对来自不同生境的三刺刺鱼种群进行了研究，以确定生境是否会影响空间线索的组合能力。之前的研究表明，不同的物种以不同的方式组合空间线索，这项研究表明，这些差异也出现在一个物种内部：所有的鱼都能够使用几何线索来定位迷宫出口，但只有从河流种群中收集的鱼才能将几何线索与非几何全球地标线索结合起来。
Populations of three-spined sticklebacks Gasterosteus aculeatus originating from contrasting habitats were studied to determine if habitat can affect the ability to combine spatial cues. Previous work has shown that different species combine spatial cues in different ways, and this study showed these differences also arose within a species: all fish were able to use geometrical cues to locate a maze exit, but only fish collected from river populations combined geometric cues with a non-geometric global landmark cue.
