Parallel Evolution of Tetrodotoxin Resistance in Three Voltage-Gated Sodium Channel Genes in the Garter Snake Thamnophis sirtalis
Members of a gene family expressed in a single species often experience common selection pressures. Consequently, the molecular basis of complex adaptations may be expected to involve parallel evolutionary changes in multiple paralogs. Here, we use bacterial artificial chromosome library scans to investigate the evolution of the voltage-gated sodium channel (Nav) family in the garter snake Tham...
متن کاملConspecific trailing behaviour of red-sided garter snakes, Thamnophis sirtalis parietalis, in the natural environment
The ability of animals to orient based on pheromonal cues in the environment can have significant consequences to their reproductive success and survival. For example, it is hypothesized that snakes use pheromone trails to locate potential mates during the breeding season and to locate winter hibernacula. Numerous studies have demonstrated that snakes are capable of detecting and following pher...
متن کاملMale red-sided garter snakes, Thamnophis sirtalis parietalis, determine female mating status from pheromone trails
Recently mated females of some species experience a refractory period following mating during which a physiological change or a mating plug prevents remating. Males that determine female mating status from a distance will minimize time spent searching for mates by avoiding unavailable females. Female redsided garter snakes experience a refractory period after mating due to a mating plug. Female...
متن کاملMechanisms and consequences of sexual conflict in garter snakes (Thamnophis sirtalis, Colubridae)
Red-sided garter snakes (Thamnophis sirtalis parietalis) court and mate in early spring around large communal overwintering dens in central Manitoba. Emerging females are immediately covered by dozens or hundreds of vigorously-courting males, potentially imposing significant costs to the female. By manipulating numbers of courting males (both directly and by applying anticourtship pheromones), ...
متن کاملPhysiological Cycles in the Red - Sided Garter Snake ( Thamnophis sirtalis
Red-sided garter snakes (Thamnophis sirtalis parietalis) exhibit a dissociated reproductive pattern in nature: Male snakes court and mate with females after emergence from hibernation, when the gonads are regressed and not producing gametes or sex steroid hormones. The proximate environmental cues used for timing this behavior appear to be the onset of warm ambient temperatures after prolonged ...
