Abstract
A subset of Stephens & Waggoner's (1970) data, spanning 40 years of recording at the same site, is analysed by AOC for trends in density fluctuations. The results suggest that the recording period is sufficiently long for trends to be detected. A dominant trend depicts density changes as simple monotone functions of time. Other lesser trends signify cyclic changes of different lengths. The fact that a dominant monotone trend exists is interpreted as evidence of succession.
