Data Sources and Citation Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Norway Ranking is derived from a robust and diverse set of bibliometric data sources. The primary data sources include OpenAlex and CrossRef, which are complemented by multiple other reputable bibliometric databases. On January 12, 2026, comprehensive bibliometric data were collected to devise the citation-based metrics underpinning this ranking. A researcher’s position is determined by their Discipline H-index (D-index), a specialized metric that accounts exclusively for papers and citation counts within the examined discipline of Ecology and Evolution, ensuring a focused evaluation of impact within the relevant field.
Scope and Selection Criteria
The ranking process involved the examination of 279,971 scientist profiles spanning all disciplines, with a targeted analysis of 145 scientists specifically identified within Ecology and Evolution. To qualify for inclusion in this ranking, a researcher’s D-index had to be at least 30, and the majority of their tier publications needed to be substantively related to Ecology and Evolution. Beyond bibliometric metrics, scientists’ awards and notable achievements in the field were also taken into account to ensure recognition of quality and leadership.
The D-index threshold is adaptively set in increments of 10, corresponding to the estimated total number of active scholars per discipline. This adaptive thresholding guarantees that the top 1% of leading researchers within Ecology and Evolution are consistently incorporated into the list. Additionally, a proximity of 30% or less between a scientist’s general H-index and their discipline-specific D-index is required to confirm a scientist’s focused impact in the field rather than broader interdisciplinary work.
Additional Verification Practices
The team behind the ranking acknowledges that raw bibliometric data alone do not capture the full scope or nuance of a researcher’s scholarly contributions. Consequently, all scientist profiles underwent meticulous manual verification and were cross-correlated with publications indexed in a wide range of trustworthy academic sources. While the quantity of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it serves as a valuable secondary signal supporting the assessment of a researcher’s contribution to Ecology and Evolution.
Position in the ranking is ultimately established through each researcher’s D-index, informed by comprehensive information collected from OpenAlex and CrossRef—two of the most prominent and widely recognized bibliometric databases accessible to the research community.
