Data Sources and Ranking Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Brazil Ranking is primarily built upon comprehensive bibliometric data collected from OpenAlex and CrossRef, supplemented by multiple other authoritative data sources. The citation-based metrics used to devise this ranking were gathered on January 12, 2026, ensuring that the evaluation is based on the most current and accurate information available. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively considers papers and citation counts relevant to the specific discipline under examination—in this case, Ecology and Evolution. This approach ensures a focused and discipline-specific evaluation of research impact.
Scope of Research and Qualification Criteria
In compiling the ranking, a total of 279,971 scientist profiles were scrutinized across all disciplines based on data aggregated from diverse bibliometric sources. Among these, 163 scientists specializing in Ecology and Evolution were specifically identified and evaluated. To qualify for inclusion in the ranking, a scientist’s D-index had to meet a minimum threshold of 30, ensuring that only researchers with a significant impact within the field are considered. Additionally, the majority of a qualifying scientist’s tier publications needed to be within Ecology and Evolution. Awards and recognized achievements in the discipline were also factored into the evaluation process to further validate the prominence of each researcher.
The D-index threshold is strategically set at increments of 10, calibrated according to the total estimated number of scholars in each discipline. This methodology guarantees incorporation of the top 1% of leading scholars, balancing inclusivity with selectivity. Moreover, to ensure a harmonized representation of disciplinary focus, a proximity criterion was implemented whereby the difference between a scientist’s general H-index and their D-index should not exceed 30%.
Verification and Validation Practices
The research team behind this ranking acknowledges that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. Hence, all scientist profiles were subjected to meticulous manual verification and cross-correlation against publications from a wide range of trustworthy academic outlets and repositories. While the number of publications in high-impact journals and conference proceedings does not directly influence the ranking position, it provides an important secondary signal of a researcher’s contribution and influence within Ecology and Evolution.
The ranking positions are ultimately established based on the D-index, derived from data obtained primarily through OpenAlex and CrossRef—two of the most prominent and widely recognized bibliometric databases available to the global research community.
