Ogallala Aquifer, Robert F. Diffendal Jr. Jan 2004

Ogallala Aquifer, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

The Ogallala Aquifer, or High Plains Aquifer, is a porous body of complex sediments and sedimentary rock formations that conducts groundwater and yields significant quantities of water to wells and springs. The principal sediments and rocks of the aquifer range in age from 33 million years old to sediments being deposited today, but the majority is less than 12 million-years old. Much of the aquifer is composed of the Ogallala Group or Formation. The dominant sediments in the Ogallala and the other hydrogeologic units in the aquifer are riverand wind-deposited sands. The aquifer underlies about 174,000 square miles of the …


Topographic Maps, Robert F. Diffendal Jr. Jan 2004

Topographic Maps, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Topographic maps show the general configuration of the land surface, including its relief and the position of natural and man-made features. The configuration is shown commonly by contour lines, imaginary lines connecting all points of equal elevation on the earth's surface above or below a datum plane such as mean sea level. When the land slope is steeper the contour lines are closer together. Topographic maps at scales of one inch to a mile or greater (shown as 1:63,360 on the map) are used in many ways. They are particularly important in preparation of various types of geologic maps and …

Empirical Measurement Of Parasite Transmission Between Groups In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown Jan 2004

Empirical Measurement Of Parasite Transmission Between Groups In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

While epidemiological models have suggested that the spread of parasites
and infectious diseases often depends critically on the extent of movement by infected
individuals between populations, there is little empirical information for any organism on
the frequency of between-group parasite transmission or how it varies spatially. The transmission
of parasites between discrete social groups or populations may also help determine
a host’s total parasite or pathogen exposure. We measured the introduction of parasitic bugs
(Oeciacus vicarius) into colonies of Cliff Swallows (Petrochelidon pyrrhonota) by transient
birds from outside each group. The transmission of bugs increased strongly …


Light & Dark: The Hidden Wonders Of Buck Creek, Lee J. Florea Jan 2004

Light & Dark: The Hidden Wonders Of Buck Creek, Lee J. Florea

Earth, Environmental, and Atmospheric Sciences Faculty Publications

As early morning mists rise from the banks of its supple waters, beams of light penetrate the Buck Creek valley illuminating its beauty. While light illuminates most of the land, there are secret places, nestled within the forest where darkness reigns supreme. Places beyond the touch of the sun, beyond the influence of seasons. Here time is measured not in cycles of light but by the flow of water and fall of rock. These are the caves, conduits for water past and present. Nestled in the hills of south-central Kentucky the caves along Buck Creek provide the lifeblood for a …

Teaching For Change: The Leadership In Environmental Education Partnership, Paul Faulstich Jan 2004

Teaching For Change: The Leadership In Environmental Education Partnership, Paul Faulstich

Pitzer Faculty Publications and Research

Humans are transforming earth's landscape from a natural matrix with pockets of civilization to just the opposite. Most of us realize that this pattern is not sustainable. I live and work in Claremont, California, a charming college town in the midst of suburban sprawl. The town has a central village of terminally tasteful, overpriced bungalows nestled in the shade of tall, largely exotic trees. Indeed, most of the landscape of this "city of trees and Ph.D.s" has been imported; only a remnant parcel of coastal sage scrub that the Claremont Colleges have reluctantly preserved remains.


An Inventory And Condition Survey Of The Pilbara Region, Western Australia, A M E Van Vreeswyk, K A. Leighton, A L. Payne, P Hennig Jan 2004

An Inventory And Condition Survey Of The Pilbara Region, Western Australia, A M E Van Vreeswyk, K A. Leighton, A L. Payne, P Hennig

Technical Bulletins

The inventory and condition survey of the Pilbara region, undertaken by the Department of Agriculture, Western Australia between 1995 and 1999, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers about 181 723 km². Seven …


Land For Maine's Future Program: Increasing The Return On A Sound Public Investment, Richard Barringer, Hugh Coxe, Jack Kartez, Catherine Reilly, Jonathan Rubin Jan 2004

Land For Maine's Future Program: Increasing The Return On A Sound Public Investment, Richard Barringer, Hugh Coxe, Jack Kartez, Catherine Reilly, Jonathan Rubin

Economics and Finance

Maine is nowhere a more special place than in the quality of its landscape and the traditions of its land use. Among the mo st privately-owned of all the states, Maine’s natural diversity and beauty combine with its traditions of resource stewardship, open access, and appreciation of nature to distinguish it in the public mind and national imagination. In recent decades, however, these traditions have come under assault from the forces of economic and social change; and the people of Maine have responded. In 1986, Governor Joseph Brennan’s Special Commission on Outdoor Recreation recognized the growing threats to Maine’s natur …


Fire In Southern Appalachians: Fuels, Stand Structure And Oaks, David L. Loftis, Mary A. Arthur, Rex Mann, Jeffrey Lewis Jan 2004

Fire In Southern Appalachians: Fuels, Stand Structure And Oaks, David L. Loftis, Mary A. Arthur, Rex Mann, Jeffrey Lewis

Joint Fire Science Program Research Project Reports

Managers responsible for maintaining the diversity and productivity of Southern Appalachian forests are increasingly turning to prescribed fire as an important management tool in oak dominated forests. The decision to use fire with increasing frequency and spatial extent is based, in part, on an emerging sense of the prehistoric significance of fire in this landscape and its potential to control the proliferation of fire-sensitive competitors in contemporary forests. While it is well documented that fire has been an important ecological force in Southern Appalachian forests for a very long time, there has been little research to demonstrate that prescribed fire …


Response Of Nebraska Sand Hills Natural Vegetation To Drought, Fire, Grazing, And Plant Functional Type Shifts As Simulated By The Century Model, Jennifer Mangan, Jonathan T. Overpeck, Robert S. Webb, Carol Wessman, Alexander Goetz Jan 2004

Response Of Nebraska Sand Hills Natural Vegetation To Drought, Fire, Grazing, And Plant Functional Type Shifts As Simulated By The Century Model, Jennifer Mangan, Jonathan T. Overpeck, Robert S. Webb, Carol Wessman, Alexander Goetz

School of Natural Resources: Faculty Publications

The Nebraska Sand Hills exist in a semi-arid climatic environment and the land surface is grassland growing on sandy soils. These soils have been periodically active throughout the Holocene, but are currently stabilized by the vegetation. However, a shift in climate could cause grassland death and eventual sand dune remobilization. Our studies used the CENTURY nutrient cycling and ecosystem model to investigate the impacts of drought, plant functional type, fire, grazing, and erosion on Nebraska Sand Hills vegetation and dune stability. Fire and grazing alone had little impact on the vegetation, but when combined with mild drought, biomass decreased. Overall …
