Traits are sorted into aerobic (heart, gill, CS) and anaerobic (swimming motor, LDH and ATPase) sectors; the initial hypothesis was that factor loadings would correspond to these sectors. ATPase is absent from female PC axes because of unreliable data from one drainage. The combined components explained 60.5% of total variance in females and 54.6% of total variance in males.
