A scientist’s position within this ranking is determined by their D-index (Discipline H-index), which is a specialized variation of the traditional H-index. The D-index exclusively accounts for publications and citations within the examined discipline of Ecology and Evolution, providing a focused measurement of impact specific to this field.
Scope of Research and Ranking Eligibility
For this edition, 279,971 scientist profiles were examined across all disciplines using a broad array of bibliometric data sources. Among these, 382 researchers specializing in Ecology and Evolution were identified and evaluated in detail. To qualify for inclusion in the ranking, a scientist needed to meet two primary criteria:
- A minimum D-index of 30, ensuring inclusion of scholars with substantial disciplinary impact.
- The majority of their tier publications had to be explicitly situated within Ecology and Evolution research.
Additionally, awards and other recognized achievements in Ecology and Evolution were considered to further validate the prominence of each researcher within the field.
The D-index threshold is calibrated in increments of 10 depending on the estimated total number of scholars for each discipline. This approach ensures that the top 1% of leading experts globally are incorporated into the ranking. Moreover, a proximity filter mandates that the difference between a scientist’s overall H-index and their D-index remains approximately 30% or less to confirm disciplinary focus and relevance.
Verification and Methodological Rigor
Understanding that raw bibliometric data alone is never sufficient to fairly and fully evaluate a scholar’s output, the Research.com team carried out extensive manual verification of all scientist profiles. Profiles were cross-correlated against publications indexed in a wide range of reputable sources to confirm accuracy and comprehensiveness.
While the number of publications in leading scientific journals and conference proceedings does not directly influence a researcher’s position in the ranking, it remains a valuable secondary indicator of scholarly contribution and research quality within Ecology and Evolution.
The ranking position is ultimately determined by the carefully computed D-index, based on data extracted from OpenAlex and CrossRef — the preeminent bibliometric databases in the research ecosystem.
