Ontogenetic variation of plastral spotting pattern in Phrynops hilarii (Testudines, Chelidae)

Abstract: The plastral spotting variation in the chelid turtle Phrynops hilarii (Duméril & Bibron, 1835) in relation to sex, size, and geographic procedence of individuals was analyzed. States for qualitative characters were analyzed using non-parametric tests. Quantitative characters (shell and scute measurements) were standardized for body size by linear regression against carapace length, and were subjected to principal components analysis and canonical discriminant function analysis. Results suggest that increased p… Show more

“…some limitations exist. In chelid turtles, plastral marks might be vulnerable to ontogenetic variation and care must be taken to mark areas that do not change with age (Cabrera and Colantonio 2001). the objective of our research was to record unique characteristics of individual Bokermannohyla hylax, enabling "mark"-recapture population studies of this species.…”
