Sources of Data and Ranking Basis
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Philippines Ranking is grounded on comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple other authoritative data repositories. The bibliometric data used to develop the citation-based metrics underlying this ranking were collected as of January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric that reflects scholarly impact exclusively within the specific discipline of Ecology and Evolution, thereby ensuring a focused and relevant evaluation of research contributions.
Scope of Research and Qualification Criteria
For this edition, an extensive dataset comprising 279,971 scientist profiles spanning all academic disciplines was rigorously examined, with a targeted subset of 1,467 scientists specifically identified in the field of Ecology and Evolution. To qualify for inclusion in the ranking, a scientist’s D-index must be at least 30, and a majority of their tier publications must be situated within Ecology and Evolution. Further consideration was given to scientists’ awards and notable achievements within the discipline to enhance the robustness of the ranking. The D-index threshold for identifying top researchers is dynamically set in increments of 10, calibrated according to the estimated total number of scholars within each discipline, ensuring representation of the top 1% of leading experts. Additionally, a proximity constraint mandates that the gap between a scientist’s overall H-index and their D-index remain at 30% or less, reinforcing consistency between general and discipline-specific impact.
Additional Verification Practices
The Research.com team acknowledges that raw bibliometric data alone are insufficient to fully capture the nuanced value of a scholar’s output. Therefore, all scientist profiles were meticulously cross-verified through manual review and corroboration against publications indexed in a broad spectrum of reputable sources. While the ranking position is exclusively based on the D-index calculated from OpenAlex and CrossRef data—two of the most respected and widely-used bibliometric databases—secondary indicators such as the number of publications in prominent journals and conference proceedings were recognized as valuable supplemental signals of a researcher’s contribution to Ecology and Evolution.
