Hystrix the Italian Journal of Mammalogy accepts papers on original research in basic and applied mammalogy on fossil and living mammals. The Journal is published both in paper and electronic "online first" format. Manuscripts can be published as full papers or short notes, as well as reviews on methods or theoretical issues related to mammals. Commentaries can also be occasionally accepted, under the approval by the Editor in Chief. Investigations of local or regional interest, new data about species distribution and range extensions or confirmatory research can be considered only when they have significant implications. Such studies should preferably be submitted as short notes. Manuscripts bearing only a local interest will not be accepted. Full papers have no limits in length as well as in figure and table number and are abstracted in English. Authors are encouraged to add supplemental material in form of colour figures, original datasets and/or computer program source code. Supplemental material and colour figures will appear only on the electronic edition. Short notes must be about 16000 characters long (including title, author names and affiliations, abstract and references), and do not include supplemental material. They are abstracted in English. Proceedings of symposia, meetings and/or workshops, and technical reports can be published as special supplements to regular issues, under the approval by the Editor in Chief and the Associate Editors. There are no page charges.
