Dynamics of Satellite Population Related Species with Cyclical Dynamics

Resumo

A theoretical study of population dynamic modes in a biological community including one of the species the abundance of which periodically changes due to causes not related to interspecific interactions in the community was studied. It is shown that these fluctuations may lead to reorganization of the dynamic modes of other community members, which synchronously adapt to the regular change in the abundance of this species. It is noted that asynchronous intrinsic regular and chaotic fluctuations in the abundance of other species may also occur, especially if these species have a high reproductive potential. It is found that the amplitude of fluctuations depends on intrapopulational factors and may significantly exceed the scope of changes in the abundance of the key species.
