Fish isotopic niches associated with environmental indicators and human disturbance along a disturbed large subtropical river in China
Original language description
Stable isotopes are increasingly used to detect and understand the impacts of environmental changes on riverine ecological properties. The delta C-13 and delta N-15 signatures of fishwith different feeding habits were measured in a large subtropical river to evaluate how fish isotopic niches respond to environmental gradients and human disturbance. From basal resources to fish consumers, the high values of epilithic periphyton (biofilm) delta C-13 and suspended particulate organic matter delta N-15 concurrently determined the niche ranges and space (e.g., convex hull area) of fish communities. Along a longitudinal gradient (except in the industrial zone), the number of fish trophic guilds identified by Bayesian ellipses continuously increased, meanwhile, higher trophic diversity and less redundancy were observed near the lower reaches and estuary. Variance inflation factors were estimated to detect the multicollinearity of 40 environmental variables, 14 of which were selected as indicators. Relative
