Many species have dynamic reproductive strategies that can change in response to changes in the environment. In these instances, several factors contribute to the decision to switch between mating strategies. For example, in the European tree frog, a sexually competitive (as in, perceived to be attractive by females) male tend to call to attract mates.
This explanation explores how various species use flexible reproductive approaches that can adjust in response to environmental changes. When this happens, several factors come into play when deciding whether to switch between mating strategies. For instance, in the European tree frog, a male perceived as attractive to females will vocalize to attract mates.
