珊瑚礁上的清洁共生,在那里专门的鱼类从许多种类的客户鱼类身上去除寄生虫,大大增加了我们对互利共生的理解,但我们对清洁工之间重要的种间相互作用知之甚少。在这里,我们探讨了清洁Labroides dimidiatus和Labroides bicolor在两个不同的生命阶段之间的竞争潜力。以前的工作已经证明,与L。dimidiatus,建立清洁站,adult L.双色车在大范围内搜寻客户我们展示了位点附着的青少年。bicolorassociate不同的微生境比juvenileL. dimidiatus和L. bicolor专门研究比L更窄的物种范围。dimidiatusas青少年和成年人。此外,我们提出的证据表明,资源利用的差异是由两个物种之间的竞争相互作用的影响。最后,我们讨论了这些结果对理解生态学和进化的互惠关系的影响。
Cleaner mutualisms on coral reefs, where specialized fish remove parasites from many species of client fishes, have greatly increased our understanding of mutualism, yet we know little about important interspecific interactions between cleaners. Here, we explore the potential for competition between the cleanersLabroides dimidiatusandLabroides bicolorduring two distinct life stages. Previous work has demonstrated that in contrast toL. dimidiatus, which establish cleaning stations, adultL. bicolorrove over large areas, searching for clients. We show that site-attached juvenileL. bicolorassociate with different microhabitat than juvenileL. dimidiatusand thatL. bicolorspecialize on a narrower range of species thanL. dimidiatusas both juveniles and adults. Further, we present evidence suggesting that differences in resource-use are influenced by competitive interactions between the two species. Finally, we discuss the implications of these results for understanding the ecology and evolution of the mutualism.
