Identifying environmental versus phylogenetic correlates of behavioural ecology in gibbons: implications for conservation management of the world’s rarest ape

Table 4 Model-averaged home range and group size predictive models: model-averaged fixed effects parameter estimates for: a) HR (from n = 19 model set with ΔAICc < 7 and cumulative w _i >0.95), and b) GS (from n = 10 model set with ΔAICc < 7 and cumulative w _i >0.95), with relative importance (RI) of each parameter
