Abstract:The Allee-like effect in metapopulation is similar to local population subject to the Allee effect. It is introduced into the two-competitive metaspecies system to establish a two-metaspecies dynamic model subject to the Allee-like effect. Numerical simulation results show that: (1) The Allee-like effect could lead to multiple stable states in the two-metaspecies competitive system. (2) It causes the coexistence impossible and even extinction of both species. Ultimate equilibrium will be changed with initial patch occupancies. (3) With competitive exclusion, the Allee-like effect could cause all species to go extinction. The stronger the Allee-like effect is, the shorter the species′ survival period will be. It degrades the superior species to be inferior and upgrades the inferior superior, similar in habitat destruction affecting the species ecological order. (4) As a destabilizing factor in stability and in metaspecies persistence in the evolvement, it will significantly affect the equilibrium even if it is slightly changed. As to a stable system, the Allee-like effect regulates the abundance of both metaspecies instead of reducing their equilibrium values, which reveals its influence on competitive metaspecies′ dynamics varies in different periods. The above conclusions mean a great deal to species conservation and metacommunity management.
