A central metric guiding the ranking positions is the D-index (Discipline H-index), which exclusively accounts for papers and citation metrics within the examined discipline of Ecology and Evolution. This focused approach ensures that the ranking reflects a researcher’s impact and productivity specifically within their specialized area of study, rather than their overall scientific output.
Scope of Research and Inclusion Criteria
To comprehensively map the leading researchers in Ecology and Evolution, a total of 279,971 scientist profiles were initially examined across a broad spectrum of disciplines. Narrowing this scope, 57 scientists specialized in Ecology and Evolution were identified for detailed evaluation.
To qualify for inclusion in the ranking, a scientist was required to meet the following criteria:
- A minimum D-index of 30.
- A majority of their tier publications must be firmly situated in the field of Ecology and Evolution.
- Recognition of awards and notable achievements within Ecology and Evolution was also incorporated as an evaluative factor.
The D-index threshold applied to identify top researchers is dynamically set in increments of 10. This calibration depends on the total number of scholars estimated for each discipline and is designed to ensure inclusion of the top 1% of leading experts in the ranking. Furthermore, to maintain focus on discipline-specific impact, a proximity of 30% or less between a scientist’s general H-index and their D-index is required, reinforcing the emphasis on specialized scholarly contributions.
Verification and Validation Practices
Understanding the inherent limitations of raw bibliometric data, the Research.com team has adopted rigorous manual verification procedures to enhance the credibility and accuracy of the ranking. Each scientist profile included was manually cross-checked against a wide array of trusted publication sources to confirm the precision of author details and disciplinary scope.
While the number of papers published in prominent journals and conference proceedings does not directly affect a researcher’s ranking position, it serves as an important secondary signal of the researcher’s contribution to their field. This additional perspective helps contextualize the D-index and overall scholarly impact.
The final ranking position is established solely based on each researcher’s D-index, calculated from data gathered through OpenAlex and CrossRef, underscoring the methodological rigor behind this initiative.
