Abstract
This study aims to clarify mechanisms of copper toxicity, accumulation and tissue distribution in the fiddler crab Uca rapax (Crustacea, Ocypodidea), a semi-terrestrial crustacean that inhabits a wide range of salinities. Our ultimate goal is to develop a Biotic Ligand Model approach and compare different pathways of metal uptake over a range of salinities after exposure to waterborne and…
