Comparative Proteomics of Salinity Stress Responses in Fish and Aquatic Invertebrates
PROTEOMICS, EarlyView.ABSTRACT Fluctuating salinity is symptomatic of climate change challenging aquatic species. The melting of polar ice, rising sea levels, coastal surface and groundwater salinization, and increased evaporation in arid habitats alter salinity worldwide. Moreover, the frequency and intensity of extreme weather events such as rainstorms and floods increase,
