Abstract
Four sympatric ecomorphs – detritivorous, predator, benthivorous, and phytophagous – of the cyprinid fish Schizopygopsis stolickai were recorded in a young Pamir lake, Lake Yashilkul, located at > 3,700 m above sea level. Some ecomorphs are divergent in diet, gut length, and stable isotopes of δ13C and δ15N. The predator ecomorph has a shorter gut, and is the most enriched in δ15N (14.5‰), indicating its occupation of the highest trophic level. The lowest δ15N values (11.1‰) were detected in the detritivorous ecomorph. There was significant overlap in the diet of some individuals belonging to different ecomorphs, reflecting high trophic plasticity despite ongoing trophic specialization.
