A scientist's position within the ranking is determined by their D-index (Discipline H-index), a refined metric that evaluates scholarly impact exclusively within the examined discipline. This approach isolates publications and citation metrics strictly relevant to Ecology and Evolution, thereby providing a discipline-specific measure of research influence and productivity.
Scope and Criteria of the Ranking
The ranking was developed after examining a total of 279,971 scientist profiles aggregated from diverse bibliometric data sources, spanning all scientific disciplines. Within this extensive dataset, a focused subset of 90 scientists specializing specifically in Ecology and Evolution were identified for inclusion in the ranking.
To be considered eligible for this ranking, researchers were required to have a D-index of at least 30, and the majority of their tier publications needed to fall within the field of Ecology and Evolution. In addition to bibliometric measures, scientists’ awards and documented achievements in Ecology and Evolution were factored into the evaluation process, ensuring that recognized excellence beyond citation counts was also acknowledged.
The threshold D-index for consideration is calibrated as increments of 10, tailored to the specific estimated population size of scholars in each discipline. This methodology guarantees that the ranking consistently incorporates the top 1% of leading scientists in Ecology and Evolution. Moreover, to ensure discipline specificity, only researchers exhibiting a proximity of 30% or less difference between their general H-index and their Discipline H-index were included, thereby confirming a concentrated scholarly focus in the field.
Verification and Validation Practices
The creators of this ranking are acutely aware that bibliometric data, in its raw form, is never intended to be an absolute measure of a scholar’s overall academic output or impact. Accordingly, every scientist profile included in the ranking underwent rigorous manual verification and was cross-correlated against publications listed in a broad array of trustworthy academic sources.
While not directly influencing the ranking position, the quantity of papers published in prominent journals and conference proceedings also serves as a valuable secondary indicator of a scientist’s contribution to Ecology and Evolution research. This additional contextual information supports the comprehensive evaluation of each researcher’s academic footprint.
Ultimately, the ranking position is firmly anchored on each researcher’s D-index as derived from data aggregated from OpenAlex and CrossRef. These platforms are recognized for their extensive coverage and data quality in the bibliometric domain.
