A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that accounts solely for papers and citation data relevant to the specific discipline under review—in this case, Ecology and Evolution. This approach provides a focused measure of research impact within the examined field, distinguishing it from more general author-level citation indices.
Scope of Research and Eligibility Criteria
This ranking considers a broad scope of research, having examined 279,971 scientist profiles identified from multiple bibliometric databases across all academic disciplines. Among these, only 2,000 scientists with a focus on Ecology and Evolution were specifically analyzed for inclusion in this edition.
To qualify for the ranking, a scientist’s D-index in Ecology and Evolution had to meet or exceed a threshold of 30. Additionally, a substantial majority of their tier publications needed to be concentrated in the Ecology and Evolution domain. Beyond quantitative metrics, a researcher’s awards and professional achievements in the field were also carefully considered to reflect broader scholarly contributions.
The D-index threshold is rigorously calibrated and is incremented by 10 points based on the estimated size of the scholarly population within each discipline, ensuring that the list consistently captures the top 1% of leading experts. To ensure disciplinary relevance, scientists included exhibit a proximity of no more than 30% between their general H-index and their D-index within Ecology and Evolution.
Verification and Validation Procedures
The Research.com team recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly impact. Accordingly, all scientist profiles underwent thorough manual verification and were cross-checked against a wide range of trustworthy sources and publication records. This careful process reduces potential discrepancies and elevates the quality and reliability of the ranking.
While not directly influencing ranking positions, the quantity of papers published in prestigious journals and recognized conference proceedings was recorded as a secondary indicator of a scientist’s contribution within Ecology and Evolution.
The ranking’s methodology, anchored on the D-index calculated from data curated via OpenAlex and CrossRef, showcases a rigorous and transparent approach to academic assessment. Readers interested in more detailed information are encouraged to visit our methodology page.
