The bibliometric data used to formulate the citation metrics were collected on January 12, 2026, ensuring the inclusion of the most current and relevant research outputs. Each scientist’s position in the ranking is determined by their D-index (Discipline H-index), a metric that reflects the collective impact of a researcher’s publications and citations strictly within the examined discipline of Ecology and Evolution. The D-index thus serves as a focused measure of disciplinary research excellence, excluding publications and citations outside this scope.
Scope of Research and Qualification Criteria
An extensive evaluation was conducted on a dataset comprising 279,971 scientist profiles identified across a wide spectrum of disciplines through multiple bibliometric sources. Specifically, within Ecology and Evolution, 1,000 scientists were examined to ensure robust disciplinary representation.
To qualify for inclusion in the ranking, a scientist must have achieved a minimum D-index of 30, signifying substantive impact in Ecology and Evolution. Additionally, the majority of their tier publications—those contributing to their D-index—must be situated within the Ecology and Evolution domain. Consideration was also given to notable awards and achievements in this specialized field, further refining the assessment of scholarly prominence.
The threshold for the D-index is calibrated as increments of 10, adjusted relative to the total estimated number of researchers within each discipline. This calibration ensures the inclusion of the top 1% of leading scholars while maintaining rigorous standards tailored to each academic community. Furthermore, eligibility requires that the difference between a scientist’s overall H-index and D-index not exceed 30%, reinforcing the disciplinary specificity of the metric and ranking.
Verification and Validation Practices
Understanding the limitations of raw bibliometric data as an absolute evaluation tool, the Research.com team undertook meticulous manual verification processes. Each scientist profile was cross-checked against a broad range of trusted sources and publication repositories to confirm accuracy and relevance of recorded outputs in Ecology and Evolution.
While not a direct factor influencing ranking positions, the volume of publications in prominent journals and conference proceedings is acknowledged as a valuable secondary indicator of a researcher’s contribution within their specialization. This supplementary insight highlights the breadth and visibility of scholarly work beyond citation counts alone.
Positions in the ranking are established using each researcher's D-index derived from data from OpenAlex and CrossRef, which are currently the most prominent and extensively curated bibliometric databases accessible to the research community.
