Bibliometric data used to devise the citation-based metrics featured in this ranking were collected on January 12, 2026. The methodology centers around the D-index (Discipline H-index), a refined metric that evaluates a researcher’s scientific impact specifically within the examined discipline. By focusing exclusively on papers and citations pertinent to Ecology and Evolution, the D-index ensures a highly relevant and precise reflection of scholarly influence within the field.
Scope of Research and Ranking Criteria
To create an inclusive yet discipline-specific ranking, a thorough examination was conducted across 279,971 scientist profiles identified from diverse bibliometric sources across all scientific disciplines. Within the domain of Ecology and Evolution, exactly 1,XXX scientist profiles (please update with exact number if known) were analysed in detail.
Eligibility requirements for inclusion in the ranking include a minimum D-index of 30. Additionally, a majority of a scientist’s tier publications must focus on Ecology and Evolution to ensure relevance to the field. Consideration was also given to awards and notable achievements specific to Ecology and Evolution to enhance the qualitative aspect of the assessment.
The D-index threshold for identifying top researchers is systematically set in increments of 10, based on the estimated total number of scholars active in each discipline. This approach guarantees the inclusion of the top 1% of leading scholars in the final listing. Furthermore, to ensure consistency, the proximity between a scientist’s overall H-index and their D-index within the discipline is maintained at 30% or less, reinforcing discipline-specific prominence without excessive divergence.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot fully represent a scholar’s scientific contributions, the Research.com team undertook extensive manual verification of all scientist profiles. This process involved cross-correlating publication records against a broad array of trustworthy sources to validate authorship and disciplinary relevance.
While the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it remains a valuable secondary indicator of a scientist’s research contributions and scholarly stature within Ecology and Evolution.
The final ranking is determined using the D-index derived exclusively from OpenAlex and CrossRef data, the most prominent and widely respected bibliometric databases available to the research community. Researchers and institutional representatives interested in the detailed methodology are encouraged to consult our methodology page for further insights.
