Data from: Meta-analysis shows overall benefits of cattle silvopastoral systems for biodiversity in fragmented forest landscapes

This submission contains three interrelated datasets supporting a
systematic review and meta-analysis of biodiversity responses to
cattle-based silvopastoral systems (SPS) in fragmented forest landscapes
(Perez-Alvarez et al., Ecological Applications, 2026). The study
synthesizes evidence from 45 studies across 15 countries, four
biogeographic regions, and seven taxonomic groups to evaluate how SPS
affect biodiversity (species diversity and abundance) relative to treeless
pastures and natural forests. The datasets are organized to reflect the
sequential workflow of the meta-analysis: from literature screening and
study selection, through effect-size calculation, to sensitivity analyses.
They are linked by a common study_id identifier that allows records to be
traced across files.
