In this scope, consistent patterns of outstanding biodiversity have been identified in agroforestry systems within diverse biogeographic regions and types of management. Empirical work has revealed that agroforestry higher structural complexity, when compared with current simplified agricultural systems, might be partially responsible for the observed patterns. The recently developed Habitat Amount Hypothesis predicts diversity for a local habitat patch, from the amount of the same habitat within the local landscape. We have expanded the previous hypothesis to the landscape level, computing the influence of the dominant land uses on the diversity of coexisting guilds. As a case study, we have considered archetypal landscapes dominated (or co-dominated) by crops or trees, which were compared using normalized diversities. The results obtained show that agroforestry systems substantially increase functional diversity and overall biodiversity within landscapes. We highlight that the normalized values should be parametrized to real conditions where the type of crop, tree and agroecological management will make a difference. Most importantly, our findings provide additional evidence that agroforestry has a critical role in enhancing biodiversity in agricultural landscapes and, in this way, should be regarded as a priority measure in European Agri-environmental funding schemes PB Frontiers SN 2296-701X YR 2022 FD 2022-01-27 LK https://hdl.handle.net/10347/44267 UL https://hdl.handle.net/10347/44267 LA eng NO Santos M, Cajaiba RL, Bastos R, Gonzalez D, Petrescu Bakı ¸s A-L, Ferreira D, Leote P, Barreto da Silva W, Cabral JA, Gonçalves B and Mosquera-Losada MR (2022) Why Do Agroforestry Systems Enhance Biodiversity?
