North American bighorn sheep (Ovis canadensis) have experienced significant declines and population extirpations due to novel pathogens such as Mycoplasma ovipneumoniae. This disease continues to limit the population restoration of bighorn sheep. Therefore, understanding the demographic consequences of pathogen presence and the risk of contact between bighorn populations and potential...
This study investigated the private costs to individual households
of large-lot zoning policies. The study asked whether typical
zoning ordinances create shortages of small lots or small structures
and, if so, what the magnitude of the resultant welfare loss is.
The hypotheses were suggested by a theoretical model developed
to...
The ingestion, uptake, and metabolism of liposomes by juvenile
Pacific oysters (Crassostrea gigas) were studied by several methods in
an effort to assess their potential as encapsulating agents. Liposomes
composed of egg phosphatidylcholine-cholesterol-stearylamine (7:1:2)
formed readily and appeared stable in 20°/oo seawater. Radiotracer
studies with liposomes made with ¹⁴C-labeled cholesterol...
