The ranking methodology centers on each researcher’s D-index (Discipline H-index), a refined metric that considers only those papers and citations pertinent to the specific discipline under review. This approach allows for a precise assessment of a scientist’s impact and productivity within the defined field of Ecology and Evolution, rather than relying on generalized bibliometric indicators.
Scope of Research
To establish a robust and authoritative ranking, a total of 279,971 scientist profiles identified across a broad array of bibliometric data sources were initially examined, encompassing all scientific disciplines. From this extensive pool, 424 scientists specializing specifically in Ecology and Evolution were further analyzed.
In order to qualify for inclusion in the ranking, a researcher’s D-index was required to be at least 30. Additionally, a majority of their tier publications had to be substantially within the domain of Ecology and Evolution to ensure disciplinary relevance. Where applicable, scientists’ awards and other notable achievements in Ecology and Evolution were also taken into consideration, adding further depth and nuance to the evaluation.
The D-index threshold for recognizing top researchers was dynamically set in increments of 10, relative to the total estimated number of scholars within the discipline. This strategy guarantees that the top 1% of leading scientists in Ecology and Evolution are incorporated into the ranking. Moreover, a proximity criterion was applied, stipulating that the difference between a scientist’s overall H-index and their discipline-specific D-index be no more than 30%, thus ensuring that their impact within Ecology and Evolution remains representative of their broader academic influence.
Additional Verification Practices
We recognize the inherent limitations of raw bibliometric data as a sole evaluative tool in assessing the full scope of scholarly output. Therefore, each scientist’s profile underwent a rigorous manual verification process. This included cross-correlation of publication records against a wide range of established and trustworthy academic sources to validate authorship, disciplinary focus, and research authenticity.
While not a direct factor influencing the ranking position, the volume of publications in prominent, peer-reviewed journals and conference proceedings was evaluated as a valuable secondary indicator of a researcher’s substantive contribution to their field. This secondary assessment enriches the context within which the ranking is interpreted.
The final ranking positions are determined using the researchers’ D-index values extracted exclusively from OpenAlex and CrossRef, which are widely recognized as the premier bibliometric databases available to the scientific community today.
