High environmental temperature and low pH stress alter the gill phenotypic plasticity of Hoven’s carp Leptobarbus hoevenii

Climate warming and low pH environment are known to negatively impact all levels of aquatic organism from cellular to organism and population levels. For ammonotelic freshwater species, any abiotic factor fluctuation will cause disturbance to the fish, specifically at the gills which act as a multif...
