Fig. 2: Floristic diversity across time in southern Patagonia.
From: Impact of mid Eocene greenhouse warming on America’s southernmost floras
a Within-sample richness (coverage level= 0.8) with bootstrapped 95% confidence intervals and b evenness for pre-MECO (green), MECO (dark-orange) with three subgroups and post-MECO (yellow) samples against the composite section of the Río Turbio Formation (see references in Supplementary Fig. 1). Vertical bars in a denote mean diversity within each major group of samples (or intervals) detected from the constrained cluster analysis (c). See Table 1 for further details. Arrows at the Stage column indicate major dinocyst events from the sampled composite section of the Río Turbio Formation; (1) Lowest Occurrence of E. dictyostila; (2) Lowest Common Occurrence of E. dictyostila; (3) Lowest Common Occurrence of T. filosa; (4) Highest Occurrence of T. filosa; (5) Highest Common Occurrence of E. dictyostila . See Supplementary Fig. 5 for further details.
