在不断变化的环境中，学习和记忆对动物的生存和繁殖至关重要。环境在形成学习和记忆中所起的作用现在引起了相当大的关注。到目前为止，研究倾向于比较两个或最多几个物种的行为，但种间比较可能会产生误导，因为除了环境之外，许多生活史变量可能在物种之间存在差异。在这里，我们报告了一项实验，旨在确定学习如何在同一物种的不同种群之间变化，三棘鱼。我们发现，在解决空间任务的能力，也在他们使用的空间策略的人群之间的差异。第二个简单的学习任务表明，这些差异不是学习能力或适应实验室条件的总差异的结果。我们讨论了这些结果，并建议的行为差异可能涉及到的功能，从鱼的采样各自的栖息地。
In a changing environment, learning and memory are essential for an animal's survival and reproduction. The role played by the environment in shaping learning and memory is now attracting considerable attention. Until now studies have tended to compare the behaviour of two, or at best a few species, but interspecific comparisons can be misleading as many life history variables other than environment may differ between species. Here we report on an experiment designed to determine how learning varies between different populations of the same species, the three-spined stickleback. We found differences between the populations in their ability to solve a spatial task and also in the spatial strategies they used. A second simple learning task showed that these differences were not the result of gross differences in learning ability or adaptation to laboratory conditions. We discuss these results and suggest that the behavioural differences may relate to features of the respective habitats from which the fish were sampled.
