Data Sources and Ranking Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Norway Ranking is founded on a comprehensive and diverse set of bibliometric data, primarily sourced from OpenAlex and CrossRef, alongside multiple other reputable databases. The acquisition of citation-based metrics utilized in the ranking occurred on January 12, 2026. Each scientist’s standing in the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that isolates publication and citation data strictly related to their discipline of Ecology and Evolution. This approach ensures that the evaluation is focused and relevant to the specific research domain.
Scope of Research and Inclusion Criteria
A total of 279,971 scientist profiles spanning a wide array of disciplines were examined through an extensive bibliometric database review. Within this dataset, 145 scientists specializing in Ecology and Evolution were identified and considered for the ranking. To qualify, candidates were required to have a minimum D-index of 30 and demonstrably contribute the majority of their tier publications within Ecology and Evolution. Additionally, scientists’ awards and professional achievements in the field were factored into the assessment.
The threshold for the D-index is calibrated incrementally by tens relative to the estimated number of scholars in each discipline, allowing the ranking to consistently include the top 1% of leading experts. A proximity limit of 30% or less between a scientist's overall H-index and their discipline-specific D-index was also enforced to ensure alignment and disciplinary focus.
Verification and Validation Practices
Recognizing the complexities and limitations inherent in raw bibliometric data, the Research.com team implements an exhaustive manual verification process. All scientist profiles were meticulously cross-checked against publications confirmed in a broad spectrum of trustworthy academic sources. While not directly influencing ranking positions, the volume of publications in prestigious journals and conference proceedings serves as a valuable secondary indicator of a researcher’s impact within Ecology and Evolution.
The primary positioning in the ranking is derived from the D-index computed with data exclusively from OpenAlex and CrossRef, acknowledged as two of the most authoritative bibliometric databases accessible to the scientific community.
