Abstract
ecological modeling is utilized as a predictor mechanism, to ultimately analyze and observe the various systems and process which govern an ecosystem. With this information available, scientists can attempt to alter an ecosystem based on the interactions of several variables. These models essentially define an ecosystem mathematically; calculating and interpolating the relative rates and probabilities of various natural processes. (Jorgensen, 2008).Some models rely completely on the basis of survivorship; that is, the relative proportions of life and death within a species population. These analyses can be carried out as representations of the survivorship patterns of a species, and can therefore be utilized to determine whether or not a population is in decline or increasing. (Molles & Cahill, 2008) This static method is especially useful when monitoring our rates of harvest towards specific resources. static model are designed as a means to analyze the survivorship of a species based on several discrete variables. (Moles & Cahill, 2008) This method of analysis has been applied to the harvesting of shrimp by commercial fisheries. In order to ensure that a sustainable system is maintained, it is essential to determine a level of harvesting which allows the shrimp populations to remain at a healthy state. Furthermore, as a result of the harvesting, various other species are captured in the process, and must be accounted for. The hawksbill turtle is often a victim of this process, as their populations may be significantly reduced by the relative rates of capture. (Waltho, 2008) This investigation aims to determine whether these species are being harvested in a sustainable manner, or if the rates of harvest require alterations to ensure the survival of the species
