Coverage1973-1977, 1979-ongoing
Scope Established in 1920, Ecology publishes research and synthesis papers on all aspects of ecology, with particular emphasis on papers that develop new concepts in ecology, that test ecological theory, or that lead to an increased appreciation for the diversity of ecological phenomena. Theoretical, analytical, experimental, empirical, historical, and descriptive approaches are all appropriate, though preference is given to research and synthesis that leads to generalizations potentially applicable to other species, populations, communities, or ecosystems. Included within the journal are papers on physiological responses of individual organisms to their biotic and abiotic environments, ecological genetics and evolution, the structure and dynamics of populations.

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.

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.
