Differences in timing and degree of overlap between adult emergence from the experimental population and pheromone trap catches suggests that the spring population of this species also includes immigrants.
Although the timing of amphibians' spring emergence following winter dormancy may vary under the influence of climate change, the behavior of the animals should be more directly a response to the weather and/or other immediate stimuli and may be expected to show some population-level consistencies independent of timing. As such, there should be particular conditions of temperature.
