Abstract

Most Emydidae, including Diamond-backed Terrapins (Malaclemys terrapin), have temperature-dependent sex determination. However, the full relationship between incubation temperature and offspring sex in the Diamond-backed Terrapin has not been reported, and the pivotal temperature, range of transitional temperatures, and the temperature-sensitive period have not been investigated fully. Here we report on these parameters, comparing our data with data from other emydid turtles, and also comparing our laboratory data to field data collected previously for this population.

La mayoría de Emydidae, incluyendo a las Diamond-backed Terrapins (Malaclemys terrapin), tienen determinación de sexo por temperatura. Sin embargo, la relación entre temperatura de incubacion y sexo de crías en el Diamond-backed Terrapin no ha sido reportada, ni el umbral de temperatura ni el período sensible a la temperatura han sido investigados. Aquí reportamos ambos fenómenos y los compararmos con otras Emydidae, asi como con datos de campo de ésta población previamente colectados.
