Data Sources and Citation Metrics
The ranking of the Best Ecology and Evolution Scientists in Sweden, now in its 5th edition, is developed based on comprehensive bibliometric data gathered primarily from OpenAlex and CrossRef, supplemented by multiple additional reputable data sources. The citation-based metrics used to devise this ranking were collected on January 12, 2026, ensuring the data reflects a recent and robust snapshot of scholarly output. Each scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric that specifically focuses on a researcher’s publications and citations within the defined discipline of Ecology and Evolution, thereby providing a refined and discipline-specific measure of scholarly impact.
Scope of Research and Ranking Criteria
The foundation of this ranking involved an extensive examination of 279,971 scientist profiles curated from various bibliometric sources, covering all academic disciplines. Within this comprehensive dataset, 216 scientists specializing in Ecology and Evolution were identified and evaluated in detail. To qualify for inclusion in the ranking, a researcher’s D-index had to meet a minimum threshold of 30, with the majority of their high-impact publications consistently situated within Ecology and Evolution. Additionally, awards and other notable achievements in the field were considered to further validate a scientist’s relevance and excellence.
The threshold for the D-index is calibrated in increments of 10 relative to the total estimated number of scholars in each discipline, ensuring inclusion of the top 1% of leading experts. Furthermore, to guarantee disciplinary focus, the difference between a scientist’s general H-index and their D-index is maintained at 30% or less, ensuring that their impact is predominantly within Ecology and Evolution.
Verification Practices and Methodological Integrity
The researchers responsible for this ranking acknowledge that raw bibliometric data alone cannot comprehensively capture the full scope of a scholar’s contributions. Therefore, all scientist profiles were manually verified and cross-correlated against publications verified from a diverse range of trustworthy academic sources to ensure accuracy and authenticity.
While the D-index remains the central metric determining ranking positions, the number of publications in prominent journals and prestigious conference proceedings is recognized as a valuable secondary indicator of a scientist’s influence within their field, even though it does not directly impact the ranking order.
The comprehensive ranking is based on D-index values calculated using detailed information derived from OpenAlex and CrossRef, two of the most authoritative and widely recognized bibliometric databases accessible to the global research community.
