Bibliometric data used to generate citation-based metrics were collected on January 12, 2026. Importantly, the ranking is constructed around a researcher's D-index (Discipline H-index), a refined metric that considers only those publications and citation counts relevant to the specific discipline under review. This approach enables precise evaluation of a scientist’s impact strictly within Ecology and Evolution, rather than their overall scientific output.
Scope of Research and Inclusion Criteria
The ranking methodology was applied to a comprehensive dataset comprising 279,971 scientist profiles identified across diverse bibliometric sources spanning all scientific disciplines. Within this extensive pool, 1,142 scientists specializing in Ecology and Evolution were specifically examined.
To qualify for inclusion in the ranking, a scientist was required to have a D-index of at least 30. Beyond the numerical threshold, a majority of their high-impact publications needed to be within the Ecology and Evolution domain to ensure disciplinary relevance. Additionally, recognition such as awards and achievements within the field played a role in confirming a researcher’s prominence.
The D-index threshold is dynamically set as increments of 10, contingent upon the estimated total number of scholars within each discipline. This stratagem guarantees that at least the top 1% of leading experts are incorporated into the ranking. Furthermore, a proximity criterion was applied whereby the difference between a scientist’s general H-index and their Discipline-specific D-index must be 30% or less, ensuring consistency between their overall and discipline-specific research impact metrics.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot fully capture scholarly contributions, the Research.com team conducted meticulous manual verification of all scientist profiles included in the ranking. This labor-intensive process involved cross-correlating profile data against publications indexed in a wide variety of reputable sources to safeguard against inaccuracies and misattributions.
While this ranking does not explicitly use publication counts in prestigious journals and conference proceedings as a factor determining position, such quantitative data represent a valuable secondary indicator of a researcher’s influence within Ecology and Evolution. This supplementary signal provides additional context for understanding scientific contributions beyond citation metrics.
The definitive ranking position for each scientist is established based on their D-index, computed using comprehensive information derived from OpenAlex and CrossRef—two of the most authoritative bibliometric databases available to the research community today.
