    　View Summary

    The phenomenon of promoting or inhibiting the growth of individuals of conspecifics or other species through the release of chemical substances is called allelopathy, and there are many examples of this phenomenon in plants. On the other hand, in animals, most of the known examples of suppression of other individuals through the release of chemicals into the environment are limited to intraspecific interactions such as social insects. Adult female mosquitofish are reported to release water-soluble chemicals that inhibit growth and reproduction in conspecific females, but the effects of these chemicals on other species were unknown. The results of this study suggest that water-soluble chemicals released by adult female mosquitofish may negatively affect juvenile growth and adult reproduction in the conspecific, as well as reduce survival of juveniles of other species (guppies).
