In-text references or citations are used to acknowledge the work or ideas of others. They are placed next to the text that you have paraphrased or quoted, enabling the reader to differentiate between your writing and other people's work. The full details of your in-text references must be included in a reference list.
Example:
Energy restriction without limiting other essential nutrients has been shown to increase lifespan (Merry and Holehan, 2002) without compromising reproductive performance (Johnston et al., 2006) in several species.
When the author's name appears in the sentence, it does not need to be repeated in the citation:
Example:
Lean growth rates, feed intake, efficiency data, and rates of pubertal development of these gilts are described by Miller et al. (2011).
