Furthermore, the effects of intraspecies density dependence (IDD) on the dynamics of the model are investigated. It has been found that the addition of IDD to a three-species ecological model stabilizes the system, changing the dynamics from chaotic to periodic. Finally, the effects of external stochastic disturbances (ESD) on chaotic population dynamics are investigated using bifurcation diagrams and chaotic attractors. The results show that the system exhibits rich and complex features, including stable, periodic, and chaotic dynamics.","PeriodicalId":279256,"journal":{"name":"2009 International Workshop on Chaos-Fractals Theories and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129863855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the process of long-term population dynamics study of the dominant rodent species in North China Plain, we found the density change is very complicated and often influenced by a series of ecological factors both intrinsic and extrinsic. In many cases the population dynamics is nonlinear. Therefore, in this paper we attempt to analyze the Cricetulus Barabensis population of Wendeng City (37°12′N, 122°03′E) in North China Plain during 1982-2003 from two aspects (non-linearity and chaos). The computing methods include Hurst Exponent and chaos verifying ways such as Lyapunov exponents. The results show that the dynamics of Cricetulus Barabensis population is nonperiodic, nonlinear, and chaotic.","PeriodicalId":279256,"journal":{"name":"2009 International Workshop on Chaos-Fractals Theories and Applications","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116976030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the existence and local stability of the fixed points in the closed first quadrant are discussed in detail. Then, by using center manifold theorem and bifurcation theory, it is proved rigorously that when the bifurcation parameters vary in the small neighborhood of the corresponding bifurcation set, flip bifurcation and Hopf bifurcation can emerge near the unique positive fixed point of the system. To suppress the undesirable chaos induced by the period-doubling bifurcation and stabilize the unstable period-1 point embedded in the chaotic attractor, periodic feedback control scheme is proposed. For this system, it is easy to verify that 1 is not the eigenvalue of the Jacobian matrix near the period-1 point, hence, the gain matrix can be obtained analytically. Numerical simulations are presented to illustrate our results with the theoretical analysis and show the effect of the control method.","PeriodicalId":279256,"journal":{"name":"2009 International Workshop on Chaos-Fractals Theories and Applications","volume":"354 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122799210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
