Data Sources and Citation Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Kenya Ranking is primarily derived from comprehensive bibliometric data drawn from OpenAlex and CrossRef, supplemented by multiple other reputable data sources. Bibliometric information used to develop the citation-based metrics was collected on January 12, 2026, ensuring recent and robust data underpin the evaluation process. A scientist's position in the ranking is determined by their D-index (Discipline H-index), which uniquely considers only papers and citation metrics within the targeted discipline of Ecology and Evolution, providing a refined measure of impact specific to this field.
Scope of Research Considered
The ranking was constructed through an extensive review of 279,971 scientist profiles identified across a variety of bibliometric repositories spanning all academic disciplines. From this broad dataset, a focused examination was conducted of 3,027 scientists specializing specifically in Ecology and Evolution. To qualify for inclusion in the ranking, a scientist’s D-index had to meet or exceed 30, and the majority of their tier publications needed to be within Ecology and Evolution. Additionally, scientists’ awards and notable achievements in the field were carefully considered to affirm their eminence. The D-index threshold for top researcher consideration is set in increments of 10 relative to the estimated total number of scholars in each discipline, ensuring the selection of the top 1% of leading experts. Furthermore, a proximity criterion was applied whereby a researcher’s general H-index and their D-index differ by no more than 30%, ensuring alignment between general and discipline-specific impact.
Verification and Validation Procedures
Recognizing that raw bibliometric data alone cannot provide an absolute measure of scholarly contribution, the ranking team employed additional verification practices. All scientist profiles were manually validated and cross-correlated against publications indexed in a wide range of authoritative and trustworthy sources to ensure accuracy and reliability. While the number of papers published in leading journals and conference proceedings does not directly affect the ranking position, it is considered a valuable secondary indicator of a scientist’s contributions to Ecology and Evolution. The primary ranking metric—the D-index—is calculated based on citation and publication data obtained from OpenAlex and CrossRef, which are among the most prominent and widely respected bibliometric databases available to the global research community.
