Wisconsin School

Wisconsin School A group of ecologists, led by J. T. Curtis and his associates, who developed a range of simple ordination methods in 1950 and later, while studying the vegetation of Wisconsin. In the most widely applied scheme, density–frequency-dominance (DFD) values are estimated for all species recorded in the field. Importance values derived from these enable identification of leading dominants. Stands with the same leading dominant are grouped together and importance values for all species recalculated within the groups. These values are used to assign climax adaptation numbers and subsequently a continuum index is derived. Later developments, notably by Bray and Curtis (1957), improved the way in which stand similarities were expressed and portrayed graphically, by using a similarity index calculated from stand data rather than using the subjectively assessed continuum index. See also COEFFICIENT OF SIMILARITY.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
