    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.
