Abstract

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值降低和盐度升高对潮间带蟹(Minuca mordax)生理机能的影响

摘要:海蟹(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的红树林和河岸。我们研究了不同pH(6.5和5.8)和盐度(25、30、35、40 45S)下海蟹的生理特征。低渗透调节无死亡或改变，表明这些因素不影响盐的吸收/分泌。与控制pH值的动物相比，降低的pH值改变了动物的代谢、氨排泄和肝体指数。在升高的盐度下，动物在控制pH值时代谢增加，但当它们暴露于酸化的pH值时代谢减少。能量底物在蛋白质和蛋白质和脂质的混合物之间变化。与氨基酸分解代谢和能量需求有关的重要生理参数发生了变化，其后果可能包括由于能量输送到限制稳态过程而导致的生长和繁殖的改变。

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
