Chesson's Index refers to a lookup table of feeding selectivity described by Jean Chesson in the early 1980s.[1] This index is intended to show whether a preference for a food item or resource exists by comparing the availability and use of that food item. The use of this index has been widespread with more than 400 citations in the scientific literature.[2]
