Development, Sustainability, And The Deforestation Of Samoa, Paul Shankman
Development, Sustainability, And The Deforestation Of Samoa, Paul Shankman
Pacific Studies
The forests of Samoa (formerly Western Samoa) are rapidly disappearing. This article reviews the history of Samoan deforestation, particularly during the last four decades, in the context of ideas about development and sustainability. It also examines the role of village agriculturalists in the process of deforestation. Recent economic, technological, and organizational changes have increased village agricultural expansion and, consequently, deforestation.
Legislating A Sustainable Land Ethic For New Zealand, Michèle D. Dominy
Legislating A Sustainable Land Ethic For New Zealand, Michèle D. Dominy
Pacific Studies
This article explores competing discourses of sustainability in New Zealand’s South Island. As active resource managers, high-country pastoralists’ conception of “country” contests predominant reductive and binary models of production/ conservation and economic resource/visual resource and suggests a more complicated dynamic between scientific and cultural paradigms of sustainability than has been acknowledged. This dynamic is captured in the internationally driven top-down concept of equitable sustainable land management with a dual commitment to both cultural and ecological diversity as defined locally, formulated as part of the United Nations Rio Declaration of 1992, agenda 21, chapter 13. I examine an emergent high-country “land …
The Effect Of Divalent Cations On The Prophenoloxidase Enzyme Cascade Activity In The Freshwater Crayfish Cambarus Latimanus, Hans Skailand Eikaas
The Effect Of Divalent Cations On The Prophenoloxidase Enzyme Cascade Activity In The Freshwater Crayfish Cambarus Latimanus, Hans Skailand Eikaas
Theses and Dissertations
The effect of divalent cations such as cadmium, calcium, copper, lead and magnesium upon the prophenoloxidase system (proPO) was studied in hemocytes of the crayfish Cambarus latimanus. It was demonstrated that cadmium, calcium, copper and lead increased proPO activity significantly, whereas magnesium had no statistically significant effect on the system. Also, the molecular weight of the proPO enzyme was estimated using SDS-PAGE and found to be approximately 76 kDa.
Production Of The Subtropical Seagrass, Halodule Wrightii Aschers., In Lower Laguna Madre, Texas, Joseph L. Kowalski
Production Of The Subtropical Seagrass, Halodule Wrightii Aschers., In Lower Laguna Madre, Texas, Joseph L. Kowalski
Theses and Dissertations - UTB/UTPA
The autecology of shoal grass, Halodule wrightii Aschers., was studied at 1.2 m depth from June 1995 to February 1997 in Lower Laguna Madre (LLM), Texas. Halodule wrightii in LLM received about 47% surface irradiance, but otherwise displayed lower growth rates and biomass in nutrient-poor rhizosphere and water-column environments compared to H. wrightii populations in other Texas estuaries. High tissue N content and low C:N ratios belied low growth dynamics. Halodule wrightii in LLM is probably nutrient limited. A high nutrient demand by H. wrightii in a nutrient-poor environment may explain, in part, its gradual displacement by Thalassia testudinum and …
Evaluation Of Sampling Methodologies For Assessing Fish Species Richness In Ridge And Valley Streams In Chattanooga, Tennessee, Evan Robertson Crews
Evaluation Of Sampling Methodologies For Assessing Fish Species Richness In Ridge And Valley Streams In Chattanooga, Tennessee, Evan Robertson Crews
Masters Theses and Doctoral Dissertations
I evaluated the adequacy of different electrofishing approaches for estimating species richness in small Ridge and Valley streams. My study objectives were to determine the effects of the sampling season, reach length, habitat sequences surveyed, and sampling intensity on estimates of fish species richness. Fish assemblages were sampled at 18 sites across five streams in the Chattanooga, Tennessee area, May-June (spring) and July-August (summer) 1998. Reach lengths ranged from 103 to 278 m (30 to 61 times the mean stream width [MSW]). At each site, fish were collected using one or two backpack electrofishers within habitat-specific enclosures (riflle-run or pool). …
Effects Of Watershed Land Use On The Benthic Macroinvertebrate Assemblages In Ridge And Valley Streams In Chattanooga, Tennessee, Paul Leiper Freeman
