Negative slope values indicate increase from north to south (latitude) or east to west (longitude); positive values indicate a reverse direction of increase; significant p-values before Bonferroni correction (p-value of 0.0033) are shown in italic, and after Bonferroni correction in bold. All YHGs with (marginally) significant p-values are shown in bold
