Bibliometric data to construct the citation-based metrics utilized in this ranking were meticulously collected as of January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric that specifically includes only those papers and citation counts pertinent to the discipline under examination — in this case, Ecology and Evolution. This discipline-focused approach ensures that the ranking accurately reflects a researcher’s impact within their specialized field rather than more generalized citation measures.
Scope of Research and Qualification Criteria
This ranking analyzed an extensive pool of 279,971 scientist profiles identified across diverse bibliometric data sources spanning all disciplines. Of these, 3,000 scientists associated specifically with Ecology and Evolution were examined in depth.
To qualify for inclusion in the ranking, a researcher’s D-index had to meet a minimum threshold of 30, with the majority of their tier publications demonstrably situated within the Ecology and Evolution domain. Additionally, the evaluation took into account notable awards and achievements specifically relevant to this field. The D-index threshold is carefully calibrated in increments of 10, adjusted based on the estimated total number of scholars in each discipline, while guaranteeing representation of the top 1% of leading experts in the ranking.
Another critical qualification criterion is the proximity between a scientist’s overall H-index and their D-index, which must not exceed a 30% difference. This measure helps ensure that the ranking reflects researchers whose general scholarly influence aligns closely with their impact in Ecology and Evolution.
Verification Practices
The researchers behind this ranking acknowledge that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. In recognition of this, all scientist profiles have undergone manual verification and extensive cross-correlation with publications listed in a broad array of trustworthy, authoritative sources. This rigorous verification underscores our commitment to accuracy and credibility.
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 contribution to their specific research area.
It is important to reiterate that the ranking position is ultimately established by applying each researcher’s D-index according to bibliometric information derived from OpenAlex and CrossRef.
