How does Deborah Stone’s metaphor of dividing a chocolate cake eight different ways explain equality?
ductive 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). There seems to be a consistent trend in the research provided in which, warmer temperatures lead to quicker developmental maturation. It’s also important to note that intrinsic growth rate (r) and net reproductive rate (R0) have a positive linear relationship. Meaning that as one increases so does the other and vice-versa. Each one of our findings have a great degree of ecological importance. The finding that net reproductive rate, mean generation time, and intrinsic growth rate each held a significant difference in between the two differing temperatures may provide support by providing insight on obdurate ecological issues being faced today in relation to G.Holbrooki, such as, the introduction of mosquitofish decimating amphibian species (Hamer, et. Al,2002) or how introduction of the G.Holbrooki has also been found to cause algal blooms that are harmful to the environment, caused by their feeding on zooplankton ((Hurlbert et al. 1972) and how they’ve displaced certain topmin>
