Molecular Ecology Resources

Molecular Ecology Resources encourages development of broad resources for the community including computer programs, statistical and molecular advances, and extensive molecular tools. The journal is a vehicle for dissemination of these resources, targeting a wide audience of researchers in the fields of evolution, ecology, and conservation. Articles in Molecular Ecology Resources are intended to facilitate studies addressing consequential questions in these fields. In addition to novel resource articles, Molecular Ecology Resources publishes relevant Reviews, Opinions, and Comments. The journal also publishes occasional Special Issues that emphasize development of resources in a particular area. Papers that report on empirical research in ecology, evolution, behavior, and conservation, rather than new resources and tools, should be submitted to our companion journal, Molecular Ecology. Papers that are primarily descriptive and relevant only to the taxon being studied without addressing a question more broadly applicable in ecology are not appropriate for Molecular Ecology and should instead be submitted to a more specialized journal or to Ecology & Evolution.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

External Cites per Doc

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
