Abstract
I recorded the calling activity of the males of a population of the common eastern froglet Crinia signifera during 1988 to determine the seasonal and temporal patterns of calling activity and the influence of micrometeorological variables on calling. The patterns of calling were recorded using an automated cassette recorder switched on for 10 seconds approximately every 15 minutes. To assess the effects of micrometeorology on calling I compared the mean hourly calling activity with air temperature, barometric pressure, humidity, rainfall and wind intensity with time of day as a co-variable. This comparison was undertaken for data from three separate two-month periods of the year, as well as with the data from the three periods combined, to determine if there were seasonal differences in the effects of micrometeorology. For the analysis I used a forward stepwise Generalised Linear Model. Chorusing was recorded in every month of the year. Time of day was highly significant as a predictor of hourly calling a...
