| intersexual allometry differences and ontogenetic shifts of coloration patterns in two aquatic turtles, graptemys oculifera and graptemys flavimaculata. | coloration can play critical roles in a species' biology. the allometry of color patterns may be useful for elucidating the evolutionary mechanisms responsible for shaping the traits. we measured characteristics relating to eight aspects of color patterns from graptemys oculifera and g. flavimaculata to investigate the allometric differences among male, female, and unsexed juvenile specimens. additionally, we investigated ontogenetic shifts by incorporating the unsexed juveniles into the male an ... | 2015 | 26078863 |
