The reproductive traits of males are under influence of sexual pressures before and after copulation.
The strength of sexual selection varies across populations because they undergo varying competition for mating opportunities.
Besides intraspecific pressures, individuals seem to be subjected to pressures driven by interspecific interactions in sympatry.
Lizards may vary their reproductive strategies through varying sexual characters, body size, gonadal investment, and sperm traits.
We evaluated the reproductive traits, involved in pre- and postcopulatory competition, in allopatric and sympatric populations of Salvator lizards.
We observed a spatial gradient of male competition among populations, with the following order: allopatric zone of S.
rufescens; sympatric zone; and allopatric zone of S.
merianae.
Accordingly, variation in secondary sexual character, the relative testis mass, and the length of sperm component was observed between allopatry and sympatry in each species, suggesting differences in the investment of reproductive traits.
However, we found that these two Salvator species did not differ in secondary sexual characters in sympatry.
Interestingly, the trade-off between testes and muscle varied differently from allopatry to sympatry between these Salvator species, suggesting that the influence of social context on reproductive traits investment would affect lizard species differently.
