Road Zone Effects in Small-Mammal Communities Ecology and Society
Bissonette, John A.; USGS Utah Cooperative Fish and Wildlife Research Unit, Department of Wildlands Resources, College of Natural Resources, Utah State University; john.bissonette@usu.edu; Rosa, Silvia A.; USGS-Utah Cooperative Fish and Wildlife Research Unit, Department of Wildlands Resources, College of Natural Resources, Utah State University; silviarosa2007@gmail.com.
Our study focused on the putative effects of roads on small-mammal communities in a high desert region of southern Utah. Specifically, we tested whether or not roads create adjacent zones characterized by lower small- mammal densities, abundance, and diversity. We sampled abundance of small mammals at increasing distances from Interstate 15 during two summers. We recorded 11 genera and 13 species. We detected no clear abundance, density, or diversity effects relative to distance from the road. Only two of 13 species were never captured near roads. The abundance of the remaining 11 small mammal species was either similar at different distances from the road or higher closer to the road. We conclude that although roads may act as barriers and possible...

Effect of hydrogen ions and inorganic complexing on the uptake of copper by the brine shrimp <i>Artemia franciscana</i> OMA
Blust, R.; Fontaine, A.; Decleir, W..
The effect of hydrogen ions and inorganic complexing on copper uptake in the brine shrimp <i>Artemia franciscana</i> has been studied in chemically defined saltwater solutions. Uptake increases with decreasing hydrogen ion concentration and decreases with increasing carbonate complexation. A simple non-linear model that combines the effect of hydrogen ions on the transport of the metal across the solution-body interface and the effect of hydrogen ions and complexation on the speciation of the metal provided a close functional description of the observed variation in copper uptake by brine shrimp.

The history, present status and prospects of the availability of <i>Artemia</i> cysts for aquaculture OMA
Lavens, P.; Sorgeloos, P..
This paper provides an overview of the history of <i>Artemia</i> cyst provision worldwide since the 1950s. It allows a better assessment of the current situation, characterized by poor yields from the main harvest site, the Great Salt Lake in Utah, USA, and to make prognoses about future supplies and demands.

Organizing Meatpacking Cooperatives: Recent Producer Attempts AgEcon
Hogeland, Julie A..
Montana Livestock Cooperative and the Utah-based Intermountain Livestock Packing Association are meatpacking cooperatives established through equity and livestock commitments by producers. Their goals are to obtain sufficient capital to construct and operate a slaughter/processing plant. Member involvement requires a comprehensive feasibility study to show need for the plant and an understanding of cooperative organization.
