Data Sources and Citation Metrics Collection
The 5th edition of the Research.com Best Ecology and Evolution Scientists in Indonesia Ranking was developed using comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple other authoritative databases. These sources provide extensive coverage of scholarly publications and citation records across disciplines. The bibliometric data used to devise the citation-based metrics, integral to the ranking’s formulation, were collected on 2026-01-12, ensuring the dataset reflects the most up-to-date scholarly impact available at that time.
Each scientist’s position in the ranking is determined using their D-index (Discipline H-index), a refined metric that accounts exclusively for papers and citation metrics confined to the examined discipline. This specialized focus enables an accurate representation of a researcher’s influence specifically within Ecology and Evolution, rather than their overall scholarly output.
Scope and Criteria of the Ranking
In assembling the ranking, a total of 279,971 scientist profiles across all fields were evaluated from a diverse array of bibliometric sources, among which 6 scientists specialized in Ecology and Evolution were closely examined. To qualify for inclusion in this ranking, a scientist’s D-index had to meet a minimum threshold of 30. Additionally, the majority of their tier publications needed to pertain directly to Ecology and Evolution, ensuring relevance in the assessed domain. Awards and notable achievements specific to Ecology and Evolution were also taken into account as supplementary evidence of domain expertise and contribution.
The D-index threshold is dynamically calibrated in increments of 10, tailored to the estimated total number of scholars within each discipline. This approach ensures that the ranking consistently incorporates the top 1% of leading experts in their respective fields. Furthermore, a proximity criterion is applied, whereby the difference between a researcher’s overall H-index and their D-index must remain at 30% or less. This requirement guarantees that the researcher’s disciplinary impact is closely aligned with their broader scholarly influence, underscoring specialization.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot fully encapsulate a scholar’s scientific output, the Research.com team conducted exhaustive manual verification of all scientist profiles considered for the ranking. Each profile was cross-correlated against publications verified through a wide range of reliable and authoritative sources to ensure accuracy and legitimacy.
While not a formal metric influencing a researcher’s rank, the quantity of publications in prominent journals and respected conference proceedings was acknowledged as a valuable secondary indicator of scientific contribution within Ecology and Evolution. The final ranking positions were established based on each researcher’s D-index, derived from data in OpenAlex and CrossRef—two of the most widely recognized and trusted bibliometric databases accessible to the academic community.
