A scientist's position within the ranking is determined by their D-index (Discipline H-index), a discipline-specific variant of the traditional H-index. Unlike a general H-index, the D-index isolates and accounts exclusively for papers and corresponding citations pertinent to the Ecology and Evolution discipline, thereby providing a more accurate reflection of a researcher’s impact within this specialized field.
Scope of Research and Qualification Criteria
The ranking process entailed the examination of 279,971 scientist profiles aggregated from a variety of bibliometric data sources across all scientific disciplines. Among these, 1,111 scientists specialized in Ecology and Evolution were identified and analyzed in detail for this edition.
To qualify for inclusion in the ranking, candidates were required to have a D-index of at least 30, representing a significant threshold for academic influence within the discipline. Furthermore, a majority of the candidate’s tier publications needed to be specifically within Ecology and Evolution to ensure precise disciplinary relevance. Awards and recognitions specific to Ecology and Evolution were also considered as qualitative factors contributing to the overall assessment.
The D-index threshold for consideration adjusts in increments of 10 based on the estimated total number of scholars in each discipline, a methodology designed to consistently incorporate the top 1% of leading experts. Additionally, a proximity criterion was applied such that the difference between a scientist’s general H-index and their Ecology and Evolution D-index does not exceed 30%, ensuring focused disciplinary engagement.
Verification Practices
The Research.com team recognizes that raw bibliometric data alone cannot serve as an absolute tool for evaluating scholarly output. Therefore, all scientist profiles were manually verified and cross-correlated against publications and records in a broad spectrum of trusted sources to validate accuracy and authenticity.
While the ranking position is solely derived from the D-index calculated through bibliometric information from OpenAlex and CrossRef—the leading and most comprehensive databases available—the number of publications in high-impact journals and prominent conference proceedings serves as an important secondary indicator of a scientist’s contribution within Ecology and Evolution.
