Is there an overriding principle of nature, hitherto overlooked, that governs
all population behavior? A single principle that drives all the regimes
observed in nature - exponential-like growth, saturated growth, population
decline, population extinction, oscillatory behavior? In current orthodox
population theory, this diverse range of population behaviors is described by
many different equations - each with its own specific justification. The
signature of an overriding principle would be a differential equation which, in
a single statement, embraces all the panoply of regimes. A candidate such
governing equation is proposed. The principle from which the equation is
derived is this: The effect on the environment of a population's success is to
alter that environment in a way that opposes the success.Comment: Revised equation-numbering to correspond to published versio
