物种进入群落的顺序和环境条件，如温度，都已知会影响群落结构。然而，鲜为人知的是，关于潜在的，发生的，组装历史和环境之间的相互作用。特别感兴趣的可能是温度和社区组装动态之间的相互作用，特别是根据预测的全球气候变化和基本过程，通过代谢率，由个人的环境温度。我们目前，据我们所知，第一次实验探索如何组装的历史，温度，以及两者之间的相互作用的影响改变了竞争对手的社区的结构，使用小规模的原生生物微观世界的社区，温度和组装顺序被操纵factorally。在我们的实验中，长期丰度的最重要驱动因素是温度，但长期的组装顺序影响温度和丰度之间的关系。早期殖民的任何优势都被证明是短暂的，在其他物种之前殖民栖息地很少有任何长期优势。这里提出的结果表明，环境条件的形状社区组成，但偶尔温度可以与随机性质的社区组装显着改变未来的社区组成，特别是在温度变化很大。这可能对稀有物种和入侵物种的动态产生重要影响。
Both the order in which species arrive in a community, and environmental conditions, such as temperature, are known to affect community structure. Little is known, however, about the potential for, and occurrence of, interactions between assembly history and the environment. Of particular, interest may be the interaction between temperature and community assembly dynamics, especially in the light of predicted global climatic change and the fundamental processes that are governed, through metabolic rate, by an individual's environmental temperature. We present, to our knowledge, the first experimental exploration of how the influence of assembly history, temperature, and the interaction between the two alters the structure of communities of competitors, using small-scale protist microcosm communities where temperature and assembly order were manipulated factorially. In our experiment, the most important driver of long-term abundance was temperature but long-lasting assembly order effects influenced the relationship between temperature and abundance. Any advantage of early colonization proved to be short-lived, and there was rarely any long-term advantage to colonizing a habitat before other species. The results presented here suggest that environmental conditions shape community composition, but that occasionally temperature could interact with the stochastic nature of community assembly to significantly alter future community composition, especially where temperature change has been large. This could have important implications for the dynamics of both rare and invasive species.
