Abstract: The behavioral responses of females to male sexual behavior can vary among different sex-ratios. Although reproduction is the key to fitness, it must be weighed against the costs and benefits that accompany it. Operational sex-ratios (OSR) have been used in many studies to measure the variation in male and female interactions. The focus of this study was to measure the effects of OSR on male and female newt behavior and to utilize male chemical cues to assess behavioral responses in females. The aims of this study were to conduct three experiments to determine 1) whether sex-ratio affects male and female newt condition and decisions to become terrestrial versus remaining aquatic 2) to test whether females tend to escape or hide in relation harassment by males and 3) to determine if male chemical cues effect female behavior. Sex-ratio, however, did not have an effect on male and female newt condition and females did tend to orient towards downhill signifying a preference for water. Out of two male biased treatments, females tended to display more escape behaviors with a higher quantity of males versus a lower quantity of males, but no significance was found. Finally, male chemical cues did affect female behavior, but only in the stronger chemical cues. This study took the first step in determining whether the different aspects of sex-ratio influenced various responses from females in different environments.
