills typical of the Canadian shield, are not well understood. This research investigates the importance of the vadose zone in a small headwater basin (Harp 4-21) in the Canadian shield with respect to the generation of stream runoff quantity and quality during episodic rainfall and snowmelt events. The study focused specifically on: firstly the effect of variable antecedent moisture conditions on water-table and stream response, secondly, the significance of the stored vadose water in water extracted from a rising water-table, and thirdly the significance of preferential flowpathways in …

Zooplankton Community Abundance And Diversity In Dardanelle Reservoir, Arkansas, 1981-1990, John D. Rickett, Robert L. Watson

Journal of the Arkansas Academy of Science

Zooplankton samples were collected quarterly from five stations representing the discharge bay and four "control" or "dispersing impact" stations. Rotifers dominated all samples numerically and by the number of taxa. All major groups (Rotifera, Cladocera, Copepoda, and Protozoa) exhibited greatest abundances during the summer. Quarterly variations in abundance and number of taxa were documented. Except for an increase in taxonomic analysis detail between 1981 and 1984 resulting in several more taxa added to the list, no long-term increases, declines or repeating cycles were apparent. Margalef's Richness Index reflected this change and showed a long-term increase with evidence of a 5- …
