慢-快行为和生活史差异与认知的慢-快变化有关，这是一般速度-准确性权衡的一部分。虽然有越来越多的证据表明这种认知变异及其与种内水平的行为和生活史的关联，但尚不清楚类似的关系是否延伸到种间水平。由于种间认知差异已被证明是生态和生活史的功能，这种差异应反映在包括慢-快认知轴的多个性状中。在这项研究中，通过测量个体的多种认知特征，我们测试了四种蜜蜂之间认知表型的差异，这些蜜蜂的行为和生活史不同，其筑巢生态的差异与它们的行为和生活史有关。我们的研究结果表明，一组认知特征在每个物种中始终是协变的，导致缓慢和快速的认知表型，在很大程度上满足速度-准确性权衡的预测。我们还发现，这四个物种组成两个不同的集群上的慢-快的认知轴，虽然他们的位置不符合已知的差异，在他们的生活史和筑巢生态。相反，我们发现这四个物种之间的认知差异与它们的大脑大小有关。我们讨论了这些结果对生态学在慢-快认知差异和认知进化中的作用的可能影响。
Slow–fast behavioral and life history differences have been tied to slow–fast variation in cognition that is part of the general speed-accuracy tradeoff. While there is growing evidence for such cognitive variation and its association with behavior and life history at the intraspecific level, it is unknown if a similar relationship extends to the interspecific level. Since interspecific differences in cognition have been shown to be a function of ecology and life history, such differences should be reflected in multiple traits that comprise the slow–fast cognitive axis. In this study, by measuring multiple cognitive traits in individuals, we tested for differences in the cognitive phenotype among four honeybee species, which differ in their behavior and life history in a manner that is associated with differences in their nesting ecology. Our results indicate that a set of cognitive traits consistently covary within each species, resulting in slow and fast cognitive phenotypes that largely meet the predictions of the speed-accuracy tradeoff. We also find that the four species group into two distinct clusters on a slow–fast cognitive axis, although their positions do not align with the known differences in their life history and nesting ecology. We instead find that cognitive differences among the four species are correlated with their brain size. We discuss the possible implications of these results for the role of ecology on slow–fast cognitive differences and the evolution of cognition.
