Location of the study area in southeast Australia.
The enlarged detail shows a single dry-forest landscape sampling unit of 100 ha (1.13 km diameter). Modified from Sitters et al. [52] under a CC BY license, with permission from Elsevier Ltd., original copyright 2014.
Table 1.
Responses of bird species richness and functional diversity to vertical (VD) and horizontal vegetation diversity (HD) in different forest types (FT) and years (Y) derived from linear mixed models.
Fig 2.
Responses of species richness and functional diversity to vegetation diversity indices.
Predictions and 95% confidence intervals are derived from top-ranked linear mixed models. Point colours and line types correspond to different forest types (dry forest = grey points, dotted lines; wet forest = black points, dashed lines). Lines corresponding to year 1 (grey) and year 2 (black) are displayed where year had a significant influence on the response variable.
Fig 3.
Fourth-corner interaction coefficients for the relationship between bird traits and vegetation structure variables.
Statistically significant relationships are indicated in red (positive) and blue (negative); the shade of the colour represents the strength of the association. Clutch size is an ordinal variable, mass is continuous and other trait variables are categorical.
Fig 4.
Responses of vertical and horizontal diversity to the mean and diversity of the time since fire index (TSF).
Predictions and 95% confidence intervals are derived from top-ranked linear mixed models. Point colours and line types correspond to different vegetation types (dry forest = grey points, dotted lines; wet forest = black points, dashed lines).

Responses of vegetation diversity to the mean (TSFm) and diversity (TSFd) of the time since fire index in different forest types (FT) and years (Y) derived from linear mixed models.
