摘要: Background. In many species, males have a lower reproductive investment than females and are therefore assumed to increase their fitness with high number of matings rather by being choosy. However, in bi-parental also heavily invest into reproduction. Here, success largely depends on costly parental care; style amount effort several cases associated personality differences (i.e., consistent between-individual behaviour). Nonetheless, very little is known about the effect (male) mate choice species. Methods. present study, we tested male for level consistency female boldness rainbow krib, Pelviachromis pulcher, territorial West African cichlid. Individual was indicate quality because it affects defence behaviour. For all females, assessed twice as activity under simulated predation risk. Mate trials were conducted two steps. First, let observe expressing boldness. Then, could choose between these standard test. Results. We preference behavioural (dis-)similarity vs. directional but our data support absence effects and/or (level consistency) mating preference. Discussion. Our results suggest may not be selected via choice.
