A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that only considers publications and citations within the examined discipline of Ecology and Evolution. This approach ensures that rankings reflect discipline-specific research impact rather than cross-disciplinary publication volume or citations.
Scope of Research and Eligibility Criteria
The ranking comprehensively examined a total of 279,971 scientist profiles derived from various bibliometric repositories across all scientific disciplines. From this broad pool, 105 scientists specializing specifically in Ecology and Evolution were identified for inclusion.
To qualify for the ranking, a scientist must meet two principal criteria:
- A minimum D-index of 30 within Ecology and Evolution, ensuring that only researchers with significant disciplinary impact are considered.
- The majority of their tiered publications (i.e., high-impact outputs) must be primarily in the field of Ecology and Evolution.
In addition to citation metrics, scientists’ notable awards and achievements within Ecology and Evolution were evaluated as supporting evidence of their standing.
The D-index threshold for considering top researchers is strategically set in increments of 10 based on the estimated total number of scholars per discipline. This graduated threshold ensures that the ranking consistently encapsulates the top 1% of leading scholars while maintaining rigorous standards. Furthermore, a proximity criterion requires that the difference between a scientist’s general H-index and their Ecology and Evolution-specific D-index does not exceed 30%, reinforcing the relevance of their disciplinary impact.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot fully capture the multifaceted contributions of scholars, Research.com employs rigorous manual verification processes. Each scientist’s profile was carefully cross-correlated against publications indexed in additional trusted academic sources to ensure accuracy and authenticity.
While the number of papers published in prestigious journals and reputable conference proceedings was not a direct factor influencing the ranking position, it remains a valuable secondary indicator of a researcher’s influence and contribution within Ecology and Evolution.
Ultimately, the ranking positions are established based on the D-index calculated from data sourced primarily from OpenAlex and CrossRef. These databases are the most prominent and reliable open bibliometric resources available to the global research community, further enhancing the credibility and transparency of the ranking methodology.
