Inconsistent effects of P enrichment and predator presence on food‐web dynamics in a bromeliad system

Oikos, Volume 2026, Issue 3, March 2026.
Food webs consist of trophic interactions of variable strength. However, it remains challenging to predict how changes in environmental conditions, such as nutrient enrichment, can affect these interactions. In this paper, we propose to integrate food web theory with ecological stoichiometry, which predicts how elemental ratios affect trophic ...
