文化生态位构建是指某些进化中的文化特征形成一个影响其他遗传和文化特征进化的文化生态位的过程[Laland，K.，例如，2001.文化生态位建构与人类进化。J. Evol. 14，22-33; Ihara，Y.，费尔德曼，M.，2004.文化生态位建构与小家庭规模的演化。Theor.波普尔65，105-111]。在这项研究中，我们专注于文化生态位的建设在一个集合种群（人口的人口），其中一个文化特征的频率（例如教育水平）决定了第二个特征的传播率（例如通过生育率降低偏好）内和人口之间。我们通过将第一个特征诱导的文化生态位定义为第二个特征可能渗透的社会互动网络的构建，建立了元人口文化生态位构建（MPCNC）模型。对模型的分析揭示了与在单个种群中观察到的动态明显不同的动态，例如，允许每个种群中存在不同（甚至相反）的动态。特别地，该模型可以解释先前研究中报道的令人困惑的现象[Bongaarts，J.，Watkins，S.，1996.社会互动与当代生育率转变。波普尔Dev. Rev. 22（4），639-682]指出，不同国家的人口结构转变发生在发展水平越来越低的时候。(c)2005年爱思唯尔公司All rights reserved.
Cultural niche construction is the process by which certain evolving cultural traits form a cultural niche that affects the evolution of other genetic and cultural traits [Laland, K., et al., 2001. Cultural niche construction and human evolution. J. Evol. Biol. 14, 22-33; Ihara, Y., Feldman, M., 2004. Cultural niche construction and the evolution of small family size. Theor. Popul. Biol. 65, 105-111]. In this study we focus on cultural niche construction in a metapopulation (a population of populations), where the frequency of one cultural trait (e.g. the level of education) determines the transmission rate of a second trait (e.g. the adoption of fertility reduction preferences) within and between populations. We formulate the Metapopulation Cultural Niche Construction (MPCNC) model by defining the cultural niche induced by the first trait as the construction of a social interaction network on which the second trait may percolate. Analysis of the model reveals dynamics that are markedly different from those observed in a single population, allowing, for example, different (or even opposing) dynamics in each population. In particular, this model can account for the puzzling phenomenon reported in previous studies [Bongaarts, J., Watkins, S., 1996. Social interactions and contemporary fertility transitions. Popul. Dev. Rev. 22 (4), 639-682] that the onset of the demographic transition in different countries occurred at ever lower levels of development. (c) 2005 Elsevier Inc. All rights reserved.
