The 2nd edition of Research.com ranking of the best scholars in the
discipline of Ecology and Evolution is based on data
derived from various data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a scientist's
D-index (Discipline H-index), which only includes
papers and citation metrics for an examined discipline.
The range of our Ecology and Evolution research
Research.com’s best scientists ranking is a credible list of leading scientists from the field of Ecology and Evolution, based on a detailed study of 166,880 scholars determined from a variety of bibliometric data sources. For the area of Ecology and Evolution, over 11774 scientists were investigated.
What is D-index inclusion threshold for Ecology and Evolution
The D-index threshold for accepting a scholar to be evaluated is established at 30 if the majority of of their publications are in the field of Ecology and Evolution. The inclusion requirements for scholars to be considered into the ranking of top researchers are based on the D-index, proportion of the contributions made within the specific field of study plus the awards and achievements of the researchers. The D-index threshold for listing leading researchers is set as an increment of 10 depending on the total number of scientists estimated for each discipline whilst guaranteeing that the top 1% of leading scholars are incorporated into the list. There should be a proximity of 30% or less between a researcher’s general H-index and their D-index.
Other verification rules
Because our main aim is to make sure that only actual scientists are included in the ranking we are aware that raw data are never meant to be a complete tool to evaluate the output of scholars. This is why we manually verify every profile and cross-correlate it against publications in a varied range of reliable sources. Although it’s not a factor defining a scientist’s position in the ranking, the amount of papers published in major journals and conference proceedings should be a reliable secondary signal of their contribution to research in a given area of science. Position in the ranking is based on each scholar’s D-index using information collected from OpenAlex and CrossRef, which are the most credible and well-established bibliometric databases of this kind accessible to the research community. A detailed definition of our research policy can be found on our methodology page.
Our aim is to motivate scholars, companies and decision-makers around the world to examine where leading experts are heading and to give an opportunity for the whole research community to get to know who the leading experts in specific areas of study, in different countries, or even within research institutions are.
