Total lipid and total protein content (% of dry weight), wax esters (% of total lipids), composition of fatty alcohols (% of total fatty alcohols), and trophic positions according to Eglite et al. (2018) in two mesozooplankton size fractions from isolated water bodies (BW, bottom water; SW, surface water; WW, winter water) at the Eastern Gotland Basin in July 2014 and 2015. Note that mesozooplankton from the BW was sampled only in 2014
