Fig. 6: Relationship of the probability density of occurrences of Dictyocaryum, Alnus, and Hedyosmum in the northern Andes. Occurrence data for Ecuador, Peru and Bolivia were extracted from the Global Biogeographic Information Facility (8/13/2024) and probability densities are shown relative to the percentage of modern pollen for those taxa across elevations from 500 to 4000 m.

Dotted line indicates the elevation of Lake Cormorán, and the star marks the modern pollen abundance of that taxon at Cormorán.
