A scientist’s position within the ranking is determined by their D-index (Discipline H-index). Unlike a general H-index, the D-index is discipline-specific and considers only papers and citation metrics relevant to the examined field—in this case, Ecology and Evolution. This focused approach allows for a precise evaluation of a researcher’s impact within their specialized domain.
Scope of Research and Qualification Criteria
The ranking process encompassed a thorough examination of 279,971 scientist profiles identified across diverse bibliometric sources spanning all academic disciplines. Within the Ecology and Evolution discipline specifically, 68 scientists met the key criteria to be considered.
To qualify for inclusion in the ranking, a scientist’s D-index needed to be at least 30. Additionally, a majority of their tier publications were required to be clearly classified within Ecology and Evolution. Beyond bibliometric thresholds, notable awards and achievements within the field were also taken into account, ensuring recognition of both quantitative and qualitative measures of scholarly excellence.
The D-index threshold is dynamically calibrated as an increment of 10 based on the estimated total number of scholars within each discipline. This approach guarantees that the top 1% of leading experts are incorporated into the list. Furthermore, to maintain the integrity of discipline-specific expertise, the discrepancy between a scientist’s general H-index and their D-index was limited to no more than 30%, ensuring those ranked demonstrate a consistent focus in Ecology and Evolution.
Verification and Validation Practices
Recognizing that raw bibliometric data alone do not capture the full spectrum of scholarly contribution, the Research.com team implemented rigorous manual verification protocols. Each scientist profile was meticulously cross-referenced against publications indexed in trustworthy databases and additional credible sources.
Although the number of publications in leading journals and conference proceedings does not directly influence the ranking position, it serves as a valuable secondary indicator of scientific contribution and prominence within the field.
The final ranking positions are established using the D-index calculated from data aggregated by OpenAlex and CrossRef, two of the most prominent and rigorously curated bibliometric databases accessible to the global research community.
