A five-year clipping experiment was conducted to determine maximum sustained utilization levels for three big game browse plant species in
central Arizona. The three species were mountain-mahogany (Cercocarpus
breviflorus) and desert ceanothus (Ceanothus Greggii) in the chaparral
type, and cliff-rose (Cowania mexicana var. Stensburiana) in the pinyon-juniper type. Experimental treatments...
Low levels of copper have been shown to impair the olfactory system of threatened and
endangered (T&E) salmon, decreasing their predator avoidance behavior and likely
increasing mortality. However, only dissolved copper (dissCu) present as the cupric ion
(Cu2+) and weakly complexed species are truly bioavailable. Previous studies indicate the
vast...
Since Ranked Set Sampling (RSS) was proposed in 1952 by G.A. McIntyre, it has been the subject of many statistical investigations and a large number of field studies. Throughout these studies RSS has been proven to provide a better estimate of population the mean and variance than Simple Random Sampling...
The first part of this thesis describes a study of the
characteristics of oxidation of a 1:2 iron(III):thiolate system in
methanolic solution and in water. This system was investigated as a
potential analog for the cysteine- and cysteamine-dioxygenase catalyzed
0₂-oxidation of cysteine and cysteamine, respectively, to the
corresponding sulfinic acids....
