Abstract:
Seed dispersal is one of the essential aspects of plant life cycles that promote the recolonization of degraded sites and naturally restored lands. Bibliometrics has become a necessary tool for analyzing and assessing the output of scientists, cooperation between universities and other related parameters. This review covered the studies carried out between 2001 and 2024. It aims to identify the frequency methods used and dispersal agents and analyze publication trends by utilizing network analysis, identifying leading countries, and visualizing keyword co-occurrence patterns. The results found that seed traps and animal faeces collection are frequently used, while animal dispersal (zoochory) is the most intensive seed dispersal agent studied. However, the findings reveal that scholars from 51 countries were actively engaged in seed dispersal research based on study site and 83 based on institutional affiliations, with the USA leading in both options. Additionally, the analysis revealed that genetic structure and biological control, such as DNA, are emerging fi elds in seed dispersal studies. The study recommends that future seed dispersal research emphasize explosive, gravity, and water dispersal mechanisms with limited agents and larger coverage.
