Management Of The Houtman Abrolhos System., Kim Nardi, Abrolhos Islands Management Advisory Committee
Fisheries Management Papers
The Abrolhos System is the Houtman Abrolhos Islands and adjoing State Territorial Waters. It is an important part of the Western Australian environment. Has major significance in conservation of flora and fauna and also in geological terms. The waters adjoining State Territorial Waters contain some of the most highly valued marine systems in the State. These include sites of historical shipwrecks in Australia. The are of great interest to visitors and support a relatively small but growing recreation and tourism industy.
The area is integral to the Western rock lobster fishery, which is that State's premier primary industries. The Abrolhos …

Fisheries Research Report No. 112 - Final Report, Frdc Project 94/075: Enhancement Of Yabby Production From Western Australian Farm Dams, Fisheries Western Australia, Fisheries Research And Development Corporation
Fisheries Research Reports
Farmers receive higher prices per kilo for large yabbies. Yabby farmers have reported that the majority of yabbies trapped from farm dams are below market size (< 30 g) and therefore of no economic value. In addition, farmers also report that while dams produce large yabbies when first harvested, after a number of years the proportion of large animals gradually decreases.
To identify why yabbies in farm dams stunted and how farmers could increase the size of small yabbies the project had three main experimental areas.
Research station experiments: A field research station consisting of 25 ponds was constructed for running replicated, randomised and reproducible experiments, with controls, in an environment that simulated farm dams. In addition, these ponds were large enough to provide an adequate sample number of yabbies at realistic industry stocking …
Review Of People And The Land Through Time: Linking Ecology And History By Emily W. B. Russell, Emily Greenwald
Review Of People And The Land Through Time: Linking Ecology And History By Emily W. B. Russell, Emily Greenwald
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
While some environmental historians have used the insights of the natural sciences in their historical work, Emily Russell, offering a scientist's perspective, challenges ecologists to incorporate historians' methods and insights into their studies. In People and the Land through Time, Russell outlines working principles for the "historical ecologist," a scholar who traces past human impacts on particular ecosystems. She makes it clear that her emphasis is on ecological systems rather than humans, but argues that ecosystems can't be fully understood without accounting for how human actions have affected them.
The book provides an introduction to methods and a variety …

Directory Of Water Related Courses Offered At Colleges And Universities In Arkansas As Of November 1998, Kenneth F. Steele
Directory Of Water Related Courses Offered At Colleges And Universities In Arkansas As Of November 1998, Kenneth F. Steele
Arkansas Water Resources Center Technical Reports
This publication lists the water and water-related courses at several universities and colleges in Arkansas as reported during the Fall of 1 998. It is anticipated that users of this directory will extend beyond college students, and will include professionals seeking continuing education, and professors desiring to exchange Information on courses. This directory is not an "absolute" source of water and water-related courses because all of the higher learning Institutions In Arkansas are not listed, and, secondly, because the definition of "water and water-related" varies from institution to institution. None-the-less this directory provides a very valuable and impressive reference on …

Design Of An Epidemiologic Study Of Drinking Water Arsenic Exposure And Skin And Bladder Cancer Risk In A U.S. Population, Margaret R. Karagas, Tor D. Tosteson, Joel Blum, J Steven Morris, John A. Baron, Bjoern Klaue
Dartmouth Scholarship
Ingestion of arsenic-contaminated drinking water is associated with an increased risk of several cancers, including skin and bladder malignancies; but it is not yet clear whether such adverse effects are present at levels to which the U.S. population is exposed. In New Hampshire, detectable levels of arsenic have been reported in drinking water supplies throughout the state. Therefore, we have begun a population-based epidemiologic case-control study in which residents of New Hampshire diagnosed with primary squamous cell (n = 900) and basal cell (n = 1200) skin cancers are being selected from a special statewide skin cancer incidence survey; patients …

Winter Macroinvertebrate Communities In Two Montane Wyoming Streams, Christopher M. Pennuto, Frank Denoyelles Jr., Mark A. Conrad, Frank A. Vertucci, Sharon L. Dewey
Great Basin Naturalist
Macroinvertebrate communities were examined on 4 winter dates over a 4-yr period in 2 high-altitude Rocky Mountain streams to document overwintering assemblages potentially experiencing spring acid pulses. Taxa richness values were comparable to other published lists for alpine and montane stream systems despite the fact that most literature reflected summer collections. Mean benthic density ranged from 1406 to 19,734 organisms/m2, and drift rates ranged from 0 to 1740 organisms/100 m3. Benthic collections showed higher taxa richness than drift collections while the Ephemeroptera and Plecoptera occurred in greater proportions in drift than in benthos. The Nemouridae (Plecoptera), …

