Summary of behaviour of individual bird species used as response variables [33]–[35].
Table 2.
Subset of explanatory variables used in final models where fpc = foliage projected cover, gc = ground cover, cov = coefficient of variation, long term = 20 years and short term = 5 years.
Table 3.
By species, final set of parameters with the best fit under each conceptual model.
Table 4.
Ranking order of model performance for each response variable according to Akaike weight (in brackets).
Figure 3.
Model averaged parameter estimate of explanatory variables for each response variable under model 4 (the temporal-spatial heterogeneity model).
The greater the parameter estimate the larger the comparative influence on the response variable. Black bars represent site scale variables, grey bars landscape scale and white bars time series variables.
