Data Sources and Citation Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Fiji Ranking is grounded in a comprehensive aggregation of bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other reputable databases. These platforms represent some of the most authoritative and widely recognized repositories for scholarly metadata. The bibliometric data used to calculate the citation-based metrics for the ranking were collected as of January 12, 2026. A researcher’s position in this ranking is determined by their Discipline H-index, or D-index, a metric that uniquely evaluates citation impact based exclusively on publications and citations within the Ecology and Evolution discipline.
Scope of Research and Ranking Criteria
A total of 279,971 scientist profiles were examined across all academic disciplines using bibliometric data from diverse and credible sources. Specifically, the Ecology and Evolution discipline included 1,000 scientists who met rigorous inclusion criteria. To qualify for this ranking, a scientist’s D-index needed to be at least 30, and a majority of their tier publications were required to fall within the Ecology and Evolution domain. In addition, recognition of a scientist’s awards and achievements within this field was incorporated as a supplementary factor in the evaluation.
The threshold for the D-index used to identify leading researchers is adjusted in increments of 10, aligned to the estimated size of the scholarly population within each discipline. This approach ensures the inclusion of the top 1% of scholars while maintaining a balanced representation across fields. Furthermore, to validate the disciplinary focus, only scientists whose general H-index and D-index differ by 30% or less were considered, ensuring that the ranking reflects true domain expertise rather than generalized citation impact.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot comprehensively evaluate scholarly output, the Research.com team undertook extensive manual verification processes. Each scientist’s profile was meticulously cross-referenced against publications indexed in a wide array of trusted academic sources to validate the accuracy and relevance of the data. Although the number of publications in high-impact journals and conference proceedings does not directly influence the ranking position, these metrics serve as an important secondary signal of a scientist’s contribution within Ecology and Evolution.
The ranking is thus established through the D-index gathered primarily from OpenAlex and CrossRef — the two most prominent and reliable bibliometric databases accessible to the academic community.
