“…In addition, episodes where choice is ineffectual could reduce the depletion of genetic variation that is predicted under the lek paradox (Kirkpatrick & Ryan 1991), and hence contribute to its explanation (Kokko & Heubel 2008). Alternatively, if the primary cue used in choice is unreliable under some conditions, then females may redirect their attention to alternative cues (Greenfield & Rodriguez 2004;Cotton et al 2006). There remains little consensus on why sexual signalling often involves multiple ornaments ( Johnstone 1996;Candolin 2003), but the use of backup signals when the main cue is rendered unreliable represents one possibility.…”

“…Strong GEIs, such as those that result in ecological crossover, have been identified as being likely to disrupt the reliability of signals of male quality (Greenfield & Rodriguez 2004). In our model, we assume only a weak Table 2.…”

“…Bitton et al 2007;Chapter 5), and females of most species appear to gain only paternal genes from extra-pair fertilizations, it is generally assumed that more elaborately ornamented males are of higher genetic quality, and should in turn sire offspring of higher quality. However, gene-by-environment interactions (GEI) may render male indicator traits unreliable by generating environmentally-contingent phenotypes (Greenfield and Rodriguez 2004), and female multiple mating has been suggested to be a response to this signal unreliability (Yasui 1998). Despite this, there have been few tests, particularly under experimentally manipulated rearing conditions, of the reliability of male ornamental traits as signals of genetic quality, and the linkage between these traits and offspring quality.…”
