Spatial patterns and biodiversity in rock-paper-scissors models with regional unevenness

Climate changes may affect ecosystems destabilising relationships among species. We investigate the spatial rock-paper-scissors models with a regional unevenness that reduces selection capacity of organisms one Our results show regionally weak species predominates in local ecosystem, while spiral patterns appear far from region, where individuals every play game same strength. Because controls all territory, it is attractive for other to enter ecosystem conquer territory. However, our stochastic simulations transitory waves formed when strong reach region are quickly destroyed because strength unbalance rules. Computing effect topology on population dynamics, we find prevalence becomes more significant if transition area uneven rules smooth. Finally, findings biodiversity loss due arising minimised cyclic unbalanced abrupt. be helpful biologists comprehending consequences environmental conditions coexistence and complex systems.
