To date, there is a scant amount of research on the long-term benefits of exercise training for individuals with moderate to severe chronic obstructive pulmonary disease. The purpose of this study was to evaluate standardized outcomes of a six-month maintenance pulmonary rehabilitation program to determine maintenance of functional capacity. Twenty-three subjects (sixteen men, seven women) diagnosed with clinical COPD ages 30-82 (65 + 12 years) participated in the retrospective study. The subjects were referred to an eight-week comprehensive pulmonary rehabilitation program after which upon twelve subjects continued onto a maintenance program. Eleven subjects chose not to participate in the maintenance program and were given a home exercise program and were encouraged to remain active. Hemodynamic, functional, and educational measures were taken prior to entry, upon completion of the hospital program, and again six-months post-program. Outcome tests were standardized using the Indiana Society of Cardiovascular and Pulmonary Rehabilitation Outcomes Manual. Significantdifferences were found between the maintenance and non-maintenance groups for systolic blood pressure in resting, exercise, and recovery measures at six months reevaluation. Differences in oxygen saturation were also found to reach significance between the two groups during recovery from the six-minute walk test. Interestingly, duration of exercise was found to be statistically significant between the two groups as well as emergency room visits and physician visits within the last six months. The maintenance group tended to have fewer emergency room and physician visits in addition to having self-reported higher durations of exercise. In conclusion, maintenance pulmonary rehabilitation programs have been shown to maintain physical activity levels for COPD patients and as a result, fewer quality of life consequences specifically the number of hospital admissions and emergency room visits. / Department of Biology

Female Misumenoides formosipes crab spiders, unlike their highly mobile, short-lived male counterparts, are relatively sedentary predators that forage long after the males have died off. Associated with their foraging ability is a phenomenon rare amongst animals: the capacity for a reversible change in body color. This color change ability, exhibited by several species of crab spiders, has historically been interpreted as an adaptation providing enhanced crypsis during movement between hunting substrates (inflorescences). Misumenoides formosipes females were relocated onto matched and mismatched substrates in the field to assess their propensity for color change, the rate at which it occurs, and any impact on foraging success. Yellow females transferred to white inflorescences were the only category that did not remain in their new location. White females changed to yellow over a 9 day period. We found conflicting evidence as to whether or not foraging success was enhanced for females on matched backgrounds. / Department of Biology
