From: Evolution within a language: environmental differences contribute to divergence of dialect groups
Observed vs predicted linguistic differences between the municipal dialects. Predicted differences between the municipal dialects calculated on the basis of (a) cultural differences (corresponds to fractions b, d, f and g in Fig. 2b), (b) environmental differences (corresponds to fractions a, d, e and g in Fig. 2b), (c) environment-cultural differences (corresponds to fractions a, d, e and g in Fig. 2c), (d) administrative and geographical distances (fractions b, c, d, e, f and g in Fig. 2c). Cultural and environmental features are given in Table 2. Pairing up the 471 municipal dialects resulted in 110,685 linguistic difference values, from which we randomly sampled 5% of the data points for the graphs, leading to N = 5535
