A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that isolates and evaluates publications and citations strictly within the examined discipline. This targeted approach allows for an accurate and discipline-specific representation of each researcher’s scholarly impact.
Scope of Research and Qualification Criteria
The scope of this ranking encompasses an initial dataset of 279,971 scientist profiles drawn from a broad range of bibliometric sources, covering all academic disciplines. Specifically, within Ecology and Evolution, 3,000 scientists were examined closely to construct the ranking.
To qualify for inclusion, a researcher must have a D-index of at least 30, and a majority of their top-tier publications must fall within the Ecology and Evolution discipline. Additionally, awards and recognized achievements pertinent to Ecology and Evolution were taken into consideration as qualitative factors enhancing the robustness of the evaluation.
The D-index threshold is calibrated incrementally by tens according to the overall number of scholars identified within each discipline. This adaptive threshold guarantees that the ranking consistently represents the top 1% of leading experts. Furthermore, to ensure that the scientist’s disciplinary impact aligns closely with their general scholarly influence, a proximity rule is applied: the difference between a researcher’s general H-index and their D-index should not exceed 30%.
Verification and Secondary Validation
Recognizing that raw bibliometric data alone cannot fully encapsulate a scholar’s contributions, the Research.com team undertook a thorough manual verification process. Each profile was cross-checked against publications indexed in a wide array of reputable sources to confirm accuracy and relevance.
While the number of publications in prominent journals and conference proceedings does not directly influence the ranking position, it serves as a valuable secondary signal reflecting a scientist’s contributions to their field. The primary ranking metric—the D-index—is consistently derived from data aggregated by OpenAlex and CrossRef, which stand as the most prominent and widely respected bibliometric databases accessible to the research community.
