我们讨论了一类空间剥削者-受害者模型，当剥削者平均比受害者分散得更远时，该模型表现出模式的形成。这些模式不是图灵模式：它们类似于神经活动模型中的模式，其中兴奋和抑制的空间差异可以产生空间不均匀的模式。在我们的研究中的模式可能是常见的生态模拟研究中，往往分散内核的选择，似乎是特别容易表现出这样的模式。因为这些模式对分散核的选择非常敏感。我们的研究指出，在基于计算机模拟的生态研究中，从模式中推断过程存在潜在的陷阱。(C)2002 Elsevier Science B. V.保留所有权利。
We discuss a class of spatial exploiter-victim models that exhibit pattern formation when exploiters disperse farther than their victims on average. The patterns are not Turing patterns: they are akin to patterns seen in models for neurological activities where spatial differences in excitation and inhibition can yield spatially inhomogeneous patterns. The patterns in our study may be common in ecological simulation studies where often dispersal kernels are chosen that appear to be particularly prone to exhibiting such patterns. Since these patterns are very sensitive to the choice of dispersal kernels. our study points to a potential pitfall in inferring processes from patterns in ecological studies that are based on computer simulations.
