摘要：

A modification of Gladfelter‐Johnson's index to measure trophic niche breadth using occurrence frequencies is proposed, in order to make it more sensitive to different resource use patterns. The new index ranges from 0 to 1 and measures niche breadth in a guild context. Copyright © 1991, Wiley Blackwell. All rights reserved
