Phenotypic basis for a feeding change in an insular population of garter snakes.
Predation on birds, an unusual behavior for the common garter snake (Thamnophis sirtalis), has been observed and documented in an insular garter snake population. Feeding preference tests were performed on naive neonatal snakes and experienced adults from both the island test population and a nearby mainland control population. No significant preference for birds as a prey item was found for ei...

متن کاملThe Evolution Arms Race of Garter Snakes and Newts
In evolutionary biology, predator-prey species pairs can be observed participating in evolutionary arms races between adaptations and counter-adaptations. For example, as a prey becomes more adept at avoiding capture, its predator becomes a more adept hunter. The rough-skinned newt (Taricha granulosa) produces a toxin that protects it from virtually all predators, except one. That one predator ...
متن کاملSmall-scale Geographic Variation in Antipredator Tactics of Garter Snakes
Garter snakes (Thamnophis sirtalis parietalis) in Manitoba court and mate at communal overwintering dens and then disperse to feeding ranges in summer. The restriction of mating activities to den areas may reduce gene flow between populations from adjacent dens, in turn allowing divergence in traits such as antipredator behavior. We quantified responses of adult male snakes to the approach of h...
متن کاملScaling the heights: thermally driven arboreality in garter snakes
Occasional use of arboreal habitats is common in many otherwise-terrestrial species, but the functions of facultative arboreality remain unclear. Red-sided garter snakes (Thamnophis sirtalis parietalis) are small nonvenomous terrestrial snakes, recorded to climb only rarely. During springtime fieldwork near a large communal overwintering den in Manitoba, we observed occasional episodes when hun...
