the bottom of the pyramid to more existential or self-fulfilment needs at the top of the pyramid. b, Different combinations of plant size and geographic range (PGLS coefficients) underpin the benefits that people derive from nature and the hierarchy of human needs. Plant size is represented as axis one of a principal component analysis on the three functional traits leaf length, fruit volume, and stem volume. Uses – related to basic human needs (e.g., show a significant positive link with both Food) plant size and geographic range (yellow symbols); uses related to psychological needs (e.g., only show a significant link to one of the two traits (blue or red Culture) symbols); and uses related to self-fulfilment needs (e.g., never show Ritual, Cosmetic) significant links to traits (white symbols).
