Data Sources and Citation Metrics
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Turkey Ranking is grounded in comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple other reputable databases. These sources collectively provide robust and extensive citation information that underpins the ranking's citation-based metrics. The bibliometric data used to calculate these metrics were compiled on January 12, 2026, ensuring currency and relevance in reflecting researchers' academic impact.
A scientist’s position in the ranking is determined by their Discipline H-index (D-index), a specialized metric that accounts solely for publications and citations pertinent to the Ecology and Evolution discipline. This approach allows for an accurate assessment of scholarly influence within this specific field, filtering out unrelated academic output to enhance precision.
Scope of Research and Selection Criteria
The ranking encompasses an examination of 279,971 scientist profiles drawn from diverse bibliometric repositories, spanning all scientific disciplines. Within this expansive dataset, two distinguished scientists specializing specifically in Ecology and Evolution were identified and analyzed.
To qualify for inclusion, a researcher’s D-index had to meet or exceed a threshold of 30, with a majority of their tier publications clearly situated within the Ecology and Evolution domain. Additionally, the scientists’ awards and achievements in this field were carefully considered to complement the bibliometric evaluation. The D-index thresholds are adaptively set in increments of 10 based on the estimated total number of scholars in each discipline, with the objective of encompassing the top 1% of leading experts. Furthermore, to ensure disciplinary focus consistency, the D-index and the general H-index of candidates maintained a proximity of 30% or less.
Additional Verification Procedures
Recognizing the limitations of raw bibliometric data as a sole evaluative tool, the researchers responsible for this ranking undertook meticulous manual verification of all scientist profiles. This process included cross-referencing publications against a wide array of trustworthy sources beyond the primary bibliometric databases. While publication volume in prominent journals and esteemed conference proceedings was not directly factored into ranking positions, it was acknowledged as a valuable secondary indicator of a researcher’s substantive contributions to Ecology and Evolution.
The final ranking positions derive from each scientist’s D-index, rigorously calculated using data from OpenAlex and CrossRef—the foremost and most widely trusted bibliometric databases accessible to the research community today.
