Many species across taxa select habitat based on conspecific presence, known as conspecific attraction. Studies that document conspecific attraction typically provide social information (i.e., cues that indicate the presence of a given species) and then determine if a given species is more likely to settle at locations where the social information is provided compared to those locations that do not. Although the number of studies examining conspecific attraction has grown in recent years, a comprehensive review has not yet been undertaken. Here, we conducted a review of the literature and found 151 studies investigating conspecific attraction across eight taxa. We found that conspecific attraction is widespread with between 80% and 100% of studies, depending on taxa, documenting positive associations between habitat selection and the presence of conspecific cues. Conspecific attraction has been documented more frequently in bird and fish species with less attention given to invertebrate and mammal species. We use the patterns we found to (a) provide an overview of the current state of research on conspecific attraction and (b) discuss how important factors, such as cue characteristics and life history traits, may play a role in shaping conspecific attraction patterns within and across taxa.
许多不同分类群的物种会根据同种个体的存在来选择栖息地，这被称为同种吸引。记录同种吸引的研究通常会提供社会信息（即表明特定物种存在的线索），然后确定与未提供社会信息的地点相比，特定物种是否更有可能在提供了社会信息的地点定居。尽管近年来研究同种吸引的研究数量有所增加，但尚未进行全面综述。在此，我们对文献进行了综述，发现有151项研究调查了八个分类群中的同种吸引。我们发现同种吸引很普遍，根据分类群的不同，80%到100%的研究记录了栖息地选择与同种线索存在之间的正相关关系。同种吸引在鸟类和鱼类物种中记录得更为频繁，而对无脊椎动物和哺乳动物物种的关注较少。我们利用所发现的模式（a）概述同种吸引的当前研究状况，以及（b）讨论重要因素，如线索特征和生活史特征，如何可能在塑造分类群内部和之间的同种吸引模式中发挥作用。
