Abstract
A set of environmental variables from a coastal salt pond were regressed in a stepwise fashion against the following dependent variables: phytoplankton standing crop, species diversity and dominance. Multiple variable interaction, as measured by multiple correlation coefficients yielded higher values than the coefficients obtained by regressing individual environmental variables against the dependent variables. The seasonal variation in the dependent variables could, therefore, be explained to a greater extent by the effects of multiple variables rather than single limiting factors.
