Data Sources and Metric Basis
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Poland Ranking is primarily compiled using comprehensive bibliometric data obtained from OpenAlex and CrossRef, supplemented by multiple other authoritative data sources. These platforms provide extensive and robust coverage of scholarly publications, citations, and related metadata. The bibliometric data used for devising the citation-based metrics underlying the ranking were collected on January 12, 2026, ensuring recency and relevance.
A scientist's position in this ranking is determined by their Discipline H-index (D-index), which assesses only those publications and citation metrics pertinent to the Ecology and Evolution discipline under examination. This focused approach isolates a researcher's impact within the specific field, offering a precise measure of scholarly influence aligned with academic specialization.
Scope of Research and Qualification Criteria
The ranking examines a total of 279,971 scientist profiles identified through an extensive survey of bibliometric databases across all research domains. Specifically, 34 scientists engaged in Ecology and Evolution were analyzed. To be considered for the ranking, a researcher must have a D-index of at least 30, with a majority of their tier publications falling clearly within the domain of Ecology and Evolution.
In addition to citation metrics, scientists' awards and achievements relevant to Ecology and Evolution were factored into the evaluation process. The D-index threshold for inclusion is dynamically calibrated in increments of 10, corresponding to the estimated total population of scholars in each discipline. This approach ensures that the top 1% of leading experts are systematically captured within the ranking. Furthermore, the methodology maintains a proximity criterion, requiring the difference between a scientist’s general H-index and their D-index not to exceed 30%, thus guaranteeing substantive engagement in the focal discipline.
Additional Verification Practices
Recognizing the limitations of quantitative data alone, the research team has performed meticulous manual verification of all scientist profiles. Each profile has been cross-correlated against publications indexed in a broad array of trustworthy sources, enhancing the validity and credibility of the dataset.
While the ranking’s positional decisions rely exclusively on the D-index derived from OpenAlex and CrossRef, ancillary factors such as the number of papers published in prominent journals and conference proceedings serve as valuable secondary indicators of a scientist's substantive contribution to Ecology and Evolution. These additional signals, although not directly influencing rank order, contribute to the holistic evaluation of the individual’s academic impact.
Position calculations utilize the most prominent and widely recognized bibliometric repositories available to the research community, reinforcing the robustness of the ranking data.
