You can explore real data, and reach your own conclusions about how animal numbers are inter-related and change through time. Data is from the Hinkley Point 'B' power station, Severn Estuary, UK


Dynamica features:

Monthly abundance estimates of fish and crustaceans from January 1981 to January 1995.
Time series for more than 100 species are available for study.
Contains environmental data such as temperature, salinity and tides.
Food webs that change through time.
Statistics allow you to explore the complex inter-relationships between species and environmental factors.
Length data for the common species of fish.
Scientific papers from this data
Details about data collection and habitat are also given.


The strong theme running through Dynamica is the study of community-level dynamics. Books often portray communities and food webs as static entities. This program will show you just how dynamic food webs are. Perhaps the most popular community statistic is a diversity index; Dynamica will let you compare different indices and appreciate how they change through time.




Dynamica has been designed to be useful to anyone with an interest in natural time series. It presents a range of elementary techniques for time series analysis, including data transformations, autocorrelations, moving averages and Fourier analysis. The program presents a wide range of natural dynamic behaviours which make good examples for study.