Effects Of Watershed Land Use On The Benthic Macroinvertebrate Assemblages In Ridge And Valley Streams In Chattanooga, Tennessee, Paul Leiper Freeman
Masters Theses and Doctoral Dissertations
A total of 20 sites in five Ridge and Valley streams located in Chattanooga, Tennessee were sampled May 8, 1998 to June 18, 1998 using quantitative and qualitative macroinvertebrate sampling techniques. All streams sampled were part of the Tennessee River drainage system and eventually contribute to Nickajack Reservoir. The 20 sites were second to fourth order streams with drainage areas of 3.8 to 46.9 (km2) and elevations of 195 to 232 (m). Sites with different percentages of agricultural, urbanized and forested land-use were selected to best evaluate the resulting impacts of urbanization and other anthropogenic activities on the invertebrate community …
Wildlife-Caused Losses For Producers Of Channel Catfish Ictalurus Punctatus In 1996, Alice P. Wywialowski
Wildlife-Caused Losses For Producers Of Channel Catfish Ictalurus Punctatus In 1996, Alice P. Wywialowski
United States Department of Agriculture Wildlife Services: Staff Publications
The National Agricultural Statistics Service surveyed by telephone and mail in January and February 1997 all known producers of channel catfish Ictalurus punctatus to acquire current information about wildlife-caused losses in calendar year 1996. Many producers tried to prevent wildlife-caused losses of their catfish by shooting (57%), vehicle patrol (55%), or frightening (36%), at an estimated cost of >$5 million. Yet, 69% of catfish produces cited some wildlife-caused losses. Birds were most frequently cited as a cause of losses, and double-crested cormorants Phalacrocorax auritus was the species cited most frequently (53%). The next most frequently cited bids were herons Ardea …
Trace-Level Determination Of Fluorescently Labeled Phenoxy Acid Herbicides And The Study Of Their Crop Uptake And Soil Accumulation, Noura Saeed Al Nuaimi
Trace-Level Determination Of Fluorescently Labeled Phenoxy Acid Herbicides And The Study Of Their Crop Uptake And Soil Accumulation, Noura Saeed Al Nuaimi
Theses
A challenging problem facing the determination of phenoxy acid herbicides in samples is their low UV absorptivity and the interference associated with the matrix in which these analytes exist. This thesis is concerned with improving the detection limits of this group of herbicid as well as reduce or eliminate interference associated with the sample matrix.
Native phenoxy acid herbicides could be analyzed by high performance liquid chromatography (HPLC) with ultraviolet detection. Phenoxy herbicides were analyzed by HPLC employing a gradient conditions that allowed baseline resolution of all analytes used in this study in approximately 20 min. However, the average detection …

Reciprocal Transplantation Of The Desert Soil Crust: Can It Be Done?, Christina D. Cole
UNLV Theses, Dissertations, Professional Papers, and Capstones
A 100 meter X 100 meter study site was chosen at White Rock Springs in Red Rock Canyon National Conservation Area, Nevada. To examine Syntrichia caninervis, a desert crustal moss, reciprocal transplantations (20 mm and 40 mm diameter cores) were performed between shaded to shaded, exposed to exposed, and shaded to exposed microsites to determine if it was possible to transplant the study organism with reasonable survivorship. Transplants were inspected following rain events for percent hydration, number of dead stems, and change in percent cover. Data indicated that there was a low mortality rate of S. caninervis stems, and few …

Summary Of Historical Information Relevant To The Hydrobiological Monitoring Of The Lower Peace River And Upper Charlotte Harbor Estuarine System, Pbs&J, Inc.
Reports
This review is focused on the relationship between plankton communities in Upper Charlotte Harbor and changes in freshwater flows that might result from Peace River water withdrawals. There are lour mechanisms by which freshwater withdrawals from the Peace River could influence plankton communities within the Lower Peace River and Upper Charlotte Harbor estuarine system. The first mechanism would involve removing enough water to cause the geographical location of mean isohalines to shift. If the locations shifted enough that isohalines lie over areas with different physical or biological habitats than the areas currently occupied, a significant biological effect might result. The …
