我们收集了两只虾虎鱼，Apocryptodon punctatusandAcentrogobiussp。A，和来自日本南部河口的四只阿尔菲德虾，以识别与虾虎鱼共生的虾，并了解它们的伴侣特异性和依赖性。基于广义线性模型的分析确定了每个gobya的两个特定伙伴。斑纹虾虎鱼经常与伴侣共存，并表现出相似的栖息地，这表明这种虾虎鱼可能是一种义务性的互惠主义者。A的共存率较低，并且出现在与其伴侣之一不同的栖息地，这表明这只虾虎鱼可能是兼性互惠主义者。
We collected two gobies,Apocryptodon punctatusandAcentrogobiussp. A, and four alpheid shrimps from an estuary in southern Japan, to identify the symbiotic shrimps with gobies and to understand their partner specificity and dependency. Analysis based on generalized linear models identified two specific partners for each goby.A. punctatusfrequently coexisted with partners and showed similar habitats, suggesting that this goby might be an obligate mutualist.Acentrogobiussp. A had lower rates of coexistence and appeared in habitats different from one of its partners, suggesting that this goby might be a facultative mutualist.
