On the correlation of time series in ecology of aquatic systems
Abstract:
A method for estimating the mutual influence of short time series, which is based on extension of the concept of spectral entropy to the spectra of cross-correlation functions is developed. Algorithms of calculations and programs are given. The time series of plankton abundance in the lake ecosystem, which is situated in the Republic of Belarus, are analyzed in order to identify mutual correlations. Correlations between the bacterioplankton abundance and variations in seasonal temperature are identified. The peculiarities of interrelations between the abundances of zooplankton/phytoplankton and temperature depending on the reservoir are analysed.
