It was the aim of this work to investigate the effects of meteorological factors on two types of behavior related to vocalization in two species of anuran amphibians (Bufo calamita and Hyla arborea). The measurements were carried out in two gravel pits in the Kanton of Zurich. Evaluation by multiple linear regression was carried out at the computer Center of Zurich University. It could be shown that water temperature at 1900 was the most important factor for the onset of callings in both species. Air pressure (for both species) and amount of rainfall on the previous day and shunshine on the same day (for Bufo calamita) played a less important but significant role for this type of behavior. In both species, water temperature at 2400 was the important factor for the duration of the mating chorus. In addition, the amount of rainfall on the previous day and sunshine on the same day had a slight but significant effect on this type of behavior in Bufo calamita. The validity of the method and the results are discussed.
本研究旨在调查气象因素对两种无尾两栖动物（绿蟾蜍和雨蛙）与发声相关的两种行为类型的影响。测量在苏黎世州的两个砾石坑中进行。在苏黎世大学计算机中心通过多元线性回归进行评估。结果表明，19:00时的水温是两种物种开始鸣叫的最重要因素。气压（对两种物种而言）以及前一天的降雨量和同一天的日照量（对绿蟾蜍而言）对这种行为类型起到的作用较小但具有显著意义。在两种物种中，24:00时的水温是交配合唱持续时间的重要因素。此外，前一天的降雨量和同一天的日照量对绿蟾蜍的这种行为类型有轻微但显著的影响。文中讨论了该方法和结果的有效性。
