Niche-based mechanisms mediating the impacts and mitigation of biological invasion
Sebastian Ruile·Mikael Pontarp
• We develop a trait- and niche-based theoretical model to analyse invasion dynamics. • Generalist invaders profit from their strong competitiveness, while specialists profit from empty niche spaces. • Ecological specialisation and niche position strongly mediate invasion impact. • Optimal level of removal effort differs among diversity indices, emphasising that control programs should align their effort levels with clearly defined biodiversity objectives. • Results provide mechanistic insight t
