Data Sources and Ranking Methodology
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Jersey Ranking was developed using an array of reputable and comprehensive bibliometric databases. The primary sources include OpenAlex and CrossRef, complemented by multiple additional bibliometric data providers to ensure a thorough and balanced dataset. Bibliometric data, collected on January 12, 2026, served as the foundation for the citation-based metrics employed throughout the ranking process.
A scientist’s position within this ranking is determined exclusively by their D-index (Discipline H-index), which reflects citation metrics and publications strictly within the examined discipline of Ecology and Evolution. This discipline-specific metric enables a focused evaluation of scholars’ impact restricted to their primary area of expertise.
Scope of Research and Eligibility Criteria
The ranking encompasses a comprehensive examination of 279,971 scientist profiles identified from a diverse set of bibliometric data sources spanning all disciplines, with a focused sub-cohort of 1,XXX scientists specifically active in Ecology and Evolution.
To qualify for inclusion, candidates were required to meet a minimum D-index threshold of 30. Moreover, a majority of their tier publications needed to be substantively related to Ecology and Evolution, ensuring relevance and topical specialization. Awards and recognized achievements within the field were also considered as supplementary factors reinforcing a scientist’s standing.
The D-index threshold is dynamically adjusted in increments of 10 depending on the estimated total population of researchers in each discipline. This adaptive mechanism ensures the inclusion of the top 1% of leading scholars in every respective field. Additionally, the methodology mandates a proximity limit of 30% or less between an individual's overall H-index and their D-index, thereby confirming coherence between general academic impact and discipline-specific influence.
Additional Verification Procedures
Recognizing the inherent limitations of raw bibliometric data as an absolute measure of scientific output, our research team implemented rigorous manual verification practices. Each scientist profile was painstakingly cross-correlated with publications indexed across a variety of trusted sources to authenticate accuracy and comprehensiveness.
While the count of publications in prestigious journals and high-impact conference proceedings does not influence ranking placement directly, it serves as an important secondary signal of a researcher’s substantive contribution to their field.
The ranking positions are ultimately adjudicated using the D-index derived from the data harvested from OpenAlex and CrossRef — two of the most prominent, reliable, and widely regarded bibliometric databases accessible to the global research community.
