Abstract: Warming is the biggest and most serious of the environmental problems of the day, and it's a matter of survival for living things. Warming is causing metabolic disorders, oxidative stress, immunosuppression and even death in animals. In order to survive, animals have to learn to adapt to climate change, which can be reflected in behavioural and physiological changes, such as early migration of birds, changes in habitat location in response to temperature changes in metazoans, and even modulation …

Abstract: Adaptive sex ratio variation is a remarkable phenomenon in the biological world. Lampreys are one of the examples. Some researches have shown that the sex ratio of sea lampreys can vary based on external circumstances, and some scholars believe that. the Great Lakes can improve the eco-environment of fish stocks by changing the sex of lampreys. This paper studied the ability for a species to alter its sex ratio depending on resource availability, and provided the resulting interactions in an …

Abstract: An interaction model between lampreys and ecosystem based on logistic equation is established. By solving the differential equations, the sex ratio of lampreys varies with the number of other populations, the number of its own population and the growth rate. The results suggest that changes in the sex ratio will give lampreys an advantage in population competition and inhibit the development of other populations.Logistics equations to study the performance of lampreys in population competition, …
