The latest h-index of Trends in Ecology and Evolution is 312. The h-index is defined as the maximum value of h such that the given author/journal has published h papers that have each been cited at least h times. This index can be widely applied to the productivity and impact of a scholarly journal, individual researcher or a group of scientists, such as a department or university or country. The index was suggested in 2005 by Jorge E. Hirsch and is sometimes called the Hirsch index or Hirsch number.

H-Index | The h-index, or Hirsch index, measures the impact of scientists and journals. It is defined as the highest number of publications of a scientist that received h or more citations each while the other publications have not more than h citations each. For example, a scholar with an h-index of 5 had published 5 papers, each of which has been cited by others at least 5 times. The links below will take you to other areas within this guide which explain how to find an author's h-index using specific platforms.

The index works properly only for comparing scientists or journals in the same field, since citation conventions differ widely among different fields. H-index intends to address the main disadvantages of other bibliometric indicators, such as total number of papers or total number of citations. Total number of papers does not account for the quality of scientific publications, while total number of citations can be disproportionately affected by participation in a single publication of major influence (for instance, methodological papers proposing successful new techniques, methods or approximations, which can generate a large number of citations), or having many publications with few citations each. The h-index can simultaneously measure the quality and quantity of scientific output.
