Multiple male traits interact: attractive bower decorations facilitate attractive behavioural displays in satin bowerbirds.
Sexually selected male courtship displays often involve multiple behavioural and physical traits, but little is known about the function of different traits in mate choice. Here, we examine female courtship behaviours to learn how male traits interact to influence female mating decisions. In satin bowerbirds (Ptilonorhynchus violaceus), successful males give highly aggressive, intense behaviour...

Here, I test the hypothesis that UV and non-UV colors are important in choice of satin bowerbird bower decorations (colored squares and blue parrot ...
متن کاملMinimax Play at Wimbledon
We use data from classic professional tennis matches to provide an empirical test of the theory of mixed strategy equilibrium. We Þnd that the serve-andreturn play of John McEnroe, Bjorn Borg, Boris Becker, Pete Sampras and others is consistent with equilibrium play. The same statistical tests soundly reject the assumption of equilibrium play in experimental data, including the data from Barry ...
