Isotopic niche is not equal to trophic niche
Ecol Lett.
2019 Nov.
Abstract
The work of Sheppard et al. (Ecol. Lett., 21, 2018, 1395) relies on the strong assumption that isotopic niche is equal to trophic niche. Here I raise three main concerns showing that classic hypotheses built upon trophic niche cannot be directly interpreted in isotopic space. Future studies should always keep isotopic and trophic niches distinct.
Keywords: Feeding strategy; intragroup competition; isotopic space; niche overlap; niche partitioning; stable isotope; trophic space.
