Fig. 1 in Explaining mammalian abundance and elevational range size with body mass and niche characteristics

Fig. 1.—Alternative path models used in phylogenetic path analysis to assess the relationships among body mass (MASS), niche breadth (NB), niche position (NP) on mean abundance (ABD) and elevation range size (ER) of species. The hypothesized relationships among variables are described via regression formulas shown at the top of each model and depicted by the direction of the arrows.
