The 2nd edition of Research.com ranking of the best scholars in the
field of Ecology and Evolution relies os data
combined from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
takes into account only publications and citation
metrics for an examined discipline.
The focus of our Ecology and Evolution research
Our best scholars ranking is a trustworthy lineup of leading scientists from the area of Ecology and Evolution, established by means of a meticulous study of 166,880 scientists determined from multiple bibliometric data sources. For the discipline of Ecology and Evolution, over 11774 researchers were investigated.
What is D-index approval threshold for Ecology and Evolution
The D-index threshold for accepting a scientist to be considered is set to 30 if the majority of of their publications are in the field of Ecology and Evolution. The inclusion criteria for scientists to be considered into the ranking of top scientists are based on the D-index, proportion of the contributions made within the given discipline as well as the awards and achievements of the researchers. The D-index threshold for including leading scientists is set as an increment of 10 depending on the total number of researchers assessed for each scientific field whilst guaranteeing that the top 1% of leading scholars are added into the list. We estimate a proximity of 30% or less between a scientist’s general H-index and their D-index.
Additional verification practices
Since our leading goal is to guarantee that only credible researchers are mentioned in the ranking we are aware that raw data are never supposed to be a complete tool to quantify the output of scientists. For that reason we manually check each profile and cross-correlate it against publications in a wide range of credible sources. Even though it’s not a factor defining a researcher’s position in Research.com ranking, the number of documents published in well-known journals and conference proceedings should form a credible secondary implication of their contribution to research in a specific area of science. Position in the ranking is established using each scientist’s D-index using metrics compiled from OpenAlex and CrossRef, which are the most trustworthy and well-established bibliometric databases of this kind open to the scientific community. A comprehensive explanation of our research procedures can be found on our methodology page.
Our aim is to inspire researchers, companies and administrative bodies around the world to explore where leading experts are heading and to offer an opportunity for the whole research community to discover who the leading experts in specific areas of study, in various countries, or even within research institutions are.
