ABSTRACT Minuca mordax is a model for studies on ocean acidification and sea-level rise because lives in mangroves and riverbanks with low pH. We investigated the physiology of the crabs exposed to differents pH (6.5 and 5.8) and salinity (25, 30, 35, 40 45S). There was not mortality or alterations in the hypo-osmoregulation, suggesting that the factors did not affect salt absorption/secretion. Reduced pH changed metabolism, ammonia excretion, and hepatosomatic index in relation to the animals kept in control pH. At elevated salinities, metabolism increased when animals were kept in control pH, but it decreased when they were exposed to acidified pH. energy substrate, varied between proteins to a mixture of proteins and lipids. Important physiological parameters, related to the catabolism of amino acids and to the energy demand are changed and the consequences might include alterations in growth and reproduction due to the energy channeling to limiting processes of homeostasis.

pH 值降低和盐度升高会影响潮间带蟹 Minuca mordax（甲壳纲、十足目）的生理机能

摘要 Minuca mordax 是研究海洋酸化和海平面上升的模型，因为它生活在低 pH 值的红树林和河岸。我们研究了暴露于不同 pH（6.5 和 5.8）和盐度（25、30、35、40 45S）的螃蟹的生理机能。低渗透调节没有死亡或改变，表明这些因素不影响盐的吸收/分泌。与保持在控制 pH 值的动物相比，降低的 pH 值改变了代谢、氨排泄和肝体指数。在盐度升高的情况下，当动物保持在控制 pH 值时新陈代谢增加，但当它们暴露于酸化 pH 值时代谢减少。能量底物，在蛋白质之间变化到蛋白质和脂质的混合物。重要的生理参数，
