Traversing the eastern Georgian Bay rock barrens in search of nesting turtles: Does temperature and moisture have an affect on hatch success?
September 25, 2022Hope Freeman, MSc candidate, McMaster Ecohydrology Lab, School of Earth, Environment and Society, McMaster University
My first experience working with turtles was the summer of 2017, where I volunteered for Grundy Lake Provincial Park’s turtle monitoring program.

Investigating the Enduring Mystery of Temperature-dependent Sex Determination
May 01, 2021Jessica Leivesley, PhD candidate, Njal Rollinson Lab, University of Toronto
In my opinion, temperature-dependent sex determination (TSD) is one of the weirdest but most interesting things about reptiles. In animals, sex determination is typically thought of in terms of sex chromosomes.
