Fig. 6: Hotspot analysis based on spatio-temporal distribution of Sunda Shelf connectivity.
From: Quaternary landscape dynamics boosted species dispersal across Southeast Asia
a and c Getis-Ord (Gi⋆) index obtained by stacking temporal hot and cold spot analysis of current flow fields over multiple time steps. Red regions correspond to hotspot areas where computed connectivity from geomorphological features is high and favours species migration. b and d Pie chart presenting percentages of the shelf hot/cold spots. The hotspot category is sliced based on normalised stacked Gi⋆ from warm (normalised from 0. to 0.25) to hot (from 0.75 to 1). e Boxplots displaying the distribution of normalised stacked Gi⋆ for four different elevation bands. Each boxplot shows the minimum, first quartile (Q1), median, third quartile (Q3), and maximum for each band.
