Abstract

ABSTRACT Amphibians are increasingly challenged with salinization due to factors such as elevated sea level associated with climate change, the use of road salts, and lowering of water tables. Aldosterone is a steroid hormone that is produced by the adrenal cortex and is involved in osmotic regulation and may play an important role in amphibian acclimation to elevated salinity. We studied the effects of salinity on growth, development, and aldosterone levels in Cuban treefrog (Osteopilus septentrionalis) tadpoles. Gosner stage, growth rates, and aldosterone levels were determined for tadpoles among three salinity treatments (1.0, 2.5, and 3.5 ppt) over a six-week period. It appears that Cuban treefrog tadpoles have the ability to respond to high salt levels with decreased aldosterone secretion; however, in order to survive high salt concentrations, trade-offs in growth and development must occur to regulate osmotic functions.

盐度升高对古巴树蛙septontrionosteopilus醛固酮水平、生长和发育的影响

由于气候变化导致的海平面上升、道路盐的使用和地下水位下降等因素，两栖动物面临着越来越多的盐碱化挑战。醛固酮是一种类固醇激素，由肾上腺皮质产生，参与渗透调节，可能在两栖动物适应高盐度中起重要作用。我们研究了盐度对古巴树蛙(Osteopilus septentrionalis)蝌蚪生长、发育和醛固酮水平的影响。在六周的时间里，测定了三种盐度处理(1.0、2.5和3.5 ppt)下蝌蚪的Gosner期、生长率和醛固酮水平。古巴树蛙蝌蚪似乎有能力对高盐水平做出反应，醛固酮分泌减少;然而，为了在高盐浓度中生存，生长和发育必须进行权衡以调节渗透功能。

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).
