A simple model is suggested to describe dynamics of spatially dispersed community consisting of two species, a prey and a predator. These species occupy two biotopes, shifts between them being considered as migrations (a box migration model). Migrations are not random but lead to maximization of an average (in respect to the range) reproduction coefficient for the entire species. The basic model of community dynamics with purposeful migration is explored together with its three modifications. The modified models consider reflexive nature of spatial behavior of prey (1st modification), predator (2d modification), and the both (3d modification). Evolutionary advantages of reflexive behavior relative to non-reflexive one are studied.
提出了一个简单模型来描述由两个物种（一个猎物物种和一个捕食者物种）组成的空间分散群落的动态。这些物种占据两个生物群落，它们之间的转换被视为迁移（一种箱式迁移模型）。迁移并非随机进行，而是会使整个物种的平均（在范围方面）繁殖系数最大化。探讨了具有定向迁移的群落动态基本模型及其三种修正模型。修正模型考虑了猎物（第一种修正）、捕食者（第二种修正）以及两者（第三种修正）空间行为的自反性质。研究了自反行为相对于非自反行为的进化优势。
