Temperament and sexual behaviour in the Furrowed Wood Turtle Rhinoclemmys areolata

Area of Science:

• Behavioral Ecology
• Animal Behavior
• Evolutionary Biology

Background:

• Temperament variation significantly impacts animal evolution and ecology.
• Consistent behavioral differences, particularly in chelonians, affect reproductive success.
• Previous studies on turtle temperament utilized diverse methodologies.

Purpose of the Study:

• Establish a reliable methodology to assess boldness in Rhinoclemmys areolata.
• Investigate the role of boldness in turtle reproduction, focusing on courtship and copulation.
• Analyze how boldness influences male-female interactions and male-male competition during reproduction.

Main Methods:

• Observed 16 sexually mature male and female Rhinoclemmys areolata.
• Recorded 17 behavioral traits in males across four distinct situations to identify boldness indicators.
• Assessed courtship and copulation behaviors in male-female pairs and male-male competition scenarios.

Main Results:

• Identified 12 key behavioral traits distinguishing bolder from shier individuals, with five specific to each temperament.
• Bolder males bypassed courtship, attempting direct copulation, while shier males engaged in courtship behaviors.
• In competitive settings, bolder males exhibited courtship, whereas shier males ignored females, indicating context-dependent strategies.

Conclusions:

• Validated a robust methodology for determining turtle temperament and boldness.
• Temperament is a crucial factor modulating reproductive interactions in turtles.
• Bolder and shier males employ distinct, temperament-dependent reproductive strategies influenced by social context and competition.
