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.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?

III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
