ts A statistical test was ran for each respective life history aspect of R0, r, and G to test for statistical significance between the two temperatures. The net reproductive rate statistical test between the two temperatures gave a p value of much less than 0.05 (p-value = 1.97e-06). This signifies that the null hypothesis can be rejected. Concluding that net reproductive rate does have a significant difference between the two temperatures. For intrinsic growth rate the p value was also less than 0.05(1.778e-06) rejecting the null hypothesis. Intrinsic growth rate does exhibit a significant difference between the two temperatures. Mean generation time’s statistical test between the two seasons also resulted in a p-value of less than 0.05 (p-value < 2.2e-16). Concluding that mean generation time does exhibit a significant difference between the two temperatures. Intrinsic growth rate (r) and Net reproductive rate were found to have a strong POSITIVE linear correlation. Figures: Unit for each R0, r and G is Avg. number of offspring. Figure 1.

Discussion The Gambusia Holbrooki population sampled and tested in our study supported a rejecting of our null hypothesis. It can be concluded that in our sampled population of G. Holbrooki temperature does have a significant effect on aspects of life history that were tested in our study i.e. Intrinsic growth rate (r), net reproductive rate (R0), and Mean Generation time(G). Net reproductive rate is the avg. number of offspring born to a female in her lifetime. In our study the net reproductive rate was found to exhibit a significant difference between the two temperatures of Summer and Winter. Some supporting evidence for this finding is reflected in a 28-year study where Gambusia Holbrooki were exposed to the abnormally high temperature of 32 degrees Celsius rather than normal conditions of 25 degrees Celsius. The mosquitofish in the higher temperatures were found to mature at younger ages than the fish in normal conditions.(Meffe,1992). It could be deduced that if fish were maturing earlier, they would in turn have an earlier sexual maturation age. Intrinsic growth rate is defined as the rate that a population grows over a successive period of time. Our results showed that intrinsic growth rate did exhibit a significant difference between the two temperatures. A possible ecological explanation to support this could lie in the finding that food availability increases as temperatures rise. (Vondracek, Bruce, et. Al.,1988). One behavioral study observed that Eastern mosquitofish mating became very restricted in higher than normal temperatures (30-35 degrees Celsius). ((Wilson,2004)). These findings help provide possible explanations for our result of intrinsic growth rate exhibiting a significant difference between two different temperatures. Mean generation time is average amount of time it takes for a female to give birth to her first offspring. In our results the mean generation time exhibited a significant difference between the two temperatures. A possible ecological explanation for this is displayed in a study taking place in Lake Herviz where the highest number of pregnant females were found to be from August to July when temperatures were warmer (Specziar,2004).
