Supplementary material

Table S1. Resistance values assigned to vegetation cover types (INEGI, Series V).

The values range from 1 (minimum resistance) to 100 (maximum resistance).

Table S2. Resistance categories based on altitude ranges (masl).

The biotic association values (epsilon) and the frequency distribution by suitability deciles were estimated using the algorithm of the SPECIES platform (Stephens et al., 2019).

Figure S1. Network of potential interactions between Bursera linanoe (La Llave) Rzed., Calderón & Medina and species of the Tyrannidae family inferred from spatial association.

Blue points: Bursera linanoe records. Source: obtained from Global Biodiversity Information Facility (GBIF, 2021).

Figure S2. Records of Bursera linanoe (La Llave) Rzed., Calderón & Medina occurrences utilized to model its potential distribution.

Figure S3. Principal component analysis (PCA) of allele frequencies using the Adegenet package.

Figure S4. Mantel test comparing the genetic and geographic Euclidean distances among four Bursera linanoe (La Llave) Rzed., Calderón & Medina populations.

Each vertical bar represents an individual, and the colors indicate the estimated proportion of membership in each genetic group (K). The results are shown for K=3 (top) and K=4 (bottom).

Figure S5. Genetic structure of four Bursera linanoe (La Llave) Rzed., Calderón & Medina populations inferred using a Bayesian ancestry model.

The colors indicate the probability of belonging to each genetic group.

Figure S6. Geographic location of the sampled populations of Bursera linanoe (La Llave) Rzed., Calderón & Medina and spatial distribution of Bayesian ancestry coefficients.

Table S3. Values of the ε statistic and spatial co-occurrence parameters between Bursera linanoe (La Llave) Rzed., Calderón & Medina and species of the Tyrannidae family.

nij = Number of cells where the focal species and the species under evaluation co-occur; nj = Number of cells containing the species under study; ni = Number of cells containing the focal species (Bursera linanoe); n = Total number of cells analyzed (cach cell=16 km²); Epsilon = Spatial association statistic; positive values indicate greater co-occurrence than would be expected at random.
