A key metric driving the ranking is the D-index (Discipline H-index), which is a refined h-index considering only papers and citations strictly within the examined discipline of Ecology and Evolution. This approach provides a focused measure of a researcher’s influence specific to their field, avoiding dilution from unrelated disciplines.
Scope of Research and Eligibility Criteria
The ranking process started with an extensive examination of 279,971 scientist profiles amassed from several established bibliometric data sources, spanning all scientific disciplines. From this vast pool, 310 scientists specializing in Ecology and Evolution were identified and subjected to further analysis.
To qualify for inclusion in this ranking, a scientist had to meet the following criteria:
- Possess a D-index of at least 30, ensuring a significant level of scholarly impact within Ecology and Evolution.
- Have a majority of their tier publications—those considered most influential and impactful—within the specific area of Ecology and Evolution.
- Earn recognition through awards and notable achievements specifically tied to Ecology and Evolution, which served as supplementary validation.
The D-index threshold is dynamically adjusted by increments of 10, depending on the estimated total number of scholars in each discipline. This method guarantees that the top 1% of leading researchers are incorporated into the list, maintaining exclusivity and rigor. Additionally, the difference between a scientist’s overall H-index and their discipline-specific D-index must not exceed 30%, ensuring alignment between general and specialized impact metrics.
Verification and Validation Practices
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly productivity and impact, the Research.com team applied meticulous manual verification procedures. Each scientist’s profile was carefully cross-correlated against publications and academic records from a wide array of trustworthy and authoritative sources.
While the number of publications in prominent journals and conference proceedings does not directly affect a researcher’s position in the ranking, these outputs serve as valuable secondary indicators of contribution and influence within the Ecology and Evolution community.
The final ranking positions were established using the verified D-index values derived from OpenAlex and CrossRef, which are widely acclaimed as the most comprehensive and accessible bibliometric databases available to the global research community.
