Applications Of Geographic Information Systems, Remote-Sensing, And A Landscape Ecology Approach To Biodiversity Conservation In The Western Ghats, Shaily Menon, Kamaljit S. Bawa

Shaily Menon

The mountains along the west coast of peninsular India, the Western Ghats, constitute one of the unique biological regions of the world. Rapidly occurring land-cover and land-use change in the Western Ghats has serious implications for the biodiversity of the region. Both landscape changes as well as the distribution of biodiversity are phenomena with strong spatial correlates. Recent developments in remote-sensing technology and Geographic Information Systems (GIS) allow the use of a landscape ecology and spatial analysis approach to the problem of deforestation and biodiversity conservation in the Western Ghats. Applications of this approach include analyses of land-cover and land-use …

Coyote Food Habits At Desoto National Wildlife Refuge, Nebraska, Jeffrey J. Huebschman, Scott E. Hygnstrom, Joseph A. Gubanyi

School of Natural Resources: Faculty Publications

Coyote (Canis latrans) food habits were detennined from 490 scats collected from October 1994 to October 1995 at DeSoto National Wildlife Refuge (DNWR), along the Nebraska/Iowa border. Mammals occurred most frequently, as measured by percent-of-scats (POS) , followed by vegetation, birds, and invertebrates. Mammals also constituted the largest portion of coyote diet, as determined by fresh weight correction factors. Within the mammalian category, white-tailed deer (Odocoileus virginianus) occurred most frequently and constituted the largest portion of diet by fresh weight correction factors. White-tailed deer occurrence and importance in diet peaked in June, which corresponds to the …

Artificial Recharge In The Las Vegas Valley: An Operational History, Michael Johnson, Erin Cole, Kay Brothers, Las Vegas Valley Water District

Publications (WR)

Artificially recharging the Las Vegas Valley (Valley) ground-water system with treated Colorado River water is one water resource management option employed by the Las Vegas Valley Water District (District) to help meet future long-term and short-term peak water demands. The District began operation of an artificial ground-water recharge program in 1988 in order to bank water for future use and to slow declining water levels. Artificial recharge occurs in the winter months, typically from October to May, when there is excess capacity in the Southern Nevada Water System (SNWS), currently a 400 Million Gallon per Day (MGD) treatment and transmission …

Effects Of Flow Augmentation On Channel Morphology And Riparian Vegetation In The Upper Arkansas River Basin, Colorado, Dewitt S. Dominick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined historic change of riparian plant communities and fluvial geomorphic response of gravel-bedded streams and their floodplains to over 50 years of hydrologic disturbance. Four tributary basins of the Arkansas River were analyzed. Lake Creek, Clear Creek, and Cottonwood Creek are drainages similar in area, physiography, and vegetation composition. However, Lake Creek may receive an instantaneous discharge of approximately 28 m3sec^-1 from the Twin Lakes tunnel, over three times the normal flow of the stream during spring runoff. By contrast, Clear Creek and Cottonwood Creek, nonaugmented streams, were used as controls to compare the historic and present …

Las Vegas Wash Water Quality Monitoring Program: 1996 Report Of Findings, Richard A. Roline, James J. Sartoris, U.S. Bureau Of Reclamation, U.S. Geological Survey

Publications (WR)

Las Vegas Wash, a natural wash east of the city of Las Vegas, Nevada, carries stormwater, groundwater drainage, and sewage effluent from three sewage treatment plants to Lake Mead. The Wash provides nearly the only surface water outlet for the entire 2,193 mi² of Las Vegas Valley. A drainage area of 1,586 mi² contributes directly to the Wash through surface flow which is channeled to Las Vegas Bay of Lake Mead, while drainage of the remaining 607 mi² is presumably subsurface and may drain toward Las Vegas Wash.

