The cost of display in the non-resource-based mating system of the satin bowerbird
Article Abstract:
The cost of display has emerged as an important theme in some of the recent discussions of models that attempt to explain the evolution of exaggerated sexual display traits in males of various species. Comparative and experimental information from an eight-year field study of the satin bowerbird, Ptilonorhynchus violaceus, is used for testing the predictions from sexual selection models that focus on the cost of male display. The results suggest that for some cases male displays are not expensive and this may also explain how these displays evolve.

Roamers and stayers: a model on male mating tactics and mating systems
Article Abstract:
An evolutionarily stable strategy model is developed for predicting mating systems in animal population. The variables in the model are the efficiency of male mate-searching, the number of available females within the male's territorial range, the length of the pairing season, the length of the female's estrous period, the sex ratio of the population and the probability of the stayer winning over an intruder. The multifactorial model can be used to analyze male mating tactics in a population of stationary female and staying and roaming males.

Variation in male mating success on leks
Article Abstract:
A study of 20 species of leks to investigate the variation in male mating success within the population, shows a high skew with 10% to 20% of the males involved in 70% to 80% of the mating. Increase in average male mating success results in increase of expected variation in mating success. Individual females are affected in their mate choice by the behavior of other females.
