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 agenda
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.
