In fact Riv. Biol. is in principle soley a commentary journal directed mostly to an Italian audience...
Founded in 1919, RIVISTA DI BIOLOGIA / BIOLOGY FORUM is one of the oldest biological journals in the world. It published articles by many prestigious Italian and international authors (such as E. Giglio-Tos, D. Rosa, J. Eccles, B. Goodwin, G. Webster, R. Thom, F. Varela, A. Lima-de-Faria).
It publishes researches in the fields of Theoretical Biology, in its broadest sense. It aims at going beyond specializations, discussing, before a multidisciplinary audience, biological subjects of general interest.
Rivista di Biologia / Biology Forum publishes researches in all fields of biology (such as Evolutionary Biology, Developmental Biology, Genetics, Biophysics, Biomathematics, History of Biology etc.), provided they are of general theoretical interest.
Articles are in English, with an Italian summary. A news section (mainly in Italian) publishes book reviews, brief news and readers' letters (letters, either in English or in Italian, may be sent to
according to the journal..articles are generally invited though they do accept other submissions....
It is not clear to me from the instructions that the articles are peer reviewed but rather edited for language..
Language revision. When requested by authors, editors or referees, Rivista di Biologia / Biology Forum may have papers revised by English-speaking translators. Revision costs will be charged to the authors.
I would hesitate to define the journal as purely fringe as they do deal with rather normal discussions of biological importance..from the latest issue
Gian Luigi Mariottini and Luigi Pane Ecology of Planktonic Heterotrophic Flagellates. A Review Abstract
Sergio Pennazio Photosynthesis: A Short History of Some Modern Experimental Approaches Abstract
...a better term for this journal would be extremely obscure. Otherwise, it seems like an Italian version of New Scientist or something equivalent...I cannot say 100% for certain as my attempts to read abstracts lead me to dead links.
I would consider a more fringe journal to be something that might have "UFO's and their effects on intelligent designed polymerization of DNA chains by I.P. Freely and I.M. Clueless" or "Biblical Flood Modelling: Passing gas in the bathtub as a theoretical framework for proving the Flood" as a standard type of article.
