Ecological networks quantify the structure of biotic interactions, providing a framework to evaluate their spatial dynamics under global change. While climate and human influence are important predictors of network structure, we hypothesize that such effects depend on the interaction type and the organisms involved. It remains unknown whether different types of ecological networks such as mutualistic (plant-pollinator, seed-dispersal) and antagonistic (host–parasite) respond similarly to anthropogenic pressures and climate. Addressing this gap is critical to understand how ecological communities are reshaped under global change. We aim to test whether mutualistic and antagonistic networks exhibit consistent or divergent structural responses to human impact and climatic conditions.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Location</h3>\u0000 \u0000 <p>Global.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Time Period</h3>\u0000 \u0000 <p>1967–2020.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Major Taxa Studied</h3>\u0000 \u0000 <p>Animalia, Plantae.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We compiled 383 mutualistic and antagonistic ecological networks worldwide and characterized their structure with connectance, nestedness, modularity and specialization metrics.

Bird-mediated networks were highly sensitive to human impacts, exhibiting increased nestedness in seed-dispersal networks and decreased modularity and specialization in plant-pollinator networks.
