16 Methods (cont.) You may want to organize this section into subsections. Example: Field sampling Laboratory methods Statistical analyses From KLCreative Media

17 Methods (cont.) Should be written in the past tense. From Fandel et al. (2015). From Fandel et al. (2015).

18 Methods (cont.) Include Figures (e.g., picture, map, diagram) if necessary. i. Are numbered sequentially (ex. Fig. 1, Fig. 2). ii. Typically cited within parentheses in the text. But can be cited as follows From Goddard et al. (2016). From Goodward et al. (2017).

19 Methods (cont.) Include a figure caption (place at the bottom of the figure). From Fandel et al. (2015). *Use Fig., NOT Figure in the caption!
