Besides making its hosts sick, a pathogen may also alter the host's behavior. An and Waldman (2016) have found that Japanese tree frogs (Hyla japonica) with natural infections of Batrachochytrium dendrobatidis called longer and made more rapid calls than did uninfected males. This may have two effects, possibly interrelated. Because female frogs are known to be generally attracted to males that call longer and faster, pathogen transmission might be enhanced. Alternatively, the altered calls might result from selection on males for early reproductive success in anticipation of a premature death. However, it is unknown whether Japanese tree frog females prefer infected males.
