At the core of the ranking methodology is the D-index (Discipline H-index), a citation metric that exclusively aggregates papers and citations within the specific academic discipline of Ecology and Evolution. This targeted approach ensures that a scientist’s standing accurately reflects their impact and productivity in their primary field of research.
Scope of Research Examined
To frame the context of this ranking, a total of 279,971 scientist profiles drawn from multiple bibliometric data sources were evaluated across all scientific disciplines. Focusing specifically on Ecology and Evolution, 139 scientists were identified and assessed according to established inclusion criteria.
In order to qualify for ranking consideration, researchers were required to have a D-index of at least 30, with the majority of their tier publications—those recognized for their scientific prominence—originating within the Ecology and Evolution disciplines. Additional factors such as awards and professional achievements within the field were incorporated to further validate the researchers’ contributions.
The threshold for the D-index was carefully calibrated in increments of 10, adjusted according to the estimated total number of scholars active in each discipline. This calibration ensures that the top 1% of leading scholars are consistently represented while maintaining a proximity margin of 30% or less between a scientist’s general H-index and their discipline-specific D-index, thereby reinforcing the ranking’s discipline-centered focus.
Additional Verification Practices
Recognizing the limitations of raw bibliometric data as absolute evaluative tools, our team undertook meticulous manual verification of all scientist profiles included in the ranking. This involved cross-correlation of publication records across a broad spectrum of authoritative and trustworthy sources to confirm accuracy and authenticity.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it serves as a valuable secondary indicator of their scholarly contributions to Ecology and Evolution.
The final rankings are established using each researcher’s D-index, predominantly computed from data aggregated from OpenAlex and CrossRef. We encourage readers interested in the detailed methodology and validation processes underpinning these rankings to visit our methodology page.
