ALT A multi-part infographic featuring two maps showing species richness and range size patterns for ferns and lycophytes: Left Map (Ferns): The areas marked in orange represent regions with high species richness and low ranges (rich-low range areas). Areas in green represent regions with low species richness and high ranges (poor-high range), which are concentrated on the upper and lower limits of the biome. Right Map (Lycophytes): This map follows the same color pattern to depict species richness and range size patterns for lycophytes. Section 2 (bottom-left corner), a graphical illustration shows the drivers of high richness and low range sizes of ferns and lycophytes from the Atlantic Forest. An upward arrow illustrates factors contributing to high species richness. A downward arrow shows factors contributing to small range sizes.
