Diversity in interaction strength promotes rich dynamical behaviours in a three-species ecological system
作者：
Highlights：
• The effects of asymmetrical interactions on community dynamics are examined.
• Transcritical, Hopf and Gavrilov–Guckenheimer bifurcations emerge in this system.
• These bifurcations lead to distinct outcomes e.g. coexistence, oscillatory dynamics.
• Asymmetrical interactions can promote the maintenance of biodiversity.
• The emergence of limit cycles leads to destabilisation of multi-species communities.
