In-text references and the reference list at the end of the paper should be prepared according to the Council of Science Editors (CSE) documentation Name-Year (N-Y) system.

In-text references should be cited in the form of the author’s last name and publication year in parentheses, e.g. (Nowak 2017). When a paper has two authors, it should be cited in parentheses as follows: (Nowak and Smith 2017).

When a paper has more than two authors, the first author’s name should be followed with “et al.” and the year of publication, e.g. (Nowak et al. 2002). While references occur that are not identified by the authors’ names and year, use a, b, etc., after the year (Nowak et al. 2002a; 2002b).

When you cite multiple works by different authors, put the sources in chronological order from oldest to most recent (and alphabetically, if published in the same year). Separate studies by a semicolon: (Nowak et al. 2008; Smith et al. 2016).

The list of the papers cited (Literature) is organized alphabetically according to the last name of the first author and not numbered. When there is more than one work by the author, those works are organized chronologically. Authors’ first names are rendered as capitals after their surnames as in an example: Nowak BS, Smith J, Coward PP. Papers with one only author are listed in chronological order (the earliest first); papers with two authors are listed alphabetically according to the last name of the first author and the last name of the second author. Papers with three or more authors appear as those with two authors and are listed chronologically.

Only the first word of a book or article title should be capitalized. Titles are not italicized. However, species names are italicized.

The Editorial Office strongly recommends using the dedicated software to manage and edit citations and literature. To easily adjust or change references according to the PJM requirements, choose a CSE citation style (N-Y option), which is build-in in these programs.
