Composite, two-dimensional niche matrix for the 16 bat species from Margarita Island and the 39 species actually captured on the adjacent Venezuelan mainland. The trophic role values are those employed by Wilson (1973) or only slightly modified. The model values for forearm length are those used by Fleming at al., (1972). Each of the 49 cells of the matrix is divided into two parts, the upper represents species (abbreviated scientific names) and trophic role values for the Venezuelan mainland and the lower represents those for Margarita Island. At the left-hand margin appear the importance values (IV) for each trophic role in each of the two regions. The importance values are derived by dividing the total trophic values by the number of bat species in each fauna and expressed as a per- centag
