Data Sources Utilized for the Ranking
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Lebanon Ranking is primarily based on comprehensive bibliometric data drawn from established and reliable databases, including OpenAlex and CrossRef, augmented by multiple other trusted data sources. The bibliometric information used for calculating the citation-based metrics essential to this ranking was collected on January 12, 2026. Central to determining a scientist’s position in the ranking is the application of the D-index (Discipline H-index), a metric that exclusively considers papers and citation counts pertinent to the examined discipline, thereby providing a refined and discipline-specific measure of scholarly impact.
Scope of Research and Inclusion Criteria
A total of 279,971 scientist profiles, identified through a synthesis of diverse bibliometric data sources spanning all disciplines, were assessed for this edition. From these, 2 scientists specializing in Ecology and Evolution were specifically examined. To qualify for inclusion in the ranking, researchers were required to have a D-index of at least 30, with a majority of their tier publications situated within the Ecology and Evolution field. In addition to bibliometric indicators, scientists’ noteworthy awards and formal achievements within Ecology and Evolution were also considered as important factors.
The threshold for the D-index was set incrementally by tens, scaling according to the total estimated population of scholars in each discipline. This approach ensures that the ranking reflects the top 1% of leading scholars accurately. An additional qualifying criterion required the D-index to be within 30% or less of the scientist’s general H-index, safeguarding that specialists featured in this ranking maintain a significant focus on Ecology and Evolution relative to their overall research output.
Verification Procedures and Methodological Rigor
Recognizing that raw bibliometric data alone cannot serve as an absolute tool for evaluating scholarly contributions, the Research.com team implemented rigorous manual verification processes. Each scientist profile was carefully cross-checked against a broad range of reputable publication sources to validate accuracy and authenticity. While the number of papers published in prestigious journals and conference proceedings does not directly influence the ranking position, it serves as a valuable secondary signal reflecting a scientist’s substantive contribution to their research area.
The final ranking positions are anchored in the D-index metrics ascertained through data from OpenAlex and CrossRef—two of the most prominent and internationally respected bibliometric databases accessible to the research community.
