The specific bibliometric dataset utilized to derive the citation-based metrics for this ranking was collected on January 12, 2026. A critical metric that determines a scientist’s position in the ranking is the D-index (Discipline H-index), which uniquely focuses on publications and citation counts strictly within the examined discipline—in this case, Ecology and Evolution—thereby ensuring discipline-specific relevance and precision in ranking outcomes.
Scope of Research and Qualification Criteria
In establishing the ranking, an extensive examination was conducted of 279,971 scientist profiles aggregated from a broad array of bibliometric sources spanning multiple disciplines. Within the domain of Ecology and Evolution, specifically, 17,321 scientists were identified and considered for inclusion.
To qualify for the ranking, a scientist was required to have a D-index of at least 30, with a majority of their tier publications assigned explicitly to Ecology and Evolution. Beyond bibliometric thresholds, researchers’ awards and other notable achievements in the field were incorporated as qualitative factors to complement the quantitative metrics.
The threshold for the D-index was calibrated in increments of 10 relative to the estimated total number of scholars within each discipline, which ensures robust representation of the top 1% of leading experts. Additionally, to maintain alignment between general research output and discipline focus, it was mandated that the proximity between a scientist’s overall H-index and their D-index remain at 30% or less.
Additional Verification and Methodological Integrity
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly impact, all scientist profiles underwent rigorous manual verification. This process involved meticulous cross-correlation of publication records against a wide spectrum of trustworthy academic sources to affirm profile accuracy and the legitimacy of research contributions.
While not directly factored into the positioning within the Research.com ranking, the volume of papers published in prestigious journals and reputable conference proceedings is considered a valuable secondary signal reflecting a scientist’s influence and contribution within their specific field.
Ultimately, each researcher’s position is determined by their D-index derived from data consolidated principally from OpenAlex and CrossRef, reinforcing the ranking’s foundation on the most prominent and well-established bibliometric databases in existence.
