“…As stratified lakes are characterized by steep gradients, vertical heterogeneity over a small depth interval is evident. Even in shallow waters, minor differences in temperature between surface‐ and bottom‐water layers result in stably stratified water columns (Petrucio, Barbosa, & Furtado, ), as was found in floodplain lakes (Caraballo, Rider Forsberg, Ferreira de Almeida, & Galdino Leite, ; Marshall, ; Townsend, ) and river sections as well (Engel & Fischer, ). If the stratification of floodplain lakes persists during inundation, it might increase habitat heterogeneity and, consequently, enhance floodplain biodiversity (Ward, Tockner, & Schiemer, ).…”
