Best Ecology and Evolution Scientists 2026 in Bulgaria

A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric measure that considers only those papers and associated citation metrics strictly within the discipline of Ecology and Evolution. This discipline-specific index offers a more targeted and precise assessment of a researcher’s impact in the field, as opposed to a general H-index which aggregates influence across all scientific areas.

Scope of Research and Eligibility Criteria

The ranking derives from an extensive evaluation of 279,971 scientist profiles spanning all disciplines, within which 1,000 scientists specifically specializing in Ecology and Evolution were identified and examined. To qualify for inclusion in the Ecology and Evolution ranking, a researcher must have a D-index of at least 30, which highlights a significant level of scholarly achievement within the discipline. Additionally, the majority of a qualifying scientist’s tier publications are required to be focused on Ecology and Evolution, ensuring disciplinary relevance and consistency.

Beyond bibliometric indicators, awards and notable achievements in Ecology and Evolution also inform the assessment, adding qualitative dimension alongside quantitative metrics. The D-index threshold for considering top researchers is dynamically set in increments of 10 and is scaled depending on the estimated total number of scholars within each discipline. This methodology guarantees that the ranking incorporates the top 1% of leading experts. Moreover, to maintain methodological rigor, there is an enforced proximity criterion whereby the difference between a scientist’s overall H-index and their D-index does not exceed 30%, maintaining coherence between general and discipline-specific impact.

Verification and Quality Assurance

The Research.com team acknowledges that raw bibliometric data alone can never serve as an absolute measure of scholarly output or influence. To enhance the accuracy and reliability of the ranking, all scientist profiles underwent meticulous manual verification. This included cross-correlation of publication records against a broad set of trusted and established sources to ensure data integrity and correct attribution.

While not a direct factor in determining ranking position, the volume of publications in prestigious journals and top-tier conference proceedings serves as an important secondary indicator of a scientist’s contribution to Ecology and Evolution. This complementary signal supports the overall evaluation by highlighting the visibility and impact of their research.

The final ranking positions are established exclusively by each researcher’s D-index, computed using detailed citation data from OpenAlex and CrossRef—two of the most authoritative and widely recognized bibliometric databases available to the global research community. For a comprehensive explanation of the methods used, we invite readers to consult our methodology page, which details the entire analytical framework behind the ranking.
