Animal body size commonly shows a relationship with latitude to the degree
that this phenomenon is one of the few ‘rules’ discussed in evolutionary
ecology: Bergmann's rule. Although exaggerated secondary sexual
traits frequently exhibit interesting relationships with body size
(allometries) and are expected to evolve rapidly in response to
environmental variation, the way in which allometry might interact with
latitude has not been addressed. We present data showing latitudinal
variation in body size and weapon allometry for the New Zealand giraffe
weevil (Lasiorhynchus barbicornis). Males display an extremely elongated
rostrum used as a weapon during fights for access to females. Consistent
with Bergmann's rule, mean body size increased with latitude. More
interestingly, weapon allometry also varied with latitude, such that lower
latitude populations exhibited steeper allometric slopes between weapon
and body size. To our knowledge, this is the first study to document a
latitudinal cline in weapon allometry and is therefore a novel
contribution to the collective work on Bergmann's rule and secondary
sexual trait variation.
