Giant Gartersnake (Thamnophis gigas) Prey Preference (2014)

May 12, 2022

This is an examination of the diet of a threatened snake, giant gartersnake (Thamnophis gigas). Prey preference, prey selection and prey availability (in the laboratory and the field) were measured to understand prey dynamics for better conservation of this snake. In the laboratory, olfactory trials were performed on neonate snakes and tongue-flicks, lounges and attacks were counted and calculated into 'tongue-flick attack scores', a measure of prey preference. Prey-choice trials were used to measure prey selection in the laboratory. In the field, we measured prey choice and prey availability to gain an understanding of prey choice in nature.
