Abstract

This study explores the impact of variations in the sex ratio of lampreys on ecosystem dynamics within a food web context. Using the Volterra predation and prey model, the research analyzes the natural growth and decline rates of populations, predator-prey relationships, and competition. The paper examines how changes in the sex ratio of lampreys affect the populations of herbivores, omnivores, and carnivores, as well as the survival of indigenous people. The analysis utilizes biological data from juvenile sea lampreys and employs Matlab for data fitting, establishing a relationship between the sex ratio of lampreys and the availability of food in the ecosystem. The findings highlight the interconnectedness of species within the food web and the significant role of sex ratio variations in lampreys on the larger ecosystem.
