Table 1 Summary of significant effects detailed in Supplementary Tables S1S3, obtained from lineal models adjusted for life-history traits: density, robs, rpot and resting eggs produced by B. ‘Nevada’ and B. quadridentatus.

From: Life-history strategies in zooplankton promote coexistence of competitors in extreme environments with high metal content
