Table 1.
Overview of characteristics of the different research areas, with the name and size of the reserve, the average rainfall per year, the number of years from which complete data is available for analysis, and whether the reserve has open borders to Kruger National Park.
Table 2.
All measured manifest variables used in the analyses with abbreviations and dimensions.
Fig 1.
Initial total path model and used total path model.
(a) The initial path model with all manifest variables which could describe the latent variables. (b) The final path model after removing manifest variables. Goodness of fit = 0.49. Circles show the latent variables and squares show the manifest variables. Arrows between latent variables indicate interactions and arrows toward manifest variables show which variables describe the latent variable.
Fig 2.
The final path model for (a) Balule Game Reserve (Goodness of fit = 0.56), (b) Kapama Game Reserve (Goodness of fit = 0.64) and (c) Sabi Sand Wildtuin (Goodness of fit = 0.64) after removing bad manifest variables. Circles show latent variables and squares manifest variables. Arrows between latent variables indicate correlations and arrows toward manifest variables show which variables describe the latent variable.
Fig 3.
Results of the path model for three areas pooled together.
Circles are latent variables and arrows illustrate interactions. Numbers are regression coefficients. * = P<0.05, ** = p<0.01. Girabrowse is browse availability for giraffes and impbrowse is browse availability for impala.
Fig 4.
Results of the path models per reserve.
Results of the path model for (a) Balule Game Reserve, (b) Kapama Game Reserve and (c) Sabi Sand Wildtuin. Circles are latent variables and arrows interactions. Numbers are regression coefficients. * = P<0.05, ** = p<0.01. Girabrowse is browse availability for giraffes and impbrowse is browse availability for impala.
