In populations from Arizona, chorusing activity was initiated independent of recent rainfall and usually occurred for a total of a few weeks each year. In a population of B. m. microscaphus from C Arizona, pulse rate and duration of the advertisement call were significantly correlated with temperature, but frequency was not influenced by temperature over a 5°C range. Temperature-adjusted pulse rate did not vary significantly among the populations, including B. m. californicus. Additionally, for both call duration and frequency, B. m. californicus was not significantly different from two of the three eastern populations of B. m. microscaphus. It appears that these taxa share specific mate recognition systems. -from Author
