Institutional position in this ranking is determined by the aggregated D-indexes (Discipline H-index) of all ranking scholars affiliated with an institution, provided their primary publication area falls within Ecology and Evolution. The D-index is calculated solely from publications and citation data pertinent to the examined discipline, ensuring focused and discipline-specific assessment.
Scope of Research
Our evaluation encompassed 279,971 scientist profiles identified from a wide spectrum of bibliometric databases, out of which 28,170 scientists specializing in Ecology and Evolution were closely analyzed. To be considered for the ranking, each scientist needed to meet a qualifying D-index threshold of 30, with the majority of their high-tier publications rooted in the field of Ecology and Evolution. Additionally, scientists’ awards and achievements in Ecology and Evolution were acknowledged as influential factors.
The minimum D-index threshold for top researchers increases in increments of 10, proportionally to the estimated total number of scholars in each discipline, ensuring that the most elite 1% of leading researchers are recognized. A further measure of selectivity is maintained by ensuring the proximity between a scientist’s general H-index and their D-index within 30%, reinforcing the focus on discipline-specific contribution. Awards and achievements within the field added another quality assurance layer to the evaluation process.
Verification and Validation Practices
We recognize that bibliometric datasets, while powerful, are not absolute measures of scholarly impact. Thus, each scientist profile included in our ranking has undergone thorough manual verification and cross-referencing against publications in various highly reliable sources. Although the volume of publications in leading journals and conference proceedings is not a direct factor in our ranking algorithm, it remains an important secondary indicator of research significance and scholarly contribution in any scientific field.
Each researcher's ranking position is determined using their H-index, in alignment with data gathered predominantly from OpenAlex and CrossRef—two of the most prominent bibliometric databases available to the scholarly community.
