Abstract：
Life history (LH) strategies are results of trade-offs that species must make due to inhabiting certain ecological niches. Although it is assumed that, through the process of developmental plasticity, similar trade-offs are made by individuals in response to a certain level of harshness and unpredictability of their local environments, the study results on this matter are not consistent. In LH-oriented psychological research, such inconsistencies are often explained as a consequence of significant individual differences in phenotypical quality and owned resources, which make studying trade-offs difficult due to different costs and benefits of the same behaviors taken by different individuals. To verify if traditional LH patterns can be found among individuals with more comparable qualities, than in the general population, the current study was conducted on a group of male criminal offenders, who are typically associated with a fast LH strategy. Our results did not show any support for either LH trade-offs or unidimensional character of LH strategies in the criminal group studied. The traditional biodemographic LH traits, that we used to assess a LH strategy, merged into three well-known LH dimensions (mating, parenting, and somatic effort) that yet turned out to be entirely independent from each other. Moreover, each LH dimension turned out to be uniquely related to a different aspect of the developmental environment. The implications of the obtained results are discussed.
摘要：
生活史（LH）策略是物种由于居住在某些生态位而必须进行权衡的结果。虽然假定,通过发育可塑性的过程，类似的权衡是由个人做出的，以应对他们当地环境的一定程度的严酷和不可预测性，关于这个问题的研究结果并不一致。在以LH为导向的心理学研究中，这种不一致通常被解释为表型质量和自有资源的显著个体差异的结果，由于不同个体采取的相同行为的不同成本和收益，这使得研究取舍变得困难。为了验证传统的LH模式是否可以在具有更多可比质量的个体中找到，比一般人口，目前的研究是针对一群男性罪犯进行的，通常与快速LH策略相关。我们的结果没有显示出对所研究犯罪集团中LH权衡或LH策略的一维特征的任何支持。传统的生物人口学LH特征，我们用来评估LH策略的，合并成三个众所周知的LH维度(交配，育儿,和躯体努力)，但事实证明它们是完全独立的。此外，每个LH维度都与发育环境的不同方面唯一相关。讨论了所得结果的含义。