In the 1930's and 1940's, sewage treatment plants were …

JOHN WgW Volume 7, Number 2 NEW MUIR Spring 1997 X I 4 J^,AN EPISODE IN THE YOSEMITE: by Frank E. Buske copyright @ 1989,1991, by Frank E. Buske (Editor's note: Dr. Frank Buske, emeritus professor and former Chair of the English Department at the University of Alaska, Fairbanks, now lives in Tucson, Arizona. This paper was presented at the 1990 John Muir Conference at UOP, and is published here, along with letters from a private collection, with the author's permission.) ('•< Muir spent the winter of 1873-75 at the McChesney home in land, having come down from his beloved mountains to spend time putting into words some of the observations he had made • ■ nig the trees and the glaciers and on the ■ - les. Mrs. Jeanne Carr and others of his I «ls had, for a long time, been * •imaging him to do more writing; they HHgested that there was a market for his j I les and a need for him to set down his ilf|overies while they were still fresh in his mind. Mrs. McChesney, in a later reminiscence, described Muir as "dressed gi»iei ally in what we call now negligee, i.e., he wore a blue flannel shirt, but was never : without a sprig of some green plant as an-S*0 jjpment." Muir's apparel would be appropriate for ij§krnd of life he most enjoyed. He disliked lifting to dress for any formal occasion and hied to avoid any social gathering that would HHuire clothing and behavior that were not comfortable to him. Although he had uently written of his loneliness, sped1 w.f t enviously about his relatives and ids who had married and were raising families, he seems to made no effort to alter his own bachelor status during that Winter in the Bay Area. Mrs. J "• ' Carr The subject of John Muir and his relationship with women is interesting to ponder, and is a topic that has received a good deal of attention and even more misinformed speculation. Some verses that he wrote before this time, highly critical of young women, their appearance and the way they dressed, prompted his friend, Bradley Brown, to write the eighteen-year old Muir, "Excuse me, John, but perhaps unreciprocated love was the cause of your rhyming against the sweet little creatures. To love is painful, that is true. Not to love is painful, too. But oh! It gives the greatest pain to love and not to be loved again." The subject of Muir's poem may well have been imaginary but Brown's observations can certainly be considered prescient. At twenty-two, in Prairie du Chien, Wisconsin, working with ice-boat inventor Wiard, John Muir wrote his brother, David, telling him of the people he was meeting. David, very much a ladies' man, replied, "I would like very well to hear that piano and Miss E.P. (excuse me, John) playing on it." Miss E.P. was, of course, Emily Pelton, niece of the proprietors of the Mandell House where Muir was living. In December of that same year, John Muir wrote his sister, Sarah, and her husband, David Galloway, of an occasion which shows a rather vivid picture of his social skills: UNIVERSITY OR page 1 (continued on page 3) PACIFIC

Impacts Of Air Temperature Variations On The Boro Rice Phenology In Bangladesh: Implications For Irrigation Requirements, Rezaul Mahmood

School of Natural Resources: Faculty Publications

Air temperature significantly affects crop phenology. Numerous experiments have shown that prevailing air temperature determines the length of crop growth stages. Irrigation field requirements depend on the length of the crop growth stages. In the present study, a physically based parametric model, YIELD, has been applied to estimate the impacts of fluctuating air temperature (due to inter-annual climatic variability and global warming) on evapotranspiration water requirements and the length of growth stages of the irrigated boro rice in Bangladesh. The YIELD model is crop specific and crop-growth-stage specific which is a compromise between area-specific regression models and complex crop growth …

Composting Landscape Waste From The University Of Nevada, Las Vegas, K. Jill Hammond

UNLV Theses, Dissertations, Professional Papers, and Capstones

The University of Nevada, Las Vegas is a major producer of organic waste in the Las Vegas Valley. Composting landscape wastes is one way to reduce both landfill dumping and fertilizer costs for the university. It is also an environmentally friendly means of curbing a nationwide problem: unnecessary use of landfill space. Three sites within Clark County were analyzed for the feasibility of composting: Frenchman Mountain, UNLV Campus, and Boulder City Landfill. Using cost analysis, water availability, and other factors to analyze each site, Boulder City Landfill appears to be the best place to house UNLV's composting operation. Composting in …

Effects Of Seagrass Biology On Water Quality In Shallow Regions Of The Lower Chesapeake Bay : Final Report, Kenneth A. Moore

