For each year, means within the column followed by the same letter (lower case, capitals, and lower case in bold for 2016, 2017, and 2018, respectively) are not significantly different (p > 0.05). Minor fatty acids such as cis-11-eicosenoic, cis-11,14-eicosadienoic, behenic, arahidic, and lignoceric acids were not evaluated.
