A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that encompasses only those papers and citation counts directly associated with the examined discipline—in this case, Ecology and Evolution. This approach ensures that the ranking reflects discipline-specific research impact, rather than general scholarly influence.
Scope and Criteria of the Ranking
The ranking methodology considered an extensive dataset comprising 279,971 scientist profiles drawn from a variety of bibliometric sources across all scientific disciplines. Within this broad cohort, 68 scientists specializing in Ecology and Evolution were specifically examined for the purpose of this ranking.
To qualify, each scientist’s D-index had to meet a minimum threshold of 30, and the majority of their tier publications were required to be in the field of Ecology and Evolution. Additional factors, such as awards and notable achievements within the discipline, were also incorporated to contextualize the quantitative metrics.
The threshold for the D-index varies by discipline, typically set in increments of 10 reflective of the estimated size of the scholarly community in each field. This adaptive threshold guarantees inclusion of the top 1% of leading experts while maintaining rigor. Moreover, a proximity criterion was enforced wherein the difference between a scientist’s general H-index and their D-index must be no greater than 30%, ensuring alignment between general research impact and discipline-specific contributions.
Verification and Validation Practices
The Research.com team recognizes the inherent limitations of raw bibliometric data as a sole measure of scholarly output. Accordingly, all scientist profiles were thoroughly and manually verified by cross-referencing publications against a wide array of trustworthy academic sources. This meticulous validation process significantly enhances the reliability and integrity of the ranking.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s placement in the ranking, it constitutes a valuable secondary indicator of scientific contribution within a given field. The rank itself is established solely on the researcher’s D-index as precisely derived from OpenAlex and CrossRef—the most respected and widely used bibliometric databases accessible to the research community at large.
