Data Sources and Methodology
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Madagascar Ranking is primarily based on bibliometric data aggregated from leading open scientific databases, including OpenAlex and CrossRef, alongside multiple other reputable data sources. The citation-based metrics used to devise this ranking were extracted and processed on January 12, 2026. Central to the ranking methodology is the D-index (Discipline H-index), a refined metric that considers only a researcher’s publication and citation records within the specific discipline under examination, Ecology and Evolution in this case. This approach ensures that the ranking accurately reflects a scientist’s impact and influence tailored to the discipline.
Scope of Research and Ranking Criteria
The scope of the ranking involved examination of 279,971 scientist profiles across all disciplines compiled from heterogeneous bibliometric data repositories. Within the domain of Ecology and Evolution specifically, 1,xxxx scientists were screened for inclusion. To qualify for the ranking, a scientist must have a D-index of at least 30, and the majority of their tier publications needed to be focused on Ecology and Evolution. In addition, consideration was given to scientists’ awards and notable achievements within the field, further enhancing the reliability of the ranking as a reflection of true disciplinary excellence.
The D-index threshold for recognizing top researchers is set dynamically as increments of 10 relative to the estimated total number of scholars per discipline, with a key objective to incorporate the top 1% of leading experts. Furthermore, eligibility requires a close alignment—within 30% difference—between a scientist’s overall H-index and their D-index, ensuring consistent disciplinary focus rather than broad or divergent citation profiles.
Verification Processes and Additional Considerations
Understanding that raw bibliometric data cannot solely capture the full breadth of a scholar’s research impact, the Research.com team undertook extensive manual verification of all scientist profiles. These profiles were cross-validated against publications from a broad spectrum of trustworthy sources to eliminate inconsistencies and errors. While the core ranking metric remains the D-index derived from OpenAlex and CrossRef data—acknowledged as the most prominent and authoritative bibliometric databases available—the number of publications in prestigious journals and leading conference proceedings was also reviewed as a valuable secondary indicator of research contributions in Ecology and Evolution.
It is important to note that publication quantity in high-impact venues does not directly influence rank position but serves as a supplementary signal affirming a researcher’s standing in the community.
