Species interactions, environmental gradients and body size shape population niche width
Eloranta, Antti; Finstad, Anders Gravbrøt; Sandlund, Odd Terje; Knudsen, Rune; Kuparinen, Anna; Amundsen, Per-Arne (Peer reviewed; Journal article, 2021)1. Competition for shared resources is commonly assumed to restrict population-level niche width of coexisting species. However, the identity and abundance of coexisting species, the prevailing environmental conditions, ... -
