Phylogenetic Patterns of Sexual Size Dimorphism in Turtles and Their Implications for Rensch’s Rule
Sexual size dimorphism (SSD) is widespread in nature and may result from selection operating differentially on males and females. Rensch’s rule, the increase of SSD with body size in male-biased-SSDExpand

The Role of Sex-specific Plasticity in Shaping Sexual Dimorphism in a Long-lived Vertebrate, the Snapping Turtle Chelydra serpentina
Sex-specific plasticity, the differential response that the genome of males and females may have to different environments, is a mechanism that can affect the degree of sexual dimorphism. TwoExpand

Divergent Sex-Specific Plasticity in Long-Lived Vertebrates with Contrasting Sexual Dimorphism
Sex-specific plasticity can profoundly affect sexual size dimorphism (SSD), but its influence in female-larger-SSD vertebrates remains obscure. Theory predicts that sex-specific plasticity may driveExpand

Patterns of sexual size dimorphism in Chelonia: revisiting Kinosternidae
Rensch's rule, a macroevolutionary pattern in which sexual size dimorphism (SSD) increases with body size in male-biased SSD species, or decreases with female-biased SSD species, has beenExpand

Trachemys medemi n. sp. from northwestern Colombia turns the biogeography of South American slider turtles upside down
South America was invaded by slider turtles (Trachemys spp.) twice, with one immigration wave estimated to have reached South America 8.6–7.1 million years ago (mya) and a second wave, 2.5–2.2 mya.Expand

Effects of Incubation Temperature on Sex Determination in the Endangered Magdalena River Turtle, Podocnemis lewyana
Abstract In species with temperature-dependent sex determination, the embryo commits to its sexual fate during a time window called the thermosensitive period (TSP). Although substantial research hasExpand

HISTOLOGICAL DESCRIPTION OF THE REPRODUCTIVE SYSTEM OF MALE AND FEMALE HATCHLINGS OF THE MAGDALENA RIVER TURTLE (Podocnemis lewyana)
In this study we review the macro and microscopic description of the reproductive system of male and female Podocnemis lewyana neonates of 3.5 months of age. We found macroscopic differences in theExpand
