Each institution’s position in the ranking is determined by the cumulative D-index (Discipline H-index) of all affiliated scholars whose primary publication record is in Ecology and Evolution. The D-index incorporates only publications and citation data specific to the examined discipline, ensuring a focused and accurate assessment of institutional impact in this field.
Scope of the Ranking and Scientist Selection
The scope of research underlying the ranking is substantial: profiles of 279,971 scientists identified from various bibliometric data sources were reviewed, with a focused analysis of 28,170 scientists specifically from the fields of Ecology and Evolution. To ensure rigor and relevance, the qualifying D-index threshold for each scientist was set at 30, with the additional requirement that the majority of their high-impact publications fall within Ecology and Evolution.
Scientist awards and field-specific achievements were also considered as criteria for inclusion. For the identification of top researchers, the D-index threshold is incremented by units of 10 in alignment with the overall number of active scholars estimated for each discipline—always ensuring that the ranking encompasses at least the top 1% of leading scholars worldwide. Moreover, only scientists whose general H-index is within 30% of their D-index were considered, safeguarding discipline-specific recognition.
Rigorous Verification Practices
At Research.com, we recognize that raw bibliometric data are never an absolute tool for evaluating scholarly impact. Thus, all scientist profiles were manually verified and cross-examined against a wide array of recognized and trustworthy publication sources. Although the count of published papers in leading journals and conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it remains a valuable supplementary signal of individual contribution to the field.
The final ranking is derived from each scientist’s H-index values, as reported by both OpenAlex and CrossRef—the preeminent bibliometric databases leveraged by the global research community. These measures, combined with our stringent verification protocols, ensure the credibility and integrity of the ranking.
