A scientist's position within the ranking is determined by their D-index (Discipline H-index). This metric exclusively considers publications and corresponding citations within the examined discipline—in this case, Ecology and Evolution—thereby offering a refined measure of a researcher’s impact specific to their field.
Scope of Research and Eligibility Criteria
The ranking process examined 279,971 scientist profiles aggregated from diverse bibliometric data sources across all scientific disciplines. Within the domain of Ecology and Evolution, 810 scientists were specifically reviewed. To qualify for inclusion in the ranking, a scientist’s D-index was required to be at least 30, ensuring that only researchers with significant scholarly influence are considered.
Furthermore, a qualifying researcher must have had the majority of their tier publications within Ecology and Evolution, underscoring their dedication and expertise in the field. Awards and significant achievements related to Ecology and Evolution were also factored into the vetting process.
The threshold for the D-index is calibrated in increments of 10, adjusted according to the estimated total number of scholars within each discipline. This methodology guarantees that the top 1% of leading scholars are consistently included. Additionally, the difference between a scientist’s general H-index and their D-index must not exceed 30%, ensuring alignment between overall scholarly influence and discipline-specific impact.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, Research.com implements rigorous verification procedures. Each scientist profile is manually reviewed and cross-correlated with publications verified across a variety of trustworthy and authoritative sources.
While the number of papers published in prominent journals and conference proceedings is not a direct factor influencing ranking position, such metrics offer valuable secondary insights into a scientist’s overall contribution to their discipline. The D-index, derived from data collected from OpenAlex and CrossRef—which are among the most prominent and highly regarded bibliometric databases available—remains the primary basis for ranking placement.
