To investigate the impact of nuptial coloration (the
badge) on male fitness in the Swedish sand lizard
(Lacerta agilis), we conducted a manipulation
experiment in a natural population. Males in one
group had their badges enlarged by being painted as
cheaters and were compared to a control group with
respect to mate acquisition, body condition and survival.
Badge enlargement did not affect survival, but
elevated mate acquisition by almost 400%, and body
condition in small males. This increase in condition
is likely to stem from greater access to female-associated
sites with high food availability.
