“…Exposure to high manganese impairs the lobster's antennular ficking activity, causing disorientation and inability to locate food (Krång & Rosenqvist, 2006). Likewise, unhealthy blue crabs, Callinectes sapidus, have been found in a manganesecontaminated area of North Carolina, USA (Gemperline et al, 1992;Weinstein et al, 1992).…”

“…metallurgic/chemical/agrochemical products, municipal wastewater discharges, etc) received the attention of the scientific world that considered Mn as a potential emerging contaminant in the environment, especially in the marine milieu (CICAD 63, 2004;Pinsino et al, 2012). In marine organisms some studies showed that, an Mn overload causes toxicity, although the cause-effect evidence has not been well elucidated (Regoli et al, 1991;Krång and Rosenqvist, 2006;Oweson et al, 2008;Oweson and Hernroth, 2009). Recently, we took advantage of the amenable model, the Mediterranean sea urchin Paracentrotus lividus, to investigate the potential toxicity of Mn on embryonic development, using biological and biochemical approaches.…”

a b s t r a c tIn the marine environment, manganese represents a potential emerging contaminant, resulting from an increased production of manganese-containing compounds. In earlier reports we found that the exposure of Paracentrotus lividus sea urchin embryos to manganese produced phenotypes with no skeleton. In addition, manganese interfered with calcium uptake, perturbed extracellular signal-regulated kinase (ERK) signaling, affected the expression of skeletogenic genes, and caused an increase of the hsc70 and hsc60 protein levels. Here, we extended our studies focusing on the temporal activation of the p38 mitogen-activated protein kinase (p38 MAPK) and the proteolytic activity of metalloproteinases (MMPs). We found that manganese affects the stage-dependent dynamics of p38 MAPK activation and inhibits the total gelatin-auto-cleaving activity of MMPs, with the exclusion of the 90e85 kDa and 68e58 kDa MMPs, whose levels remain high all throughout development. Our findings correlate, for the first time to our knowledge, an altered activation pattern of the p38 MAPK with an aberrant MMP proteolytic activity in the sea urchin embryo.

“…Weissburg (2011) suggests that in blue crabs chemoreceptors on the walking legs are involved in odour plume tracking. They rely on chemoreception in their food search (Krang and Rosenqvist, 2006). The first and second walking legs probe the ground and use the small chelae to pick up food items detected by leg chemoreceptors (Derby and Atema, 1982).…”

“…Once near the food source the taste receptors are important in selecting and ingesting edible food. First responses to food include antennule 'flicking' (a behaviour that is analogue to sniffing in mammals as it enhances sensitivity to chemical stimuli; Schmitt and Ache, 1979) and antennal sweeps, followed by olfactory tracking (Krang and Rosenqvist, 2006). Food is transferred to the maxillipeds where it is further checked by taste receptors and passed on to the mouth (Derby and Atema, 1982).…”
