Owing to their evolutionary history, the subphylum Crustacea unites extant species from widely differing osmotic environments like marine, estuarine and fresh waters, including habitats of varying salinity. Crustaceans compensate physiologically at both the systemic and cellular levels for osmotic and ionic challenges arising in their surrounding aquatic media, providing osmotic and ionic…
Binding of red pigment concentrating hormone (RPCH) to membrane receptors in crustacean chromatophores triggers Ca2+/cGMP signaling cascades that activate cytoskeletal motors, driving pigment granule translocation. We investigate the distributions of microfilaments and microtubules and their associated molecular motors, myosin and dynein, by confocal and transmission electron microscopy, …

Owing to its evolutionary history, the family Palaemonidae unites extant species from widely distinct osmotic environments like marine, estuarine and fresh waters, including osmotically stable or variable habitats. These shrimps compensate physiologically for osmotic challenge at both the systemic and cellular levels, employing homeostatic mechanisms that regulate the water and electrolyt…
Crustaceans hyper-osmoregulate in dilute media or freshwater using mechanisms of isosmotic intracellular and anisosmotic extracellular regulation. The latter involves the active transport of salt into the hemolymph, maintaining an osmotic concentration well above that of the surrounding medium. This salt uptake mechanism is based on the activity of an ion transporting protein, the Na+/K+-…
Crustaceans are extremely diverse and widely distributed. The survival and success of this group is the result of the differential selection of physiological mechanisms that provide a stable internal osmotic and ionic environment that protects the cells and tissues against the salinity fluctuations. This osmotic homesostasis appears to have allowed the conquest of the most variable enviro…

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…
