and in stomachs of larval razorback sucker from the backwater (open, right); + indicates <1%; index of selection, L, indicated where
/L./ > about 10 (see text). A. Total zooplankton: water column n = 382 potential food items, larval stomachs n =1,020 food items. B.

food items, larval stomachs n = 427 food items. D. Daphnia: water column n = 49 potential foods items, larval stomachs n =181 food
items. E. Copepoda: water column n = 61 potential food items, larval stomachs n =165 food items.
