Data Sources and Citation Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Malaysia Ranking is meticulously derived from comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, along with multiple other reputable data repositories. The citation-based metrics that underpin this ranking were collected and aggregated on January 12, 2026. These metrics inform the calculation of each scientist’s D-index (Discipline H-index), a refined bibliometric indicator which exclusively considers publications and citation counts within the examined discipline of Ecology and Evolution. This focus ensures the ranking accurately reflects scholarly impact specific to the field rather than general citation performance.
Scope of Research and Eligibility Criteria
The ranking process evaluated a total of 279,971 scientist profiles identified across a broad array of bibliometric databases and covering all academic disciplines. Within the subfield of Ecology and Evolution specifically, 7 scientists met the rigorous criteria for inclusion. To qualify for the ranking, a scientist must have a D-index of at least 30, which represents a baseline level of sustained scholarly contribution within the discipline. Additionally, a majority of the researcher’s tier publications must be centered in Ecology and Evolution to ensure relevancy.
Alongside bibliometric indicators, scientists’ awards and professional achievements within Ecology and Evolution were also factored into the selection process to better contextualize their scholastic influence. The D-index threshold is dynamically set in increments of 10 relative to the estimated number of scholars in each discipline. This ensures that, regardless of discipline size, the ranking consistently incorporates the top 1% of leading experts. Furthermore, the ranking requires that the proximity between a scientist’s general H-index and their D-index remains within 30%, safeguarding the focus on discipline-specific impact.
Verification and Evaluation Practices
The Research.com team acknowledges that raw bibliometric data alone cannot serve as an absolute measure of research quality or significance. Consequently, all scientist profiles featured in the ranking undergo manual verification and are cross-correlated against publication records from a wide variety of trusted academic sources. This meticulous process enhances the reliability and validity of the ranking outcomes.
While not directly influencing a researcher’s ranking position, the quantity of papers published in prominent journals and conference proceedings is considered a valuable secondary indicator of scientific contribution within the Ecology and Evolution community.
Ultimately, the position of each researcher in this ranking is determined by their D-index, which is calculated from data gathered through OpenAlex and CrossRef—the most comprehensive and respected bibliometric databases accessible to the research community.
