The Influence of Temporal Migration in the Synchronization of Populations

Abstract: ABSTRACT.A discrete metapopulation model with temporal dependent migration is proposed in order to study the stability of synchronized dynamics. During each time step, we assume that there are two processes involved in the population dynamics: local patch dynamics and migration process between the patches that compose the metapopulation. We obtain an analytical criterion that depends on the local patch dynamics (Lyapunov number) and on the whole migration process. The stability of synchronized dynamics depends… Show more

“…For example, Figure 6a shows the pattern with concentric circles and only oscillations with a period equal to 3 for ρ = 0.5. However, with the same parameters but a considerably large range of random initial conditions, we observe several types of dynamics of the local population in the models (4) and (5). Figure 6b shows that the solitary states and the small clusters have the chaotic synchronization close to the 3-cycle and by strong bursts (C 3 ), whereas the surrounding subpopulations with weak fluctuations show irregular dynamics in time and space (C 1 ).…”

“…Under these random initial conditions, the spatial structures and dynamics of individual elements are still determined by the shape of the subpopulation neighborhoods in models ( 2) or ( 4) and (5). Such initial conditions rarely lead to highly symmetrical patterns, as shown in previous examples.…”

“…Число локальных популяций может быть постоянным или переменным, когда субпопуляции разного размера в ходе развития метапопуляции сменяют друг друга. Традиционно моделирование динамики метапопуляций в современной популяционной биологии идет с привлечением камерного подхода на основе как непрерывных, так и дискретных моделей [Allen, 1975;Legendre, Fortin, 1989;Opdam, 1991;Gyllenberg, Hanski, 1992;Gyllenberg et al, 1993;Hanski, Gyllenberg, 1993;Udwadia, Raju, 1997;Wysham, Hastings, 2008;Gyllenberg et al, 2009;Manica, Silva, 2014, 2015.…”

“…Для этих систем наибольший интерес вызывают такие аспекты динамического поведения, как синхронизация и когерентность динамики популяций и сообществ на удаленных территориях, а также механизмы формирования пространственно неоднородного распределения особей по территориям. Традиционным модельным объектом теоретических исследований динамики метапопуляций выступают связанные популяции с непересекающимися поколениями [1,2,3,4], динамика которых описывается, как правило, системами связанных одномерных отображений. Исследование систем связанных популяций, дополнительно обладающих половозрастной структурой встречаются не так часто [5].…”
