Increased niche marginality during LGM for most taxa except
for highland northern clades
When assessing the change in centroid-based niche marginality between
LGM and present, a significant effect was detected for the interaction
between time and clade location (Supporting Information). In general, a
decrease in marginality towards present day was detected for most
highland and lowland clades (Figure 3), and three highland southern
clade outliers (Pinus cembroides , Elgariapauciarinata and Plestiodon lagunensis ) showed a
strong decrease (Supporting Information). Five highland northern and two
lowland southern clades showed an increase in centroid niche marginality
to present day (black labels, Figure 3).
