A scientist's position within the ranking is determined by their D-index (Discipline H-index), a metric that refines the traditional H-index by considering only publications and citation data pertinent to the examined discipline—in this case, Ecology and Evolution. This discipline-specific approach ensures that the ranking reflects the researcher’s specialized impact rather than their overall scholarly output.
Scope of Research and Eligibility Criteria
The scope of the ranking encompasses an extensive examination of 279,971 scientist profiles identified from a diverse array of bibliometric data sources spanning all scientific disciplines. Within Ecology and Evolution specifically, 1,213 scientists were evaluated. Inclusion in the ranking requires that a scientist’s D-index must be at least 30, emphasizing a significant and sustained contribution to the discipline. Additionally, a majority of the researcher’s tier publications must be focused within Ecology and Evolution to ensure domain relevance. Awards and achievements pertinent to Ecology and Evolution also factor into the evaluation process.
The threshold for the D-index is established incrementally by 10 points relative to the estimated total number of scholars in each discipline. This rigorous calibration guarantees representation of the top 1% of leading experts in their respective fields. Furthermore, to maintain consistency and discipline-specific evaluation, the proximity between a scientist’s general H-index and their D-index must be ≤30%, confirming that their disciplinary impact is aligned with their overall scholarly productivity.
Verification and Quality Assurance
Recognizing that raw bibliometric data alone cannot fully capture the nuanced contributions of researchers, the team behind this ranking undertook meticulous manual verification of all scientist profiles to enhance validity and reliability. Each profile was cross-correlated against a broad spectrum of authoritative publication sources to confirm affiliation, publication records, and domain specificity.
While the number of publications in prestigious journals and conference proceedings does not directly influence a scientist’s ranking position, it serves as a valuable complementary indicator of their scholarly prominence within Ecology and Evolution.
Ultimately, the ranking positions are assigned strictly based on each researcher’s D-index, derived from data sourced from OpenAlex and CrossRef. These platforms represent the most credible and comprehensive bibliometric databases currently available to the scientific community.
