Competition is the main theme of the biological world.A large number of species coexist and interact with each other in the natural world,forming complex ecological communities.It is not the strongest of the species that survive,but the one most responsive to change.The behavioral strategies of species always revolve around the eternal theme of "survival".Their strange behaviors in the process of survival are full of fun and anthropomorphic,and have a deep sense of exploration.The world is currently facing a biodiversity crisis,with a large number of species on the verge of extinction,and if the crisis persists,human survival will eventually be threatened.Therefore,it is essential to study the complex behavior of these ecosystems in order to understand nature and protect biodiversity.In evolutionary biology,studying the behavior of organisms is central to understanding how to manage ecosystem conservation.Scholars studying ecology have been working to understand the diverse species and complex dynamics of behavior in natural ecosystems.Among the many approaches to studying complex systems,stochastic simulation is an important tool that has been widely used to study the collective behavior of organisms in nature,and in particular has been used to model and understand biodiversity in nature.Based on the rock-paper-scissors game on complex networks,the use of stochastic simulation methods is key to understanding not only biodiversity,but also various properties in the cyclic systems of nature.In this paper,we investigate the impact of species behavior on biodiversity based on the RPS game,which is based on the presence of consciousness and adaptive behavior of species,and the presence of disease,which leads to the phenomenon of "predation of the weak".The study is divided into two parts,the first part is based on a rock-paper-scissors game to study the effect of species awareness on biodiversity.Species recognize their surroundings and then perform adaptive behaviors,such as avoiding enemy attacks or capturing prey,based on the predator-prey relationship,which is one of the common behaviors of populations in ecosystems.Using the ecological concept of "species consciousness",the relationship between the behavior of these species and biodiversity in a spatial rock-paper-scissors game is discussed.A two-layer network structure is adopted to describe species consciousness,where two different layers describe virtual and physical interactions,respectively.By studying the evolutionary process of species,the results show that species with different species consciousness co-exist.Species with high consciousness can coexist in the vast majority of migration rate situations,but too high consciousness can disrupt coexistence.In addition,using a dynamic time-warping approach,the results demonstrate that species with the same species consciousness have consistent behaviors and species with different species consciousness have different behaviors.The existence of species consciousness facilitates the stability of ecosystems and the coexistence of organisms.This finding suggests a broader explanation for the mechanisms that promote biodiversity through species consciousness in species ecosystems.The second part investigates the impact of disease transmission on biodiversity based on a rock-paper-scissors game.A three-species cyclic game system is investigated in which some individuals of one species are initially exposed to an infectious disease and the diseased individuals act as virus carriers,transmitting it to other healthy individuals through interactions or the environment.Based on the natural law of "survival of the fittest" and the ecologically proven mobility constraints,we explored the effects of differences in competitive ability due to disease transmission on the ecosystem from the perspective of high mobility rates.The results show that at high mobility levels,competitive ability differences have a significant impact on biodiversity,and that appropriate competitive ability differences can offset biodiversity extinction at high mobility levels.Differences in competitive ability and disease recovery rates together affect species extinction.The intensity of competitive ability differences that can ensure stable coexistence of the system varies under different recovery rate scenarios.By further observing species evolution,we found that a greater proportion of "weak" species interactions and disease transmission occurred at competitive boundaries.The study of complex ecosystems and species behavior from the perspective of species consciousness and disease transmission further deepens the study of ecosystems based on rock-paper-scissors games,which enriches the existing research results.The main innovation is that this paper introduces the natural phenomenon that the existence of species consciousness affects the behavior of organisms into the RPS game.We also use time dynamic distortion to explore the influence of species categories and consciousness categories on the behavior of individual movements.In terms of disease transmission,this paper investigates the effect of disease on population dynamics in the RPS game from the different perspective of the effect on the difference in competitive ability following the infection of individuals with the disease.These research ideas and results help us to enhance our understanding of the complex natural world and serve as a reference for ecologists to take relevant measures to develop ecosystem conservation strategies.
