A scientist's position within the ranking is established according to their D-index (Discipline H-index), a refined metric that exclusively considers papers and citations relevant to the Ecology and Evolution discipline. This approach provides a focused evaluation of scholarly impact within this specific research area, avoiding bias introduced by unrelated fields.
Scope of Research and Qualification Criteria
The ranking process began with the examination of 279,971 scientist profiles extracted from a wide variety of bibliometric sources, spanning all scientific disciplines. Among these profiles, 6,000 scientists specifically associated with Ecology and Evolution were identified and evaluated.
To qualify for inclusion in this ranking, a scientist was required to meet the following criteria:
- A minimum D-index of 30, reflecting substantive research output and citation impact in Ecology and Evolution.
- A majority of their tier publications had to be directly attributable to the Ecology and Evolution discipline, ensuring alignment with the ranking’s focus area.
- Recognition of awards and achievements specific to Ecology and Evolution was also taken into account as a factor supporting the candidate's standing.
The threshold for the D-index is calibrated in increments of 10, based on the estimated total number of researchers within each discipline. This strategy guarantees inclusion of the top 1% of leading scholars per discipline. Furthermore, a maximum proximity of 30% between a researcher’s overall H-index and their D-index was maintained to confirm the relevance of their impact within Ecology and Evolution.
Additional Verification Practices
The Research.com team fully acknowledges that raw bibliometric data alone should not be used as an absolute measure of scientific output or quality. Accordingly, every scientist profile included in the ranking underwent a rigorous manual verification process. This involved cross-correlating authorship and publication information against a broad array of trustworthy sources to validate the authenticity and disciplinary relevance of each researcher’s work.
While the number of publications in prominent journals and conference proceedings is not a direct factor determining a scientist’s position, it is recognized as a valuable secondary indicator of research contribution and visibility in the field.
Overall, ranking positions are assigned based on each researcher’s D-index, derived from verified data sourced from OpenAlex and CrossRef—the most prominent and well-regarded bibliometric databases accessible to the global research community.
