Red-sided Garter Snake (Thamnophis sirtalis parietalis)
Gas chromatograph of a typical female pheromone sample
Methyl ketone ratios change during the summer
in the field but not in the lab
Ultraviolet radiation causes qualitative changes in the skin lipid profiles of red-sided garter snakes
Does ultraviolet-B radiation have an effect on the female sexual attractiveness pheromone?
Full-spectrum light only
Full-spectrum and UVB light
* p < 0.05
p = 0.00934
p = 0.00934
Does ultraviolet-B radiation have the same effect on the female sexual attractiveness pheromone when in mixture with other skin lipids?
Full spectrum light only
Full spectrum and UVB light
Does exposure to ultraviolet-B radiation have an effect on the behavior of red-sided garter snakes?
Short-term: detection and/or avoidance of UVB light
Long-term: snake activity levels
% snakes active, alert, or resting
What effects does daily exposure to ultraviolet-B radiation have on the neutral skin lipids of red-sided garter snakes?
