A scientist’s ranking position is determined by their D-index (Discipline H-index), a refined bibliometric indicator that considers only those publications and citations relevant to the examined discipline. This approach ensures discipline-specific accuracy by evaluating researchers based solely on their contributions within Ecology and Evolution.
Scope of Research and Qualification Criteria
The analytical scope of this ranking encompasses a broad examination of 279,971 scientist profiles derived from a variety of bibliometric data sources across all disciplines globally, with a focused subset of 1,000 scientists identified specifically within Ecology and Evolution. To qualify for inclusion, a researcher’s D-index must be at least 30, and the majority of their tier publications must be situated firmly within the Ecology and Evolution domain.
In addition to bibliometric performance, scientists’ awards and achievements within the specific field of Ecology and Evolution were carefully considered to augment the rigor and relevance of the ranking. The D-index threshold for recognizing top scholars is systematically adjusted in increments of 10 based on the estimated total population of researchers in each discipline, guaranteeing the inclusion of the top 1% of leading experts.
Furthermore, for meaningful representation, care was taken to ensure that there is a proximity of 30% or less between a scientist's general H-index and their D-index, reinforcing that the ranking reflects specialized impact rather than generalized research performance.
Additional Verification Practices
Understanding the limitations of raw bibliometric data as an absolute evaluative tool, the Research.com team employed meticulous manual verification for each scientist profile. This process involved cross-referencing publication records against a wide array of trustworthy sources to confirm authenticity and relevance.
While not directly influencing ranking positions, the number of publications in prominent journals and conference proceedings was also reviewed as a valuable secondary indicator of a researcher’s contribution to Ecology and Evolution.
The final ranking positions are established using each researcher's verified D-index as calculated from OpenAlex and CrossRef data—esteemed and widely recognized bibliometric databases within the global research community.
