Comparing the efficiencies of individual-scoring and complementarity-based algorithms in prioritizing existing protected areas

Evaluation of conservation priorities in existing protected areas (PAs) is critical for effective allocation of limited conservation resources and optimization of PA structure. Traditional approaches of prioritizing within existing PAs are based on individual-scoring and complementarity-based algori...
