Fig. 5From: Estimation of estuarine habitat degradation and its influence on the reproduction process of the crab Eriocheir sinensis in the Yangtze River EstuaryResults of the RDA and VPA displaying significant predictors of the species–habitat–environment linkages. Displayed are the first and second extracted axes. a The RDA based on HDI accounted for 60.6% (the eigenvalue of first axes) of the variance in the determinant reproductive variables. b The RDA based on HDI accounted for 39.0% of the variance in the environmental variables. c The RDA based on first canonical axe of environmental factors (SAL and NTU were main contributors) accounted for 59.8% of the variance in determinant reproductive variables. d The VPA based on the three groups accounted for 65.8% of the variance in the determinant reproductive variablesBack to article page
