Data Sources and Citation Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in India Ranking is primarily based on extensive bibliometric data collected from leading and reputable sources, including OpenAlex and CrossRef, alongside multiple supplementary databases. The citation metrics and related bibliometric data used for constructing this ranking were compiled on January 12, 2026. To establish a scientist's position within the ranking, we rely on the researcher’s D-index (Discipline H-index), a refined metric that considers only the papers and citation records specific to the Ecology and Evolution discipline, thereby providing a more precise and discipline-focused measure of scientific impact.
Scope of Research and Inclusion Criteria
The ranking process entailed a comprehensive examination of 279,971 scientist profiles sourced from an array of bibliometric databases spanning all scientific disciplines. From this broad cohort, 22 researchers specializing in Ecology and Evolution were specifically evaluated for inclusion.
To qualify for the ranking, a scientist’s D-index had to meet a minimum threshold of 30, and the majority of their tier publications needed to be directly linked to the field of Ecology and Evolution. Additionally, scientists' awards and professional achievements within this discipline were taken into account. The threshold for D-index was dynamically set in increments of 10 relative to the estimated total number of active scholars in each discipline. This approach ensures that the ranking consistently includes the top 1% of leading experts in Ecology and Evolution.
Furthermore, to maintain disciplinary relevance and specialization, a required proximity of 30% or less between a scientist’s general H-index and their discipline-specific D-index was enforced, underscoring the importance of focused research contributions.
Verification Practices and Methodological Rigor
Understanding the inherent limitations of raw bibliometric data as an absolute evaluative tool, the Research.com team implemented a rigorous manual verification process. Each scientist’s profile was carefully reviewed and cross-verified against publications indexed in a broad spectrum of trustworthy academic sources. While the number of publications in prominent journals and conference proceedings does not directly influence the ranking position, such metrics serve as valuable secondary signals of a researcher’s scholarly contributions within Ecology and Evolution.
The ranking position itself is derived using the D-index metric, calculated exclusively from data aggregated through OpenAlex and CrossRef—two of the most comprehensive and respected bibliometric databases accessible to the global research community.
