Abstract

A principal-component scheme was applied to a set of 10 physical, chemical, and biological attributes, measured in 42 samples collected from ‘Los Matadores’ pond (May 1974–July 1975). The first three components account for 82.1% of the total variance in the data and represent the lotic influence (58.3% of the variance), the seasonal cycle (16.4%), and the degree of maturity (7.4%).