Gene Expression In Two Cyanobacteria, Freshwater Synechococcus Sp. Pcc 7942 And Oceanic Synechococcus Sp. Wh 7803, In Response To Ammonium, Nitrate Or Iron, Abbas Sadeghi
Dissertations and Theses
The transcriptional response of freshwater Synechococcus sp. PCC 7942 and oceanic Synechococcus sp. WH 7803 to ammonium, nitrate or iron was studied in single or multiple factor limited cultures. Both strains showed maximum production of NiR mRNA when grown in nitrate-containing media. When grown in ammonium-containing medium, they did not show any signal for NiR mRNA synthesis. The influence on the transcription of NiR mRNA by iron as sole limiting nutrient was also evaluated. Iron increased the NiR mRNA whether or not the positive effect of nitrate was already present. The hybridization signal of mRNA for the large subunit of …
The Reproductive Ecology, Demography, And Population Genetic Structure Of Arctomecon Californica Torrey & Fremont (Papaveraceae) In Fragmented And Unfragmented Habitat, Laura L. Hickerson
The Reproductive Ecology, Demography, And Population Genetic Structure Of Arctomecon Californica Torrey & Fremont (Papaveraceae) In Fragmented And Unfragmented Habitat, Laura L. Hickerson
Biology
Arctomecon californica (the Las Vegas bearpoppy) is endemic to gypsum outcrops of the northern Mojave Desert. Native habitat of this plant in the Las Vegas Valley has been severely fragmented, while relatively undisturbed, unfragmented habitat still exists in the Lake Mead National Recreation Area. I studied the reproductive ecology and population genetic structure of this rare plant. Comparisons were then drawn between fragmented and unfragmented habitat. Arctomecon californica flowers are mostly self-incompatible, and require a pollen vector for successful seed production. Evidence of pollinator limitation was found in both habitat types, but plants in fragmented habitat were much less successful …

Development And Validation Of Forest Habitat Models In The Uinta Mountains, Utah, Tracey S. Frescino
Development And Validation Of Forest Habitat Models In The Uinta Mountains, Utah, Tracey S. Frescino
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A significant question currently facing environmental managers is how to accurately and efficiently quantify forest diversity and resources. Numerous studies have demonstrated the use of modern spatial analytical tools, such as geographical information systems (GIS), remote sensing devices, and statistical models for predicting the distribution of dominant vegetation cover types. This study examines the ability of generalized additive models (GAMs) to delineate structural diversity in forested ecosystems (specifically the Uinta Mountain Range in Utah) using GIS tools and satellite spectral data, and analyzes the effect of including different forms of satellite data in model construction (i.e., Landsat thematic mapper (TM), …

Alaska Research Natural Areas. 4: Big Windy Hot Springs, Glenn Patrick Juday
Miscellaneous Publications
The 65 ha Big Windy Hot Springs Research Natural Area (RNA) in the Steese National Conservation Area of central Alaska is managed by the Bureau of Land Management. It contains a vent that issues hot water at about 61° C flowing at about 8 liters per minute from the largest of a system of small springs and seeps. Geothermal water seeping over the face of a cliff has intensely weathered the local granitic bedrock into gruss. The fracture of massive boulders from the possibly fault-related cliff is one of the most distinctive features of the RNA. Small boulders from the …

Mapping Monthly Precipitation, Temperature, And Solar Radiation For Ireland With Polynomial Regression And A Digital Elevation Model, Christine L. Goodale, John D. Aber, Scott V. Ollinger
Faculty Publications
A 1 km2 resolution digital elevation model (DEM) of Ireland was constructed and used as the basis for generating digital maps of the climate parameters required to run a model of ecosystem carbon and water cycling. The DEM had mean absolute errors of 30 m or less for most of Ireland. The ecosystem model requires inputs of monthly precipitation, monthly averaged maximum and minimum daily temperature, and monthly averaged daily solar radiation. Long-term (1951 to 1980) averaged monthly data were obtained from sites measuring precipitation (618 sites), temperature (62 sites), and the number of hours of bright sunshine per day …
