Rejection behaviors were used only outside of the receptive period to communicate, to all males, that the female is not receptive.Īndersson, M. Thus, a female appears to mate unselectively within her receptive period. There was no discrimination against any male category regardless of size or color within a female's receptive period and the manipulation of male head color in the natural population did not result in spatial re-distribution of females. Females appeared not to express any kind of active or passive mate choice (rejection) in only one out of 62 trials did a female approach a male herself rather than being approached by the male(s). Blue-headed males were accepted as mating partners both in the staged mating trials and in the natural population. The corresponding manipulations were also made in a free-living population where the distribution of females on the home ranges of color-manipulated males were monitored. The rationale for these experiments was: firstly, to establish if females actively solicit copulations secondly, if so, do females solicit copulations non-randomly with respect to male size (because large males may have access to food resources) thirdly, if male coloration is manipulated to match traits of congeneric, conspicuous and sexually dimorphic species, do females show preference for this novel trait (in accordance with the sensory exploitation hypothesis). ‘small’ males and, in a different experiment, males with ‘blue’ vs. In enclosure trials, females were offered the choice between ‘large’ vs. Aspects of sexual selection were studied in a sexually monomorphic Australian agamid lizard ( Ctenophorus fordi), in particular with respect to the sensory exploitation hypothesis.
