Figure 1: Schematic overview of the environmental proxies analysed in Sierra Nevada alpine wetlands.
From: Holocene geochemical footprint from Semi-arid alpine wetlands in southern Spain

Solid lines represent environmental signals with high influence in the proxies (high sensitivity to these signals); dashed lines represent environmental signals with medium influence in the proxies (moderate sensitivity to these signals).
