动物可以利用社会传递的信息来了解资源的分布和质量，而不必承担与第一手搜索和采样相关的成本。最近，它已被证明，使用特定的饮食和栖息地利用模式的化学社会信息是一个重要的机制，支持识别和社会组织在浅水鱼类。在这项研究中，我们揭示了资源特定化学信息的使用不仅限于同种，甚至不限于同一分类单元的成员。（Gasterosteus aculeatus）可以识别出普通对虾的栖息地利用模式（Leander serratus），优先面向群体的对虾暴露在相同的栖息地，因为自己，甚至选择觅食补丁位于靠近他们。大虾被认为是使用特定的栖息地产生的同种线索，但不是由刺鱼，这表明形成这些异种社会协会模式的好处可能是不平等的对虾和鱼类。我们的研究结果表明，一些物种可能会使用共同出现的，无关的物种作为信息中心，以定向和定位资源在其周围环境。
Animals can use socially transmitted information to learn about the distribution and quality of resources without incurring the costs associated with having to search for and sample them first hand. Recently, it has been shown that the use of chemical social information specific to patterns of diet and habitat use is an important mechanism underpinning recognition and social organization in shoaling fishes. In this study we revealed that the use of resource-specific chemical information is not limited to conspecifics, or even members of the same taxon. In a series of laboratory experiments, we showed that threespine sticklebacks (Gasterosteus aculeatus) could recognize similar patterns of habitat use in common prawns (Leander serratus), preferentially orientating towards groups of prawns exposed to the same habitats as themselves, and even selecting foraging patches located close to them. Prawns were seen to use habitat-specific cues generated by conspecifics, but not by sticklebacks, suggesting that the benefits of forming these heterospecific social association patterns may be unequal for prawns and fishes. Our findings suggest that some species might use co-occurring, unrelated species as information centres in order to orient and locate resources within their surroundings.
