Effect of periodic environmental fluctuations on the Pearl-Verhulst model. (English) Zbl 1197.34062

Chaos Solitons Fractals 39, No. 3, 1169-1181 (2009).
Summary: We address the effect of periodic environmental fluctuations on the Pearl-Verhulst model in population dynamics and clarify several important issues very actively discussed in recent papers of B. S. Lakshmi [ibid. 16, 183–186 (2003); ibid. 26, 719–721 (2005; Zbl 1032.92028)], P. G. L. Leach and K. Andriopoulos [ ibid. 22, 1183–1188 (2004; Zbl 1081.92033)], J. H. Swart and H. C. Murrell [ibid. 32, 1325–1327 (2007; Zbl 1195.92054)]. Firstly, we review general results regarding existence and properties of periodic solutions and examine existence of a unique positive asymptotically stable periodic solution of a non-autonomous logistic differential equation when \(r(t)>0\). Proceeding to the case where \(r(t)\) is allowed to take on negative values, we consider a modified Pearl-Verhulst equation because, as emphasized by T. G. Hallam and C. E. Clark [J. Theor. Biol. 93, 303–311 (1981)], use of the classic one leads to paradoxical biological conclusions. For a modified logistic equation with \(\omega \)-periodic coefficients, we establish existence of a unique asymptotically stable positive periodic solution with the same period. Special attention is paid to important cases where time average of the intrinsic growth rate is non-positive. Results of computer simulation demonstrating advantages of a modified equation for modeling periodic environmental fluctuations are presented.
Editorial remark: There are doubts about a proper peer-reviewing procedure of this journal. The editor-in-chief has retired, but, according to a statement of the publisher, articles accepted under his guidance are published without additional control.
