Simply put the parasitic relationship is +-, the commensal relationship is
+0 and the mutual relationship is ++. The + means fitness or benefit
inceases where - means these decrease. 0 means no effect. Minkoff's text (p.
157) discusses population increases versus decreases and the Lotka-Volterra
equations.
I don't know how easily these relationships can be parsed in nature.
