Biotic resistance hypothesis
WebSep 6, 2024 · Alternatively, the biotic resistance hypothesis predicts that a species-rich community will inhibit invasion (Elton 1958; Kennedy et al. 2002), because complementarities among numerous resident species more fully exploit resources and natural enemies reduce niche opportunity for the invader (Naeem et al. 2000; Shea and … WebThe biotic resistance hypothesis argues that complex plant and animal communities are more resistant to invasion than simpler communities. Conversely, the biotic acceptance hypothesis states that non‐native and native species richness are positively related. Most tests of these hypotheses at continental scales, typically conducted on plants ...
