There are several different citation "styles"; each one has its own manual or handbook of guidelines describing the proper way to format a paper or another type of written work for publication. Some of the most common publication styles are APA and MLA. Ecology is the style preferred by the professors teaching Bio 160. Be sure to use the style required by your instructor.

Ecology Style refers to the citation format established by the Ecological Society of America. The best way to determine the appropriate format is to look a recent copy of the journal Ecology and use the references in the "Literature Cited" section which can be found at the end of every article.

APA Style refers to the citation format established by the American Psychological Association. The link, APA Format will provide examples of how to cite various resources using APA style. For more information consult the Publication Manual of the American Psychological Association, (call number BF 76.7.P83 2001, available in Reference and on Dictionary Stands throughout the Library).
