Females commonly incorporate information from more than 1 male trait when making mating decisions, which may increase their ability to choose high-quality males. Assessment of multiple male traits may also incur increasing costs of time and/or energy and should therefore provide an adaptive advantage over females that do not exhibit such complex mating decisions. Although this benefit has been assumed/concluded in previous mate choice studies, it has rarely been empirically verified with female fitness data. Here we show that female side-blotched lizards (Uta stansburiana) that assess males for optimal trait combinations of throat color (a polymorphic social signal) and dorsal patterning (a ..View full abstract
