Bibliometric data used to calculate the citation-based metrics underlying this ranking were harvested on 2026-01-12, ensuring a recent and relevant dataset. A scientist’s position in the ranking is determined exclusively by their Discipline H-index (D-index), a refined variant of the conventional H-index that specifically evaluates a researcher’s output and citations attributable only to their examined discipline, in this case Ecology and Evolution.
Scope of Research and Inclusion Criteria
The ranking evaluates a substantial cohort extracted from a total of 279,971 scientist profiles identified across all disciplines using diverse bibliometric data sources. From this broad pool, 29 scientists specializing in Ecology and Evolution were carefully identified for inclusion.
To qualify for the ranking, a researcher must have achieved a minimum D-index of 30, with a majority of their tier publications being within the Ecology and Evolution discipline. Additionally, scientists’ awards and notable professional achievements within Ecology and Evolution were considered to provide further validation of their scholarly impact and field leadership.
The D-index threshold for identifying top researchers is set in increments of 10, calibrated according to the estimated total number of scholars in each discipline. This adaptive thresholding ensures that the ranking consistently captures the top 1% of leading scholars within the respective field. Furthermore, to confirm disciplinary focus and impact, a researcher’s general H-index and their D-index must be within 30% proximity, guaranteeing alignment between overall productivity and discipline-specific contribution.
Verification and Methodological Rigor
We recognize that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. Accordingly, every researcher profile included in the ranking underwent meticulous manual verification. This process involved cross-correlation of publications against a broad spectrum of authoritative and trustworthy sources to ensure accuracy and to mitigate errors commonly encountered in automated data aggregation.
Though not directly influencing the numerical ranking position, the volume of papers published in prominent journals and reputable conference proceedings was reviewed as a valuable secondary signal, reinforcing the assessment of a scientist’s research contributions in Ecology and Evolution.
The position in the ranking is fundamentally derived using each scientist’s D-index, calculated from data obtained via OpenAlex and CrossRef, recognized as leading bibliometric platforms globally accessible to the research community for their reliability and comprehensive coverage.
