A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively considers papers and citation counts within the specified discipline—Ecology and Evolution in this case—providing a more accurate reflection of their impact and productivity specific to the field.
Scope and Criteria of the Ranking
To construct the ranking, a comprehensive examination was undertaken of 279,971 scientist profiles drawn from diverse bibliometric sources across all scientific disciplines. Within the specific area of Ecology and Evolution, 139 scientists were identified for detailed evaluation. To qualify for inclusion in the ranking, researchers were required to have a D-index of at least 30. Furthermore, a majority of their tier publications needed to be focused on Ecology and Evolution, ensuring the relevance of their research contributions to the field.
In addition to bibliometric criteria, evaluation of scientists’ awards and achievements within Ecology and Evolution was incorporated to complement an assessment of scholarly impact. The D-index threshold is dynamically set in increments of 10, proportional to the estimated total number of scholars in each discipline, while guaranteeing that the top 1% of leading scholars are represented in the list. Additionally, only scientists whose D-index is within approximately 30% or less of their overall general H-index were considered. This constraint ensures alignment between their discipline-specific and general research influence.
Verification and Validation Procedures
The researchers responsible for this ranking are keenly aware that raw bibliometric data alone cannot serve as an absolute measure to evaluate scholarly output. To address this limitation, all scientist profiles were manually verified and cross-correlated against publications from a broad array of trustworthy and authoritative sources. This meticulous review process enhances the reliability and credibility of the ranking.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it constitutes a valuable secondary indicator of meaningful contributions to Ecology and Evolution.
The ranking positions are ultimately established using the D-index calculated from the carefully aggregated datasets of OpenAlex and CrossRef. These platforms remain the backbone of the bibliometric analysis as the foremost and most respected data sources in the research domain.
