Environmental Science

This is a guide to CSE style, used for your Biology research paper. At the end of your paper, your citations are alphabetized and then numbered. For more information, refer to the handouts from your professor.

In the citation-name system, number your sources alphabetically by each author’s last name in the reference list at the end of your paper. In the sentences of your paper, cite these sources using the number from the reference list. This means that the in-text citation 1 refers to the first source in your alphabetical list.
Example from Charkowski (2012):Despite this, there has been significant progress in modeling gene regulation in SRE, including mathematical models of virulence 75 and examination of gene expression at the single cell level 87,158,159,166.

In the citation-sequence system, number your sources in the reference list at the end of the paper by the order in which you refer to them in your paper. In the sentences of your paper, cite these sources using the number from the reference list. This means that the in-text citation 1 refers to the first source mentioned in your text.
Example from Newbury (2013):These interactions have been implicated in many systems, including small molecules 4, peptides 5, proteins 6, peptoids 7, and nucleic acids 8.

In the name-year system, list (but do not number) your sources alphabetically in the reference list at the end of your paper. In the sentences of your paper, cite these sources by giving the author’s last name and year of publication in parentheses.
Example from Wattiaux (2005):Milk urea nitrogen can be used as an indicator of the adequacy of protein and the balance between energy and protein in lactating dairy cow diets (Broderick and Clayton 1997; Wattiaux and Karg 2004a) and as a predictor of urinary nitrogen excretion (Kauffman and St Pierre 2001; Kohn et al. 2002; Wattiaux and Karg 2004b).
