Make love not war: when should less competitive males choose low-quality but defendable females?. Venner, S., Bernstein, C., Dray, S., & Bel-Venner, M., C. The American Naturalist, 175:650-661, 2010. abstract bibtex Male choosiness for mates is an underexplored mechanism of sexual
selection. A few theoretical studies suggest that males may exhibit
-but only under rare circumstances- a reversed male mate choice (RMMC;
i.e., highly competitive males focus on the most fecund females,
while the low‐quality males exclusively pair with less fecund mates
to avoid being outcompeted by stronger rivals). Here we propose a
new model to explore RMMC by relaxing some of the restrictive assumptions
of the previous models and by considering an extended range of factors
known to alter the strength of sexual selection (males’ investment
in reproduction, difference of quality between females, operational
sex ratio). Unexpectedly, we found that males exhibited a reversed
mate choice under a wide range of circumstances. RMMC mostly occurs
when the female encounter rate is high and males devote much of their
time to breeding. This condition‐dependent strategy occurs even if
there is no risk of injury during the male‐male contest or when the
difference in quality between females is small. RMMC should thus
be a widespread yet underestimated component of sexual selection
and should largely contribute to the assortative pairing patterns
observed in numerous taxa.
