Seventy-seven monitoring bores were installed at 32 sites as well as a production bore for testing aquifer properties.


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 …


Grass Or Trees? Performance Of Riparian Buffers Under Natural Rainfall Conditions, Australia, Lucy Mckergow, I Prosser, R Grayson, David Weaver, D Heiner Jan 2004

Grass Or Trees? Performance Of Riparian Buffers Under Natural Rainfall Conditions, Australia, Lucy Mckergow, I Prosser, R Grayson, David Weaver, D Heiner

Journal articles

Riparian vegetation can trap sediment and nutrients derived from hillslopes. Most research into the effectiveness of riparian buffers has been experimental and little quantitative data exists on performance under natural field conditions. This study reports on grass and tree buffer performance under natural rainfall conditions in two contrasting Australian environments. Buffers receiving runoff from hillslopes cropped with bananas were monitored over a 4-year period in the wet topics of Far North Queensland (FNQ). Runoff, bedload and suspended loads were measured leaving the crop and leaving 15 m wide dense grass and remnant rainforest riparian buffers. The grass buffer was able …


An Analysis Of Simulated Long-Term Soil Moisture Data For Three Land Uses Under Contrasting Hydroclimatic Conditions In The Northern Great Plains, Rezaul Mamood, Kenneth G. Hubbard Jan 2004

An Analysis Of Simulated Long-Term Soil Moisture Data For Three Land Uses Under Contrasting Hydroclimatic Conditions In The Northern Great Plains, Rezaul Mamood, Kenneth G. Hubbard

High Plains Regional Climate Center: Staff Publications

Soil moisture (SM) plays an important role in land surface and atmosphere interactions. It modifies energy balance near the surface and the rate of water cycling between land and atmosphere. The lack of observed SM data prohibits understanding of SM variations at climate scales under varying land uses. However, with simulation models it is possible to develop a long-term SM dataset and study these issues. In this paper a water balance model is used to provide a quantitative assessment of SM climatologies for three land uses, namely, irrigated corn, rain-fed corn, and grass, grown under three hydroclimatic regimes in Nebraska. …

Kellerberrin Townsite Test Pumping Results 2003, Louise Hopgood Jan 2004

Kellerberrin Townsite Test Pumping Results 2003, Louise Hopgood

Resource management technical reports

A production bore in Kellerberrin, Western Australia, was test pumped for 24 hours in August 2003. Data generated by the pumping were analysed with groundwater monitoring, climate and geological data. Laboratory analyses of water samples from the production bore indicate a low pH and very high levels of salinity, hardness, sodium, chloride, iron, sulphate, aluminium and manganese. This is likely to lead to scaling, blockages, staining and/or corrosion of pumps, pipes and pipe fittings.

Resource management technical reports

A groundwater investigation was initiated in the Buntine-Marchagee Natural Diversity Recovery Catchment 200 kms north-east of Perth, Western Australia in 2002. The investigation aimed to install a regional groundwater monitoring network and characterise the regolith throughout the catchment. Drill site selection was based on establishing a series of transects to enable construction of hydrogeological cross-sections to enhance conceptual understanding of the catchment.


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 …

A Self-Calibrating Palmer Drought Severity Index, Nathan Wells, Steve Goddard, Michael Hayes Jan 2004

A Self-Calibrating Palmer Drought Severity Index, Nathan Wells, Steve Goddard, Michael Hayes

School of Natural Resources: Faculty Publications

The Palmer Drought Severity Index (PDSI) has been used for more than 30 years to quantify the long-term drought conditions for a given location and time. However, a common critique of the PDSI is that the behavior of the index at various locations is inconsistent, making spatial comparisons of PDSI values difficult, if not meaningless.

A self-calibrating Palmer Drought Severity Index (SC-PDSI) is presented and evaluated. The SC-PDSI automatically calibrates the behavior of the index at any location by replacing empirical constants in the index computation with dynamically calculated values. An evaluation of the SC-PDSI at 761 sites within Nebraska, …

Environmental Gradients, Community Boundaries, And Disturbance The Darlingtonia Fens Of Southwestern Oregon, Deborah A. Tolman Jan 2004

Environmental Gradients, Community Boundaries, And Disturbance The Darlingtonia Fens Of Southwestern Oregon, Deborah A. Tolman

Dissertations and Theses

The Darlingtonia fens, found on serpentine soils in southern Oregon, are distinct communities that frequently undergo dramatic changes in size and shape in response to a wide array of environmental factors. Since few systems demonstrate a balance among high water tables, shallow soils, the presence of heavy metals, and limited nutrients, conservative efforts have been made to preserve them. This dissertation investigates the role of fire on nutrient cycling and succession in three separate fens, each a different time since fire. I specifically analyze the spatial distributions of soil properties, the physical and ecological characteristics of ecotones between Jeffrey pine …
