Data Sources and Ranking Methodology
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Turkey Ranking is constructed primarily on comprehensive bibliometric data obtained from OpenAlex and CrossRef, supplemented by multiple additional reputable data sources. The citation-based metrics used to devise this ranking were rigorously collected on January 12, 2026, ensuring the timeliness and relevancy of the dataset. A scientist’s position within this ranking is determined by their Discipline H-index, or D-index, which reflects the impact of their scholarly output specifically within the examined discipline of Ecology and Evolution. This metric exclusively incorporates papers and citation data pertinent to this field, providing a focused and nuanced measure of disciplinary impact.
Scope of Research and Qualification Criteria
The ranking is derived from an exhaustive examination of 279,971 scientist profiles aggregated from diverse bibliometric data sources, spanning all academic disciplines. Within this extensive dataset, 2,000 scientist profiles from the Ecology and Evolution domain were specifically evaluated. To qualify for inclusion, researchers were required to possess a D-index of at least 30, ensuring a baseline of significant scholarly contribution. Additionally, the majority of their Tier 1 publications needed to be concentrated in Ecology and Evolution to maintain disciplinary relevance. Recognized awards and achievements in the field were also taken into account as an ancillary metric, reflecting qualitative excellence alongside quantitative impact.
The threshold for the D-index is calibrated in increments of 10, tailored to the estimated population of scholars in each discipline, while guaranteeing that the top 1% of leading experts are represented accurately. Furthermore, it was essential that the proximity between a scientist’s general H-index and their D-index not exceed 30%, maintaining consistency between their overall and discipline-specific research impact.
Additional Verification Practices
Recognizing the inherent limitations of raw bibliometric data as an absolute measure of scholarly output, the researchers behind this ranking have implemented a thorough manual verification process. Each scientist’s profile was meticulously cross-correlated against publications from a broad spectrum of trustworthy and authoritative sources to confirm accuracy and authenticity.
Although the volume of research published in prominent journals and conference proceedings does not directly influence position in the Research.com ranking, it serves as a valuable secondary indicator of a scientist’s contribution to their field. The primary metric remains the D-index, established strictly using data from OpenAlex and CrossRef—two of the most prominent and reliable bibliometric databases available to the international research community.
