Data Sources and Methodology Overview
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Saudi Arabia Ranking is founded on comprehensive bibliometric data predominantly sourced from OpenAlex and CrossRef, supplemented by multiple other reputable data repositories. The citation-based metrics utilized for establishing the ranking were compiled on January 12, 2026. Central to the ranking methodology is the D-index (Discipline H-index), a refined bibliometric indicator that measures a researcher’s impact exclusively within the examined discipline by including only relevant papers and their citation metrics. This discipline-specific metric ensures that the ranking reflects domain-focused scholarly influence rather than general research output.
Scope of Research and Ranking Criteria
The ranking process considered an extensive pool of 279,971 scientist profiles aggregated from various bibliometric sources encompassing all scientific disciplines. From this large dataset, 6 scientists specializing in Ecology and Evolution in Saudi Arabia were specifically evaluated. To qualify for the ranking, a scientist was required to have a D-index of at least 30, ensuring a high level of scholarly contribution within Ecology and Evolution. Moreover, a majority of the scientist’s tier publications needed to be concentrated in this field, further reinforcing domain relevance.
Additional qualitative considerations included the assessment of awards and achievements pertinent to Ecology and Evolution, providing an enriched context for evaluating each candidate’s standing. The threshold D-index for top researchers is dynamically set as increments of 10, tailored according to the estimated number of scholars in each discipline. This approach guarantees inclusion of the top 1% echelon of scholars per field. Furthermore, to affirm the disciplinary focus of the ranking, the difference between a scientist’s overall H-index and their D-index was required to be within 30%, ensuring alignment between their general academic stature and domain-specific excellence.
Verification and Validation Procedures
The research team behind this ranking recognizes that raw bibliometric data, while indispensable, cannot solely capture the nuanced impact of scholarly output. Accordingly, all scientist profiles were manually verified and cross-referenced against a broad spectrum of trustworthy sources to confirm the accuracy and integrity of the data. Although not directly influencing a researcher’s rank, the number of publications in prominent journals and conference proceedings was regarded as a valuable secondary indicator of scientific contribution within the field.
By integrating verified D-index data from OpenAlex and CrossRef—two of the most respected and widely used bibliometric databases accessible to the global research community—this ranking aspires to maintain rigorous standards of credibility and precision.
