A scientist's position within this ranking is determined by their Discipline H-index, or D-index. This metric exclusively considers publications and citation counts within the specific discipline of Ecology and Evolution, thereby providing a focused measure of research influence in this field.
Scope and Criteria of Research Included
For this edition, an extensive dataset of 279,971 scientist profiles spanning all disciplines was initially examined, including 14 scientists specifically identified within Ecology and Evolution. To qualify for inclusion in the ranking, researchers were required to meet a minimum D-index threshold of 30 and to have the majority of their tier publications situated within Ecology and Evolution.
In addition to bibliometric impact, scientists' awards and notable achievements within Ecology and Evolution were considered as supplementary indicators of excellence. The D-index thresholds are calibrated incrementally by 10 points relative to the total estimated number of scholars per discipline, ensuring that the top 1% of leading experts are comprehensively represented.
Furthermore, to maintain disciplinary specificity, candidates were verified to have no greater than a 30% disparity between their general H-index and their D-index, assuring that their impact is strongly aligned with Ecology and Evolution research.
Additional Verification and Validation Practices
The research team recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly output. Consequently, every scientist profile included in this ranking underwent manual verification and cross-correlation against publications listed in a broad spectrum of trusted sources.
While not directly influencing ranking positions, the quantity of publications in prominent journals and conference proceedings was evaluated as a valuable secondary signal, reflecting a scientist’s broader contribution to the field.
The ranking itself is established based on each researcher’s D-index derived from OpenAlex, CrossRef, and related authoritative platforms—universally acknowledged as the most prominent bibliometric databases accessible to the research community.
