Choosy outsiders? Satellite males associate with sexy hosts in tthe European tree frog Hyla arborea.
Original language description
In many frog species there is a strong bias in mating success towards larger, more competitive males as a result of female preference for some male attribute related to social status or competitive ability. Less successful males attempt to increase theirreproductive success by adopting alternative mating tactics. We investigated the behaviour of satellite males in the European tree frog Hyla arborea, specifically the relationship between size and mating tactics of males and if the association of satellite males with callers is accidental or size-dependent. Our results show that smaller males become satellites more often than larger males and that calling males associated with satellites are significantly larger than males with no satellites around them. These results suggest that males have good information about their competitors and hence their own mating opportunities and use this information to choose the most successful reproductive tactic available, and that satellite males asso
