A researcher's position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that only accounts for publications and citations within the specific discipline under examination—in this case, Ecology and Evolution. This approach allows for a targeted and accurate reflection of a scientist’s impact within their field rather than relying on more generalized metrics.
Scope of Research and Inclusion Criteria
The ranking process initially examined a total of 279,971 scientist profiles across all research disciplines using diverse bibliometric data sources. From these, 171 scientists specializing in Ecology and Evolution were identified for further consideration. To qualify for inclusion, a scientist must have attained a D-index of at least 30, with a majority of their tier publications being directly attributable to Ecology and Evolution.
In addition to bibliometric performance, a scientist’s awards and professional achievements in Ecology and Evolution were also carefully evaluated to contribute to the qualification process. The threshold for the D-index is dynamically set as an increment of 10, calibrated according to the estimated total number of active researchers within each discipline. This design ensures that the ranking consistently incorporates the top 1% of scholars in their respective fields.
Moreover, there is a requirement that the proximity between a scientist’s general H-index and their D-index should be no more than 30%. This criterion safeguards that researchers included in the ranking demonstrate a focused and substantial impact within Ecology and Evolution specifically, rather than an indiscriminate distribution of scholarly influence.
Verification and Ranking Methodology
Recognizing the limitations of raw bibliometric data— which is never sufficient as a standalone tool to fully evaluate scholarly output—the team behind this ranking implemented extensive manual verification of all scientist profiles. This verification process involved cross-correlation with publications indexed in a broad array of trustworthy sources to ensure accuracy and authenticity of the information presented.
While not directly influencing the ranking positions, the number of papers published in high-impact journals and leading conference proceedings is considered a valuable secondary indicator of a scientist’s contribution to their field. The final ranking positions are established exclusively using each researcher’s D-index based on data curated from OpenAlex and CrossRef, two of the most authoritative and widely recognized bibliometric databases accessible to the research community.
