A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a specialized metric that accounts solely for papers and citation counts relevant to the discipline under review, in this case, Ecology and Evolution. This approach ensures that the ranking reflects a researcher’s influence specifically within their primary field of study, rather than general citation impact.
Scope of Research and Inclusion Criteria
The ranking encompasses an extensive evaluation of 279,971 scientist profiles identified across a broad spectrum of bibliometric data sources covering all scientific disciplines. From this pool, 57 scientists specializing in Ecology and Evolution were rigorously assessed for inclusion in the ranking.
To qualify for the ranking, a researcher was required to have a minimum D-index of 30, with a majority of their tier publications being situated within Ecology and Evolution. This threshold is carefully calibrated, with increments of 10 applied based on the total estimated number of active scholars per discipline. This methodology maintains a consistent representation of approximately the top 1% of leading researchers, guaranteeing the prominence of the highest-impact scientists.
Additional qualifying criteria ensured that there was a maximum proximity of 30% or less between a scientist’s general H-index and their discipline-specific D-index, thereby confirming focused excellence rather than diffuse scholarly impact. Furthermore, recognition of awards and notable achievements in Ecology and Evolution served as auxiliary factors for validation within the ranking process.
Verification Practices and Data Integrity
Recognizing the limitations of raw bibliometric data as an absolute evaluative tool, the ranking process incorporated rigorous manual verification of all scientist profiles. This involved cross-referencing publications across a wide range of authoritative and trustworthy sources to confirm the accuracy of associated records and to avoid misattribution.
While factors such as the number of articles published in prominent journals and presented at leading conferences do not directly influence a researcher’s placement in the Research.com ranking, they serve as valuable secondary indicators of a scientist’s active and influential contributions to their field.
The position of each researcher is firmly rooted in their D-index, derived from data compiled and validated through OpenAlex and CrossRef — two of the most prominent, widely trusted bibliometric databases available to the global research community.
