The aim of this study was to investigate the effects of external environmental factors on the sex ratio of lampreys and the possible changes in population size and structure as a result of such effects. We simulated the population dynamics of male and female lampreys separately by modeling the population dynamics of lampreys based on the Lotka-Volterra model, and considered the effects of human predation on the lamprey population. By adjusting model parameters, such as predation intensity, initial sex ratio and rate of change in sex ratio dynamics, we simulated changes in the sex ratio of lampreys under different conditions and observed the effects of such changes on the ecosystem. The results suggest that changes in the sex ratio of lampreys may lead to changes in the abundance and distribution of other species, which in turn may affect the stability of the ecosystem. In addition, we analyzed the model results and presented graphs showing changes in predator and prey population dynamics and changes in lamprey sex ratios, further illustrating the effects of changes in sex ratios on ecosystem dynamics, population size and stability.
