Additional file 1: Calculation of coefficients of harmonic regression for
climate variables and topography in R. Description of data: R script
illustrating the production of the coefficients of harmonic regression for
climate variables and topography.
Additional file 2: Collinearity among the 19 final individual predictor
variables. All final predictor variables had correlation values below 0.7 or
above−0.7. Description of data: The table contains collinearity among
final 19 predictor variables chosen for modelling.
Additional file 3: List of predictor variables indicating their respective
reference codes. Description of data: The table contains a list of all
predictor variables considered for this study and their abbreviations as
reference codes.
Additional file 4: Calculation of the true skill statistic (TSS) for each
replicate of the 10-fold cross-validation from MaxEnt output in R. Description
of data: R script illustrating the calculation of the true skill statistic (TSS) for
each replicate of the 10-fold cross-validation from MaxEnt output.
Additional file 5: Variable importance (i.e. percent relative predictor
variable individual contribution) in MaxEnt models, averaged across flea
species based on (a) microhabitat preference and (b) host specificity (see
Additional file 2 for variable reference code). Significant differences in the
contribution of predictor variables between the two categories of species
are indicated by asterisks: *** P < 0.001, ** P < 0.01, * P < 0.05. Description of
data: The bar plot figure illustrate variable importance (i.e. percent relative
predictor variable individual contribution) in MaxEnt models, averaged
across flea species based on microhabitat preference and host specificity.
