Abstract:
A contrastive analysis is made of the frog and cricket phenological phases from 1989 to 2007 and meteorological data from 1975 to 2007 in the northern Guangxi. The results indicate that the dates of beginning chirps of frogs and crickets exhibited an advancing trend; those of ending chirps kept unchanged, and the beginningending intervals had an obvious extending trend. The mean annual temperature presented a markedly increasing trend in the last 34 years in the Yanshan Mountains, especially in the last 10 years, mainly in spring. The FebruarytoApril mean temperature and March mean maximum temperature are the main climatic factors that impact the dates of beginning and ending chirps of frogs and crickets and the intervals. The changes of animal phenology are the responses of animals to climate warming.
