Relationships between 5 traits of 17 bat taxa and four forest structure and two fire regime variables based on (a) fourth‐corner regression and (b) RLQ analysis. In the fourth‐corner regression (a), the strength and direction of relationships between traits (y‐axis) and forest structure and fire regime variables (x‐axis) is indicated by color (red: positive and blue: negative). For example, in the fourth‐corner regression (a), bats with longer duration calls are associated with higher burn severity. In the RLQ analysis (b), the x‐axis shows eigenvalues for Axis 1 and the y‐axis shows five bat traits (purple), four forest structure variables (green), and two fire regime variables (yellow). The strength and direction of Axis 1 eigenvalues of the RLQ analysis (b) indicate how traits covary with forest structure and fire regime variables. For example, in the RLQ analysis (b) open‐adapted bats were most strongly associated with frequent fires (FRI frequent)
