This is the study done with fish sexual selection ( polygynous species like us humans) and this is the small part of the article I thought was interesting.
"Male beaugregory preferences may be described by one of the mate choice models proposed for females. Reid and Stamps (1997) reviewed a number of these models and observed that they fell into two general categories: the comparison model and the threshold model. The comparison model predicts that females will select the best male from among a group of available males. The threshold model predicts that females select any male that has a quality above a threshold level.
To apply the comparison model to male beaugregories, we predicted that they would base their preference (i.e., expressed by their courtship intensity and/or selectivity) on the relative quality of their own resource. This requires that they compare the quality of their resource with those of their neighbors. Any quantitative differences in the relative quality of a male's resource will be translated into quantitative changes in his overall courtship intensity and/or selectivity. The threshold model, when applied to beaugregory males, predicts that males require some level of resource quality before modulating their courtship costs and/or selectivity. Any further quantitative differences in the resources above the threshold will have no impact on male courtship"
