Data Sources and Citation Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Greece Ranking is underpinned by comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple other respected bibliometric repositories. These databases collectively provide an extensive and reliable foundation for analyzing publication and citation metrics. The bibliometric data utilized to devise the citation-based metrics were collected on January 12, 2026, ensuring that the ranking reflects the most current scholarly output available at the time of compilation.
A researcher’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only papers and citations within the specific discipline of Ecology and Evolution. This approach enhances the relevance and accuracy of the ranking by focusing exclusively on a researcher's impact within their specialized field.
Scope of Research and Selection Criteria
The ranking examines a total of 279,971 scientist profiles drawn from a diverse array of bibliometric sources covering all academic disciplines. Within this extensive pool, 29 scientists specializing in Ecology and Evolution were identified and evaluated in depth. To qualify for inclusion in the ranking, a scientist must have achieved a minimum D-index of 30 and have the majority of their high-impact publications situated explicitly in the field of Ecology and Evolution.
In addition to bibliometric thresholds, awards and notable achievements in Ecology and Evolution were also considered to ensure a holistic assessment of a scientist’s contributions. The D-index threshold used to determine top researchers is dynamically set in increments of 10 relative to the estimated total number of scholars in each discipline. This methodology guarantees that the ranking captures approximately the top 1% of leading experts. Furthermore, to maintain fidelity to disciplinary expertise, the proximity between a scientist’s general H-index and their D-index is kept at 30% or less.
Verification Practices and Ranking Methodology
The team behind this ranking is acutely aware that raw bibliometric data alone cannot fully encapsulate the scientific output and influence of scholars. Consequently, all scientist profiles were manually verified and cross-referenced against publication records from a broad range of reputable sources. These additional verification steps strengthen the reliability and credibility of the ranking.
While not directly influencing the ranking positions, the number of published papers in prestigious journals and conference proceedings serves as a valuable secondary signal of a scientist’s impact within Ecology and Evolution.
The ranking positions themselves are determined using each researcher’s D-index, as derived from data gathered via OpenAlex and CrossRef—two of the most authoritative and widely recognized bibliometric databases accessible to the research community.
