A scientist's position in the ranking is determined by their D-index (Discipline H-index), a specialized metric that strictly accounts for papers and citation counts relevant to the examined discipline—in this case, Ecology and Evolution—thereby providing a field-specific measure of research impact and influence.
Scope of Research and Qualification Criteria
The ranking analysis began with an extensive examination of 279,971 scientist profiles identified through a variety of bibliometric data sources spanning all scientific disciplines. Specifically, for the discipline of Ecology and Evolution, 1,000 scientists were identified and reviewed for inclusion in the ranking.
To qualify for the ranking, a scientist's D-index had to be at least 30, with the majority of their tier publications firmly focused within the domain of Ecology and Evolution. Additionally, awards and notable achievements in the field were factored into our qualitative assessment.
The D-index threshold is dynamically set as increments of 10, calibrated to the estimated total number of scholars in each discipline, ensuring that the ranking incorporates the top 1% of leading researchers. To maintain disciplinary relevance, we require a proximity of 30% or less between a scientist’s overall general H-index and their discipline-specific D-index.
Verification and Validation Process
We recognize that bibliometric data alone cannot fully capture the nuanced contributions of researchers. Therefore, all scientist profiles included in the ranking underwent a rigorous manual verification process. This included cross-correlating their bibliometric data and publication records with a wide spectrum of trustworthy and independent sources, ensuring the accuracy and authenticity of the information presented.
While the number of papers published in prominent journals and conference proceedings does not directly affect a researcher’s ranking position, it serves as a valuable secondary indicator of their scientific contribution and influence within Ecology and Evolution.
Ultimately, the ranking position is established using the D-index metric, derived from data aggregated principally from OpenAlex and CrossRef—two of the most prominent and reliable bibliometric databases widely acknowledged by the global research community.
