Citation style for the Bio 1B Research Skills assignment

Citation style for the Bio 1B Research Skills assignment

The citation style for the Bio 1B Research Skills assignment is based on the style of the journal BioScience. Citations for the assignment should follow the format given below.

Please note: In the citations for this assignment:

  • Date of publication: should not include the month or day
  • Journal names: do not include the name of the city of publication if it is given in parentheses
    Example: Nature (London) should be cited as Nature, since (London) is not actually a part of the journal name
  • Author names:
    • Separator: In a list of multiple authors, the names are separated by a comma and a space unless the author is the last author listed, in which case the author name is followed by a period.
    • Suffixes: If "Junior" or "III," "IV," etc. are a part of an author's name the suffix should be included after the author's initial(s) without a preceding comma or concluding period (unless the author is the last author listed, in which case a period terminates the entire list of author names).
      Example: Manoel G.C. Gondim, Jr., should be cited as Gondim MGC Jr
    • First initial and middle name: If an author goes by their first initial and middle name, do not change the order of the author's initials.
      Example: M. Night Shyamalan should be cited as Shyamalan MN.
    • Hyphenated first names: If an author has a hyphenated first name it should be cited with two initials.
      Example: Jean-Marc Landry should be cited as Landry JM
    • Hyphenated family name: If an author has a hyphenated family name it should be cited in full, including the hyphen.
      Example: Carrie-Ann Haydu-Houdeshell should be cited as Haydu-Houdeshell CA
    • Multiple family names: If an author has multiple family names they should all be listed in full.
      Example: Gabriel Garcia Marquez should be cited as Garcia Marquez G
    • Diacritical marks: If an author's name includes diacritical marks, omit them for this assignment only (edX Edge can't parse diacritical marks).
      Example: Jenő Kontschán should be cited as Kontschan J
