20.500.12556/DKUM-66542 Emergence of target waves in paced populations of cyclically competing species We investigate the emergence of target waves in a cyclic predator-prey model incorporating a periodic current of the three competing species in a small area situated at the center of a square lattice. The periodic current acts as a pacemaker, trying to impose its rhythm on the overall spatiotemporal evolution of the three species. We show that the pacemaker is able to nucleate target waves that eventually spread across the whole population, whereby three routes leading to this phenomenon can be distinguished depending on the mobility of the three species and the oscillation period of the localized current. First, target waves can emerge due to the synchronization between the periodic current and oscillations of the density of the three species on the spatial grid. The second route is similar to the first, the difference being that the synchronization sets in only intermittently. Finally, the third route toward target waves is realized when the frequency of the pacemaker is much higher than that characterizing the oscillations of the overall density of the three species. By considering the mobility and frequency of the current as variable parameters, we thus provide insights into the mechanisms of pattern formation resulting from the interplay between local and global dynamics in systems governed by cyclically competing species. cyclical interactions target waves spatial games diversity ciklične interakcije tračni vali prostorske igre diverziteta true true true Angleški jezik Slovenski jezik Članek v reviji 2017-06-30 12:34:13 2017-06-30 12:35:47 2024-05-28 09:57:58 2019-07-11 15:50:56 2009 0 0 str. 1-14 Letn. 11 2009 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1367-2630 519.83:536.94 21135621 13684758 10.1088/1367-2630/11/10/103001 1367-2630 URN:SI:UM:DK:YATXLWFK New_Journal_of_Physics_2009_Jiang_et_al._Emergence_of_target_waves_in_paced_populations_of_cyclically_competing_species.pdf New_Journal_of_Physics_2009_Jiang_et_al._Emergence_of_target_waves_in_paced_populations_of_cyclically_competing_species.pdf 1 225E3F071E01843DA90BE8930C540835 52b1ac102a8ca344c52b0f2c21cd16fafc1e72901910f7f8c20140dfcee53f58 54236aab-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113400 http://stacks.iop.org/1367-2630/11/i=10/a=103001?key=crossref.8dc2959358a7724d2a1bfe054397df15 1 https://dk.um.si/Dokument.php?lang=slv&id=113399 Fakulteta za naravoslovje in matematiko 0 0 0
