Data Sources and Citation Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Israel Ranking is derived primarily from comprehensive bibliometric data aggregated from OpenAlex and CrossRef, supplemented by multiple additional data sources to ensure robustness and breadth of coverage. The citation-based metrics that form the foundation of the ranking were collected on January 12, 2026, providing a current and reliable snapshot of scientific output. A researcher’s position in this ranking is determined by their D-index (Discipline H-index), a specialized metric that considers only the publications and citations relevant to the examined discipline, thereby providing a focused and discipline-specific measure of scientific impact.
Scope and Criteria of the Ranking
The scope of the ranking encompasses a thorough examination of 279,971 scientist profiles identified from diverse bibliometric databases across all scientific disciplines. Within the specific domain of Ecology and Evolution, 48 scientists were evaluated in detail. To qualify for inclusion in the ranking, a scientist's D-index had to meet a minimum threshold of 30, and the majority of their tier publications were required to be dedicated to Ecology and Evolution. Additionally, awards and notable achievements in the field were carefully considered to complement the citation-based assessment.
The threshold for the D-index is dynamically set as increments of 10, reflecting the estimated population size of researchers within each discipline, while ensuring that the top 1% of leading scholars are incorporated into the list. Another critical qualification for this rigorous ranking is that the proximity between a scientist’s general H-index and their D-index should not exceed 30%, underscoring the focus on discipline-specific impact.
Verification and Validation Processes
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly contribution, the Research.com team undertakes meticulous manual verification of all profiles incorporated into the ranking. Each scientist’s publication record is cross-correlated against publications available in a wide range of reputable and verified sources to confirm authenticity and relevance. While the number of papers published in prominent journals and conference proceedings is not a direct factor influencing the ranking position, it remains an important secondary indicator of a researcher’s contribution within Ecology and Evolution.
The authoritative position of each scientist in the ranking is established solely through the calculated D-index from data curated within OpenAlex and CrossRef, recognized as the most prominent and trusted bibliometric databases accessible to the research community worldwide.
