A key metric used to determine each scientist’s position in the ranking is the D-index (Discipline H-index). The D-index selectively accounts only for publications and citation data within the specific discipline under examination, in this case, Ecology and Evolution. This discipline-specific focus allows the ranking to reflect researchers’ impact and productivity precisely within their core area of study.
Scope of Research and Ranking Criteria
For this edition, we examined 279,971 scientist profiles aggregated from a broad array of bibliometric datasets across all scientific disciplines. Specifically, 1,000 researchers identified as active contributors in Ecology and Evolution were closely evaluated. To qualify for inclusion in this ranking, a scientist must have a D-index of at least 30, with the majority of their tier publications pertaining to Ecology and Evolution.
In addition to bibliometric thresholds, scientists’ awards and recognized achievements within Ecology and Evolution were incorporated as evaluative factors to enrich the contextual validity of the ranking. The threshold for the D-index is dynamically adjusted in increments of 10 relative to the estimated total number of scholars within the discipline, ensuring that the ranking reliably includes the top 1% of leading researchers.
Furthermore, to maintain a consistent disciplinary focus, we require that the difference between a scientist’s overall general H-index and their D-index must not exceed 30%, ensuring close alignment between their discipline-specific impact and broader research performance.
Additional Verification and Quality Assurance
Recognizing that raw bibliometric data alone cannot provide an absolute evaluation of scholarly output, the Research.com team undertakes rigorous manual verification of all profiles included in this ranking. Each scientist’s publication record was cross-checked against multiple trustworthy sources to affirm authenticity and disciplinary relevance.
Although metrics such as the number of publications in prominent journals and conference proceedings do not directly influence the positioning in the ranking, they serve as valuable secondary indicators of a scientist’s contribution and prominence within Ecology and Evolution.
The ranking positions are ultimately established using the validated D-index values derived from OpenAlex and CrossRef data—currently the most prominent and widely recognized bibliometric databases accessible to the research community.
