To ensure currency and relevance, the bibliometric data underpinning all citation-based metrics utilized for this ranking were collected on January 12, 2026. A scientist’s rank within the list is determined based on their Discipline H-index (D-index), a refined bibliometric indicator that considers only those publications and citations directly associated with the examined discipline—in this case, Ecology and Evolution. This discipline-specific approach guarantees a more accurate reflection of an individual’s impact within their specialized research area rather than their overall scientific output.
Scope of Research and Inclusion Criteria
This edition systematically examined a total of 279,971 scientist profiles identified from diverse bibliometric data sources spanning all scientific disciplines. Within this extensive dataset, 1,312 scientists specializing in Ecology and Evolution were isolated for focused analysis.
To qualify for inclusion in the ranking, a researcher was required to possess a D-index of at least 30, ensuring a threshold of documented scholarly influence in the field. Furthermore, the majority of tier publications contributing to the D-index needed to be in the domain of Ecology and Evolution, underscoring expertise specificity. Additional qualitative considerations included scientists’ documented awards and achievements recognized within the Ecology and Evolution community.
The D-index eligibility threshold is calibrated as an incremental scale of 10 and adjusted in accordance with the total estimated population of scholars in each discipline. This method ensures the ranking consistently represents approximately the top 1% of leading experts for every specialized field.
Lastly, to confirm disciplinary focus, only candidates exhibiting a proximity of 30% or less between their overall H-index and their discipline-specific D-index were considered. This criterion guarantees that the ranking highlights those researchers whose impact is principally embedded within Ecology and Evolution, rather than outside it.
Verification and Methodological Rigor
The research team behind this ranking remains acutely aware that raw bibliometric data should never be regarded as an absolute or sole metric for evaluating scholarly output. To address this, all scientist profiles were subjected to meticulous manual verification, with their publication records and citations cross-validated against a broad array of trustworthy and authoritative sources.
While the number of papers published in high-impact journals and prestigious conference proceedings is not a direct factor influencing a researcher’s position within the Research.com ranking, it serves as a valuable secondary signal of the scientist’s contribution to their particular field, providing an additional layer of qualitative context.
The finalized ranking positions are established using each researcher’s D-index as calculated through information extracted predominantly from OpenAlex and CrossRef—two of the most reliable and widely utilized bibliometric databases in the academic research community.
