This data has determined the lower end of the comfort zone for black rhinoceros and has implications in the husbandry and care of these animals. Robert James Martin Jr. The purpose of this study was to determine the radiative heat exchange between two black rhinoceros and their enclosures at Zoo Atlanta during exposure to heat. Data collected at Zoo Atlanta over four years was used to determine the biophysical heat exchange between the rhinoceros and their captive environment. Graduate Oral Presentations 1.
Soil salinity is a significant problem in crop production worldwide.
The goal of this research effort is to produce transgenic plant lines that express the product of the yeast casein kinase II gene. This gene, when overexpressed in the yeast S. cervisae, has been shown to convey salt tolerance. My hypothesis is that expression of this gene in plant tissues will result in salt tolerance to the transgenic plant. Abscisic acid was extracted from both the control and salt tolerant callus tissues and subjected to HPLC analysis. The increase in ABA concentration precedes the observed increases in antioxidant enzyme activities, providing additional evidence that ABA is involved in the signal transduction pathway responsible for the NaCl-induced upregulation of antioxidant enzyme activity.