Reports

The changes in water quality within shallow water regions of the lower Chesapake Bay was compared seasonally from permanent stations located along transects across vegetated and unvegetated sites in shoal regions of the lower Chesapeake Bay. The effect of the seagrass bed on conditions inside compared to outside of the bed varied seasonally and could be related to bed biomass and develoment. During spring (April-June) the rapidly growing seagrass bed was a sink for nutrients, suspended inorganic particles and phytoplankton, while during the summer, as bed dieback progressed, resuspension and release of nutrients were observed. Reductions in suspended particle concentrations …

Late Holocene Eolian Activity In The Mineralogically Mature Nebraska Sand Hills, Daniel R. Muhs, Thomas W. Stafford Jr., James B. Swinehart, Scott D. Cowherd, Shannon A. Mahan, Charles A. Bush, Richard F. Madole, Paula B. Maat

School of Natural Resources: Faculty Publications

The age of sand dunes in the Nebraska Sand Hills has been controversial, with some investigators suggesting a full glacial age and others suggesting that they were last active in the late Holocene. New accelerator mass spectrometry radiocarbon ages of unaltered bison bones and organic rich sediments suggest that eolian sand deposition occurred at least twice in the past 3000 ^I4C yr B.P. in three widely separated localities and as many as three times in the past 800 ¹⁴C yr at three other localities. These late Holocene episodes of eolian activity are probably the result of droughts more …

The reflectance spectra of wastewater effluent were investigated in order to develop algorithms for remote estimation of wastewater quality expressed as chlorophyll-α, bacteriochlorophyll-α, non-organic and total suspended matter concentrations. Reflectance height at 720 nm and an area above the base line from 670 to 950 …

Ecological Water Treatment System For Removal Of Phosphorus And Nitrogen From Polluted Water, Ray W. Drenner, Donald J. Day, Stacy J. Basham, J. Durward Smith, Susan I. Jensen

School of Natural Resources: Faculty Publications

We propose that phosphorus and nitrogen can be removed from polluted water using an ecological water treatment system consisting of periphyton and fish. In the proposed system, polluted water flows through a series of vessels, and the nutrients are taken up by periphyton growing on porous screens. Algal-grazing fish feed on the periphyton and either assimilate or egest the nutrients in mucus-bound feces that settle from the water into a sediment trap. Both the fish and their feces can be harvested as nutrient sinks. In this study we examined the effects of an algal-grazing cichlid (Tilapia mossambica) and …

Habitat Area Requirements Of Prairie Wetland Birds In Eastern South Dakota, David E. Naugle

Electronic Theses and Dissertations

The influence of area and vegetation structure on bird use of 830 semipermanent and seasonal wetlands (0.2-217.5 ha) was studied to evaluate vegetative needs and habitat area requirements of 20 breeding wetland bird species in eastern South Dakota in 1995-1996. Vegetative preferences of species varied, but most waterfowl and nongame species occur e4i more frequently in wetlands with intermediate cover-to-water ratios whereas five over-water nesting or secretive nongame species were found in wetlands with greater coverage of emergent vegetation. The occurrence of four nongame species that depend on vegetative structure to support the weight of their over-water nests also was …

Eastern South Dakota Wetlands, Rex R. Johnson, Kenneth F. Higgins, Michael L. Kjellsen, Charles R. Elliot

Natural Resource Management Faculty Books

Diverse and extensive wetland resources have always been familiar parts of the landscape to farmers, hunters, and residents of eastern South Dakota. The journals and oral histories of adventurers, trappers, and natives and immigrants reveal how wetlands shaped the wildlife and the people who lived on and modified the land to meet their own needs. The history of South Dakota wetlands parallels the history and interactions of people and wetlands elsewhere in North America and the world. This interaction can best be characterized as constant conflict. Driven primarily by economics, farmers the world over expended tremendous energy to "reclaim" and …

The mere mention of the word "wetland" in coffee shops and other gathering places on the prairies today brings out emotions and opinions that run the gamut from saving them all to draining them all. To some people, what we do with wetlands has been, and still is, a personal choice, a matter of exercising individual rights on private property. To others, wetlands are community resources that provide values that touch all of society. They contend that what is done to and about wetlands is a community decision regardless of ownership. Herein lies the controversy we have experienced over wetlands …
