Figure 3. Structural Equation Model (SEM; Annex A ) applied to the variables Breeding Bird Species Richness (BBSR) and Wintering Bird Species Richness (WBSP), taking into account: a)the Energy-Landscape Integrated Analysis (ELIA ), and b)the ELIA components (Energy Storage, E ; Energy Information, I , and Landscape Complexity, L ). We have included Landscape Composition (Cm; in a and b ) and Landscape Configuration (Cn; only in a , because in bwe have included L using Principal Component Analysis (Table 1 ).
