Dynamic nutrient competition (de-)stabilizes photosymbiosis

ABSTRACT Photosymbioses between heterotrophic hosts and phototrophic symbionts are critical to productivity in oligotrophic aquatic ecosystems. The ecological success of this relationship is rooted in the efficient metabolic exchange between symbiotic partners, yet this nutrition...

Complexity promotes stability in mutualistic networks through weaker mutualistic dependencies: Insights from Generalized Modelling

Abstract Mutualistic networks provide essential contributions to long‐term ecosystem functioning and food security, but Anthropocene stressors continue to alter their structure and size. Previous theoretical approaches produce conflicting predictions for how network features infl...
