大多数以前的混合繁殖模式的种群模型都忽略了有性个体和无性个体之间重要的局部相互作用。我们提出了一个元胞自动机模型，其中局部规则集中在受精和定居上。该模型产生了丰富的数据集，然后通过空间统计对其进行研究。结果表明，这两种繁殖模式中的一种是固定在景观中的。然而，也发现了一些在很长一段时间内有性和无性共存的例子。这个模型是CA偏离其平均场近似的一个例子。有性群和无性群的形成降低了在CA的有效定殖率，这可能是这种行为的原因。(C)2002爱思唯尔科学有限公司。保留所有权利。
Most previous models of populations mixed for reproductive mode have omitted important local interactions between sexual and asexual individuals. We propose a cellular automaton model where local rules focus on fertilization and colonization. This model produces rich sets of data which are then studied by means of spatial statistics. Results point to the fixation of one of the two reproductive modes in the landscape. However, some examples of coexistence of sexual and asexual conspecifics over long periods of time are also found. This model is an example of a CA that diverges from its mean field approximation. The formation of sexual and asexual clusters reduces effective colonization rate in the CA and may account for this behaviour. (C) 2002 Elsevier Science Ltd. All rights reserved.
