Lamprey, sex ratio, Ecology, Food availability.Abstract
This study examined the effects of sex ratio on ecology, using Lamprey as the study population. It was found that there was a close relationship between sex ratio and food availability, with a higher proportion of female Lamprey when food availability was adequate and an increase in the proportion of males when food was scarce.The relationship between sex ratio and population dynamics of Lamprey was established by logistic growth model and Lotka-Volterra predator-prey model, and it was found that the change of sex ratio had a significant effect on the population size of Lamprey, which will affect the number of prey as well as the ecological factors such as water temperature and pH value.These discoveries reveal the important role of gender ratio in the ecosystem, and provide new perspectives and methods to solve the dynamics and resource utilization in the ecosystem.
