Selfministered mail questionnaires were sent to a stratified sample of 1,000 male and 1,000 female Mississippi resident licensed hunters to determine effect of gender on hunting motivations and substitutability of hunting. Exploratory factor analysis and analysis of covariance were used to analyze hunting motivations. Logistic regression was used to determine effects of 14 independent variables on probability of resident hunters reporting a substitute activity. Males and females differed on achievement-oriented “social recognition” and “seeking stimulation” motivations and on affiliative-oriented “family togetherness” motivations. Gender had no significant effect on resident hunter probability of reporting substitute activities. Age and importance of hunting as an outdoor activity had significant effects on probability of reporting substitute activities, with each being related positively to the response variable. Fishing was the most frequently reported substitute activity for males and females. However, females reported more substitute activities than males.

Cotton is a valuable fiber crop around the world used to create fabrics, oils, and currency. The threat of herbicide resistant (HR) weed populations is precarious for cotton production. The overreaching objective of this study was to phenotype potentially allelopathic chromosome substitution (CS) lines to determine competitive accessions. The identification of competitive cotton lines would be useful in the development of alternative weed control tools. Twelve CS lines (CS-49, CS-38, CS-34, CS-39, CS-27, CS-13, CS-50, CS-26, CS-25, CS-43, CS-46, and CS-23) along with the parent line (TM1) and two conventional varieties (UA48 and Enlist) were screened in a greenhouse using the stairstep structure. Eight CS lines were then selected to test in the field and analyzed in the lab to identify allelochemical exudates using HPLC. Results of this study provide a greater insight into the nature of allelopathy and its potential usefulness in cotton crops.
